Our expert says:
“the 100 day cough” is another name for Whooping cough, which I am fairly sure you don’t have as you don’t describe the classic “whoop” and shortness of breath in your throat! We are also almost all vaccinated against whooping cough or pertussis ( ask your mom if you are not sure).
Many of the viruses that cause upper and lower breathing tract infections can cause irritation and inflammation that can take a while to go away, but especially in South Africa, if you have been coughing for more than 6 weeks you need an xray to exclude TB and your doctor need to check if you have a chronic post nasal drip or allergy that keeps feeding the cough.
