Cicada Variant: A New COVID-19 Concern Emerges Globally

A new COVID-19 variant, named Cicada, has been identified and is associated with a rise in cases globally. Initially identified in South Africa in November 2024, the variant initially spread slowly, with the reason for its current increase in cases remaining undetermined by experts.

Global Footprint and U.S. Presence

According to the Center for Disease Control (CDC), the Cicada variant has been detected in at least 23 countries. Its global spread highlights the continuous evolution of the SARS-CoV-2 virus.

In the United States, Cicada has been detected in wastewater in over 20 states.

Despite its presence in wastewater, the variant has not yet contributed to a large number of new COVID-19 cases across the country. Health officials are closely monitoring this trend.

Expert Observations on Immunity and Severity

The SARS-CoV-2 virus, which causes COVID-19, undergoes constant mutation, leading to the frequent emergence of new variants. Experts have stated that the Cicada variant may present challenges to immune systems.

This means it could potentially exhibit some immunity from existing vaccines or prior infections. However, a significant observation offers some reassurance: the variant is not believed to induce reactions as severe as those caused by earlier strains of the virus.

Official Monitoring Status

Health officials are closely monitoring the Cicada variant as part of ongoing global surveillance efforts. In December 2025, the World Health Organization officially classified it as a "variant under monitoring," underscoring the need for continued vigilance and research.
