WHO: Global new COVID-19 cases drop by 25%

Introduction: The new crown has continued so far, human beings have paid a tragic price, and many people are anxious about when the epidemic will be a head.

The WHO released the latest realistic data

WHO: New COVID-19 cases drop by 25%

On August 17, the World Health Organization (WHO) released a report on the COVID-19 outbreak, showing that the number of COVID-19 cases reported globally fell by 25% last week, and the number of deaths fell by 6%, but the number of COVID-19 deaths in parts of Asia is still at a high level (Figure 1

As of 14 August 2022, 587 million confirmed cases and 6.

Weekly number of new cases reported in all six regions of the world increased weekly new deaths in the Western Pacific (+31%) and South-East Asia (+12%)

At the national level, the countries with the highest number of new cases reported each week are: The Republic of Korea (866,830 new cases; +22%), Japan (1395301 new cases; -7%), new cases in the United States (679653; -14%), Germany (271277 new cases; -25%) and Italy (193305 new cases; -32%）

To date, 37 studies from 15 countries (Argentina, Brazil, Canada, Chile, Czech Republic, Denmark, Finland, Norway, Israel, Qatar, Singapore, South Africa, United Kingdom, United States of America and Zambia) have collectively evaluated the protective effects

Compared to the original COVID-19 strain and the four previously transmitted variants, the COVID-19 vaccine has significantly reduced VE protection against severe diseases, symptomatic diseases and infections when confronted with the Omicron variant

Note: EUL (Emergency Use Listing) represents emergency use list, HNR (high non-response) indicates high non-response, and the median percentage response of all studies <75%.

For severe cases, VE hardly decreased

In all studies, the first booster dose vaccination improved VE for severe disease, with 37 (95%) of the 39 estimates of VE between 14 days and 3 months of receiving the booster dose ≥ 70%.

The pace of mutation of the new crown virus will not stop, and the direction of mutation is beyond human control

The vast majority of people in our country do not have immunity to the new crown virus, are susceptible to the new crown virus, and after the onset of infection, some people will develop critical illness and even cause death
