The U.S. Centers for Disease Control and Prevention (CDC) is urging Americans to protect themselves from mosquito bites after West Nile virus activity reached its earliest and most widespread start in a decade.

As of June 30, health officials had confirmed at least 48 cases across 23 states, including 38 severe infections—well above the historical average of about 10 cases typically reported by the end of June.

Arizona has emerged as the nation's primary hotspot, with 32 reported infections, including 29 in Maricopa County.

Local health authorities have also linked four deaths to the virus this year, highlighting the increased risk posed by the disease during the summer months.

The CDC advises people spending time outdoors, particularly during Independence Day celebrations, to use insect repellents containing DEET, wear protective clothing, repair damaged window and door screens, and eliminate standing water around homes where mosquitoes can breed.

💡
While most people infected with West Nile virus experience mild or no symptoms, older adults and individuals with weakened immune systems face a greater risk of developing severe neurological complications.

Health officials say warmer temperatures and increased mosquito activity are contributing to the elevated transmission risk this season.
