Rising temperatures and extended warm seasons in Italy are linked to an expanding spread of West Nile virus, as health officials report mosquitoes now transmit the disease over larger regions and for longer periods than before. The shift in climate patterns appears to be creating more favorable conditions for mosquito populations, increasing the risk of infection during months that were previously less affected. Experts are monitoring the trend closely as it may signal broader public health challenges tied to changing weather conditions.
Italian health authorities see evidence that rising temperatures and longer warm seasons are helping mosquitoes spread West Nile virus across a wider area, during more months of the year.
