Overview

• Italy's West Nile cases rose from 32 to 89 in a week, with infections now reported in 31 provinces as the outbreak spreads from the Pianura Padana to new foci in Latina and Caserta.
• Experts estimate at least 10 000 infections across Italy, most asymptomatic, while 40 confirmed patients have developed neuro-invasive disease with a 20% fatality rate among those severe cases.
• Regional authorities, led by Lazio's governor, have issued emergency ordinances and earmarked €1 million for mosquito disinfestation and habitat control.
• Integrated surveillance networks in Lazio, Campania and Lombardy now include expanded mosquito trapping, animal health monitoring and mandatory blood-donation screening in affected areas.
• Health officials recommend DEET-, icaridin- or PMD-based repellents, long sleeves, light clothing, fragrance avoidance and window screens to reduce mosquito bites.
