A new global study involving University of Queensland researchers has found more than half of adolescents are practising poor hand hygiene. UQ’s Institute for Social Science Research Doctor Yaqoot Fatima says that due to COVID-19 there is a renewed emphasis on adequate hand hygiene and results show that globally, adolescents practice poor hand hygiene. 354,422 adolescents aged 13 to 17 were examined by researchers who used data from the Global School-based Student Health Survey.
