Kerala urges boosters and masks as new Omicron variants spread, no school closures

Kerala is witnessing a rapid increase in COVID-19 cases, with the active caseload rising from 95 on May 19 to 430 by May 26, 2025. This surge is primarily driven by the Omicron subvariants NB.1.8.1 and LF.7, confirmed by genome sequencing from INSACOG and classified as Variants Under Monitoring by WHO.

Kerala Health Minister Veena George has called for intensified surveillance across all districts and emphasized early detection and self-care to manage the spread. Despite the rise, the symptoms remain "mild" with no serious complications reported, resembling cold or flu-like symptoms, according to medical experts.

The state accounts for over 40 percent of India's active COVID cases, with Maharashtra and Delhi trailing behind. Experts note that the increased transmissibility of these variants is due to their affinity for the upper respiratory tract, making them more contagious.

"No purpose is served by school closures," said officials, highlighting that children are not more vulnerable and schools do not amplify infections. Instead, vulnerable populations are urged to get booster shots and wear masks.

The surge is attributed to new birth cohorts without immunity and waning immunity among previously infected or vaccinated individuals. Enhanced diagnostics and public-private healthcare coordination remain critical for effective management.

"Kerala continues to report the highest number of active Covid cases in the country, accounting for over 40 percent of the total infections," underscoring the need for vigilance amid evolving variants.

This approach balances public health safety with minimal disruption, focusing on vaccination, masking, and surveillance rather than school closures.

Kerala faces a surge in COVID-19 cases driven by Omicron subvariants NB.1.8.1 and LF.7, with active infections rising to 430. Health Minister Veena George urges boosters and masks but rules out school closures, citing mild symptoms and no evidence of increased risk in children.
