Frequently Asked Questions to Prevent Influenza A H1N1
[Release:] [2009-5-14] [Close]

1. What is H1N1 influenza?

H1N1 influenza virus (formerly known as human infection with swine influenza virus) is a new influenza virus. This new virus was first detected in humans in the United States in April 2009. As of May 11, 2009, the World Health Organization announced that 29 countries and regions, including Mexico, the United States, and Canada, have reported laboratory-confirmed cases of H1N1 influenza. The virus can be transmitted from person to person and is very similar to how seasonal influenza viruses are transmitted.
2. Why is the "swine flu virus" renamed to H1N1 influenza virus?
The virus was originally named the swine flu virus because initial laboratory tests showed that some of the genes of the new virus are very similar to the flu viruses that often occur in pigs in North America. However, further research has shown that the new virus is different from the influenza virus that is commonly transmitted by pigs in North America. The virus has two gene fragments derived from pig, bird and human genes in Asia and Europe. The World Health Organization announced on April 30 that the virus was named "A H1N1 influenza virus", and that the Ministry of Health of China on April 30 named the disease "H1N1 influenza A".
3. Do I have H1N1 patients in China?
On May 11, 2009, the first case of H1N1 influenza was confirmed in Sichuan Province, China.
4. What are the symptoms of H1N1 influenza patients?
Symptoms of a person with H1N1 flu are very similar to those of the general flu, and generally include fever, cough, sore throat, runny nose or stuffy nose, generalized pain, headache, chills and fatigue. Some people can also show diarrhea and vomiting. Similarly, patients with influenza A (H1N1) can experience severe cases or deaths just like seasonal influenza patients.
5. How infectious is H1N1 influenza?
The H1N1 influenza virus can spread from person to person and the population is generally susceptible to infection. The H1N1 flu is contagious and spreads very similarly to seasonal flu, and is contagious from 1 day before the onset of symptoms to 7 days after the onset of symptoms. Some people do not show symptoms after being infected with the virus, but they can pass the virus on to others in a state of being infected.
6. How is influenza A H1N1 transmitted?
At present, the transmission of this H1N1 virus is considered to be very similar to that of seasonal influenza. Influenza viruses are mainly transmitted to others by coughing or sneezing in people with H1N1 flu or a person with a recessive infection. People can also get infected by touching flu-contaminated objects and then touching their nose, mouth or eyes.
The incubation period of H1N1 influenza has not yet been determined, and the reference seasonal influenza is generally 1 to 7 days.
7. How to do personal protection?
◆ Try to maintain good physical health, ensure adequate sleep, maintain a good mental state, drink enough fluids and eat nutritious food.
◆ Avoid close contact with patients with flu-like symptoms (fever, cough, runny nose, etc.).
◆ Avoid going to crowded places or minimize the time spent in crowded places.
◆ When coughing or sneezing, cover your nose and mouth with a paper towel and throw it into the trash.
◆ Wash your hands with soap and running water, especially after coughing or sneezing. Alcohol-based hand sanitizers are equally effective.
◆ Avoid touching your eyes, nose and mouth.
8. Is there a H1N1 influenza vaccine?
There is currently no vaccine against H1N1 influenza. According to the risk assessment of the epidemic, the World Health Organization and national experts will comprehensively consider matters related to the development, production and use of the epidemic.
9. Is it safe to eat pork and pig products?
The World Health Organization has suggested that there is no evidence that the H1N1 virus can be transmitted to humans by eating properly processed pork or other pig products. Pork and other meats can be eaten after they are cooked and cooked.
10. Are there any medicines for the treatment of H1N1 influenza?
US studies have shown that Tamiflu (also known as oseltamivir) has an inhibitory effect on the H1N1 influenza virus. Zanamivir also has a significant inhibitory effect on the H1N1 influenza virus. The medication should be taken under the guidance of a doctor.
11. What is the best way to wash my hands?
It is recommended to wash your hands with soap and running water, or rub your hands with an alcohol-based hand sanitizer.
12. How can patients with influenza A H1N1 flu avoid coughing or sneezing to spread to others?
If you may be infected with the H1N1 virus, you should avoid close contact with other people as much as possible. Do not go to work or school until 7 days after the illness or 24 hours after the symptoms disappear (whichever is longer). When you cough or sneeze, you should cover it with a paper towel and throw it in a trash can to prevent people around you from becoming infected. If you don't have a paper towel, you can cover it with your hands and then wash. Be sure to do it every time.
13. What methods can kill this virus?
Influenza viruses can be killed by heating at 75 to 100 C. In addition, some chemical fungicides, such as chlorine, hydrogen peroxide, iodine, and alcohol, can effectively kill human influenza viruses. When disinfecting, care should be taken to use the appropriate concentration and sufficient time.
