COVID-19 cases rise across Europe amid new variant circulation

Health authorities in Europe are observing a rise in COVID-19 activity as the virus enters an endemic phase. In France, Santé publique France reported an ascending wave at the end of September 2026, evidenced by rising viral concentrations in wastewater and a significant increase in medical consultations and emergency room visits. While case numbers are climbing, experts note that clinical presentations for most healthy adults resemble standard flu-like syndromes.

In Italy, the Istituto Superiore di Sanità and other experts indicate that while official reported cases remain relatively low due to reduced testing compared to the pandemic era, there is increased public interest and online searches regarding the virus. Microbiologists suggest the current surge is driven by factors such as the return to school and work, increased time in enclosed spaces, and waning immunity.

New variants, including descendants of the JN.1 strain such as NB181 and XFG, are circulating. These variants appear more capable of evading existing antibody responses, leading to higher rates of reinfection, though there is currently no evidence of increased clinical severity. The World Health Organization maintains a moderate global risk level, emphasizing the need to protect vulnerable populations. Vaccination campaigns in France are scheduled to begin in mid-October.
