Malaysians flocking to vibrant Ramadan bazaars and communal breaking-of-fast events are being urged to observe strict TB precautions. The Health Ministry’s warning comes as the country grapples with over 3,000 reported cases, highlighting the risks posed by the massive gatherings and enclosed spaces typical of the holy month.
As many as 10 new clusters across seven states were reported in early 2026. According to Malaysian Health Minister Dzulkefly Ahmad, TB cases were detected in regions including Sabah, Selangor, Kuala Lumpur, Putrajaya, Kota Tinggi, and Johor.
Sabah recorded the highest number with 755 cases, followed by Selangor with 596 cases and Sarawak with 332 cases.
In a statement issued by the ministry, a total of 596 new TB cases were reported nationwide during the sixth epidemiological week.
Since the crowded, enclosed and poorly ventilated spaces increase the risk of transmission, the ministry has advised caution.
According to reports, the recent spike in cases is driven by delayed diagnosis, low treatment adherence leading to drug resistance, and lingering effects from the Covid-19 pandemic on health screening.
What is Tuberculosis?
Tuberculosis is an airborne bacterial infection that primarily affects the lungs. It spreads through the air when people with active disease cough, sneeze, or speak. Though the condition is serious, TB is preventable and treatable.
TB spreads easily where people gather in crowds. People with HIV/AIDS and other people with weakened immune systems have a higher risk of catching TB compared to others.
Symptoms of TB include: Cough, chest pain, fever, chills, night sweats, coughing up blood or mucus, pain while coughing, fatigue and lack of appetite.
There are different forms of TB, and one among them is the TB bacteria that have become drug-resistant. In this particular form, the medicines that once cured the disease will no longer work.
Why some TB bacteria become drug-resistant?
The bacteria become drug-resistant because of naturally occurring genetic changes. Random genetic mutations may grant certain bacteria the ability to resist antibiotics. These surviving cells can then multiply, leading to a population of increasingly resistant bacteria.
In the wake of the Chinese New Year and Ramadan, a significant number of travellers from Singapore are expected to visit Malaysia. However, health officials noted that risk levels vary: 'Unlike influenza or Covid-19, TB spreads more slowly and usually requires prolonged and repeated exposure,' the statement clarified.
To prevent transmission, the ministry has advised the public to maintain proper respiratory etiquette, ensure indoor spaces are well-ventilated, and wear masks in crowded settings or if feeling unwell. If you experience a persistent cough lasting over two weeks or other TB-related symptoms, please seek medical attention immediately.
