“RESULTS An estimated 1.87 million (95% CI, 0.71 million-4.43 million; 1.33 per 1000 population) excess deaths occurred among individuals 30 years and older in China during the first 2 months after the end of the zero COVID policy. Excess deaths predominantly occurred among older individuals and were observed across all provinces in mainland China except Tibet.
CONCLUSIONS AND RELEVANCE In this cohort study of the population in China, the sudden lifting of the zero COVID policy was associated with significant increases in all-cause mortality. These findings provide valuable insights for policy makers and public health experts and are important for understanding how the sudden propagation of COVID-19 across a population may be associated with population mortality.”

A new analysis suggests that the Omicron variant has comparable intrinsic severity to the ancestral (Wuhan) SARS-CoV-2 strain, but its effective severity is substantially lower because of vaccination.

Omicron, Delta, Alpha, and More: What To Know About the Coronavirus Variants

Omicron Severity:
Scientists are still working to learn more about whether the current Omicron strains cause more severe disease than their predecessors. Data has suggested that the original Omicron strain was less severe, in general, than previous variants, according to the CDC. But it has also been noted that surges in cases may lead to significant increases in hospitalizations and deaths, as they did during the variant’s spread at the beginning of 2022, when the estimated death rates went as high or higher than they were at the time of the Delta variant surge in the previous autumn.

In Hong Kong, which also had tight pandemic controls and low vaccination and booster rates among older people, Omicron spread widely earlier this year. At its peak the death rate was among the highest recorded globally during the pandemic.
mainland Chinese has never received the education of facts from the childhood. so even some of them become expertise, still they lack the critical thinking.
港大文章原文：At 24 hours after infection, the Omicron variant replicated around 70 times higher than the Delta variant and the original SARS-CoV-2 virus. In contrast, the Omicron variant replicated less efficiently (more than 10 times lower) in the human lung tissue than the original SARS-CoV-2 virus, which may suggest lower severity of disease.
