Public health experts at the World Health Organization have begun discussing how and when to call an end to the global Covid-19 crisis, exploring what would be an important milestone more than two years after the emergence of the virus.

The WHO said it isn’t currently considering such a declaration. While cases have fallen in many places, fatalities have spiked in Hong Kong, and this week China reported more than 1,000 new daily cases for the first time in two years.
