Looking at the decrease in the number of COVID-19 cases and an increase in vaccination, many countries in the world are relaxing compulsory norms around wearing masks. However, some scientists are not in support of this. They are of the opinion that even after getting fully vaccinated one must wear a mask indoors like in offices, malls, shops, buses, or trains.
In this context, experts are of the view that the US state of New Hampshire formula is the best.
New Hampshire was the last state in New England to start mandating mask-wearing in public to reduce the spread of the COVID-19 SARS-CoV-2. And on April 16 it became the first in the region to lift that mandate, joining several other states around the country that were loosening their pandemic-related restrictions.
According to a report published in Nature magazine, in New Hampshire wearing masks indoors (office, malls, shops etc) is compulsory. If you are roaming on the streets or fields then it is not compulsory.
Epidemiologist Anne Hoen working at Dartmouth College of New Hampshire said that it was necessary to continue with wearing indoor masks. The danger of catching an infection indoors is more. Monica Gandhi, an infectious disease physician at the University of California, San Francisco is also of the belief that there is less danger of catching an infection outdoors.
75% cases dropped in 20 days
Researchers estimate that new cases in the city, home to around 110,000 people, dropped by about 75% during the 20 days after the rule was brought into practice.
Scientists are of the opinion that with the increase in vaccination removing masks could be a decision taken in haste. They attribute many reasons to it.
All have not been vaccinated. There is no full prove data on the results of vaccination.
When Germany made wearing masks compulsory then within 20 days there was a 75% fall in the infection rate.
Rethink on mask guidance
Centers for Disease Control and Prevention (CDC), Atlanta had in its previous guidelines said that whoever had got themselves fully vaccinated could stop wearing masks.
CDC guidelines also said that fully vaccinated people need not follow social distancing norms.
And now, after the CDC released its latest revision, agency director Rochelle Walensky noted that it could change its mask guidance yet again.
