WHO Warns Young People COVID-19 May Hit Hard VOA News The resurgence of the coronavirus in many countries is "driven in part by younger people letting down their guard during the Northern Hemisphere summer," World Health Organization Director-General Tedros Adhanom Ghebreyesus said Thursday. Young adults, many without masks, are ignoring social distancing recommendations to pack bars, nightclubs, and beaches that have been reopened since authorities lifted coronavirus restrictions. "The majority of young people infected tend to have more mild disease. But that's not always consistent," said Maria Van Kerkhove, a WHO epidemiologist who called nightclubs "amplifiers of transmission." Young people who show mild or no symptoms can spread the virus to more-vulnerable older people. In Brazil, President Jair Bolsonaro, who tested positive for the coronavirus on July 7 and then negative last Saturday, said that after 20 days indoors he had mold on his lungs. He is being treated with antibiotics. He had repeatedly referred to COVID-19 as "a little flu." Brazil, as of Thursday evening, had 2.6 million confirmed cases and 91,263 deaths, according to the [1]Johns Hopkins Coronavirus Resource Center. Among the confirmed cases is Brazil's first lady, Michelle Bolsonaro, who tested positive on Thursday, according to a statement from the presidential palace. Science and Technology Minister Marcos Pontes also said he had tested positive for the virus, making him the fifth cabinet minister diagnosed publicly. The leader of the northeastern Spanish region of Catalonia is warning young adults to stop partying or authorities may have to reimpose harsh restrictions. Britain is reporting its highest number of new COVID cases since late June, with officials warning that more quarantines may be necessary. British health officials registered 846 new cases Thursday and Minister for Health and Social Care Matt Hancock said a second wave of the virus is rolling across Europe and that Britain must defend against it. "It is absolutely vital as a country that we continue to keep our focus and our discipline, and that we don't delude ourselves that somehow we are out of the woods or that that is all over, because it isn't all over," Prime Minister Boris Johnson said Thursday. British authorities added Luxembourg to the country's quarantine list, meaning travelers from there must isolate for 14 days after entering Britain. Spain, which had been dropped from the list, has been reinstated and other countries may be added. Botswana's capital, Gaborone, reimposed a two-week lockdown on Thursday after a surge in new confirmed COVID-19 cases. The increase came as the WHO warned of easing coronavirus restrictions throughout Africa. The WHO says the number of infections on the continent has doubled in the past month.
