Tuberculosis is one of the most severe infectious diseases which can be easily transmitted from one person to another. It can transmit from one to another in the form of droplets containing bacteria while one sneezes.  

Tuberculosis attended its peak in 1985 and many developed countries were seriously affected by this. However, the U.S. recovered with some strong control programmes by 1993 but it is still active in many regions.  

Tuberculosis is classified in two major categories depending upon the risk i.e. Latent TB and Active TB; similarly, symptoms vary. Latent TB doesn't show any symptoms, so it isn't easy to diagnose, while active  

TB's symptoms are: 

  • Bad appetite 
  • Chest pain and difficulty in breathing 
  • High fever 
  • Weight loss 
  • Coughing for more than usual (2-3weeks) 

An infected person generally spreads it in from of microdroplets that comes out he/she sneezes. It is contagious in nature, but you can still get affected with it if you are working or living with an infected individual. 


If you or anyone from family tests positive for TB, then maintain a proper distance from the infected person and do not share your personal accessories with others. If possible, quarantine the infected person or take him/her to the doctor.
