Healed pulmonary focus of T.B. If your friend has taken the Complete course of Anti Tuberculous Drugs and has Been declared disease free by pulmonologist/doctor via sputum negative test then He for sure Is Disease Free
BUT ths pulmonary focus of healed T.B Leison will remain there and it Only shows he once had T.b thats Now gone.. Only n only he can get T.b again if his Immune System Gets weak (due to any reasn like drugs or having HIV).. Otherwise Not.
why army rejectd him is their Own criteria.
one thing more sometimes bacteria become dormant(sleep) in this focus and may never cause T.b again and if the person gets immune Compromised the bacteria May wake up and cause Secondary T.b.
however to Knw that Bacteria is sleeping in this primary healed focus Is not Possible,so Some Countries and Organizatns Dnt Allow these People with Healed Leison.
