What is tuberculosis?
Tuberculosis (TB) is a potentially serious infectious disease caused by a particular bacterium. Prior to the Covid-19 pandemic, TB was the leading cause of infectious diseases-related deaths in the world. Most people infected with TB do not have symptoms and are not contagious in that stage. However, if the infection breaks out, it can cause health problems leading up to death. TB is spread through the air when an infected person coughs or sneezes. It usually takes being several hours in the same room in order to be infected. Typical symptoms include cough, fever, fatigue, weight loss and night sweats. If left untreated, the infection can lead to severe complications such as pneumonia, shortness of breath, lung bleeding, or even death. Treatment takes several months and is mostly only possible with a combination of different antibiotics.
