As Europe reels from heatwaves and wildfires, rising temperatures have also raised concerns about the spread of viruses that are not generally found in cooler climates. The World Health Organization (WHO) has issued an alert for Crimean-Congo hemorrhagic fever (CCHF), a tick-borne infection with a high mortality rate. CCHF is endemic in Africa, the Balkans, the Middle East and parts of Asia. The first fatal case in Europe was in Spain in 2016. According to Horizon, which publishes articles on research funded by the European Union, “Scientists are now warning that CCHF, which can kill 10 to 40 million people, is spreading north and west across Europe.” (Desk Explained)
