Prevalence of Multidrug-Resistant Tuberculosis (MDR TB)  and Its Challenges to Public Health in the World

Multidrug-resistant TB (MDR TB) is a type of tuberculosis that is caused by an organism that is resistant to the main drugs used for the treatment of TB. It is an air borne infection and mainly spreads through air. When a person suffering from TB coughs, sneezes, sings or speaks, bacteria are released into the air that remains in the air for a few hours. People who remain in such an environment gets infected and this is how the disease spread.

Cause of MDR TB

Resistance to anti-TB drugs can occur when these remedies are not used properly. It happens when patients do not take their drugs as prescribed by the physician or they fail to complete the treatment. It may also occur when the wrong medicines are prescribed by the physician in the wrong dosage and for an insufficient period of time. This kind of TB is most commonly seen in people who:

  • Develop recurrent attacks of TB after taking TB medicine in the past
  • Fail to get the proper treatment for TB in the past
  • Fail to take their medicine on time or on a regular basis
  • Spend considerable time with other people suffering from the same health problem
  • Live in the areas where most people suffer from this kind of infection

Prevention

The best way to prevent MDR TB is to take the prescribed medicines regularly and on time. The treatment should be continued for a specified period of time and each dose should be taken on time. One should avoid contact with people suffering from similar disease.
