Although children and adolescents are less likely to suffer from severe disease and death from COVID-19, disruptions in critical health and nutrition services due to country response measures pose a significant threat to their servival, health and well-being. Countries have reported common reasons for these disruptions including shortages of health personnel, equipment and supplies; closures of facilities; reduced service hours; restrictions on transportation; financial difficulties making health care expenses prohibitive for many households; and fear of infection resulting in fewer families seeking health care services for their children and fewer pregnant women accessing maternal health services. UNICEF's latest survey tracking the impact of COVID-19 found that health-nutrition service disruptions were still widespread at the end of 2020. Over one third of 148 countries included in the survey reported reductions of at least 10 percent compared to the same time in 2019 in coverage of vaccination services, outpatient care for childhood infectious diseases, and maternal health services. About a quarter of these countries reported reductions of 10 percent or higher in vitamin A supplementation and treatment of child wasting. In addition, one in four countries with ongoing humanitarian situations was facing reductions of 10 percent or more in household drinking water services coverage, a major concern especially for countries with protected crises that are facing recurrent health outbreaks, such as cholera. Trade restrictions and disruptions in transportation due to the pandemic impact the food systems negatively, increasing the risk of food insecurity for millions of families. Widespread school closures have meant that millions of children and adolescents are missing out on nutritious meals and health services delivered through schools. An estimated additional 6.7 million children were expected to experience severe acute malnutrition or wasting by the end of 2020, increasing their risk of death and other negative health and development outcomes.
