The number of new Covid-19 cases can be lowered by wearing a mask, social distancing and hand washing, according to an analysis of evidence from 72 global studies.
The study found that mask wearing was the most effective public health measure at reducing the incidence of Covid-19.
The researchers noted that the finding was not statistically significant because of the small number of studies that assessed hand washing.
The researchers said that it was not possible to evaluate other public health measures due to differences in the way studies were designed and conducted.
The researchers said the restrictions are not sustainable, have significant economic and social impacts, and must be carefully assessed to weigh potential positives against negatives.
The use of masks in the fight against Covid-19 has become a flashpoint in the culture war between individual liberties and the public good. In the U.S., mask mandates have been a hot button issue for politicians to jump on, even as cases and deaths soared. Some states have prevented local officials from putting their own rules in place because of the high tensions.
The control of the Pandemic is likely to be dependent on both high vaccination coverage and adherence to effective and sustainable public health measures. The researchers wrote that more research is needed to assess the effectiveness of public health measures.
The quote is crucial.
The lack of good research on public health measures to tackle Covid-19 is one of the tragedies of the Pandemic. More and better research is needed.
The number is big.
4%. According to the editorial, Covid-19 funding goes into assessing public health measures. The lack of investment in public health measures is puzzling, considering the central importance of public health measures.
Surprising fact.
There was only one randomized trial of a public health measure. Hundreds of trials have been completed for pharmaceutical treatments.
The masks become a flash point in the culture wars.
The killing of a Georgia cashier is the latest in a string of killings.
The effectiveness of public health measures to reduce the incidence of covid-19, the transmission of the coronaviruses, and the mortality of covid-19 is reviewed.
