BANGKOK (AFP) - Thailand's confirmed coronavirus cases rose by a third to nearly 600, the kingdom announced Sunday (March 22), as fears of a full-blown crisis take hold in a country largely spared until now.
Thailand's health ministry announced the spike was mainly in the capital, but warned residents of Bangkok not to leave and risk spreading the virus around the country.
"We would like you to stay home. Do not travel upcountry," said health ministry official Taweesin Visanuyothin.
