A new study suggests that the common cold virus could offer some level of protection against Covid-19.
Research published by scientists at the [broken link removed] found that rhinovirus, which causes the common cold, triggers an immune response that appears to block SARS-CoV-2 replicating in cells of the respiratory tract. Further mathematical calculations studies showed that this virus-virus interaction could have a population-wide effect and that an increasing prevalence of rhinovirus could reduce the number of new Covid-19 cases.

While it's interesting news it's a very misleading headline. Rhinovirus is one of a large number of viruses which cause the "common cold". It is responsible for 30-50% of common cold infections. Therefore 30-50% of common colds could offer some level of protection.
 
In the context of being allowed outside etc I thought this from the might be of interest. It's kind of stating the bleedin' obvious but sometimes that's necessary.
 
Study on the effectiveness of the introduction of mandatory masks in Melbourne...

Co-lead author Dr Nick Scott said the introduction of mandatory mask use by the Victorian Government on 22 July 2020 while Stage 3 restrictions were in place, turned an exponential increase in community transmission into an exponential decrease, almost overnight.
“We had a unique situation in Melbourne where masks were made mandatory as a single policy change, and compliance went from low use to very high use of masks in the community very rapidly,” Dr Scott, Head of Burnet’s Modelling and Biostatistics Group, said.
