Dallas County released an update on West Nile Virus Friday afternoon.
Health officials say the number of human cases is holding steady at two, but that won't stop the spraying plans for Friday night.
In Central Dallas, trucks will target east of the tollway and south of Overdowns Drive.
A mosquito trap tested positive for West Nile on Lakehurst recently.
Highland Park will also be spraying. They will spray everywhere except the area south of Belclaire Avenue and west of Preston Road.
