The World Health Organization on Friday once again urged China's health officials to regularly share specific and real-time information on the COVID-19 situation in the country, as it continues to assess the latest surge in infections.

The agency has asked Chinese officials to share more genetic sequencing data, as well as data on hospitalizations, deaths and vaccinations.

Official figures from China have become an unreliable guide as less testing is being done across the country following the recent easing of the strict "zero-COVID" policy.

WHO has previously said that China may be struggling to keep a tally of COVID-19 infections.

The agency has invited Chinese scientists to present detailed data on viral sequencing at its meeting of a technical advisory group scheduled for Jan. 3.

COVID infections have risen across China this month after Beijing dismantled its zero-COVID policies including regular PCR testing on its population. The United States, South Korea, India, Italy, Japan and Taiwan have all imposed COVID tests for travelers from China in response.
