This is the period immediately after the virus enters the body. At this stage, the virus multiplies quickly and transmission risks are highest.
This first phase can come with flu-like symptoms such as fever, throat pain, muscular pain, fatigue, swollen lymph-nodes and skin eruptions.
These symptoms, which disappear after a few weeks, are not present in all infected persons. Sometimes the primary infection stage goes by unnoticed. It is during this period that the immune system produces antibodies to defend itself against the virus.
