Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain the symptoms that you son is experiencing of
fever and
cold sweats seems to be due to viral infection only and viral infection has no treatment to kill the virus..
The infection subsides after the virus completes its life cycle in individual's body who is infected..
Only supportive treatment to reduce temperature rise and other symptoms if present can help..
As of now you can give him
Acetaminophen to relieve fever and also do cool sponges over his body and extremities that is arms and legs..
Give him plenty of fluids to avoid
dehydration..
Give him ample of rest.
A soft bland diet should be given..
In case if the symptoms still does not resolve in another 3 to 4 days consult an Infectious Medicine Specialist and get evaluated..
Hope this information helps..
Thanks and regards.
