Tuberculosis (TB): Symptoms, Free Testing and Treatment in Bangladesh
TB is common in Bangladesh but curable. Learn the symptoms, who is at higher risk, and how to get free government testing and treatment.
Tuberculosis (TB) is a serious infection that is common in Bangladesh. It is preventable and curable. According to the World Health Organization (WHO), Bangladesh’s National Tuberculosis Control Programme provides TB diagnosis and treatment free of charge to all citizens. This guide explains the symptoms of TB, how to get tested, which warning signs need urgent care and which doctor to see.
What is TB?
TB is caused by bacteria (germs). It most often affects the lungs, but it can also affect other parts of the body, including the kidneys, brain, spine and skin. Doctors call TB outside the lungs extrapulmonary TB.
TB spreads through the air when a person with TB in the lungs coughs, sneezes or spits. A person needs to breathe in only a few of these germs to become infected.
Not everyone who is infected becomes ill. WHO estimates that about a quarter of the world’s population has been infected with TB bacteria. Most of these people have TB infection. They do not feel sick and cannot spread it. According to WHO, about 5 to 10% of infected people eventually develop TB disease, which causes symptoms. Babies and children who are infected are at higher risk of developing the disease.
How common is TB in Bangladesh?
According to WHO’s Global Tuberculosis Report 2025, about 10.7 million people worldwide fell ill with TB in 2024. Bangladesh accounted for about 3.6% of them. That year, Bangladesh was one of eight countries that together had about two-thirds of the world’s TB cases. TB killed an estimated 1.23 million people worldwide in 2024. WHO says it is the world’s leading cause of death from a single infectious agent.
Who is at higher risk?
Anyone can get TB. According to WHO, the risk of TB disease is higher in people with:
- diabetes (high blood sugar)
- a weakened immune system, for example because of HIV
- undernutrition (not getting enough food or nutrients)
- tobacco use
- harmful use of alcohol
WHO advises people at higher risk to get checked for TB. This includes people with HIV and people in contact with someone who has TB at home or at work.
Symptoms of TB
TB symptoms may be mild for many months, so people can spread TB without knowing they have it. Common symptoms include:
- a cough that goes on for a long time, sometimes with mucus (phlegm) or blood
- fever
- night sweats
- losing weight without trying
- loss of appetite
- feeling weak or tired
- chest pain
- shortness of breath
WHO says that a cough that does not go away after two weeks is a cause for concern. You should see a doctor about it, and also if you have fever, night sweats or weight loss.
TB outside the lungs causes symptoms in the part of the body that is affected. According to the US Centers for Disease Control and Prevention (CDC), these can include blood in the urine (kidneys), back pain (spine), a hoarse voice (voice box), and headache or confusion (brain). Some people with TB disease have no symptoms but can still spread TB.
Free TB testing and treatment in Bangladesh
Bangladesh’s National Tuberculosis Control Programme (NTP) is led by the Ministry of Health and Family Welfare. WHO reports that the programme provides TB diagnosis and treatment free of charge to all citizens, including refugees.
If you have symptoms, go to a government health facility or see a doctor and ask to be tested for TB. The doctor will decide which tests you need. In Bangladesh, TB testing can include chest X-rays and molecular tests that detect TB germs. For example, WHO-supported mobile vans in Cox’s Bazar offer both.
What treatment involves
TB disease is treated with antibiotics (medicines that kill germs). It can be fatal without treatment. A doctor decides which medicines you need and for how long. Treatment lasts several months.
Some TB is drug-resistant. This means some of the usual TB medicines do not work against it, so it needs different treatment. The doctor and the TB programme will plan this.
Follow the treatment plan your doctor gives you until the end, and keep all follow-up appointments. If side effects, travel, work or money make it hard to continue, talk to your TB health worker or doctor straight away. Tell your doctor or health worker about any new symptoms during treatment and about any other medicines you take. Also tell them if you are pregnant or breastfeeding.
Protecting your family
- Cover your mouth and nose when you cough or sneeze, and do not spit in open places.
- Ask the health worker whether family members, especially children, should be checked for TB.
Warning signs that need urgent care
Get medical help straight away, at a hospital emergency department if needed, if you or someone you care for has:
- coughing up blood
- shortness of breath or chest pain
- headache or confusion
Headache or confusion can be a sign that TB has reached the brain (TB meningitis).
Which doctor should you see?
| Situation | Who to see |
|---|---|
| Cough lasting more than 2 weeks, or other TB symptoms, first check | Nearest government health facility, or a general practitioner or medicine specialist |
| TB in the lungs, drug-resistant TB or difficult cases | Chest disease specialist (pulmonologist or respiratory medicine doctor) |
| Children with possible TB | Paediatrician (child specialist) |
| TB with HIV or other complicated infections | Medicine or infectious disease specialist |
| TB of the spine, bones or joints | Orthopaedic surgeon, together with a medicine or chest specialist |
| TB affecting the brain or nerves | Neurologist, usually in hospital |
Whichever doctor you see, ask to be linked with the National TB Control Programme so that you get free diagnosis and treatment.
