When do infected people transmit the virus?
With or without symptoms, infected people can be contagious and the virus can spread from them to other people.
When Do Infected Persons Transmit the Virus?
Lab data show that infected people are most contagious just before they develop symptoms (i.e. 2 days before they develop symptoms) and in the early stages of their illness. People who develop severe illness may be contagious for a longer period.
While a person who never develops symptoms can transmit the virus to others, it is still unclear how often this occurs and more research is needed in this area.
You can use the Foaming Test Kit to prevent this situation. The Foaming Test Kit gives results in 15 seconds and shows whether the virus is in your body or not, precisely and painlessly.
