health π€§ H1N1 surge in Delhi-NCR: Here's the lowdown
Delhi-NCR is facing a surge in H1N1 cases because the virus is mutating, making it more infectious. Dr Randeep Guleria explained this, noting the city has hit 1,777 confirmed cases this year. This antigenic drift allows the virus to partially evade immunity from past exposure or vaccines. Monsoon conditions are also helping the virus survive longer in the atmosphere, fueling the spread. Basic infection control measures are advised as the case numbers are expected to gradually decrease.
