Khansi for 3 Weeks? When a Lingering Cough Needs a TB Test (Video)

Transcript

Cough That Won't Quit

If a cough lingers after a cold, it might be time to think about more than just a cold, especially when it stretches into weeks.

Cough Still Here

The cold may have passed, but the khansi stays for three weeks, troubling you at night while the household chalks it up to weather or excess phlegm. That's when doctors in Pakistan and India recommend a sputum test for TB, which is free at government centres and can protect your whole family.

At a Glance

In short, a cough lasting two to three weeks or more should prompt a TB check, especially if you also notice fever, sweats, loss of appetite, or blood in phlegm. The test is free and often paired with a chest X-ray.

Why Three Weeks

Most post-viral coughs clear within two to three weeks, but TB remains a possibility in South Asia. The rule exists because TB spreads through the air, and a single sputum test can confirm or rule it out quickly, helping to stop transmission before it spreads.

A test costs you a morning. Waiting can cost the family.

Beyond the Cough

TB can affect other parts of the body, like the spine, abdomen, or glands, sometimes without any cough at all. Keep an eye on low evening fevers, night sweats that soak your pillow, and weight loss without trying, as these may signal a deeper issue.

Testing Process

In government centres you’ll give a sputum sample, usually collected first thing in the morning before you eat or drink. Rinse your mouth with plain water, breathe deeply a few times, then cough hard from deep in the chest to bring up phlegm. The lab may ask for a second sample later in the day. Most places now use a rapid GeneXpert test that can detect TB and drug resistance within a day or two.

Screen Family

If someone tests positive, everyone sharing the home should be screened, even if they feel fine. Children under five, people with diabetes, HIV, kidney disease, or on steroids, as well as pregnant women and the elderly, need special attention. Keep rooms well ventilated and consider separate sleeping spaces during the early weeks of treatment.

Common Myths

A common myth is that TB spreads through dishes or handshakes; it actually spreads through the air when someone with lung TB coughs or talks. Another myth is that TB is a lifelong illness, it's curable with a full course of medication. Stopping early can lead to drug-resistant strains. Finally, TB doesn’t run in families like a genetic condition; anyone can contract it.

Traditional View

Unani and Ayurvedic texts describe a wasting illness with cough and fever, recommending rich foods, rest, and fresh air. Warm drinks, honey for adults, and mulethi (licorice) can comfort the throat, but mulethi raises blood pressure and isn’t suitable for people with heart, kidney disease, or pregnancy. These measures never replace proper testing and the full course of TB medicines.

When to See Doctor

Get tested after two to three weeks of coughing, sooner if you have fever, night sweats, or weight loss. Seek emergency care if you cough up blood, feel breathless at rest, have chest pain, or become confused. Pregnant women, people with diabetes or HIV, and children with cough plus weight loss need prompt assessment. Once on TB treatment, never skip doses and report any side effects like yellow eyes or rash to your doctor.
