'Superspreader' Events May Be Responsible for 80% of COVID Infections

Some scientists now say “superspreader” events may be responsible for at least 80 percent of coronavirus infections.

A report on the website of The Telegraph, a British newspaper, details some findings that “closely packed markets, vigorous dance classes, loud bars and choirs” may be the primary culprits in the spreading of the virus.

The public is already aware that established superspreaders of the virus can include “hospitals, nursing homes, large dormitories, food processing plants and food markets.”

One of the largest spreaders, however, according to the article, came from a bar in the Tyrolean Alps. The Telegraph said hundreds of infections in Britain, Germany, Iceland, Norway and Denmark have been traced back to the Kitzloch bar, “known for its après-ski parties.”

A South Korean study found that “Intense physical exercise in densely populated sports facilities could increase risk for infection” of the coronavirus. It found that 112 people were infected with the virus within 24 days after participating in “dance classes set to Latin rhythms” at 12 indoor locations.

In other studies, choir members were found to be susceptible to contracting the virus, but scientists believe singing was not the only pathway of the spread during the early days of the contagion before social distancing was observed. The coronavirus was likely spread when choir members greeted each other, shared drinks and “talked closely with each other.”

The newspaper account said the virus swept through an Amsterdam choir, infecting 102 of its 130 members.
