Tuberculosis (TB)
Tuberculosis (TB) is a bacterial infection that’s spread via close contact with someone who has active TB. TB can affect your lungs or other parts of your body, and can be serious if not treated.
What is tuberculosis?
Tuberculosis (TB) is a bacterial infection that’s spread through inhaling tiny droplets from the coughs or sneezes of someone who has active TB.
In most people, despite inhaling the TB bacteria, their immune system controls it. This means the bacteria remain in the body in a dormant state, aren’t contagious, and never cause symptoms. This is called latent TB.
However, in about 5 to 10 out of every 100 people with latent TB, the bacteria can start to multiply or reactivate, which leads to symptoms. This is called active TB disease and can occur weeks, months, or years after you’re infected. Most often, it affects your lungs. But it can spread to other parts of your body, including your lymph glands, bones, gut, kidneys, or brain. The infection can be serious if it’s not treated.
At Welbeck, our respiratory physicians and radiologists at our custom-built Lung Health centre work together using the latest diagnostic medical technology to investigate and treat TB.
More information
The symptoms of active TB tend to come on gradually. They usually include:
a cough lasting more than 3 weeks
a loss of appetite
unexplained weight loss
a high temperature or fever
chills and/or night sweats
coughing up phlegm (mucus) or blood
fatigue
chest pain
Active TB that’s spread to your other organs may bring additional symptoms, including:
aches and pains in your body
swollen glands and/or joints
a headache
being sick
pain in your stomach or pelvis
constipation
cloudy or dark urine
a stiff neck
a rash on your face, legs, or another part of your body
If you have latent TB, you won’t have any symptoms. The only way to know if you have it is to take a TB test.
TB is caused by a slow-growing bacterium called Mycobacterium tuberculosis.
When someone with active TB coughs, sneezes, talks, or laughs, it can spread through the air and be breathed into your lungs. You would usually have to have a lot of contact with someone who has active TB to contract it.
You have a higher risk of developing active TB if:
you have HIV
you were born in a country of medium or high TB incidence, such as Latin America, the Caribbean, Africa, Asia, Eastern Europe, or Russia
you’ve lived in 1 of the above countries for over 3 months
you’ve had TB before
you have chronic kidney disease
you have type 2 diabetes
you have an alcohol or drug addiction
you’re taking a medication that suppresses your immune system, such as anti-rheumatoid agents or transplant rejection medication
At your initial consultation, one of our leading respiratory specialists will ask you to share your medical history and talk through your symptoms. They may need to conduct a physical examination and run further tests to make a diagnosis.
These tests may include:
a skin test
a blood test
imaging tests such as an X-ray or CT scan
phlegm tests
lung fluid tests
Your consultant will be able to recommend the most appropriate and effective treatment for you once they have an accurate diagnosis.
Preventive medication is available for some people with latent TB who have a higher risk of it developing into active TB.
If you have active TB, there are steps you can take to lower your risk of contracting and spreading the infection:
wash your hands properly and often
cover your mouth when you cough
cover your nose when you sneeze
avoid close and prolonged contact with others
Active TB shouldn’t cause any further complications if you get treatment and take it for the full length of time recommended by your consultant. However, it can be life-threatening if it goes untreated.
Treatment for active and latent TB usually includes a combination of antibiotics for at least 6 months. You may need to take the medication for up to 9 months.
After a few weeks of treatment, you might start to feel better, and your symptoms may appear to have reduced. It’s vital to keep taking your medication for the duration of your prescription; otherwise, the infection could return.

Frequently asked questions
If you receive treatment for TB so that you aren’t infectious, and you feel well enough to work, your employer can’t legally dismiss you.
No. COVID-19 and TB are different infectious diseases. However, they both affect the lungs, are spread through droplets in the air, and cause similar symptoms.
There had been progress towards a decline in TB cases over the last few decades. However, the most recent data from the UK Health Security Agency (UKHSA) found that TB cases rose by 13% between 2023 and 2024.
If you have TB, it’s best to avoid smoking and drinking excessive alcohol. Both of these can affect your lungs and immune system, and potentially make your TB symptoms worse.
