Millions of South Korean students were ordered back to online classes Tuesday and Mexico launched a nationwide televised schooling programme, highlighting the deepening crisis for children as the coronavirus pandemic drags into a ninth month.
The school closures were part of new measures in many parts of the to halt the disease that has killed more than 813,000 people and infected over 23 million, according to an AFP tally.
The latest high-profile case was sprint legend Usain Bolt, who was in quarantine Monday after undergoing a test for the virus that Jamaican media reported had come back positive.
The retired 100 and 200 metres world-record holder said on Twitter that he was "trying to be responsible" by going into isolation, but he did not confirm the result.
He is one of a growing number of sports personalities to have fallen victim as the virus touches all corners of society.In the education sector, the United Nations estimates at least 60% of the global student population has been impacted by school closures across more than 140 countries.
All schools and kindergartens in the greater Seoul region were told on Tuesday to return to online learning as authorities battled multiple coronavirus clusters. Another 280 infections were reported on Tuesday, taking South Korea's total to almost 18,000.
"The alarming emergence of mass infections since August is turning up as infections of our students and staff members," Education Minister Yoo Eun-hae said.
Taking its toll
In Mexico, around 30 million children began a new school year on Monday with lessons via television in a nationwide experiment in distance learning.
The government has teamed up with four private television stations to broadcast classes across the Latin American country, which has recorded more than 60,000 deaths from the virus. Face-to-face lessons have already been suspended since March.
The government said it chose TV because it reached 94% of the country, compared with between 70%-80% for the internet.
"I'm worried about how good the (lessons) can be through television," said one father, Alfredo Urdiain, whose 11-year-old son Emiliano is taking part.
The social isolation many children are experiencing has also prompted mental health concerns.
"These extraordinary measures of physical and social isolation are taking their toll," said Emmanuel Sarmiento, general director of the Juan N. Navarro children's Psychiatric Hospital in Mexico City.
Anxiety about the pandemic was fuelled Tuesday by an announcement from researchers in Hong Kong that they had identified what they said was the first confirmed case of Covid-19 reinfection, raising questions about the durability of immunity.
The patient, a 33-year-old man living in Hong Kong, tested positive in March but after two negative tests was found to be positive again in August.
Microbiologist Kelvin Kai-Wang To, lead author of the study, said: "Covid-19 patients should not assume after they recover that they won't get infected again."
However experts were uncertain about the significance of the announcement, with some researchers saying the case could be extremely rare. — AFP Relaxnews
