Researchers in Germany may have good news for frustrated concert-goers around the world whose activities are being restricted by the spread of the coronavirus.

Analysis of an indoor concert staged by scientists in August suggests that the impact of such events on the spread of the coronavirus is "low to very low", as long as organisers ensure adequate ventilation, strict hygiene protocols, and limited capacity.

"There is no argument against holding such a concert," said Dr Michael Gekle, part of the team at Martin Luther University Halle-Wittenberg that led the research. "The risk of getting infected is very low."

Some experts were sceptical about the results, saying more information is needed about how researchers used the models.
