Is it curable? Is it contagious and he will fit for work? What medication he needs? He is a smoker.Thanks.
[|AI|]  Thanks for your question on Chat Doctor. There are many causes for right upper lobe lesion.1. TB 2. Pneumonia3. Bronchiectasis etc. TB is very common in smokers due to poor lung defense.  So your husband may have TB. Better to consult pulmonologist and get done sputum examination and bronchoscopy and BAD analysis for TB. If he founds positiver than he should start Anti TB Chat Doctor. First 2 months H (isoniazid), R (rifampicin), Z (pyrazinamide), E (ethambutol) and next 4 months HR only. And yes during 1st moth he is infectious.
