Significant increases in cases in Libya, Iran, Iraq and Tunisia, with sharp rises expected in Lebanon and Morocco.
The World Health Organization has said the second stage of an investigation into the origins of coronavirus should include further studies in China and lab “audits”.
In a closed-door briefing to member states on Friday, WHO chief Tedros Adhanom Ghebreyesus proposed five priorities for the next phase of the investigation.
They included “audits of relevant laboratories and research institutions operating in the area of the initial human cases identified in December 2019”, the news agency Reuters reported, citing a copy of his opening statement provided by WHO.
He also suggested investigators should focus on “studies prioritising geographic areas with the earliest indication of circulation of SARS CoV-2”.
And he called for more studies of animal markets in and around the Chinese city of Wuhan, where COVID-19 was first detected.
The UN health agency has been under intensifying pressure for a new, more in-depth investigation of COVID-19’s origins.
Diplomats said that China, which has resisted a return by international scientists, voiced objections at the closed-door talks saying: “This plan is not a basis for future studies.”
A WHO-led team spent four weeks in and around the central city of Wuhan with Chinese researchers and said in a joint report in March that the virus had probably been transmitted from bats to humans through another animal.
But countries including the United States and some scientists have demanded further investigation, particularly into the Wuhan Institute of Virology which was conducting research into bats.
“Finding the origins of this virus is a scientific exercise that must be kept free from politics. For that to happen, we expect China to support this next phase of the scientific process by sharing all relevant data in a spirit of transparency,” Tedros said.
China has called the theory that the virus may have escaped from a Wuhan laboratory “absurd” and said repeatedly that “politicising” the issue would hamper investigations.
At a regular news briefing on Friday, when asked about Tedros’s earlier comments on the need for more data from China, China’s foreign ministry spokesperson Zhao Lijian said that some data was unable to be copied or leave China as it involved personal information.
