What is MDR and XDR TB?

MDR stands for Multi Drug Resistant TB

  • This is a most severe and difficult form of  TB to treat.
  • MDR often occurs when patients start treatment but don’t complete it and the infection returns stronger than the medicine initially given.
  • The germ becomes immune to the normal TB treatment
  • A person with the MDR spreads MDR- if you come into contact with the MDR germ, you will be infected with MDR TB even if you have never been treated for TB before
  • MDR takes eighteen to twenty four (18-24) months to treat

XDR stands for Extreme Drug Resistant TB

  • This often occurs when patients with MDR TB default from their MDR treatment and the MDR germ becomes stronger
  • than the medicine available to treat MDR
  • A person with XDR spreads XDR
  • There is currently no known cure for this form of TB
