Two more mosquitoes in Plano have tested positive for West Nile virus, prompting spraying in two south Plano neighborhoods.

A mosquito in the city of Plano has tested positive for West Nile virus, the city announced four days after officials were informed that a Plano resident had contracted the same disease.

The city plans to spray for mosquitoes starting at 9 p.m. Thursday near where the mosquito was captured in neighborhoods south of Parker Road on both sides of Alma Drive, city spokesman Steve Stoler said Monday in a statement.

This is the first instance in 2017 of a Plano mosquito testing positive for West Nile virus. Before the human case was announced late last week, Stoler said, the city's regular mosquito trapping and testing program had not yet identified a positive case.

The city is also spraying an area near Hickey Elementary School beginning 9 p.m. Monday, a move that was announced when the human case was made public.

Residents near the spray areas should ensure pets and children are safely indoors while crews treat the neighborhoods for mosquitoes.
