Tuberculosis is a very dangerous bacterial infection which has affected about a quarter of the total population on earth and new infections affect 1 percent of the population every year. It is another highly contagious disease which affects the lungs. The average mortality rate of Tuberculosis is 12 to 15 percent. According to the statistics of the World Health Organization, in the year 2016, approximately 1 crore people fell ill due to tuberculosis and about 13 lakhs of them died in 2016. When compared with other deadly infections, tuberculosis is the second biggest human killer worldwide.
After this bacteria enters the human body by means of contamination through the air or by means of direct contact, it grows gradually in the part of the body having lots of blood and oxygen. According to statistics, less than ten percent of the people infected with this bacteria develop active Tuberculosis in their lifetime. If left untreated it can prove to be fatal.
