Here are the latest developments in the coronavirus crisis: The pandemic has killed at least 820,180 people worldwide since surfacing in China late last year, according to a tally from official sources compiled by AFP at 1100 GMT on Wednesday. More than 23.9 million cases have been registered in 196 countries and territories. The United States has recorded the most deaths with 178,524, followed by Brazil with 116,580, Mexico with 61,450, India with 59,449 and Britain with 41,449 fatalities. Britain's economy will lose about £22 billion ($29 billion, 24 billion euros) this year on the collapse of global travel, which could imperil three million jobs, an industry body forecasts. International visitor spending could plunge by 78 percent from 2019, equating to a loss of £60 million per day or £420 million a week, the World Travel & Tourism Council (WTTC) predicts in a key report. France's prime minister urges the population to take "responsibility" for limiting the outbreak by wearing masks to protect one another. "People will contaminate others," he warns in an interview with radio channel France Inter. "I appeal to a sense of responsibility." Asked whether the government could issue new stay-at-home orders if the situation spirals out of control, Jean Castex says "all hypotheses" are on the table, though a new lockdown is "not the goal" given the severe economic impact. Britain reverses its policy on wearing facemasks in schools in England, prompting fresh criticism about its handling of the pandemic. Ministers had insisted face coverings were not necessary when children go back to school next week, but in new guidance the government now advises secondary school students and staff should wear face coverings in corridors and communal areas. Pope Francis will resume limited public weekly audiences early next month, the Vatican announces, six months after the head of the Catholic Church halted the practice. The Wednesday hearings will be held in a closed courtyard of the Vatican's Apostolic Palace, where a maximum of 500 seats will be placed. Myanmar expands a lockdown in conflict-wracked Rakhine state to cover four more townships, halting the movement of about one million people as the number of cases climbs steadily. The agent for Jamaican sprint king Usain Bolt confirms the eight-time Olympic gold medallist has tested positive for the virus, but says he is not showing any symptoms. burs-eab/jmy/txw
