Hong Kong flu
Hong Kong flu

Description

This is an acute respiratory disease caused by the H3N2 influenza virus by A. Clinical signs of the disease are damage to respiratory and digestive systems, as well as a high temperature that stopped working. The symptoms of this type of influenza are dry cough, sore pain, headache, nasal congestion, severe weakness, dyspepsia. Diagnostics includes methods for detecting the pathogen in body fluids, as well as antibodies to it. Treatment consists of etiotropic antiviral therapy and symptomatic methods (detoxification, antipyretic drugs, musolics and).

Additional facts

Hong Kong flu is a respiratory infection caused by a bird flu virus that mutated in the middle of the 20th century. For the first time, this pathology became known between 1968 and 1969, when the first outbreak of this disease occurred in Hong Kong, Vietnam, Singapore, USA, Australia and some African countries with more than half a million deaths. Repeated mutation of the virus led to the appearance in 2016-2017. New outbreaks around the world. The seasonality of the disease is determined by the cold season (in autumn and winter); Most deaths and complications occur in early childhood (up to 5 years) and in old age (over 65 years).

Causes

The causative agent of the disease is the influenza type A virus (H3N2), which belongs to the Orthomyxovirus family. The causative agent is unstable in the environment, dies during the preparation when exposed to standard doses of disinfecting and ultraviolet solutions. The source of infection is a sick person. Transfer paths are in the air (with sneezing, coughing, cold) and in contact (when using hygienic accessories and cutlery without processing, non-compliance with the "cough label"). The risk groups of morbidity are children, elderly, pregnant women, people infected with HIV, patients with chronic somatic pathology and malignant neoplasms that receive immunosuppressive therapy. Medical workers, servicemen, students, schoolchildren, teachers, service sector employees. The spread of this nosology is widespread, but Southeast Asia is traditionally considered a high-risk region.

Pathogenesis

The penetration of the influenza virus into the epithelial cells of the nasopharynx, trachea, the bronchi is manifested by the massive destruction of epithelial cells, a decrease in the barrier function of the mucous membrane. The consequence of this is the injection of the pathogen, its metabolic products and cell necrosis. Neuraminidase and hemagglutinin proteins contained on the virus surface cause a neurotoxic effect and violation of the rheological properties of blood. Together, it has a pronounced intoxication effect, in severe cases leads to infectious toxic shock. A feature of the pathogenesis of Hong Kong flu is considered a quick immune response of the body to the presence of this virus and its more favorable course. Most likely, this effect is associated with the antigenic structure of the pathogen and the characteristics of immunity. It has been proven that antibodies to neuraminidase are preserved in the human body up to 20 or more years, and protective proteins for hemagglutinin are also stored for such a long time.

Symptoms

The incubation period of the infection is 1-2 days. The disease is characterized by a rapid beginning, a longer flow (from 10 to 14 days) and pronounced symptoms of intoxication. Debit the disease is acute with a sharp increase in body temperature (up to 39.5 ° C and higher), while the patient may often even specify the exact time when the deterioration of well-being begins. Soon there are headaches, redness of the eyes, pain when moving with eyeballs, strong chills, muscle pain and joints, stomach disorder (nausea, rare vomiting, liquid chair up to 10 or more times a day), decreased appetite and severe weakness. A day or two, the sore throat appears, nasal congestion and dry cough. Dangerous symptoms to predict the pathology flow are considered to be a violation of productive contact with the patient, episodes of cramps and loss of consciousness, the beginning of the fountaining vomiting at the height of the headache, the progressive muscular weakness of the limbs, the appearance of nasal, gum, bleeding organs and small rashes on the tips (Petechia) on the body, Strengthening respiratory failure (shortness of breath, acricyanosis), reducing urine. Associated symptoms: Water diarrhea. High body temperature. Hematuria. Nasal congestion. Cough. Leukopenia. Lymphocytosis. Lymphocyting. Fever. Malaise. Night sweats in women. Dyspnea. Chills. Lack of appetite. Sore throat. Sweating. Proteinuria. Vomiting. Cramps. Nausea.

Possible complications

Timely appeal for medical care and the reception of effective drugs almost always eliminate possible complications. The most common effects of influenza are bacterial inflammatory processes in various organs and systems. First of all, this is pneumonia, inflammation of the sinuses (sinusitis, frontal sinusitis), the average otitis, as well as pyelonephritis, myocarditis, less often - meningoencephalitis, infectious-toxic shock. In addition, many diagnostic and therapeutic manipulations may lead to impaired integrity of the skin and mucous membranes and cause the appearance of local purulent processes (abscesses, phlegmon), as well as a generalized septic process in people with immunodeficiency.

Diagnostics

To diagnose influenza in Hong Kong, a consultation of a specialist in infectious diseases, a pulmonologist (after signs of damage to the lungs) and the gastroenterologist (with gastroenteritis) are required. If you suspect this type of influenza, the following diagnostic methods are used: • Objective control. Physical examination reveals the presence of respiratory failure (forced posture, shortness of breath, phenomena of acrocyanosis), deafness of the heart tones, degree of violation of consciousness, symptoms of damage to brain shells and brain substances. When studying the rotogling in the lungs, you can hear stagnation in the throat, the mucous membrane of the nose, single or diffuse dry cilia. • Laboratory blood tests. In general clinical analysis of blood, leukopenia, lymphocytosis, moderate acceleration of ESP are recorded. At the peak of fever with general analysis of urine, small proteinuria and microhematuria may appear (with a decrease in body temperature, these indicators are normalized). Biochemical blood test is usually within the physiological norm, you can see an increase in the CRP. • Identification of infectious pathogens. The diagnosis of PCR is carried out in the study of the secretion of the nose, sputum, nashablock smears, throat. Anti-virus antibodies are recorded using ELISA, while venous blood is collected twice with an interval of 2-3 weeks to detect an increase in antibody titer (in two or more times). Express tests (Sensitivity 99%, specificity 98-99%) exist for the diagnosis of influenza at home and in outpatient conditions based on the immunochromatographic method. The material of the study is usually nasopharynknoe content. • Radiation diagnostics. The radiography of the chest and the incomplete sinuses, the ultrasound of the abdominal cavity and kidney is necessary for the early diagnosis of infectious complications and the differential diagnosis of Hong Kong influenza. The differential diagnosis is raised with other acute respiratory viral infections, sepsis, meningococcal infection, abdominal typhoid tuberculosis, malaria, paratifa A and B, generalized salmonelles and abdominal typhoid. A similar clinical picture is observed in pneumonia, bronchitis, tonsillitis, the debut of diffuse diseases of the connective tissue, pyelonephritis, purulent processes in the abdominal cavity (liver abscesses), the retroperitoneal space (kidney carbuncoon), chest (accusable pleurisy), small pelvis (adnexitis).

Treatment

In the presence of clinical and epidemiological testimony, patients with suspicion of infection are subject to hospitalization, sometimes possible treatment at home. A special diet is not designed, often frequent fractional food, as well as dairy and vegetable products. Much attention is paid to the cessation of smoking (to improve gas exchange in the lungs) and the use of a large amount of fluid (mainly), since dehydration can occur with a long-term increase in body temperature, increased sweating. And dyspepsia. Bed regime is recommended to a steady reduction in body temperature within 2-3 days. Antiviral drugs that should be prescribed as soon as possible (on the first day of the disease and before that) are specific treatment for Hong Kong influenza. The most effective agents are oseltamivir, zanamivir, pentanthi imidazolyletamide. Currently, the Phase of clinical trials is the drug Balkaxavir. Tools of symptomatic therapy - detoxifying agents (glucose, saline, chloropic, trisole, rea -cerin), antipyretic agents (diclofenac, celecoxib), local antiseptics (furaciline solutions, chlorhexidine, calendula), mucolytic (acetylcysteine), nose drops. For phenomena of liquid chair, nausea and vomiting sorbents are prescribed (colloidal silicon dioxide, activated carbon, enzymes (pancreatin, lipase).

Forecast

FUGE POSSIBILIES IN HONKGONS is favorable, mortality does not exceed 0.5%, which is associated with possible immunity among people who were sick in the middle of the last century, a reduction in mass events (quarantine), the provision of proper medical care and the use of antiviral and antibacterial drugs. Timely treatment Bacterial complications).

Prevention

The only method of effective specific influenza prevention is vaccination. Vaccines contain surface antigens of the most important influenza viruses in the epidemic season (at least 15 μg of hemagglutinin in accordance with WHO Recommendations). Adding immunomodulators (polyoxy, joint) The flu vaccine against influenza has not demonstrated effectiveness. Non-specific influenza prevention is to avoid crowded places, use masks and respirators in the premises, maintain proper microclimate, wet cleaning, wash his hands and face with soap after arriving home.

Hong Kong flu

Hong Kong flu - This is a sharp respiratory disease caused by the H3N2 influenza virus by A. The clinical features of the disease serve the defeat and digestive system, as well as a poorly bought high fever. The symptoms of this type of influenza are dry cough, sore throat, headache, nasal congestion, pronounced weakness, dyspepsia. Diagnostics includes methods for detecting the pathogen in the biological fluids of the body, as well as antibodies to it. Treatment consists of etiotropic antiviral therapy and symptomatic methods (disinfecting, antipyretic drugs, musolics and others).

General

Hong Kong flu is an infection of the respiratory tract caused by a virus influenza in the middle of the twentieth century. For the first time about the pathology, it became known in 1968-1969, when the first outbreak of this disease in Hong Kong, Vietnam, Singapore, USA, Australia and some African countries with more than half a million fatal outcomes arose. Repeated mutation of the virus led to the emergence in 2016-2017. New outbreaks around the globe. Seasonality of the disease is determined by the cold time of the year (autumn and winter); The greatest number of deaths and complications fall on early children (up to 5 years) and elderly (over 65) age.

Hong Kong flu

Hong Kong flu

Causes

The causative agent of the disease is a type A flu virus (H3N2), belonging to the oltomiks family. The causative agent is unstable in the environment, dies during boiling, when exposed to standard doses of solutions for disinfection, ultraviolet irradiation. The source of infection is a sick person, the transmission path is the air-droplege (with sneezing, cough, a cold) and the contact (with the use of general hygiene objects and cutting devices without processing, non-compliance with "cough etiquette").

The risk groups in the incidence are children, senior, pregnant women, HIV-infected people, patients with chronic somatic pathologies, malignant neoplasms receiving immunosuppressive therapy; Medical workers, servicemen, students, schoolchildren, teachers, service staff. The prevalence of this nosology is ubiquitous, but Southeast Asia is traditionally considered a high risk region.

Pathogenesis

The penetration of the influenza virus into the epithelium cells of the nasopharynx, trachea, the bronchi is manifested by the massive destruction of epitheliocytes, a decrease in the barrier function of the mucous membrane. The consequence of this becomes the pathogen, the products of its livelihoods and necrosis of cells in blood. The neuraminidase and hemagglutinin proteins contained on the surface of the virus cause a neurotoxic effect and violation of the rheological properties of blood. All together has a pronounced intoxication effect, in severe cases, leading to infectious-toxic shock. A feature of the pathogenesis of Hong Kong influenza is considered a quick immune response of the body for the presence of this virus and more favorable during its course. Most likely, this effect is associated with the antigenic structure of the pathogen and the peculiarities of immunity. It has been proven that antibodies to neuraminidase are preserved in a person's body up to 20 or more years, protective proteins and hemagglutinin remains as long as long.

Symptoms of Hong Kong flu

The incubation period of the infection is 1-2 days. The disease is characterized by a rapid start, long flow (10-14 days) and pronounced symptoms of intoxication. Debit the disease is acute, with a sharp rise in body temperature (up to 39.5 ° C and higher), while the patient can often call even the exact time of the start of deterioration of well-being. Soon the headache is joined, redness of the eyes, pain when moving eyeballs, stunning olar pain, pain in the muscles and joints, digestive disorders (nausea, less often vomiting, liquid watery chair up to 10 or more times a day), decreased appetite and pronounced weakness. After a day, either two is added sore throat, nasal congestion, dry cough.

Dangerous symptoms for predicting the flow of pathology It is considered to be a violation of productive contact with patients, episodes of seizures and losses of consciousness, the emergence of a fountaining vomiting at the height of the headache, progressive muscle weakness in the limbs, the appearance of nasal, gantry, organ bleeding and finely purified (petechial) increasing respiratory failure (shortness of breath, acricyanosis), reduction of urine.

Complications

Timely appeal to medical care and the reception of effective drugs almost always level possible complications. The most frequent effects of influenza are bacterial inflammatory processes in various organs and systems. First of all, it is pneumonia, inflammation of the apparent sinuses (sinusitis, front), otitis, and also pyelonephritis, myocarditis, less often - meningoencephalitis, infectious toxic shock. In addition, many diagnostic and therapeutic manipulations can lead to a violation of the integrity of the skin and mucous membranes and cause the appearance of local purulent processes (abscesses, phlegmon), as well as a generalized septic process in immunodeficiency.

Diagnostics

For the diagnosis of Hong Kong influenza, the consultation of an infectiousnessist, a pulmonologist (after the appearance of symptoms of lungs), a gastroenterologist (with gastroenteritis). In suspected this type of influenza, the following diagnostic methods apply:

  • Objective inspection . The physical research allows you to identify the presence of respiratory failure (forced posture, shortness of breath, phenomena of acrocyanosis), the deafness of the heart tones, the degree of violation of consciousness, the symptoms of the brain sheath and the brain substance. In case of inspection of the o'clock, the hyperemia of the oz, the nasal mucosa is determined, single or diffuse dry wheels can be served in the lungs.
  • Laboratory tests of blood . In general blood test analysis, leukopenia, lymphocytosis, moderate acceleration of ESO are recorded. At the peak of fever, in general analysis of urine, minor proteinuria and microhematuria may appear (with a decrease in body temperature, these indicators are normalized). Biochemical testing of blood is usually within the physiological norm, an increase in CRB may be marked.
  • Detection of infectious pathogens . PCR diagnostics is carried out in the study of the nasal separated, sputum, nasophacks, throats. Antibodies to the virus are registered with the help of an ELISA, while taking venous blood is carried out twice with an interval of 2-3 weeks to detect the growth of antibody titer (double and more). There are express tests (sensitivity of 99%, specificity 98-99%) for influenza diagnosis in domestic and outpatient conditions based on the immunochromatographic method. The material for the study usually serves nasopharynk content.
  • Radiation diagnosis. Conducting the radiography of the chest organs and the apparent sinuses, the ultrasound of the abdominal cavity and the kidneys is necessary for the purpose of early detection of infectious complications and the diffidity of Hong Kong flu.

Differential diagnosis is carried out with other ODVI, sepsis, meningococcal infection, typhoid tuberculosis, malaria, parathy and in generalized salmonellosis, raw tit. A similar clinical picture is observed in pneumonia, bronchitis, tonsillitis, debuts of diffuse diseases of the connective tissue, pyelonephritis, purulent processes in the abdominal cavity (hepatic abscesses), the retroperitoneal space (kidney carbuncoon), the chest (squeezed pleurisy), small pelvis (adnexites).

Treatment of Hong Kong flu

In the presence of clinical and epidemic testimony, patients with suspicion of infection are subject to hospitalization, sometimes possible treatment at home. Special diet is not designed, often frequent fractional nutrition and milk-vegetable food. Much attention is paid to the abandonment of smoking (in order to improve gas exchange in lungs) and the use of a large amount of fluid (mainly regider or boiled water), since with a long-term increase in body temperature, reinforced sweating and dyspepsia can occur dehydration. Bed mode is recommended to a steady reduction in body temperature within 2-3 days.

Antiviral drugs are opposed to specific treatment of Hong Kong flu, which must be appointed as early as possible (the first day of the disease and earlier). The most effective means are oseltamivir, zanamivir, imidazolyetaniside pentandic acid; Currently, in the clinical trial stage is the drug Balkaxavir.

Means of symptomatic therapy are disintellation preparations (glucose, saline, chille, trisole, reasoberin), antipyretic agents (diclofenac, celecoxib), local antiseptics (furaciline solutions, chlorhexidine, calendula), mucolytics (acetylcysteine), vasoconductive drops in the nose and others. For phenomena of liquid stool, nausea, vomiting is prescribed sorbents (colloidal silicon dioxide, activated carbon), enzymes (pancreatin, lipase).

Prediction and prevention

The prediction in the Hong Kong influenza is favorable, mortality is not more than 0.5%, which is associated with possible immunity among those who have undergone disease in the middle of the last century, restricting mass events (quarantine), ensuring the proper medical care and the use of antiviral and antibacterial agents (for timely treatment of bacterial complications).

The only method of effective specific influenza prevention is vaccination. Vaccines contain surface antigens of the most relevant epidemic season of influenza viruses (at least 15 μg of hemagglutinin on WHO recommendations). Proven efficacy Adding immunomodulators (polyoxidonium, joint ventures) The flu vaccine has no flu. Non-specific influenza prevention is to avoid mass accumulation of people, using masks and respirators in the premises, maintaining adequate microclimate, wet cleaning, washing hands and face with soap after coming home.

The number of Hong Kong flu is growing in the Krasnoyarsk Territory. According to the forecasts of doctors, the peak of morbidity will have to January-February 2017.

This season, an average of the country, sharp viral diseases came out on the country, and not flu in itself. One patient with flu accounts for four to five patients who carry viral diseases of another nature: paragripp, adenoviral diseases, respiratory and sycitial virus, rinovirus, coronavirus. But precisely those viral diseases that flow as asthma-like states are prevalent: coughs, sickness with breathing, some people have a sense of light shortage in the development of such symptoms.

In Rospotrebnadzor, they clarify that the pathogens of the H3N2 type (Hong Kong) are mainly circulating among the population.

"Last year, the flu virus A (H1N1) PDM09 was prevailed, which in the people called the pork. This year we see that in more than 600 cases of a laboratory confirmed influenza disease from about 800 examined diagnosed flu virus A (H3N2). In the media, it is not quite correctly called Hong Kong, "write" Izvestia "with reference to the Senior Researcher of the Institute of Influenza of the Ministry of Health of the Russian Federation Igor Nikorov.

   1970s.

What is "Hong Kong flu"?

Influenza A (H3N2) is an acute viral infection that is transmitted by air-droplet. The birthplace of this infection is Asia. The epidemic caused by the H3N2 strain was first fixed in Hong Kong in 1968. Due to the mutation of the strain, the disease quickly spread. Elderly over 65 years of age suffered from the virus. Then thousands of people died from Hong Kong Flu.

Since then, the strain has not disappeared, but continued to circulate in the human population, becoming ordinary, seasonal. In 2014, the virus mutated again, the mortality rate became insignificant.

"Last year he came to us from the West, so I already met him. It is included in the list of recommended strains for vaccines. The fact is that the strain is called by the place where it was allocated. The name of the H3N2 virus coincided with the name of the influenza, which was highlighted in Hong Kong in 1968. But he is not so dangerous, "says Igor Nikonorov.

Hong Kong variety of influenza virus A / H3N2 A year ago, the inhabitants of the southern hemisphere were sick. Since September 2015, in this half of the globe, the strain was included in the composition of anti-influenza vaccines. It was a year, virologists and epidemiologists made conclusions and recommended making the "Hong Kong-2014" strain into the vaccine for residents of the northern hemisphere.

   1970s.

What is dangerous Hong Kong flu?

Do not forget the flu - this is not a simple cold. Any virus strain is dangerous enough. First of all, with its complications - up to severe lungs and hearts. It is because of these complications that the flu may end in death. Hong Kong option is no exception.

Hong Kong flu carries special risks for children of junior preschool age and for older people. His danger in complications that pathologically affect the cardiovascular system. Also, on the background of this influenza, pneumonia and meningitis may develop.

Those terrible cases when people die during the flu epidemic, taking the virus, are not connected with strain as such. Man's immunity during illness is weakened, and it is beneficial soil for the development of dangerous complications. It is from them that may have a fatal outcome.

"The virus actively multiplies and the blood current is distributed over all tissues. From here, sharp weakness, muscle and articular pains, high temperature - the whole immune system rushes to the fight against the virus, "explains the mechanism of the disease Nikolai Kontarov, a candidate of biological sciences, a leading researcher at the Vatician Vaccine Vaccine Research Center and serum. I.I. Mechnikov.

How is infection?

Finding on the mucous membrane of the upper respiratory tract, the virus is introduced into their epithelial cells, penetrates blood and causes intoxication. Conditions are created to activate their own bacterial flora, as well as to penetrate the outside of new pathogens, causing a secondary infection - pneumonia, bronchitis, otitis, the aggravation of chronic diseases, the heart can suffer, joints.

It must be remembered that the infection is easily transmitted through dirty hands. Special observations have shown that hands more than 200 times a day are in charge of separated from the nose and eye, with saliva. With handshake, through door handles, other items viruses go to the hands of healthy, and from there to them in the nose, eyes, mouth.

   1970s.

How does flu manifest?

On the first signs of the Hong Kong flu infection can say the same symptoms that we feel and with other types of virus: weakness, malaise, high temperature (up to 39 degrees) Headaches, chills, rubber and burning in the eyes, nasal congestion, dry cough, possible Also nausea caused by intoxication, vomiting, drowsiness.

In typical cases, the disease begins suddenly: temperatures increase to 38-40 degrees, chills appears, severe headache, dizziness, pain in the eyeballs and muscles, tearing and thread in the eyes.

How to avoid infection?

First of all, you need to limit your stay in the places of cluster of people. To prevent the disease, it is recommended to conduct vaccination. Influenza vaccine prevents severe forms of the disease.

During the epidemic, do not neglect the protective mask, especially if sick. It is possible to wear it no longer than 1.5 hours, then she herself becomes infection. It is worthwhile to wash not only the hands, but also wipe the gadgets, sising by bacteria. Coming home after the street and transport, you need to wash your nose to get rid of bacteria or viruses that are delayed for a while on the mucous membrane.

Traditional advice from all doctors without exception - do not self-medicate.

On July 13, 1968 in Hong Kong (then - the Colony of Great Britain) fell ill with the elderly vendor from the Mongkok district, which sold the crabs fried in the car oil on the street kiosk tray. It all started like a slight cuff, but after 2 days the temperature was rising under forty degrees, and a week later, a woman died. Already in mid-August, the hospitals in Hong Kong were crowded: 500 thousand were infected with a new sore (!) Man, people lay in the corridors, coughing with blood, and daft died every day. Businessmen and tourists brought infection in Singapore and South Vietnam, and from there who fought with the partisans-Communists American soldiers brought with them the virus in the United States. As now, mainly Hong Kong flu (or strain H3N2) more often killed people over 65 years old. This long-being forgotten pandemic took so many lives that they still cannot count exactly: the world was engaged in the "cultural revolution" in China, the Civil War in Nigeria, the resignation of the president Charles de Gaulle In France and the colossal losses of the American army in Vietnam. Researchers call numbers from one to four (!) Millions of the dead, but the real number may be much more ...

Infection through sweaty people

In fact, it was the first epidemic, laid around the world as soon as possible with the help of passenger and military aircraft. In America, the virus started with the Army bases of California, and for one month (December 1968) 50,000 infected patients died in hospitals. In general, the number of deaths among Americans is estimated at a hundred thousand people, almost as during the current coronavirus epidemic in the United States. It could be infect , only slightly touching a person: the infection was transmitted not only through the spray of saliva during the cough, but also through the sweat. It is unclear how exactly the virus broke out. Most virologists agree that the Spanish was transferred to a person from domestic birds (possibly chickens or ducks), the current coronavirus - from the wild animal (cobra or bat), but the origin of the "Hong Kong" - most likely, from small livestock Type of pigs. Surprisingly (as in the "Spanish") from the H3N2 virus, Japan suffered the least: the inhabitants of the rising sun, the masks of the rising sun were passionately in one day, strictly observed hygiene and any sanitary standards. At the neighboring Taiwan, a foreigner who came from the mainland was placed in quarantine for 2 weeks: the virus (and here again the similarity with COVID-19) was manifested mostly for 4-5 days, but sometimes lived in the body without symptoms of as much as 14 days. Not so many people died in Hong Kong itself, although no quarantine restrictions were introduced: doctors worked perfectly, including the early development of the vaccine in December 1968. No statistics on diseases in China. Probably there were many victims of Hong Kong flu, but it is impossible to calculate them. For Mao Zedune The PRC was a fully closed country, as North Korea, and did not provide the world any medical indicators.

Funeral with garbage collectors

But in Europe, the H3N2 virus turned on the full program. Most people died in Germany and the GDR: about 60,000 people (for comparison - from COVID-19 at the moment 8,600 patients died in Germany). In the morgues of Western Berlin there was no place, the corpses folded in the tunnels of inactive metro stations, to the funeral of the victims of the epidemic had to attract garbage collectors, as the gravers were missing. In France, 25,000 people died in December, in Toulouse had to stop the movement of trains, because 15% of railway employees got sick. In some parts of the country, half of the whole labor force (!) He fell into hospitals, and production in individual factories fell tightly because there was no one to work. Neither the press, nor the Government of France seriously did not take the Hong Kong flu, especially then there were unshakable confidence that any cough was treated with antibiotics: a purely virgist specialists knew about the differences between viral and cold pneumonia. The conviction was dominant: any infectious disease under control, modern medicine is capable of healing it. The virus hit the UK seriously: in some regions, within the framework of Quarantine, trains and buses between cities were stopped, but, nevertheless, several thousand people died from "Hong Kong".

Differences of the Soviet epidemic

The Soviet Union in the midst of a deadly pandemic was unheard of lucky. The USSR was a closed country, our tourists did not go with millions, as now, to relax for foreign resorts. The state was left only as part of organized tourist groups (after collecting the door of the approval of the party bosses and other documents) either at the invitation of a private person, during the long bureaucratic problems receiving an exit (!) Visa. Thus, H3N2 fell into the USSR not immediately and not massively, but "on the rubbish", at the very end of the epidemic in the whole rest of the world, when he has already weakened enough and did not make much harm. However, special use was published: employees of restaurants, hotels and other institutions working with foreign citizens (tourists or employees of embassies) should be worn by surgical masks on the face and wash their hands with soap. In 1971, the newspaper Izvestia acknowledged two waves of Hong Kong Influenza, hung on the Union in 1968 and 1970, and the preparation of Soviet doctors to the third: "Mass prophylaxis will be carried out by active immunization using a lively influenza vaccine." Due to the fact that the virus in the USSR has spread late, mortality was at the level of ordinary flu. According to virologists, the incidence rate did not exceed the average, the epidemic did not become large-scale: "It was impossible to silence about the problem, it was impossible to hide."

Winter died more

The virus resembled a living being: on each continent he acted in different ways. For example, in Asia and Africa, the second wave of H3N2 turned out to be for deadlines much more weaker, but in America and Europe killed infection in 2-5 (!) Times more. Specifically, the hit of "Hong Kong" made large countries start producing anti-happose vaccines: the epidemic also showed that the elderly people are in the risk area, and in France since 1984, the vaccination of pensioners began to be paid by the state. Peak death was noted in December 1968 - January 1969. You can again see similar things with COVID-19: the least suffer from the country, where the population does not differ in pofigism, but obstaciously observes hygiene and safety measures, taking into medical masks and not forgetting to wash your hands. Well, of course, the borders on the castle are helping: the later the virus penetrates into the state, the greater the chances of weakening. As a rule, a vaccine appears in 5-6 months. Another plus of Hong Kong influenza is the lack of panic and psychosis in the media. This also played a very significant role in the completion of the epidemic.
