Influenza A H5N1/H1N1 – According to the report in November, Vietnam has about 400,000 cases of influenza. The main strains of the influenza virus are identified as Influenza A and Influenza B. The talk with Dr. Pham Cong Duc – Head of Department of Tropical Diseases at Bai Chay Hospital will provide identifying information about this type of influenza to readers.
What is Influenza A (H5N1/H1N1)?
Influenza A is an acute viral respiratory infection that is highly contagious and rapidly spreads in the community. There are 2 main causes of a high rate of influenza:
Because this time is winter-spring, the weather changes erratically hot, cold, and humid during the day, creating conditions for respiratory viruses to develop, including the influenza virus.
Also due to the erratic weather changes causing our resistance to decline, especially in children, the rate of infection with respiratory viruses increases, including influenza.
How is influenza A (H5N1/H1N1) spread?
Influenza A viruses can be spread easily from person to person in the same way that flu is spread through the air containing tiny droplets of water when an infected person coughs, sneezes, laughs, or talks. An infected person can also become infected with the influenza virus by touching contaminated objects, used tissues, and then touching their nose, mouth, or eyes. Sharing utensils, drinking glasses, or toothbrushes with sick people can also spread the influenza A virus.
Should I take Tamiflu when having the Flu?
Tamiflu is an antiviral, inhibiting the virus does not multiply, but does not have the effect of destroying the virus and needs to be used early within the first 2 days to have a significant effect.
Seasonal flu, like other respiratory viruses, usually clears up on its own, mainly with symptomatic treatment. People only use Tamiflu for serious cases that need to be seen by a doctor and prescribed by a doctor.
How to prevent influenza A?
To prevent influenza A, it is necessary to practice good personal hygiene such as washing hands frequently, wearing a mask when going out on the street, avoiding crowds, especially during an outbreak of flu, covering the mouth and nose when coughing or If you have a fever while sneezing, stay home for at least 24 hours after you stop to avoid infecting others.
If there are symptoms of high fever, cough, runny nose, headache, fatigue, the patient should rest and drink plenty of fluids. When these symptoms last long, they should not be subjective but should go to medical facilities for medical examination.
People identified with influenza A (H5N1/H1N1) by health facilities should rest, wear masks, and limit crowded places to avoid the virus spreading to surrounding people.
Also, the best way to prevent influenza A is to get a flu shot every year. Each flu shot can protect against 3-4 different flu viruses during that year’s flu season. High-risk subjects should be vaccinated with the annual influenza vaccine before the epidemic season, primarily the elderly and children aged 6 months to 5 years, especially 6 months to 2 years of age.
