Viewpoint on WHO implementation guidance on tuberculosis infection prevention and control

Extract Transmission continues to drive the tuberculosis (TB) and drug-resistant TB epidemics, making infection control an essential component for public health agencies worldwide [1–3]. Transmission of TB is complex, influenced by factors linked to patient behaviour, form of disease, the exposed individual, the microbe, and the environment [3–6]. Each year more than 10 million people develop TB, over 80% of whom have pulmonary disease and over 60% are bacteriologically positive [1].
