According to the WHO director, what group of people should wear masks where social distancing cannot be maintained?

The recommendation from the World Health Organization (WHO) regarding mask-wearing pertains to individuals at higher risk of severe outcomes from COVID-19, particularly those aged 60 and older or those with underlying medical conditions. This guidance emphasizes the importance of protecting vulnerable populations who may face significant health risks if they contract the virus. Masks serve as an additional protective layer, especially in situations where social distancing is difficult to maintain, thereby helping to reduce transmission.

The focus on older individuals and those with pre-existing medical issues stems from research demonstrating their increased susceptibility to serious illness, complications, and mortality associated with the virus. Therefore, promoting mask use in these groups is a public health strategy aimed at safeguarding those most likely to suffer severe consequences, thereby also helping to reduce overall community spread.

In contrast, while children and healthcare workers have specific mask guidelines depending on circumstances, the broader public health messaging prioritizes the safety of high-risk populations. Furthermore, the recommendation for individuals living in crowded areas aligns with general public health practices regarding mask use but does not specifically target the most vulnerable demographic like the correct answer does.
