Tuberculosis (TB) is a bacterial infection that usually affects the lungs. According to the World Health Organization's Global Tuberculosis Report 2025, the Philippines has the third-highest number of TB cases in the world, at about 6.8% of the global total. The good news is that TB is curable, and in the Philippines testing and medicines are available for free through the government's TB program.
Common Symptoms of TB
- A cough lasting 2 weeks or more, with or without phlegm
- Coughing up blood or blood-streaked phlegm
- Fever, often in the afternoon or evening
- Night sweats
- Unexplained weight loss and loss of appetite
- Chest pain and unusual tiredness
Some people have only mild symptoms at first, so a lingering cough should not be dismissed as just a smoker's cough or an allergy. TB can also affect other parts of the body, such as the lymph nodes, bones, and spine.
In children, watch for a long-lasting cough, poor weight gain, fever, and low energy. Children who live with someone who has TB should be checked even if they look well.
How TB Spreads, and How It Doesn't
TB spreads through the air when a person with active TB in the lungs coughs, sneezes, or talks. It usually takes repeated close contact, which is why people in the same household are most at risk. You do not get TB from sharing plates and utensils, shaking hands, or touching clothes.
Who Is at Higher Risk?
- People living with someone who has active TB
- People with diabetes or HIV
- Smokers and heavy drinkers
- People who are undernourished
- Young children and seniors
- People in crowded housing or workplaces
Where to Get Tested and Treated for Free
TB care in the Philippines runs through the National TB Program, using an approach called TB-DOTS. You can go to your barangay health center, rural health unit, or a DOTS-accredited hospital or clinic. Staff will usually arrange:
- A sputum test, often a rapid molecular test such as GeneXpert
- A chest X-ray
- Free anti-TB medicines and regular monitoring if you are diagnosed
PhilHealth also has an outpatient TB-DOTS package that can be used at accredited TB-DOTS centers. It covers drug-susceptible TB, and does not cover hospital admissions or drug-resistant TB. Ask the facility what applies to you. For more on benefits, read our PhilHealth coverage guide.
How Long Does Treatment Take?
Regular TB is usually treated with a combination of medicines for at least 6 months. Most people feel better within a few weeks, but you must finish the full course even after the cough is gone. Stopping early can bring TB back and can lead to drug-resistant TB, which is much harder to treat and takes longer.
Tell your health worker right away if you notice yellow eyes or skin, dark urine, severe nausea or vomiting, a rash, or changes in your vision. Do not stop or change your medicines on your own.
A Spot on Your Chest X-Ray at Work: What Now?
Many Filipinos first hear about TB after a pre-employment or annual physical exam, or a medical for working abroad. An abnormal X-ray is not automatically active TB. It could be:
- An old scar from a past infection that is no longer active
- Active TB, which needs treatment
- Another lung condition, such as pneumonia
The usual next step is to see a doctor for sputum testing and a clinical assessment. Bring your X-ray film or report, and ask for a written medical clearance if your employer needs one. Rules for overseas work differ by country and agency, so ask your clinic or agency what proof is required.
What Is Latent TB?
Some people carry TB bacteria without being sick. This is called latent TB. It causes no symptoms and is not contagious, but it can become active later. Doctors may recommend preventive treatment for people at higher risk, such as household contacts and people with weakened immune systems.
When to Go to the ER
Go to the nearest emergency room if you cough up a large amount of blood, have severe difficulty breathing, or have severe chest pain.
Which Doctor Should You See?
Your local health center is a good first stop. For a private consultation, a pulmonologist or internist can evaluate a long-lasting cough or an abnormal X-ray, and a pediatrician should check any child with possible TB.
