Daily roundupSaturday's key coronavirus developments from Luxembourg and abroad

Starting with Luxembourg

• Until mid-August, new Covid-19 infections in Luxembourg decreased, but in the last two weeks they have nearly returned to late July levels. They are now predicted to rise to 100 per day.

• Fitness coaches in the Grand Duchy have noticed that many people exercised less during lockdown, taking a toll on people’s fitness.

• Are pandemic restrictions at Schrassig prison inhumane? A lawyer for one of the inmates thinks so, and has raised concerns about the strict visiting rights that remain in place.

And abroad

• US President Joe Biden said Friday that China was withholding “critical information” on the origins of Covid-19 after the US intelligence community said it did not believe the virus was a bioweapon -- but remained split on whether it escaped from a lab.

• India has given more than 10 million Covid-19 jabs in a single day for the first time, authorities said Saturday, as the South Asian giant bolsters its defences for a predicted new surge.

• The Delta variant of the virus that causes Covid-19 doubles the risk of hospitalisation compared to the Alpha variant it has supplanted as the dominant strain worldwide, researchers reported Saturday in The Lancet.

• During Spain’s tough lockdown last year, Paralympic triathlon champion Susana Rodriguez trained furiously at home and helped fight the coronavirus in her job as a doctor. Now she’s won gold in Tokyo.

• In Brazil, meanwhile, the pandemic is pushing new homeless onto Sao Paulo streets. When Monica’s landlord suddenly doubled the rent on the room where she lived with her three daughters in Sao Paulo, she says they had little choice but to go live on the streets.
