The coronavirus pandemic has infected more than 424,000 people and killed at least 18,000 across the world. More than 108,000 people have recovered so far, mostly in China.
After a months-long lockdown, China's Hubei province, home to more than 50m people, has lifted its tough restrictions on movement.
Huge crowds are using trains and buses as people take their first opportunity to travel. Hubei's capital city Wuhan - the initial epicentre of the outbreak - will allow residents to leave from 8 April.
At least 19,246 deaths have been recorded since the virus first emerged in December, according to an AFP tally compiled at 1100 GMT Wednesday based on official sources.
