A top public health expert says the evidence on use of #masks in public has become “so strong” it needs urgent attention. He says they could be key intervention to stop transmission. The MOH says they’re not needed. @NewshubNZ #COVID19nz #Masks4All #NZhttps://www.newshub.co.nz/home/new-zealand/2020/04/new-zealand-needs-to-urgently-look-at-wearing-masks-in-public-expert.html …

What is the scenario here? Do you touch your face more often with a mask? No evidence of that. What if you do? You're touching outside of mask. What if someone coughs on you? Well, yeah, outside of your mask is contaminated but OTHERWISE YOU BREATHE IT IN FOR SURE. No extra risk.

We looked for evidence and we really tried to find the scenario in which incorrect mask wearing is increased risk. (We would want to know because then we can warn people). We find no evidence plus no real scenario. So: wash hands after handling masks and change them often.

We already have evidence in NZ of a probable case of that medical scenario with Covid-19. The claim here is that people who are not familiar with wearing masks (practically everyone in NZ) won't use them correctly and therefore put themselves at greater not lesser risk.
