A new subvariant of the dominant Omicron variant, known as “Nimbus” (NB.1.8.1), has been detected in South and Southeast Asia and is circulating in many European countries. The European Centre for Disease Prevention and Control (ECDC) recommends boosters for at-risk groups or those working in high-risk settings. Testing is also recommended for people who are sick and have worsening symptoms.
Experts warn of an increase in COVID-19 infections in the coming months, citing low population immunity against SARS-CoV-2 in Europe. With vaccination rates varying by country and region, local factors play a significant role in determining disease severity. The ECDC has classified Nimbus as a Variant under Monitoring (VOM) due to two specific spike mutations that reduce human antibody neutralization and enhance viral evasion.
As the Northern Hemisphere emerges from its winter, experts are urging continued vigilance against COVID-19, emphasizing that the virus remains unpredictable and seasonal pathogen-like. With Bangladesh reporting deaths in June, China detecting new cases, and Singapore experiencing outbreaks, European authorities must remain watchful for potential increases in infections over the summer.
