Since you are suffering from a viral infection, you need to take proper rest so that your body is able to recover as soon as possible.
Drink plenty of water and other fluid.
Eat proper diet.
Take lots of high calorie food and carbohydrate
For the associated body pains, you might take some analgesics.
The more you rest, the less you will exhaust your body further and the earlier will you recover.
