Tuberculosis (TB) is often called a “silent disease” because it hides in plain sight. Its early signs can be so common — a cough, slight fever, or fatigue — that many people mistake them for a seasonal illness or ignore them altogether. But recognising TB symptoms early is the most powerful tool we have to stop the disease from spreading.
In India, TB continues to be a major public health challenge, with 2.42 million people diagnosed in 2022 under the National TB Elimination Programme (NTEP)¹. Early detection means early treatment — and that saves lives, reduces complications, and prevents further transmission in the community.

Quick Takeaways: Recognising TB Symptoms
TB spreads through the air when a person with active TB coughs, sneezes, or even talks. Just one untreated patient can infect 10–15 people in a year². Delayed diagnosis not only worsens the patient’s health but also fuels the cycle of transmission.
The World Health Organization (WHO) has consistently emphasised that early diagnosis and prompt treatment are the cornerstones of TB elimination³. Missing the warning signs often leads to advanced disease, severe lung damage, and sometimes, death.
The key symptoms of TB
While TB can affect different parts of the body, the lungs (pulmonary TB) are the most common site. The classic signs include:
- Persistent cough for two weeks or more (with or without sputum or blood).
- Fever, especially in the evenings.
- Unexplained weight loss.
- Night sweats.
- Fatigue and weakness.
The India TB Report 2023 highlights that cough was the most reported symptom among TB patients detected nationwide⁴. Unfortunately, many still delay visiting a doctor, either due to lack of awareness or stigma attached to the disease.
Red flags that need urgent attention
Not every cough means TB. But when accompanied by other symptoms, it is a signal not to be ignored. Seek medical help immediately if you notice:
- Coughing up blood (haemoptysis).
- Chest pain or difficulty breathing.
- Fever and night sweats lasting more than two weeks.
- Rapid, unexplained weight loss.
In rural and urban India alike, these symptoms are often first noticed at home. Recognising them early and seeking care through government health centres can make all the difference.

Overcoming barriers to early diagnosis
One of the biggest challenges in TB care is stigma. Many patients hesitate to disclose their symptoms or seek help, fearing discrimination. According to ICMR studies, stigma leads to delays in testing and treatment, especially among women and marginalised groups⁵.
The National Family Health Survey-5 (NFHS-5) also found that while awareness of TB has improved, misconceptions remain common in some states⁶.
India has made strong progress in building awareness through campaigns like “Ni-kshay Mitra” and expanding free diagnostic services under Ayushman Bharat Health and Wellness Centres¹. But awareness at the family and community level remains the true first line of defence.
What to do if you suspect TB
If you or someone you know shows symptoms of TB:
- Visit the nearest government health centre — free TB tests (sputum, X-ray, CB-NAAT) are widely available.
- Do not delay — early testing ensures early cure.
- Follow treatment completely — TB is curable, but only if medicines are taken for the full course.
- Protect others — cover your mouth when coughing and ensure good ventilation at home.
Listen to the Cough
Quick takeaways: Recognising TB symptoms A cough lasting more than 2 weeks is the most important warning sign. Fever, night sweats, and weight loss should never be ignored. Early diagnosis prevents spread to family and community. TB is curable with free treatment under NTEP. Timely medical help saves lives and lungs. |
A persistent cough can be more than just a minor issue – it might be your body’s warning sign. Recognizing the signs of TB can save your life, protect your loved ones, and help stop the spread of the disease in your community.
India is working towards eliminating TB, and to achieve this goal, we need to raise awareness about its symptoms. By speaking up and seeking help early, we can make a significant difference. The sooner we respond to the warning signs, the sooner we can stop TB.
As we continue our efforts to combat TB, let’s prioritize knowledge and action. By spotting the signs early and seeking help promptly, we can all contribute to a TB-free India.
