The symptoms of flu that are usually felt by the sufferer are fever, headaches, coughs, aches, loss of appetite, and sore throat. Flu symptoms will get worse for 2-4 days before finally getting better and cured.

Flu and colds are two different conditions. Colds generally appear gradually with lighter symptoms, so it does not affect the routine of the sufferer. While the flu is not like that, this disease tends to cause more severe symptoms, so that it can interfere with the activity of the sufferer. In addition, the flu incubation period is also shorter.

Influenza virus spreads through the air in droplets or splashes (droplets) when someone infected with coughing, sneezing, or talking. You can inhale the drops directly, or get a virus when holding certain objects, and then touch the eyes, nose, or mouth.

People who are infected with viruses are likely to transmit the virus since about one day before the symptoms appear, up to about five days after the symptoms appear. Children and people with a weak immune system may transmit it in a little longer time.

Influenza virus continues to mutate, with a new type that appears regularly. If you have experienced influenza before, the body has made antibodies to fight certain types of influenza viruses. If future influenza viruses are similar to what you met before (either with disease or vaccination), antibodies can prevent infection or reduce the severity of symptoms. However, the level of antibodies can decrease over time.

Although the flu can attack everyone, but there are some people who are quite vulnerable to the flu virus. For example:

Pregnant or new birth.
Toddlers and elderly.
With certain medical conditions, such as diabetes, asthma, heart disease, or obesity.
