Singapore is managing a new COVID-19 wave that pushed weekly infections to 12,700 in the week of May 10 to 16, 2026 — a jump of nearly 60% from 8,000 cases the week prior, according to Singapore's Communicable Diseases Agency (CDA).
The surge is being driven by NB.1.8.1, a descendant of the JN.1 Omicron lineage now accounting for more than half of all locally sequenced COVID-19 cases in the city-state. Simultaneously, data from the World Health Organization's Western Pacific Regional Office shows Singapore posted the region's highest combined influenza and SARS-CoV-2 positivity rate at 17% during epidemiological week 21 — making it both a COVID and flu concern heading into June.
