Children ‘breathe out fewer aerosols’, which may reduce Covid risk – study

Primary-aged children produce about four times fewer particles than adults, which may help explain their lower transmission risk

Primary school-aged children produce about four times fewer aerosol particles when breathing, speaking or singing compared with adults, which could help explain why they seem to be at lower risk of spreading Covid.

Various studies have suggested that young children are about half as susceptible to catching Covid as adults, and, despite carrying a similar amount of virus in their noses and throats, appear to pass it to fewer people if they do become infected.
