New “Cicada” COVID Variant Draws Attention as Cases Spread Globally
A new COVID-19 variant, known as BA.3.2 and nicknamed “Cicada,” is drawing increased scrutiny from scientists as it spreads across multiple countries. The strain, first identified in South Africa in 2024, has now been detected in more than 20 countries and is circulating in at least 25 U.S. states, according to the Centers for Disease Control and Prevention. Experts say the variant stands out due to an unusually high number of mutations—around 70 to 75—in its spike protein, raising concerns about increased transmissibility and immune evasion.
Researchers, including Andrew Pekosz, note that while the virus that causes COVID-19 continues to evolve naturally, BA.3.2 appears more genetically distinct than many recent variants. The nickname “Cicada” reflects its pattern of remaining under the radar before reemerging more prominently. Despite these mutations, specialists say existing vaccines are still expected to provide protection against severe illness, even if their effectiveness at preventing infection may be reduced.
Symptoms linked to the variant remain similar to earlier strains, including fever, cough, fatigue, sore throat, and loss of taste or smell. Medical experts, such as Kyle B. Enfield, emphasize that there is currently no clear evidence the variant causes more severe disease. However, social media users who say they contracted the strain have described intense symptoms, including high fevers and prolonged fatigue. Health officials continue to advise caution, urging people to stay home when sick and rely on vaccination to reduce the risk of serious outcomes.
