After infection, the virus gets itself situated, before beginning to grow very rapidly. Symptoms are most frequently a result of the immune response to the virus, rather than from the virus infection itself, and the immune system doesnt get into full stride and yield fevers until after this peak in virus transmission is achieved. She laughed. The virus presents itself differently in everyone and most individuals are infectious for a number of days before showing any symptoms (if ever). Once it hits its stride, in a single day the virus grows from hundreds of virus particles in the nose, to billions.
the tests are not definitive if always expensive.
