The UK Health Security Agency (UKHSA) detected invasive Aedes aegypti mosquitoes and larvae at residential properties in east London. ^[1] The UK Health Security Agency reported 6,069 lab-confirmed cases of giardiasis in England in 2025, representing an 11.4% rise from 2024. ^[2] The study found that passive data collected by the Sleep Cycle app can provide a robust and regionally consistent indicator of community respiratory illness while also providing early signals for influenza and COVID-19 activity. ^[3] The UK Health Security Agency (UKHSA) and Sleep Cycle published the results of a research study evaluating if cough data from a sleep app could give early indications of increasing respiratory illness in England. ^[4] This is the first time Aedes aegypti has been identified breeding in the UK, though it is the fourth time this species has been detected in the UK in recent years. ^[5] The reported cases of giardiasis in England in 2025 represent the highest yearly total in almost a decade. ^[6] The rise in giardiasis cases is likely due to increased international travel in the post-pandemic era, upgrades to lab testing, changes in rainfall and flooding, and better awareness of Giardia duodenalis. ^[7] Giardia duodenalis is a tiny parasite that infects the small intestine and is one of the most common parasitic causes of diarrhea globally. ^[8]
