Tuberculosis (TB): Symptoms, Tests and Free Treatment

Quick answer

Tuberculosis is a bacterial infection — caused by Mycobacterium tuberculosis — that most often attacks the lungs but can affect almost any organ. It spreads through the air when a person with active lung TB coughs or sneezes. Pakistan carries one of the world's heaviest TB burdens: WHO data shows over 669,000 people affected, about 1,800 new cases every day, and 140 deaths every day — making Pakistan the 5th most affected country in the world and bearing 73% of the TB burden in the Eastern Mediterranean Region. Yet TB is curable — and in Pakistan, diagnosis and treatment are free at thousands of government and partner facilities.

What does it mean?

Tuberculosis is a bacterial infection — caused by Mycobacterium tuberculosis — that most often attacks the lungs but can affect almost any organ. It spreads through the air when a person with active lung TB coughs or sneezes. Pakistan carries one of the world's heaviest TB burdens: WHO data shows over 669,000 people affected, about 1,800 new cases every day, and 140 deaths every day — making Pakistan the 5th most affected country in the world and bearing 73% of the TB burden in the Eastern Mediterranean Region. Yet TB is curable — and in Pakistan, diagnosis and treatment are free at thousands of government and partner facilities. The tragedy is not that TB can't be treated; it's that too many people are diagnosed too late.

Common causes

  • 1The hallmark symptom is a persistent cough.
    Pakistan's national TB guidelines state the most common symptom is a productive cough lasting more than 2 weeks, which may come with other symptoms.
  • 2Other warning signs:
    unexplained weight loss, night sweats, persistent low-grade fever (especially in the evenings), chest pain, coughing up blood, tiredness and loss of appetite. Anyone with a cough beyond two weeks plus any of these should be tested for TB promptly .
  • 3It spreads through the air — but only from active lung TB.
    Tiny droplets from coughing or sneezing can hang in the air; close, prolonged contact raises risk. People with latent TB infection (bacteria present but inactive) cannot spread it and feel no symptoms — though it can activate later, especially with weak immunity.
  • 4Diagnosis is straightforward:
    sputum (phlegm) tests — at least two sputum samples examined in a quality-assured lab — plus chest X-ray and newer rapid molecular tests where available. Around 1,500 laboratories nationwide provide free diagnostic services (Provincial TB Control Program).
  • 5Standard treatment cures most TB in 6 months:
    an initial 2-month intensive phase with four medicines, followed by a 4-month continuation phase with two medicines, taken daily under observation (the DOTS strategy). Fixed-dose combination tablets are preferred.
  • 6Treatment is FREE.
    Provincial TB programs confirm free treatment for all TB patients at public facilities — over 2,000 public and private facilities offer free diagnosis and treatment across Pakistan (WHO via Dawn). The program also covers drug-resistant TB management and preventive therapy for high-risk groups.
  • 7Drug-resistant TB (MDR/XDR) is a growing threat.
    It develops mainly when treatment is taken irregularly or stopped early — which is why completing the full course, even after you feel better, is the most important rule of TB treatment.
  • 8BCG vaccine
    is given at birth in Pakistan's immunization program; it protects young children against severe forms of TB but does not fully prevent lung TB in adults.
  • 9Newer 4-month treatment regimens

    Alongside the standard 6-month course, newer 4-month regimens are now available for eligible patients:
  • 11Adults and adolescents (12 years and older, weighing 40 kg or more):
    an intensive phase of 8 weeks (2 months) with isoniazid, rifapentine, pyrazinamide and moxifloxacin (2HPMZ), followed by a continuation phase of 9 weeks (about 2 months) with isoniazid, rifapentine and moxifloxacin (2HPM). This regimen is for drug-susceptible pulmonary TB, and includes certain stable HIV-positive patients and people with diabetes. It is not for pregnant or breastfeeding women, children under 12, anyone weighing under 40 kg, severe extrapulmonary (outside-the-lungs) TB, or advanced HIV (CD4 below 100 cells/mm³).
  • 12Children (3 months to 16 years) with non-severe pulmonary TB:
    an intensive phase of 2 months with isoniazid, rifampin, pyrazinamide and ethambutol, followed by a continuation phase of 2 months with isoniazid and rifampin. Your TB centre will decide which regimen fits you — whichever course you are given, completing it fully is what cures TB and prevents drug resistance.

Prevention & practical tips

  • ✓Get tested early. If you or a family member has had a cough for more than 2 weeks — especially with weight loss, night sweats or fever — visit the nearest government hospital, Basic Health Unit or TB center. Testing is free.
  • ✓Complete the FULL treatment course. Take every dose, for the full duration (usually 6 months), exactly as the TB center instructs — even when you start feeling better after a few weeks. Stopping early breeds drug-resistant TB.
  • ✓Protect others while infectious: cover your mouth and nose when coughing or sneezing, dispose of tissues safely, keep rooms well-ventilated with fresh air and sunlight, and sleep separately if advised until your doctor says you are no longer infectious (usually after a few weeks of proper treatment).
  • ✓Get household contacts screened. Family members living with a TB patient are at higher risk and should be tested — children under 5 and people with weak immunity may need preventive treatment.
  • ✓Support, don't isolate. TB patients need encouragement to finish treatment — stigma keeps people from seeking care and costs lives. TB is curable; a patient on proper treatment quickly becomes non-infectious.
  • ✓Eat well and avoid tobacco and alcohol during treatment — good nutrition and a healthy immune system help the medicines work.

FAQs

What are the early symptoms of TB?

A cough lasting more than 2 weeks is the classic early sign, often with weight loss, night sweats, evening fever, tiredness and loss of appetite. Coughing up blood can occur in later stages.

Is TB treatment really free in Pakistan?

Yes. Diagnosis and treatment are free at government TB centers, Basic Health Units and thousands of partner facilities — over 2,000 facilities nationwide, per WHO. Treatment for drug-resistant TB is also provided through the national program.

How long does TB treatment take?

Standard drug-sensitive TB is treated for 6 months (2 months intensive + 4 months continuation). Drug-resistant TB needs longer, specialized regimens — decided by TB specialists.

Can TB spread by sharing food or touching?

No. TB spreads through the air via coughs and sneezes from someone with active lung TB — not through food, water, utensils, handshakes or touching. Latent TB (inactive infection) does not spread at all.

ٹی بی کی علامات کیا ہیں اور علاج کہاں سے مفت ملتا ہے؟ (tb ki alamat kya hain aur ilaj kahan se muft milta hai?)

ٹی بی کی سب سے عام علامت دو ہفتے سے زیادہ کھانسی ہے، جس کے ساتھ وزن کم ہونا، رات کو پسینہ آنا، شام کو ہلکا بخار، تھکاوٹ اور بھوک نہ لگنا ہو سکتا ہے۔ خون کی کھانسی بھی ہو سکتی ہے۔ پاکستان میں ٹی بی کا ٹیسٹ اور علاج بالکل مفت ہے — قریبی سرکاری ہسپتال، بنیادی مرکز صحت یا ٹی بی سینٹر جائیں۔ علاج عموماً 6 ماہ چلتا ہے اور مکمل کرنا لازم ہے — چند ہفتوں میں بہتر محسوس ہونے پر دوا بند نہ کریں ورنہ دوا سے مزاحم ٹی بی (MDR) ہو سکتی ہے۔ مریض کے گھر والوں کا بھی ٹیسٹ ہونا چاہیے۔ کھانستے وقت منہ ڈھانپیں اور کمرے ہوادار رکھیں۔
