Why are the number of new cases in Wuhan higher than that in the whole of Hubei Province? Why are there reductions in the number of new cases?

The official statistics of the number of new cases of COVID-19 are released to the public every day, but many people are wondering why the number of new cases in Wuhan is higher than that in the whole province of Hubei. A month has passed since the outbreak, and the number of infections in Wuhan has not been under control, which makes people a little panic. At this time, the official data and answers were given by the authorities. Let's take a look!

Why are the number of new cases in Wuhan higher than the entire Hubei province?

Today's Hubei Provincial Epidemic Report shows that Hubei Province has 349 new confirmed cases of COVID-19, while Wuhan City has 615 cases. Many netizens are wondering if this is a mistake? A closer look reveals that some of the newly confirmed cases in each city (state) were reduced. The province's newly confirmed cases of COVID-19 = the sum of the newly confirmed cases of COVID-19 in each city (state) (if it is a reduction, it is a subtraction).

In fact, the new additions and reductions should be listed separately, so that the data can reflect the real situation (10 new additions and then 10 reductions are definitely different from 0 new additions

Why does devaluation exist?

On the 19th, the National Health Commission released the sixth edition of the diagnosis and treatment plan for new coronavirus pneumonia. The diagnostic criteria eliminated the distinction between Hubei Province and other provinces outside Hubei Province, and unified them into two categories: "suspected cases" and "confirmed cases". Confirmed cases must meet one of the following evidences: positive nucleic acid test or highly homologous gene sequencing.

Previously, according to the fifth edition of the treatment plan, Hubei Province included the number of "clinically diagnosed" cases in the number of confirmed cases, that is, suspected cases with radiological features of pneumonia, but negative nucleic acid test results, were classified as confirmed cases. Now, according to the sixth edition of the diagnosis and treatment plan, the previous "clinically diagnosed" cases are no longer classified as confirmed cases because they do not meet the nucleic acid test positive, so the number of confirmed cases has been reduced.

In fact, there is no miscalculation or error in the reported epidemic data. You only need to carefully read the full text and picture interpretation released by the official to understand. You may not understand this reduction very well. These algorithm standards are based on the sixth edition of the new coronavirus pneumonia diagnosis and treatment plan. The previous algorithm was the fifth edition of the diagnosis and treatment plan. The algorithm standards are based on the latest version, so there will be reductions. For the instructions of these versions of the diagnosis and treatment plans, you can go to the official release. I hope that everyone will popularize the official epidemic prevention knowledge release, epidemic situation release, and diagnosis and treatment plan release.
