Ohio Vectorborne Disease Surveillance Update
ODH staff set up traps to collect mosquitoes for surveillance.
The Ohio Department of Health (ODH) Zoonotic Disease Program, in partnership with ODH Laboratory, local public health partners and sanitary district partners, conducts statewide vectorborne disease surveillance which includes monitoring for human and veterinary cases.
We will monitor for diseases transmitted by mosquitoes and ticks throughout the summer and fall and will report positive results and summary statistics on this website, updated each Friday at noon. Please download the attached document for a more detailed summary of mosquito and tick surveillance in Ohio.
