The city of Fort Collins in Colorado is planning a second round of spraying to combat West Nile virus-infected mosquitoes. The decision comes after high numbers of infected mosquitoes were found in the northeast section of the city. The spraying will take place on Sunday, July 30, weather permitting. Residents are advised to stay indoors and keep doors and windows closed for 30 to 60 minutes after spraying to minimize pesticide exposure. Larimer County has reported the most cases of West Nile virus in humans in Colorado, with 1,012 cases since 2003.

Mosquitoes trapped in Anne Arundel County, Maryland, have tested positive for West Nile virus, marking the first identification of the virus in mosquitoes in the U.S. this year. No human cases have been reported. The Maryland Department of Agriculture will spray affected areas, and while the Environmental Protection Agency has deemed it safe, outdoor activity is advised against during spraying. The spraying is scheduled for July 23 near Crain Highway and Davidsonville Road. West Nile virus is transmitted through mosquito bites, with about 20% of those exposed developing symptoms such as headache, fever, and fatigue.
Larimer County, particularly Fort Collins, is experiencing a significant increase in the number of mosquitoes infected with West Nile virus (WNV) compared to last year. The high number of infected mosquitoes is concerning and unusual for this time of year. Larimer County uses a vector index to determine the threat of WNV, with an index above 0.5 indicating a strong likelihood of human cases. Currently, the vector indexes in various towns/cities in the county are above this threshold. Fort Collins will begin spraying for mosquitoes in response to the rising threat. The increase in infected mosquitoes is attributed to a wet spring followed by warm temperatures, creating ideal conditions for mosquito breeding. To reduce the risk of WNV, individuals are advised to eliminate standing water, use mosquito repellent, and avoid exposure during peak mosquito feeding times.
Workers will be spraying for mosquitoes in the Sonterra Community in Jarrell, Williamson County, due to the detection of West Nile virus in a trap location.

Symptoms of West Nile virus infection may include fever, headache, and body aches, and those age 50 and older and/or with compromised immune systems are at a higher risk for severe symptoms.
