Geneva – New World Health Organization (WHO) guidance will help countries accelerate efforts to stop people with tuberculosis (TB) infection becoming sick with TB by giving them preventive treatment.
A quarter of the world‘s population is estimated to be infected with TB bacteria. These people are neither sick nor contagious. However, they are at greater risk of developing TB disease, especially those with weakened immunity. Offering them TB preventive treatment will not only protect them from becoming sick but also cut down on the risk of transmission in the community.
