Topic: TB transmission & prevention
Tuberculosis (TB) bacteria can be transmitted when someone with active TB in their lungs coughs or sneezes. People whose immune system is keeping TB under control (latent TB) can take a course of medication known as isoniazid preventive therapy in order to reduce their risk of developing active TB disease. Research is ongoing into a vaccine that could be given to people with latent TB.
