The rate of new coronavirus cases reported in China has dwindled for two consecutive days — but officials say the worst might not be over yet, according to a new report.

World Health Organization Director-General Tedros Adhanom Ghebreyesus told reporters at a Friday news conference that there are at least 31,211 confirmed cases of the illness in China and at least 637 deaths, CNBC reported.

But while officials said Wednesday that the number of confirmed cases grew by more than 3,100 over the previous 24 hours — the most cases in a single day since the outbreak started Dec. 31 — the vast majority were in China, with 80 percent of those within Hubei province, where the virus originated in Wuhan.

Still, it’s “too early” to tell when the virus will peak again or where it could spread, Dr. Mike Ryan, executive director of WHO’s emergencies program, told reporters.

“We need to be very careful on making any predictions,” he said. “There are cycles of transmission, and we may see those cases increase in the coming days, but at least for the moment, things are stable.”

The agency also confirmed it has sent medical supplies, including masks, gloves, gowns and diagnostic tests, around the world.

Officials warned against stockpiling protective gear — which is becoming increasingly expensive as availability has decreased. The gear should be reserved for the most heavily impacted regions, the WHO said.
