Students who have repeated a grade have higher risks of being victims of bullying in countries around the world, according to a new study of nearly half a million students.

New study results demonstrate that unstable housing and homelessness is associated with a two-fold greater chance of being re-infected with SARS-CoV-2 compared to those who are securely housed.
