Hi, welcome to Chat Doctor forum. Usually, we do a sputum AFB to rule out tuberculosis if cough persist more than 2-3 weeks. But, since she responded to treatment, and cough has come down, we can try a cough suppressant like dextromethorphan, and antihistamines for 5-7 days(I guess she has no fever/yellow sputum). It may help. If cough still persist, you please see your doctor and do sputum examination.Meanwhile, avoid dusty/cold environment. I hope you will find this information useful. Thank you.
