Tuberculosis, as an infectious disease, is second only to HIV-Aids as the world's greatest killer.
Every year in Malaysia, 22 000 people are diagnosed with tuberculosis.
Doctors working in a tuberculosis ward of Kota Kinabalu worry that after seeing a decline in cases in the 1990s, that trend has now sharply reversed.
They say the public needs to pay attention to the disease and take measures to prevent it.
