This report indicates the majority of coronavirus cases within New York originate from Europe rather than China. No sentinel sequences were directly connected to sequences from Wuhan, China, where the outbreak originated.

Impact of age structure and vaccine prioritization on COVID-19 in West Africa, 2022.09.08,
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9454155/ .
Contrary to early predictions that sub-Saharan Africa (SSA) would bear a disproportionate share of the burden of COVID-19 due to the region's vulnerability to other infectious diseases, weak healthcare systems, and socioeconomic conditions, the pandemic's effects in SSA have been very mild in comparison to other regions. In this study, the authors formulate a model framework consisting of a basic model (in which only susceptible individuals are vaccinated), a vaccine-structured model, and a hybrid vaccine-age-structured model to assess the dynamics of COVID-19 in West Africa (WA). Simulations of the models show that controlling the COVID-19 pandemic in WA (by reducing transmission) requires a proactive approach, including prioritizing vaccination of more youths or vaccination of more youths and elderly simultaneously. Moreover, complementing vaccination with a higher level of mask compliance will improve the prospects of containing the pandemic. Furthermore, the emergence of a more transmissible variant or easing the existing measures that are effective in reducing transmission will result in more devastating COVID-19 waves in the future. To conclude, accounting for age-structure is important in understanding why the burden of COVID-19 has been low in WA and sustaining the current vaccination level, complemented with the WHO recommended NPIs is critical in curbing the spread of the disease in WA.

Unexpected Increase in Invasive Group A Streptococcal Infections in Children After Respiratory Viruses Outbreak in France: A 15-Year Time-Series Analysis, Open Forum Infectious Disease, 2023.04.06,
https://doi.org/10.1093/ofid/ofad188 .
In a 15-year pediatric time-series analysis, we showed a rise of invasive Group A streptococcal (iGAS) infections since October 2022, mainly involving pleural empyema, simultaneously to a respiratory virus outbreak. Physicians should be aware of this increased risk of pediatric iGAS infections, especially in settings with intense respiratory viruses' circulation.
