If you have been coughing for a week without a fever and no contact with people returning from travel, it is best to stay at home and not worry too much. You can try using products like Sinus Rinse™ or drink plenty of water, rest, avoid irritating foods, and take cough syrup or warm honey to soothe your throat. If the cough persists after two weeks, it would be wise to see a doctor. Take care and rest up.
