**Excerpt:** The COVID-19 variant BA.3.2, nicknamed “Cicada,” is spreading globally but not dominating cases. Here’s what to know.
Key Points
– The “Cicada” variant (BA.3.2) was first identified in November 2024 and is now present in at least 23 countries and 25 U.S. states.
– It belongs to the Omicron family and has 70 to 75 mutations, potentially evading some vaccine protections.
– Current data show no significant increase in severe disease or hospitalizations linked to this variant.
– Symptoms remain consistent with COVID-19, including fever, cough, and shortness of breath.
– Vaccination is advised, especially for high-risk populations, with recommendations to get the vaccine by late May to prepare for potential summer surges.
Overview of the “Cicada” Variant
The COVID-19 variant known as BA.3.2, informally named “Cicada,” is currently under observation by health authorities including the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO).
Geographic Spread
Since its identification in November 2024, the Cicada variant has been detected in 23 countries and at least 25 states across the U.S. As of February, it has not yet become the predominant strain, sparking discussions among health experts regarding its potential trajectory.
Characteristics of the Variant
Cicada is a highly mutated variant, part of the Omicron family, boasting 70 to 75 mutations. Recent studies indicate that the current COVID-19 vaccines may be less effective against this strain compared to earlier ones, although they still offer some level of protection. Dr. William Schaffner, an infectious disease specialist, emphasizes that it is too early to determine whether this variant will significantly alter current infection trends.
Severity of Cases
Currently, the CDC reports no nationwide increase in severe COVID-19 cases. Despite fluctuations in state-level data, overall case rates, emergency visits, and hospitalizations are declining. Nevertheless, states like Massachusetts and Florida may see rising case numbers. Dr. Celine Gounder, a medical contributor, noted that there is no evidence suggesting that the Cicada variant causes more severe illness than previous strains.
Symptoms and Vaccination Recommendations
Common symptoms associated with COVID-19, including fever, cough, shortness of breath, sore throat, and congestion, remain consistent. The CDC emphasizes the importance of vaccination, particularly for those aged 65 and older, individuals unvaccinated, and those at high risk for severe illness. Dr. Schaffner recommends that vulnerable populations receive their vaccinations by late May to ensure adequate protection as summer approaches.
In summary, while the “Cicada” variant is spreading, ongoing monitoring and vaccination efforts are crucial in managing its potential impact.
