He said that a huge number (33 per cent) of TB patients remained undiagnosed, and they are the vector of the deadly disease.
The untraceable patients were the most vulnerable to transmitting the disease to others, he said.
Early diagnosis and prompt treatment is the best approach, but the patients do not visit health facilities before the situation much worsens, Nazis said.
