An updated Cochrane Review has suggested that ‘masks don’t reduce the spread of COVID in the community’. Does this finally put to bed the ongoing debate which continues to pit those who think masks are an aberration against the growing body of evidence showing benefit? Unfortunately not because, in simple terms, it isn’t good science.

Yet, even with the lessons from COVID-19, hygiene still struggles to gain political importance. Why? A lack of safe water, sanitation, and hygiene results not only in loss of dignity, safety, health, and education, but also economic potential. It is at the heart of “human capital,” not only for the current working generation, but for generations to come. However, the subject of hygiene has never been near the top of the political agenda, something that needs to change.

While influenza cases may have seen a decline over the past few years, hygiene experts are warning of a potential resurgence this winter. Too focussed on the fact COVID-19 may be becoming less of a threat, people could be caught off guard and spend the winter sicker than they may have been throughout the pandemic, they say.
