IT has been almost a year since Covid-19 was declared a pandemic, and we now know much more about the coronavirus since all the lockdowns started. Some questions, of course, remain outstanding as the virus keeps mutating and our knowledge keeps evolving.
Among the important facts that have been established and reaffirmed, however, is that outdoor transmission is rare, and that while it is not nil, the chance of getting the virus in open air settings is much lower compared to getting it indoors. In one study in China (Qian et al. 2020), the researchers found only one outdoor outbreak involving two individuals among 7,324 identified cases. Conversely, some studies suggest that in closed settings, physical distancing and face mask wearing may not be perfectly protective.
