What we know about the new 'cicada' COVID-19 variant
PBS • • health
Key Points:
- The new COVID-19 variant BA.3.2, nicknamed "cicada," first appeared in 2024, resurfaced in the U.S. late last year, and has recently gained traction in Europe, prompting monitoring by health experts.
- "Cicada" is part of the omicron family with 70 to 75 mutations that may help it evade immune defenses from current vaccines, though it currently accounts for a minority of U.S. cases and is more prevalent in parts of Northern Europe.
- There is no evidence yet that BA.3.2 causes more severe illness or distinct symptoms compared to previous variants, and its transmissibility remains uncertain.
- Current COVID-19 vaccines may offer reduced protection against infection by BA.3.2 but are still expected to protect against severe disease; annual vaccination is recommended, especially for older adults and those with chronic conditions.
- Traditional at-home COVID-19 tests remain effective at detecting the "cicada" variant, as they target stable parts of the virus, but individuals with symptoms should still get tested and consult healthcare providers.
