On the same day, the National Health Commission held a press conference in Beijing to introduce the prevention and treatment of respiratory diseases in winter. Wang Dayan said that influenza viruses are prone to mutation, and professionals have been carrying out mutation monitoring. For the public, it only makes sense if there is a mutation of public health significance, and this has two aspects.
She said that on the one hand, the susceptibility of the virus to antiviral drugs, that is, whether the virus has drug resistance mutations. National influenza centers and laboratories around the world have been monitoring the susceptibility of influenza viruses to drugs used against influenza viruses. The surveillance results showed that the influenza virus is susceptible to several current anti-influenza virus drugs, that is, the anti-influenza virus drugs are effective against the influenza virus.
On the other hand, it is the compatibility of the circulating virus with the vaccine, that is, whether the virus has undergone antigenic changes. Wang Dayan said that compared with last winter, the composition of the influenza vaccine administered this winter has not changed from last winter, and the main influenza A (H3N2) subtype and B viruses that are now circulating have not changed, which is also consistent with the main branches circulating in most parts of the world.
Wang Dayan also suggested that influenza vaccination can effectively reduce the risk of infection, morbidity and severe disease. "It is recommended that high-risk groups, including the elderly, children and people working in public places, get an annual flu vaccine to strengthen their protection." (ENDS)
