This document provides information about multidrug-resistant tuberculosis (MDR-TB), including what it is, how it is treated, and how to prevent its spread. MDR-TB is a form of TB that is resistant to most common medications, making it more dangerous and difficult to treat than regular TB. The treatment for MDR-TB lasts 24-27 months and requires multiple medications under direct observation to be fully effective, though it can cause various side effects. Preventing the spread of MDR-TB requires properly taking medications, covering coughs and sneezes, improving ventilation, and limiting time with infected individuals.
