A newly identified COVID-19 variant, informally known as 'Cicada', has been detected in the United Kingdom as health authorities continue to track its spread across multiple regions. The strain, first identified in South Africa in late 2024, has now been reported in at least 23 countries, according to the US Centers for Disease Control and Prevention (CDC).
Detections began rising more noticeably in late 2025, with cases recorded across Europe, North America, Asia and parts of Africa. UK health officials say overall COVID-19 activity remains stable, with existing vaccines and treatments continuing to provide protection against serious outcomes.
