Mumbai, May 22 (UNI) The Brihanmumbai Municipal Corporation (BMC) has intensified surveillance and monitoring of COVID-19 patients as Mumbai experiences a surge in cases, coinciding with the emergence of the JN.1 variant, an official said on Thursday.
According to sources, authorities continue to track influenza-like illnesses (ILI) and severe acute respiratory infections (SARI) alongside COVID-19, ensuring that suspected cases are promptly tested and positive patients receive treatment according to established protocols.
Genome sequencing efforts are ongoing to identify circulating viral variants, trace transmission patterns, and inform diagnostic and therapeutic strategies.
The BMC has confirmed that public health laboratories are equipped to carry out these analyses, while the Health department maintains vigilant oversight across Mumbai. Recent genomic data have revealed instances of co-infections involving H3N2 and other respiratory viruses. Additionally, the Death Audit Committee is reviewing mortality reports to assess any COVID-related fatalities.
Although the current number of active COVID-19 cases remains low and not alarming, continued genome sequencing is being conducted as a precautionary measure. Samples from Maharashtra are being sent to the National Institute of Virology (NIV) and B J Medical College in Pune for detailed analysis.
Mumbai’s COVID-19 case count has fluctuated over recent months, with one case each reported in January and February, none in March, four in April, and a notable increase to 120 cases in May. As of Wednesday (yesterday), 21,146 patients have recovered from the infection.
At the national level, India reported 257 active COVID-19 cases as of May 19. States such as Kerala, Maharashtra and Tamil Nadu have recorded the highest numbers, with Kerala reporting 69 cases, Maharashtra 44 and Tamil Nadu 34.
Other states including Karnataka, Gujarat, Delhi, Haryana, Rajasthan and Sikkim have also documented new infections.
KEM Hospital in Mumbai has confirmed two recent COVID-related deaths, raising localised concerns.
Health experts from the Indian Council of Medical Research (ICMR) and the National Centre for Disease Control (NCDC) emphasise that the overall situation in India remains manageable, with no indication of a significant resurgence. Enhanced monitoring, rapid case identification and response mechanisms are firmly in place.
The JN.1 variant, a sub-lineage of the Omicron variant, is characterised by an additional mutation in its spike protein, which facilitates viral entry into human cells. While it shares Omicron’s high transmissibility, illness duration varies from one to two weeks in mild to moderate cases, with severe infections potentially lasting longer. Some individuals remain asymptomatic despite infection.
Meanwhile, neighbouring regions such as Singapore and Hong Kong have reported rise in COVID-19 cases and fatalities linked to emerging Omicron subvariants, prompting health authorities to urge continued vigilance.
Experts caution against complacency and recommend adherence to preventive measures, especially in high-risk areas.
Despite the current low case numbers, ongoing surveillance, vaccination efforts, and public health precautions remain critical to preventing a new wave of infections.
Health officials advise the public to stay alert without panic, maintaining COVID-appropriate behaviour to safeguard community health.
