How does flu virus attack humans?

Influenza virus floats in the air after being released from the patient's saliva. This virus is very popular with cold air and low humidity. From there, they become infectious.

Every year, during the flu season, an average of 20% of the US population gets this virus on average. Therefore, if you want to be one of those 20%, actively interact with as many sick people as possible!

People with a history of illness often incubate for a long time.

An adult can transmit the virus 1 day before and 3 to 7 days after symptoms appear. However, children can carry the disease for longer than adults. Even people who have been sneezed, runny nose, or those who have been infected but do not have any signs of going outside can still make the virus spread to others.

Most often, flu viruses float in the air after being released from the patient's saliva. This virus is very popular with cold air and low humidity. Under moist air conditions, droplets of water that carry the virus emitted from the patient's mouth will become heavier and fall to the ground - or on other surfaces. Therefore, the best way to avoid the flu virus is to move to the tropics. In these areas the flu season often does not exist because of the hot and humid climate.

According to the Harvard Medical School study, if you have the flu but don't want others to suffer for you, strictly follow these steps:

- The mouth and nose should be covered before coughing or sneezing.

- Throw used silk towels as soon as possible.

- Wash your hands often, especially after sneezing, coughing, or touching your eyes, nose and mouth.

- Keep a distance when interacting with other people, not embracing, kissing, or standing too close because tiny droplets can shoot to them and carry countless flu viruses.

- Disinfect household items regularly, especially the contact surface of children's toys.

Here are some tips to help you not get sick and spread the flu to those around you. However, frequent hand washing is still one of the best preventive measures for flu.
