NHS hospitals are experiencing an unprecedented surge in "superflu" cases, primarily attributed to the H3N2 strain, also known as subclade K. This has led to patients being treated in makeshift spaces like cupboards and waiting rooms due to a severe lack of hospital capacity. The flu season started earlier than usual, and cases are not expected to peak before Christmas, potentially affecting thousands more. Data indicates that as of the past week, 2,260 patients were admitted to hospitals with the flu, with predictions suggesting up to 8,000 patients in England could be hospitalized with the virus by the end of the week, far exceeding the previous record of 5,400.
Doctors are urging the public, especially vulnerable groups such as the elderly, young children, and individuals with disabilities, to get their flu vaccines as a "last chance" for protection before the holiday period. Pharmacies are reporting that flu vaccine stock is running low due to high demand, despite reassurances from the UK Health Security Agency (UKHSA) that sufficient vaccines are available. The H3N2 strain is characterized by harsher symptoms and rapid spread, contributing to the strain on healthcare services, with schools also identified as superspreader locations. The UKHSA has issued an urgent warning to get vaccinated before Christmas to protect oneself and others.
