My niece is having the problem of fever and she got rashes on her full body everyday and taken medicine also . paracetamol and cetirizine suspension .

Doctor can evaluate: Children's fevers are often from infections. Germs such as viruses and bacteria interact with the immune system, resulting in fever and sometimes a rash. Fevers may also occur from non-infection types of illnesses, but these illnesses are uncommon. A doctor can help find the cause of a fever and rash, to see if antibiotics or antivirals are needed to kill the germs, especially in younger kids.
