Medical Case Reports

Concerns about a potential resurgence of COVID-19 are mounting as summer 2024 approaches.  This is driven by several indicators, including social media posts, healthcare data, and wastewater surveillance across different regions. Our study findings corroborate this trend.  While many forecasters anticipate a surge, others expect a gradual increase through the end of May, and then a decline again around early June. Reports from social media suggest emerging clusters of COVID-19 in Texas, several Canadian provinces, the UK, and on cruises in northern regions such as a Norwegian cruise to Alaska.  Data from Alberta's Respiratory virus dashboard   (total weekly laboratory-confirmed COVID-19 cases) and wastewater surveillance in Calgary indicate an uptick in COVID-19 cases starting April 2024. The most recent statistics from Alberta Health reveal a significant increase in hospitalizations due to COVID-19, with 114 individuals currently hospitalized—an incr...

While the current SARS-COV-2 viral activity levels may seem reassuring ( back to the levels seen in October-November 2023 ), the evolving world of JN.1 offshoots, where the next generation of variants is taking shape, presents a compelling case for anticipating the potential challenges that lie ahead.  From the widespread presence of JN.1.16 across continents to the emerging dominance of JN.1.13 in the U.S., the current variant landscape is rapidly shifting, although the potential implications for the future are not quite clear.  The roots of the pandemic can be traced back to lineage A, with many initial sequences originating from China and subsequently spreading globally, including to regions such as South East Asia, Japan, South Korea, Australia, the USA, and Europe. Lineage B followed as the second major haplotype, with subsequent evolutions leading to the emergence of various sublineages. In 2020, we witnessed the emergence of variants such as Alpha (B.1.1.7) and Delta (...
