BA.3.2 COVID-19 Variant Spreads Globally

A new COVID-19 variant, BA.3.2, informally known as the 'cicada' strain, first identified in South Africa in November 2024, is now spreading rapidly across multiple continents, including the United States and United Kingdom. The United States — Centers for Disease Control and Prevention reports its presence in at least 23 countries, with significant increases in detections between November 2025 and January 2026 in countries like Denmark, Germany, and the Netherlands. While there is no evidence of increased severity, the BA.3.2 variant carries 70 to 75 genetic changes in its spike protein, which may allow it to evade existing immunity and reduce the effectiveness of current vaccines. The Global Virus Network is monitoring the variant but emphasizes no cause for alarm, advocating for sustained genomic surveillance and public health vigilance. Experts like Emily Ronay Johnston highlight the potential for a spike in cases due to immune evasion, underscoring the importance of continued precautions and potential vaccine updates.
