TB is a communicable chronic disease that every year affects 10 million people and kills almost two million people in the world.
Medical experts aver that people infected with TB bacteria have a 5-15 per cent lifetime risk of falling ill.
When a person develops active TB disease, the symptoms (such as cough, fever, night sweats, or weight loss) may be mild for many months.
People with active TB can infect 5-15 other people through close contact over the course of a year.
Without proper treatment, 45 per cent of HIV-negative people with TB on average and nearly all HIV-positive people with TB will die WHO said.
On symptoms and diagnosis of TB, WHO identifies common symptoms of active lung TB to include cough with sputum and blood at times, chest pains, weakness, weight loss, fever and night sweats.
People living with HIV are 20 to 30 times more likely to develop active TB disease than people without HIV.
To address the risk for TB transmission to uninfected persons, the World body recommends implementation and scale-up of TB infection control measures, including managerial (leadership and commitment for establishing and implementing infection control policies at the health facility), administrative (prompt identification and separation of persons with presumptive TB, with timely diagnosis and treatment of TB patients), and environmental (optimization of building design and patient flow to reduce the concentration of TB droplet nuclei in the air and control directional flow of potentially infectious aerosols) measures and personal protective equipment (PPE) use, implemented in conjunction with other infection control measures, to reduce the risk for TB transmission in health care facilities.
