Classification of Swine Flu

Influenza A, referred to as "A flu", is an acute respiratory infectious disease caused by influenza A virus infection, often occurs in winter, infectivity is strong, the population is generally susceptible.

Influenza is divided into four types: A, B, C and D. Influenza viruses that circulate seasonally in humans are influenza A (subtypes A H1N1 and A H3N2) and influenza B (Yamagata and Victoria) viruses.

Compared with influenza B virus, influenza A virus has a large number of hosts and is more likely to mutate or remix, resulting in large-scale transmission, and many large-scale outbreaks of influenza in history have been associated with influenza A virus.

Route of Transmission of Swine Flu

People with influenza and those who are invisibly infected (people who have been infected with the influenza virus but have not become ill) are the main sources of infection for seasonal influenza. Influenza is mainly spread by airborne droplets, but can also be spread by direct or indirect contact with mucous membranes such as the mouth, nose, and eyes.

Contact with items contaminated with the virus can also cause infection. In crowded and closed or poorly ventilated rooms, it can also be transmitted by aerosol.

How to Prevent
1. Take Good Personal Protection

Try to avoid going to places where people gather, avoid contact with people with respiratory symptoms, if necessary, you should take personal protection.

In case of respiratory symptoms, you should rest at home, health observation, do not go to work or go to class while sick; Try to avoid close contact with family members, if necessary, wear a mask; Cover your nose and mouth when sneezing or coughing to prevent the virus from spreading again.

2. Maintain Environmental Hygiene

Keep your home clean and ventilated, and regularly clean and disinfect key areas with frequent contact such as doorknobs and handrails.

3. Strengthen Health Surveillance

Health testing should be strengthened in crowded places such as schools, kindergartens and workplaces, and people should stay at home when influenza-like cases occur to reduce the spread of the disease.

4. Get Your Flu Shot ASAP

Influenza vaccination is one of the most effective ways to prevent influenza. Pregnant women, the elderly, patients with chronic diseases, young children and other high-risk groups are more likely to have serious complications after infection, and should be vaccinated as soon as possible when influenza vaccine is available.
