Shanghai's life-saving efforts against the current omicron wave of the COVID-19 pandemic

Characteristics and implications of Omicron variant associated digestive system infections – Correspondence

“…A new round of local SARS-CoV-2 outbreaks has occurred in Shanghai, China since late February 2022, and the virus genomes belong to the BA.2 variant of Omicron [ 4 ]。The cumulative number of infected people had reached more than 650,000 by late May 2022, and asymptomatic infection cases accounted for more than 90% of the total infected population. Deaths associated with this round of epidemic occurred mainly in elderly people over 60 years of age with a variety of serious underlying diseases and who had not been vaccinated or not fully vaccinated.…”

Renaming the SARS‐CoV‐2 Omicron sublineages as SARS‐CoV‐3 is contrary to nomenclature standards based on evolutionary and serological evidence

“…The vaccination rate among death cases was extremely low, only 4.97%. 6 This number implies that the current vaccines used in China, including inactivated vaccines, adenovirus‐vector‐based vaccines and receptor‐binding domain (RBD)‐based subunit vaccines, as well as the mRNA‐based BNT162b2 vaccines, could still provide efficient protection against severe disease caused by different sublineages of the Omicron variant. 7 Moreover, Shanghai has persisted in aiming for dynamic zero coronavirus disease 2019 (COVID‐19) at the community level.…”

“…During the recent wave of SARS‐CoV‐2 infection in Shanghai, a total of 620 911 cases were identified, including 57 260 symptomatic cases and 576 fatalities, until 16 May 2022. The vaccination rate among death cases was extremely low, only 4.97% 6 . This number implies that the current vaccines used in China, including inactivated vaccines, adenovirus‐vector‐based vaccines and receptor‐binding domain (RBD)‐based subunit vaccines, as well as the mRNA‐based BNT162b2 vaccines, could still provide efficient protection against severe disease caused by different sublineages of the Omicron variant 7 .…”

Expert suggestion for diabetes management during the recent COVID‐19 pandemic

“…Compared to the other variants of SARS-CoV-2, omicron is more transmissible and with a shorter incubation period than the other variants such as delta, albeit with a reduced impact on lower respiratory tract and rates of hospital admission. 1,2 Acute and chronic infections are the common complications of diabetes. Although there is insufficient evidence to confirm that patients with diabetes are more susceptible to COVID-19 than the general population, multiple studies have shown that the patients' underlying condition such as diabetes was associated with an increased risk of poorer clinical outcomes including mortality for these patients.…”
