According to the Department of Preventive Medicine (Ministry of Health), influenza A/H1N1 is one of the causes of seasonal flu today.
At that time, the A/H1N1 influenza virus was first discovered, called a “pandemic” (pdm), meaning the appearance of a new type of flu.
According to the World Health Organization (WHO), seasonal flu spreads all over the world, with about 1 billion cases each year, of which 3-5 million are severe cases and 290,000-650,000 deaths.
In Vietnam, seasonal flu causes between 600,000 and 1 million cases each year.
In addition to influenza A/H1N1, other seasonal influenza strains including A/H3N2, influenza B, and influenza C also have a significant impact on public health.
Mechanism of spread and subjects at high risk
Influenza A/H1N1 is an acute infectious disease spread through small droplets when coughing, sneezing or direct contact with virus-infected objects.
Subjects at high risk of serious complications include:
– People with chronic diseases such as cardiovascular and respiratory diseases.
– The elderly, children, pregnant women.
– People with immunodeficiency.
The disease can cause severe pneumonia, multiple organ failure and even death if not treated immediately.
Recommended during changing seasons
The change of seasons is a favorable period for the development of respiratory diseases, including seasonal flu.
– Annual flu vaccination: This is the most effective measure to protect the body against the risk of infection.
– Maintain personal hygiene: Wash hands regularly with soap, avoid touching eyes, nose, and mouth.
– Wear a mask: Limit close contact with people with flu symptoms or other respiratory illnesses.
– Increase resistance: supplement a reasonable diet, get enough rest and exercise regularly.
Seasonal flu, although usually mild, can become a significant threat if not prevented and treated properly.
