The increase is attributed to rising temperatures and longer warm seasons, which create ideal conditions for mosquitoes to thrive and transmit the virus. Researchers at the Italian National Institute of Health note that these environmental changes have extended the transmission period, allowing the virus to circulate well into the fall.
