SARS-CoV-2 infections among children and adolescents cause less severe illness and fewer deaths compared to adults. While a less severe course of infection is a positive outcome, there are concerns that mild symptoms may have led to less testing, resulting in fewer identified cases of COVID-19 in ch...ildren. If children with mild or no symptoms transmit the disease, they may act as drivers of transmission within their communities. Understanding symptoms, infectivity and patterns of SARS-CoV-2 transmission in children and adolescents is essential for developing, adapting and improving control measures for COVID-19 across all ages. This is a summary of the current knowledge around SARS-CoV-2 infection acquisition and transmission and COVID-19 disease symptoms in children and adolescents. It aims to inform decisions, based on local contexts, on how to best keep schools, kindergarten and day-care facilities open and what advice to apply to intergenerational mixing.

Preventing tuberculosis infection from progressing to tuberculosis disease is a crucial component of the goal to eliminate tuberculosis. When deciding on the use of tuberculosis preventive therapy among household contacts, policy makers regularly ask questions, such as whether tuberculosis preventiv...e therapy is effective, safe, and feasible in a programme setting and what it will cost. For contact management and tuberculosis preventive therapy for multidrug-resistant and rifampicin-resistant tuberculosis, studies from high-income and low-income countries have shown feasibility, safety, and effectiveness.
However, there is scarce information on the cost of tuberculosis preventive therapy for multidrug-resistant and rifampicin-resistant tuberculosis. In The Lancet Global Health, Peter Dodd and colleagues show that household contact management strategies are cost-effective even in low-income and middle-income countries, which has important policy implications for achieving the END TB Strategy goals.

Improving the management of childhood tuberculosis within national tuberculosis programmes: research priorities based on a literature review
WHO/HTM/TB/2007.381, 07.02
The disease burden caused by poor water, sanitation and hygiene is significant. For instance, soil transmitted helminthes (hookworm, roundworm, ringworm) infest approximately two billion people. Shistosomiasis infects and debilitates 200 million people. Trachoma, a disease related to poor sanitation... and hygiene which can cause blindness, infects five million people. However, the most serious health impact of poor WASH is diarrheal disease, particularly on children.
