* Data are provisional and subject to change; counts reflect confirmed and probable cases in residents of Mohave County only; Counts are based on date reported to MCDPH, not necessarily date of infection.
**The 5-year median is calculated using counts from this same time period in the years 2018 - 2022. Covid-19 is a 3-yr median.
Mosquito activity
• We have fogged (pesticides applied for adult mosquito control) in Mohave Valley twice this season due to high mosquito counts and nuisance complaints.
• To date this season, no mosquitos trapped in Mohave County have tested positive for West Nile virus, although La Paz County did have a positive mosquito pool trapped on the border with Mohave County.
• Aedes aegypti mosquitos have been identified for the first time in Mohave County.
Rabies
The epizootic of gray fox rabies virus infection in wild animals in and around the Hualapai Mountains area continues. In late May there were two incidents of significance. In one, a family dog was attacked by a fox whilst chained in the yard of its residence. The grey fox was killed and tested positive for rabies at the Arizona State Public Health Laboratory. The second incident occurred several days later when another dog was attacked by a wild fox or coyote whilst in a neighborhood yard. The fox/coyote could not be located for testing.
Salmonellosis cluster
The AZDHS (Arizona Department of Health Services) is assisting MCDPH (Mohave County Department of Public Health) with investigating a small cluster of Salmonella Braenderup infection in three Mohave County residents. All affected are adult women and were ill in May and June; one required hospitalization. Additional highly related cases have been identified in California and Nevada. At present, no source exposure has been identified, and no additional cases have been identified in the past several weeks.
