Here are the latest developments in the coronavirus crisis:
- Reinfection possible: researchers -
Researchers in Hong Kong say they have discovered the first case of a person who had recovered from COVID-19 only to catch it again.
The patient, a 33-year-old man living in Hong Kong, had tested positive in March, but after two negative tests was found to be positive again in August. Experts say it is too early to draw conclusions.
- More than 809,000 dead -
The pandemic has killed at least 809,255 people worldwide since surfacing in China late last year, according to a tally from official sources compiled by AFP at 1100 GMT on Monday.
More than 23.4 million cases have been registered in 196 countries and territories.
The United States has recorded the most deaths with 176,809, followed by Brazil with 114,744, Mexico with 60,480, India with 57,542 and Britain with 41,429 fatalities.
- China's Xinjiang protests lockdown -
Residents in China's northwestern Xinjiang region complain on social media about what they say are harsh coronavirus lockdown measures after a local outbreak.
A new cluster in Xinjiang's capital Urumqi in mid-July prompted fresh restrictions, with 902 cases officially reported. Officials said this month they had "effectively contained" the cluster, and there have been no new cases reported in the past eight days.
- Plasma treatment -
US authorities announce an emergency authorisation for doctors to use blood plasma from recovered coronavirus patients as a treatment.
The plasma is believed to contain powerful antibodies that can help fight off the disease faster and help protect people from being seriously hurt by it.
European stock markets surge on hopes for a coronavirus treatment, with London up 1.7 percent, Frankfurt 2.4 percent and Paris 2.3 percent at the close.
- Bali keeps out foreign visitors -
Bali's governor says foreign tourists will not be able to visit the Indonesian island for the rest of 2020 due to coronavirus concerns, scrapping a plan to open up from next month.
The reopening plan has been cancelled over concerns about Indonesia's mounting virus cases and with many foreign nationals subject to travel bans in their home countries.
