There are no medications currently available that can provide a cure. Treatment is aimed at providing support while the body fights off and eliminates the virus.
Supportive care may include:

- Hydrate—Drink plenty of beverages throughout the day. This will help to replace fluids, sugars, and salts lost during the illness. If you are unable to drink enough, you may need to receive intravenous fluids.
