My father had a history of Asthma/ Bronchitis (chronic) due to smoking cigarette. However he has been treated well and living normal life with medication and inhaler's. My concern is whether my son who is 1 year old can get infected by any means from his grandfather? My son used to spend most of the time with his grandfather. I am very worried as my son is suffering from cough cold and throat infection from last few days. Kindly advice whether it is communicable to grandson.
