India has reported a mild resurgence in COVID-19 cases, with 257 active infections recorded nationwide as of May 21, 2025. Southern states continue to report the highest numbers, with Kerala topping the chart with 95 cases, followed by Tamil Nadu (66) and Maharashtra (56).
Mild Rise in Cases Across India, Kerala Reports Most Infections
The recent uptick is primarily attributed to the spread of the Omicron subvariant JN.1 and its offshoots, LF.7 and NB.1.8. However, health authorities have confirmed that the situation remains under control. According to a central review meeting held by the Ministry of Health, involving ICMR and NCDC experts, the majority of reported cases are mild and do not require hospitalization.
Under control situation; Experts link rise to humidity, travel and waning immunity
Doctors believe the spike is likely due to waning immunity, increased interstate travel, and humid weather conditions, especially in Kerala. While the rise in infections is being closely monitored, no significant increase in hospitalization or severe illness has been reported.
Health officials have urged citizens to continue following precautionary measures—wearing masks in crowded places, practicing hand hygiene, and ensuring high-risk individuals stay up-to-date with vaccinations.
Globally, similar trends have been observed in Singapore, Hong Kong, and Thailand. With the virus still evolving, the public is advised to stay cautious and avoid complacency, especially as newer subvariants begin to circulate.
In addition to preventive steps, state governments have been advised to increase testing in symptomatic individuals and resume genome sequencing of positive samples to track emerging variants. The health ministry also emphasized the importance of community awareness campaigns, especially in rural areas. Experts reiterate that while the current rise isn’t alarming, proactive surveillance is key to avoiding any future surge or public health burden.
