9 Things You Didn’t Know About Tuberculosis

World Tuberculosis Day is observed on March 24 every year to help spread awareness about the disease, communicate prevention measures as well as to commemorate efforts undertaken against the disease.

The date was earmarked due to the discovery of the Mycobacterium tuberculosis, a bacterium, which is the main cause of TB.

Although TB is a serious disease, it is curable. It can occur in almost every part of the body — the most commonly affected areas being lungs, lymph nodes, intestine, bone and brain. Early diagnosis is crucial for the treatment of TB. While Symptoms of TB include:

 

*Coughing that lasts for two or more weeks.

*Coughing up blood.

*Loss of appetite and unintentional weight loss.

*Fever, chills, night sweats and fatigue.

Here are nine things you should know about the disease.

 

  1. TB isn’t a disease of the past

Tuberculosis is still a very real danger, and in 2014, infected 9.6 million people across the world. Of these 9.6 million, 1.5 million people died as a result of the disease. This fatality rate is the same as that of diabetes, and even higher than that of stomach cancer.

  1. It’s an airborne disease

Tuberculosis is dangerous because of how infectious it is. It’s an airborne disease, meaning anybody could be infected by it in a very short space of time. For example, if an untreated sufferer has coughed or sneezed in a room you’re in, there’s a chance you could catch TB, too.

  1. Tuberculosis originated in cattle

It’s thought that tuberculosis was originally a disease that infected livestock. However, tuberculosis bacteria started to evolve, producing a separate strain that could infect people, too.

  1. Two billion are already infected with it

That’s one third of the world’s population. Almost 4,500 people die from tuberculosis every day, including 400 children. In fact, the World Health Organisation has named TB as second only to HIV and AIDS as the biggest killer worldwide.

  1. TB doesn’t only affect the lungs

While the lungs are the organ most commonly infected by tuberculosis, the disease can also occur in other parts of the body, including the bones, the urinary tract and the brain.

  1. It isn’t always easy to treat

Tuberculosis can take different forms, many of which are resistant to different types of antibiotics. Treatment for TB is for a minimum of 6 months to make sure all the bacteria are killed but drug resistant TB is even more difficult to treat and medicines may need to be taken for 18 months or more.

  1. Tuberculosis can lie dormant

Not everyone develops symptoms of TB as soon as they are infected. In some sufferers, TB won’t become active until weeks, or even months, later. In others, it can lie dormant for years. Those most at risk of developing active tuberculosis already have a damaged immune system.

  1. Prevention is key

Those with weak immune systems are at a much greater risk of contracting tuberculosis. Things like a poor diet, lack of sleep and stress can all have an impact, so ensuring that you take care of yourself will go a long way to building up your resistance to this kind of disease.

  1. Tuberculosis is a worldwide killer

More than 95 per cent of tuberculosis cases, and tuberculosis-related deaths occur in developing countries. Those most susceptible to catching the disease are people whose immune system is already weakened by suffering from HIV. In fact, HIV sufferers are 20 to 30 times more likely to develop TB.
