JN.1

JN.1 is a novel coronavirus variant that emerged in Luxembourg in August 2023 and has since spread to several countries. It is characterized by a high transmissibility, and is causing a global surge of infections, hospitalisations, ICU admissions and deaths, and may surpass the previous Omicron waves. Current vaccines, treatments and testing are expected to remain effective, but more studies are needed to confirm this. This short communication provides an overview of the epidemiological, clinical, and virological features of JN.1 and its impact on global health.
