  • Which kind of face mask will best protect you against coronavirus?
  • Does it matter what sort of mask you wear? Yes. Different types of mask offer different levels of protection. Surgical grade N95 respirators offer the highest level of protection against Covid-19 infection, followed by surgical grade masks. However, these masks are costly, in limited supply, contribute to landfill waste and are uncomfortable to wear for long periods. So even countries that have required the public to wear face masks have generally suggested such masks should be reserved for health workers or those at particularly high risk.
  • but still suggests that face masks can contribute to reducing transmission of Covid-19. Analysis by the Royal Society said this included homemade cloth face masks.

  • Are paper surgical single-use masks better or is a cloth mask OK? The evidence on any mask use, outside of surgical masks, is still emerging: there appears to be some benefit, but the exact parameters of which masks are the best and the extent to which they protect the wearer or those around them are still being figured out. A tighter fitting around the face is probably better, but the CDC suggests any covering, including a bandana, is better than none.
  • heavyweight “quilter’s cotton” or multiple layers of material. Scarves and bandana material were less effective, but still captured a fraction of particles.
  • Replace the mask when it is damp. To remove your mask, take it off using the elastic tags, without touching the front and discard immediately into a closed bin or, if the mask is reusable, directly into the washing machine.
  • How often do you need to wash masks? They should be washed after each use. The US Center for Disease Control suggests “routinely”.
  • if every person in the UK used one single-use mask each day for a year, an extra 66,000 tonnes of contaminated plastic waste would be created. The use of reusable masks by the general population would significantly reduce plastic waste and the climate change impact of any policy requirements for the wearing of face masks, according to the UCL team, led by Prof Mark Miodownik. They say that according to the best evidence, reusable masks perform most of the tasks of single-use masks without the associated waste stream.

Anger over Prince Charles's Covid-19 test is a warning sign of divisions to come | Gaby... - 0 views

  • We are all still in this together. But some of us are now falling so much deeper into it than others.
  • No wonder some were furious, then, when it emerged that Prince Charles had been tested despite suffering from what’s said to be only a mild case of coronavirus. Buckingham Palace insists it was done for sound clinical reasons, and even if it wasn’t, one princely test makes no practical difference to the ability of hundreds of thousands of key workers to get one.
  • Houses that normally sit shuttered and forlorn until Easter started opening up again the minute the schools shut – and so many people have been trying to book hideaway cottages on remote Scottish islands that ferry crossings are being restricted. Tiny communities with no cases of their own are understandably afraid of what wealthy urban refugees may bring with them, and fear curdles all too easily into resentment.

  • The safety net knitted last week at breakneck speed, meanwhile, is already starting to fray at the edges. Renters worry that their three-month reprieve from eviction might not be as watertight as it looked; older people, told they can stay in and simply order food online, are being left with little choice but to venture out when supermarket delivery slots are booked solid for weeks.
  • But as time goes on, this virus may create unexpected new divides too. We desperately need mass antibody testing, said to be only weeks away, to establish who has already had the virus and might now be immune, on top of the existing tests showing who has it now. Reliable testing would let key workers go back to the frontline – or in some cases back home – and others return to the kind of non-essential jobs that keep an economy ticking over.
  • It may seem churlish to dwell on what divides us rather than what we are discovering we have in common. But the lesson of an epidemic that has seen doctors raiding DIY stores for protective masks, and children separated from their mothers by cold hard glass, is that it pays to be one step ahead, not running to catch up; that where we are now is not necessarily where we will be tomorrow. A crisis that has so far brought us together may soon, if we’re not careful, begin to push us apart.
