This is a lung infection caused by a certain type of bacteria. An infected
person with active TB spreads it through the air by breathing or coughing near
you. This is a very serious infection and it needs to be treated immediately.
It can ruin your lungs and affect many other organs in your body.
The initial symptoms are very mild and therefore they may go unnoticed. These
symptoms are a slight cough and a low-grade fever.
Many people may be exposed to TB sometime in their life, and it never develops
into the disease. These people are referred to as "carriers" and you
cannot catch TB from these people. Regular check ups are important to make sure
TB does not cause any damage.
