When is the contagious period of colds

Colds can be divided into wind-induced colds and viral colds. Severe wind-induced colds are generally caused by people catching a cold due to not wearing the right clothes, but viral colds are much more serious because they are highly contagious. Generally, when people catch a viral cold, they should not only recover quickly, but also try to isolate themselves from people around them. If viral influenza is contagious, when is it contagious?

How long is a viral cold contagious?

Viral colds, including influenza, are generally contagious for about 7 days. They can be transmitted from the end of the incubation period and are most contagious in the first 2 to 3 days of the disease. After the body temperature returns to normal, the virus is rarely present and the contagiousness decreases. However, there are often more latently infected people than sick people. They do not develop symptoms after infection and although they carry the virus for a short time, it is easy for them to spread the virus among the crowd.

The viral cold is contagious for a week. The cold will be completely cured after a week and the virus will disappear. If you take precautions, it will only take about a week and it will no longer be contagious after a week.

Colds often occur, but although they are a relatively common disease, they can also have a lot of impact on our health, so everyone must do a good job of prevention. If these colds occur, we must also pay attention to taking the most scientific and effective treatment methods to reduce the impact of these colds.
