Coronavirus: Mask refusers should be stigmatised like drink drivers, says scientist

PARIS (AFP) - People who refuse to wear face masks during the coronavirus pandemic should be stigmatised the same as drink drivers, the head of the prestigious Royal Society science journal said Tuesday (July 7).

The comments from Dr Venki Ramakrishnan come as two new peer-reviewed studies showed how wearing face coverings may help significantly reduce the spread of viruses such as Covid-19.

"It used to be quite normal to have quite a few drinks and drive home, and it also used to be normal to drive without seat belts," Dr Ramakrishnan wrote in a comment article. "Today both of those would be considered anti-social, and not wearing face coverings in public should be regarded in the same way."

Dr Ramakrishnan stressed how masks are only genuinely effective if worn by most people.

"If all of us wear one, we protect each other and thereby ourselves, reducing transmission," he said.

The Covid-19 pandemic has spread at different speeds throughout the world and there are a number of public health interventions that appear to have flattened the curve of localised new infections, including lockdowns and social distancing.

Estimates vary, but it is thought around 40-60 per cent of transmissions occur when carriers are pre- or asymptomatic - that is, they may not know they are ill but are still able to infect others.

One study by teams from the universities of Pennsylvania and Cambridge analysed pregnant women admitted for delivery in New York City who were screened for Covid-19.

They found that 13.7 per cent of the women were carrying the virus, 88 per cent of whom showed no symptoms.

Cloth face masks reduce oral particle dispersion between 50 and 100 per cent, depending on a number of factors, the researchers wrote.

In pre-symptomatic individuals, studies have shown that viral droplets are emitted not only by sneezing and coughing, but also by talking and breathing, meaning mass face coverings would significantly reduce the risk of new infections.

Another study published on Monday in the Royal Society outlined vast discrepancies in mask-wearing rates among rich nations.

In late April - as Covid-19 raged throughout Europe - mask-wearing uptake in Britain was around 25 per cent, the study found.

This compared with 83.4 per cent in Italy, 65.8 per cent in the United States and 63.8 per cent in Spain.

The authors said that while none of the countries studied had a culture of mask-wearing, those with established and clear public guidance had a far higher uptake.

"It isn't the public's fault for not wearing masks in the UK," said Professor Melinda Mills, director of the Leverhulme Centre for Demographic Science at the University of Oxford and lead author.

"Rather, consistent policies and effective public messaging is vital.

"People in countries like Italy, the US and Spain... have rapidly adopted face coverings largely because the authorities provided them with clear guidelines to understand why they should wear them."
