Biologist: ‘I’d like to see masks mandated in schools’

As Covid-19 cases start to rise again, computational biologist David Welch wants to see mask restrictions tighten, RNZ reports. “I think it’s very sensible to stay at orange at this point. Orange isn’t particularly restrictive but it does help with masking and it sets clear rules around isolation.” Welch said waning immunity, a new season and new variants are all factors in driving numbers up.
