LONDON (Reuters) - Keeping at least one metre apart and wearing face masks and eye protection are the best ways to cut the risk of COVID-19 infection, according to the largest review to date of studies on coronavirus disease transmission.

In a review that pooled evidence from 172 studies in 16 countries, researchers found frequent handwashing and good hygiene are also critical - though even all those measures combined can not give full protection.
