EXPLAINER: Is China sharing enough COVID-19 information?

TAIPEI, Taiwan (AP) — As COVID-19 rips through China, other countries and the World Health Organization are calling on its government to share more comprehensive data on the outbreak. Some even say many of the numbers it's reporting are meaningless.

Without basic data like the number of deaths, infections and severe cases, governments elsewhere have instituted virus testing requirements for travelers from China. Beijing has said the measures aren't science-based and threatened countermeasures.

Of greatest concern is whether new variants will emerge from the mass infection unfolding in China and spread to other countries. The delta and omicron variants developed in places that also had large outbreaks, which can be a breeding ground for new variants.

Here's a look at what's going on with China's COVID-19 data:

WHAT IS CHINA SHARING AND NOT SHARING?

Chinese health authorities publish a daily count of new cases, severe cases and deaths, but those numbers include only officially confirmed cases and use a very narrow definition of COVID-related deaths.

China is most certainly doing their own sampling studies but just not sharing them, said Ray Yip, who founded the U.S. Centers for Disease Control office in China.

The nationwide tally for Thursday was 9,548 new cases and five deaths, but some local governments are releasing much higher estimates just for their jurisdictions. Zhejiang, a province on the east coast, said Tuesday it was seeing about 1 million new cases a day.

If a variant emerges in an outbreak, it's found through genetic sequencing of the virus.

Since the pandemic started, China has shared 4,144 sequences with GISAID, a global platform for coronavirus data. That's only 0.04% of its reported number of cases — a rate more than 100 times less than the...
