If you’ve been brushing off that lingering cough, it might be time to pay closer attention. Malaysia has already recorded 3,161 tuberculosis (TB) cases this year, and health experts warn the rise is linked to community spread in crowded spaces and poorly ventilated areas.

With Southeast Asia carrying one of the world’s heaviest TB burdens, spotting symptoms early and completing treatment is more important than ever.

Signs to Watch For

TB spreads through the air when infected people cough or speak. The bacteria can hang around for hours in enclosed spaces, which makes early detection crucial.

Common symptoms often get ignored: a cough lasting more than two to three weeks, low-grade afternoon fever, night sweats, unexplained weight loss, and persistent fatigue.

Many people mistake these for a cold or minor illness and rely on cough syrup instead of getting tested. That delay can put not only your health but also your family at risk.

Why a Persistent Cough Shouldn’t Be Ignored

Lim En Ni, Chief Pharmacist at Alpro Pharmacy, says prolonged coughing is often underestimated. “Even without a high fever, a cough lasting over two weeks should trigger a chest X-ray or sputum test,” she says. “Cough medicine only masks symptoms. Early screening improves treatment success and keeps your loved ones safe.”

High-risk groups include people with diabetes, smokers, anyone under chronic stress or lacking sleep, older adults, and anyone with weakened immunity.

TB Is Treatable — But You Must Finish Your Medication

The Ministry of Health emphasises that TB is curable, but treatment takes at least six months of consistent medication. Stopping early can lead to drug-resistant TB, making recovery harder and increasing public health risks. Lim adds, “Even during festive seasons or travel, never skip doses. Missing them fuels resistance.”

Everyday Steps to Stay TB-Free

From her pharmacy experience, Lim suggests practical ways to lower your risk of infection:

• Ventilate spaces every 2–3 hours – Open windows for at least 15 minutes, even with air-conditioning.
• Get sunlight and outdoor time – Direct sun exposure reduces TB bacteria survival.
• Don’t ignore a cough over two weeks – Avoid repeated usage of cough medicine; get screened
• Watch your blood sugar – Diabetics should monitor their diet, especially during festive seasons.
• Prioritise sleep – Chronic sleep deprivation weakens immunity.
• Wear a mask if you are experiencing cough
• Avoid sharing utensils, cups, or towels
• Get tested if exposed

If you notice symptoms or have concerns, talk to a doctor or pharmacist. Acting quickly protects both your health and your family’s.
