There is a possibility that the incubation period of influenza is 1 to 2 days, and it can be transferred to the surrounding people from one day before onset to around 5 to 7 days after onset.
Especially about 3 days from onset day is thought to be the most infectious power. Furthermore, even if the fever goes down, the influenza infectious power remains and there is a possibility of infecting other people.
(Although there are individual differences, there is a possibility that infection may occur for two days after the fever has fallen.)
Let’s wear a mask Influenza is infected by inhaling from the nasal cavity the virus released with a cough, sneezing, coughing, splashing like spinning. In order not to spread the influenza, it is effective that both the patient and the surrounding people wear masks.
When washing hands firmly again, touching the scattered influenza virus attachment with your hand may infect influenza via your nose, mouth, eyes, skin and so on.
That’s why hand washing is effective in preventing infection.
