Hi, Thanks for posting in HCM. It is possible that you could have contacted with the influenza virus from your daughter but you remain fairly asymptomatic except for the presentation of cough. It is a viral infection, which is self limiting and would require only supportive management. Presently, since you do not have any other symptoms, kindly do the following to overcome the symptoms you are having. Take syrup containing Ambroxyl, Guaphenisin and Chlorpheniramine maleate as ingredients for cough. Do salt water gargling with warm water at least twice a day. You can also take chewable medicated lozenges to get relief of your throat and voice symptoms. Hope the information provided would be helpful. All the best.
