Malaysia's tuberculosis cases surge; citizens urged to exercise caution at Ramadan markets
Jakarta, CNBC Indonesia - Malaysia’s government has reported a surge in tuberculosis (TB) cases in early 2026. By the sixth epidemiological week of the year, 3,161 TB cases have been recorded nationwide, including 596 new infections during the latest monitoring period.
Through an official statement reported by Malay Mail, Malaysia’s Ministry of Health (MOH) has urged the public to remain vigilant, particularly amid increased social activities during Ramadan such as bazaars and communal breaking of the fast.
In detail, the state of Sabah reported the highest number with 755 cases, approximately 23.88% of the total. This was followed by Selangor with 596 cases (18.85%) and Sarawak with 332 cases (10.50%). Johor reported 280 cases, whilst the Federal Territories of Kuala Lumpur and Putrajaya recorded 244 cases.
However, authorities note that tuberculosis generally does not spread as rapidly as influenza or COVID-19. Transmission typically requires longer and repeated exposure.
“The risk of transmission increases when people are in closed, crowded indoor spaces with poor ventilation, particularly if there are individuals with active TB who have not yet commenced treatment,” the MOH stated.
Nonetheless, the level of risk depends on exposure duration, ventilation conditions, and individual immunity levels.
The Malaysian government has also emphasised that Ramadan is not a cause of TB transmission. However, increased social interaction during the month means the potential for contact between individuals is higher.
The public has been urged to practise proper coughing and sneezing etiquette, improve air circulation in indoor spaces, and wear masks if experiencing symptoms or in crowded places. For individuals with a cough lasting more than two weeks or related symptoms, immediate medical consultation is recommended.
“A community awareness-based approach is considered important to ensure early detection, effective treatment, and comprehensive prevention. Through collective action, Ramadan is expected to be observed safely and healthily,” the MOH said.
