How climate change drives the return of deadly diseases

We never thought we’d see it. But Malaria is making a comeback in the British Isles [1] According to the latest findings from the UK Health Security Agency(UKHSA) cases rose by a whopping 32% from 2022 to 2023 making them the highest in 20 years. More than 2000 cases in fact. Now some of this is due no doubt to travel bounce backs after the COVID 19 pandemic. But once put into a broader context. the real pattern becomes both clear and alarming. Global warming is driving a massive spread of insect vector diseases. Dangerous diseases that almost seemed under control until the oil companies unleashed climate change on an innocent world

Staying with Britain just for now, William Hunter of the Mail [2] reports on the appearance of two deadly mosquitoes in the UK: the Egyptian mosquito Aedes aegypti and the appropriately named Tiger mosquito Aedes albopictus. For now these are isolated events, and under current conditions their spread may even be containable. But every year the climate gets a little warmer. Every year brings a higher chance that these vectors will spread their deadly triple load: Dengue Fever, Chikungunya and Zika. With all the consequences which wel- seasoned readers of this blog will recall from our earlier outings on this theme (see LSS 25 3 25, 25 10 21 and many others)

We confess to becoming a little angry when we we write stories like this: such disasters could have been so avoidable. Once, not so long ago these diseases were unknown in this islands except as travellers’ tales, or as the province of medical specialists. Now a wave is crossing the world. We know what the remedy is. If by any chance you are a parent reading these lines: this story is one more line of evidence among many. Your children can never be truly safe until global warming is finally controlled and reversed.
