Fighting tuberculosis

Mycobacterium tuberculosis, the bacteria that causes tuberculosis, was discovered on March 24, 1982, by Dr. Robert Koch. To date, Tuberculosis is the leading infectious disease in the world and a whopping 1.6 million people die from it every year. The greater risk of people likely to fall ill from the infection and spread it are people with compromised immune systems especially those living with HIV and those suffering adverse effects of malnutrition. This explains its prevalence in low-income countries.

Persons with Active TB exhibit symptoms such as persistent cough, night sweats, high fever, and weight loss. They can infect about 5 to 15 people through close contact within a year. The good news is that TB is curable and can be prevented by administering a TB vaccine.
