TB & Pulmonary

TB disease can be treated by taking medicine. It is very important that people who have TB disease are treated, finish the medicine, and take the drugs exactly as prescribed. If they stop taking the drugs too soon, they can become sick again; if they do not take the drugs correctly, the TB bacteria that are still alive may become resistant to those drugs. TB that is resistant to drugs is harder and more expensive to treat.

Other symptoms of TB disease may include:

  • Weakness or fatigue
  • Weight loss
  • No appetite
  • Chills
  • Fever
  • Sweating at night


At any time, staff or students with symptoms suggestive of TB including persistent cough over 3 to 4 weeks, blood in sputum, weight loss, afternoon fever, and night sweating should seek prompt medical consultation.

TB spreads mainly by air. It is essential to maintain good indoor ventilation by means of natural ventilation or mechanical ventilation such as exhaust fans. Furniture, tables, and walls do not play any significant role in the transmission of the infection. Regular cleaning of the environment should be done as general hygienic practice. The dust filtres of the air-conditioners should be cleansed as usual.
