Chilean Army / Reuters Antarctica is no longer the only continent free of the pandemic. Thirty-six people stationed at the General Bernardo O'Higgins Riquelme Antarctic base had tested positive for the virus, Chilean officials said this week. The permanent research station is located on tip of the continent south of Chile. Of those infected, 26 are members of the Chilean army and 10 are civilian maintenance personnel, authorities said in a statement to the Spanish-language television channel 24 Horas. The officials added that contact tracing was underway and those who tested positive were in isolation. No other countries have publicly reported positive cases on Antarctica, USA Today reported, and there have been concerted efforts to ensure the virus did not reach the remote continent.
