Extracts from this document...


Tuberculosis Symptoms of active tuberculosis * Persistent cough. * Chest pains. * Weight loss. * Coughing up blood or phlegm. * Shortness of breath. * Loss of appetite. * Weakness or fatigue. * Fever. * Night sweats. Tuberculosis is caused by a bacterium called Mycobacterium tuberculosis. It is spread by droplet infection. If someone who has Tuberculosis coughs then the infected droplets will stay in the air, if another person then breaths in the infected water droplets they will get Tuberculosis. There are two groups of people, who are considered to be at higher risk of developing TB than others they are, people with HIV and AIDS and people with Auto-immune illnesses (such as rheumatoid arthritis). ...read more.

In the first, people with TB and their contacts are identified and then treated. Identification of infections often involves testing high-risk groups for TB. In the second approach, children are vaccinated to protect them from TB (The vaccine is also known as the BCG). Unfortunately, no vaccine is available that provides reliable protection for adults. However, in tropical areas where the incidence of atypical mycobacterium is high, exposure to non-tuberculosis mycobacterium gives some protection against TB. ...read more.
