Symptoms of the disease

In a person who has been in contact with the virus, symptoms usually appear in the 14 to 16 days following contamination.

During a period of 5 or 6 days at most:

• slight fever;
• of the red pimples rashes, which look like insect bites, sometimes spread all over the body (even mucous membranes);

  pimples turn into small round blisters, filled with a clear liquid;

• of the itching.

After a few days, as they appear, the blisters dry out and form a crust. At this point, they are no longer contagious.
