Quick Summary

Dr Jolyon Medlock from the UK Health Security Agency warns that disease-carrying hyalomma ticks are surviving longer in the UK due to warmer temperatures. Historically unable to survive beyond nymph stage because of cooler climates, these ticks now sometimes reach adulthood during heatwaves, increasing their potential as carriers of Crimean-Congo haemorrhagic fever. While rare, this development is a growing concern for health officials tracking tick activity through surveillance schemes. Milder winters and hotter summers are also contributing to changes in the seasonal activity patterns of ticks more broadly across the UK.

Story summary

Disease-carrying ticks are surviving longer in the UK due to warmer temperatures, according to Dr. Jolyon Medlock of the UK Health Security Agency (UKHSA). Hyalomma ticks, which primarily transmit Crimean-Congo haemorrhagic fever, a severe and potentially fatal virus, were previously unable to survive into adulthood because it wasn't warm enough for them. However, hotter summers now allow these ticks to complete their life cycle from nymphs to adults. This shift means that health officials are starting to detect more instances of adult hyalomma ticks in the country, though they remain rare; historically, such cases have been documented fewer than five times over the last decade.
