is this available on sunday ,and what is the timing

Viral fever duration for most viral infections is 3-5 days , in few cases it may take 14 days

The disease can spread rapidly in areas with inadequate treatment of sewage and drinking water. The infection is not likely to spread directly from one person to another; therefore, casual contact with an infected person is not a risk factor for becoming ill.

Usully, fever is accompanied with increase in the body's temperature, weakness and body ache. Incase you feel any of these symptoms, you can take a Paracetamol. If the fever doesn't subside or keeps reoccuring, contact your doctor immediately.
