How to distinguish the flu from the common cold?

Influenza is an acute respiratory infectious disease caused by influenza virus, which can be divided into four types: A, B, C and D.

Among them, influenza A (H1N1 subtype and H3N2 subtype) and influenza B virus will cause seasonal epidemic every year, which is highly contagious.

The flu is not as simple as an "epidemic" cold. It comes more suddenly and has more serious symptoms. Take more precautions!

Vaccination against influenza is one of the most effective measures to prevent influenza, which can significantly reduce the risk of infection and improve the symptoms after infection.

Oseltamivir is an effective drug to treat influenza, but it is not a "magic drug". It is wrong to put oseltamivir in your mouth whenever you catch a cold.

As a neuraminidase inhibitor, oseltamivir is only effective against viruses with neuraminidase. At present, only influenza virus has such enzyme on its surface, while other viruses such as rhinovirus, respiratory syncytial virus and Covid-19 do not have such protein microdots on their surfaces.

Therefore, the symptoms of respiratory diseases, it is best to seek medical advice in time to confirm what virus is infected, and must follow the doctor’s advice. If oseltamivir is used blindly, it will only increase the burden of liver and kidney function.
