If you are sure it is small, you should pay attention, because the third and fourth days are the most dangerous periods. In severe cases, you may vomit blood or pull blood. It is also possible that both will appear, which will be more dangerous. What you can do now is:

Monoclonal antibody or immune serum intramuscular injection of antiviral intravenous energy: globulin, albumin, energy mixture, glucose, etc.
