World TB Day: Finding new ways to test children for tuberculosis
24 March 2021
Every year, over a million children fall ill with tuberculosis (TB) globally, and about a quarter die from this potentially preventable and curable disease. The main challenge remains the diagnosis of TB, especially in resource-constrained settings. We currently need to collect mucus from the lungs or liquid contents of the stomach, which must be collected in a hospital. Different ways to diagnosis TB in children are urgently needed, especially for those infected with HIV. An international collaboration is now conducting a large diagnostic study in Uganda to fill this gap. The study aims to detect TB bacteria in body fluids such as blood, urine, stool and saliva that are easier to collect.
