For a viral infection, treatment focuses on relieving symptoms. You can take Paracetamol (Acetaminophen) to reduce fever and ease throat pain. For your cough, an over-the-counter cough syrup (expectorant for a wet cough, or suppressant for a dry cough) can help. Warm salt water gargles and throat lozenges will soothe your throat. Rest well and drink plenty of fluids like warm water or tea. Please avoid taking antibiotics, as they do not work against viruses. If your fever remains high for more than three days or you experience difficulty breathing, please consult a doctor in person for a proper evaluation.
