Scientists say that it takes an average of five days for symptoms to appear when the virus enters the body, but in some cases it may take longer for some to appear.
The incubation period is the time when a virus is in the human body but there are no symptoms, the incubation period is up to 14 days in the case of Covid-19 - according to the World Health Organization.
But some researchers say that this period can be up to 24 days. That is, the germs can stay in your body for such a long time.
However, in the case of Bangladesh, the virus is believed to have a virus in the body of a person infected with Covid-19 for up to 21 days - said Mushtaq Hossain, an advisor and former chief scientific officer of IEDCR.
Mushtaq Hossain said, “The first day the coronavirus is detected in the body and if its symptoms go away within three to five days, it is assumed that he will not be able to infect anyone else after 21 days after the first day of the calculations from the first day.”
However, if the affected patient is only a patient with mild symptoms and his symptoms go away within three to five days, he will be considered safe after 21 days, he said.
