Vaccines have reduced severe disease and death from Coronavirus Disease 2019 (COVID-19). However, with evidence of waning efficacy coupled with continued evolution of the virus, health programmes need to evaluate the requirement for regular booster doses, considering their impact and cost-effectiveness in the face of ongoing transmission and substantial infection-induced immunity. ⋯ Our modelling suggests that regular boosting of the high-risk population remains an important tool to reduce morbidity and mortality from current and future SARS-CoV-2 variants. Our results suggest that focusing vaccination in the highest-risk cohorts will be the most efficient (and hence cost-effective) strategy to reduce morbidity and mortality.

To determine how the severity of prior history (Hx) of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection influences postoperative outcomes after major elective inpatient surgery. ⋯ Impact of COVID-19 on postoperative outcomes is dependent on the severity of illness, with only moderate and severe disease leading to a higher risk of adverse outcomes. Existing perioperative policies should be updated to include consideration of COVID-19 disease severity and vaccination status.

To determine the association between the presence of upper respiratory tract viral infection symptoms and occurrence of perioperative respiratory adverse events (PRAE) in children with positive viral screening, and to analyze the risk of PRAE in children with SARS-CoV-2 compared to non-SARS-CoV-2 infection. ⋯ There was no significant difference in the incidence of PRAE between symptomatic and asymptomatic children with laboratory confirmed viral respiratory infection, and between children with the Omicron variant of SARS-CoV-2 compared to non-SARS-CoV-2 respiratory viruses. However, the risk was increased in children with recent fever.

Observational StudyAnalysis of Twitter conversations in obstetric anesthesiology using the hashtag #OBAnes during the onset of the COVID-19 pandemic.
#OBAnes is the most used hashtag in obstetric anesthesiology. The primary objective of the study was to characterize #OBAnes tweets at the onset of the COVID-19 pandemic. ⋯ Twitter facilitated thousands of obstetric anesthesia-related discussions during the onset of the COVID-19 pandemic, with most conversations centering on anesthesia type (neuraxial or general anesthesia).

Taiwan experienced a relatively low incidence of COVID-19 before 2022. However, from April 2022 to March 2023, the country was struck by a nationwide outbreak that occurred in three waves. Despite the considerable magnitude of the epidemic, the epidemiological characteristics of this outbreak have yet to be clearly understood. ⋯ During the three waves of COVID-19 epidemic, the numbers of cases and deaths gradually declined, while the vaccine coverage increased. It may be appropriate to consider easing restrictions and returning to normality. However, continued monitoring of the epidemiological situation and tracking the emergence of new variants are crucial to prevent the possibility of another epidemic.
