The land with no face masks: Holland’s top scientists say there’s no solid evidence coverings work and warn they could even damage the fight against Covid-19

‘Face masks in public places are not necessary, based on all the current evidence,’ said Coen Berends, spokesman for the National Institute for Public Health and the Environment. ‘There is no benefit and there may even be negative impact.’

This is a bold but highly controversial stance – especially as fears grow of a second wave sweeping through Europe. Last week, Downing Street joined the global stampede to enforce face masks in public spaces such as shops, supermarkets and stations, following Scotland, Spain and France, along with Holland’s neighbouring nations of Belgium and Germany.

Holland’s position is based on assessments by the Outbreak Management Team, a group of experts advising the government. It first ruled against masks in May and has re-evaluated the evidence several times, including again last week.

It believes they detract from a clear three-pronged message that has kept deaths from coronavirus down to less than half the rate in Britain: wash hands regularly, maintain social distancing of 1.5 metres and stay at home if suffering any symptoms.

The one exception outside of the medical frontline has been on public transport, where masks are mandatory on the basis it is difficult to stay apart on crowded buses, ferries and trains. ‘We have seen this approach works,’ said Christian Hoebe, a professor of infectious diseases in Maastricht and member of the advisory team. ‘Face masks should not be seen as a magic bullet that halts the spread.
