Several new mosquito samples collected and tested last week have been identified as carriers for the West Nile virus, according to York County officials.

Samples taken in Spring Garden Township, Manchester Township, York City, West Manchester Township and Springettsbury Township have all come back positive, according to a news release issued Thursday.

The state Department of Environmental Protection will be performing additional mosquito surveillance, sampling and larval control in those municipalities. 

Samples in Spring Garden and Manchester townships were collected on Sept. 9, and positive samples in York City and West Manchester and Springettsbury townships were collected on Sept. 10, according to the release.

Scientists believe the species originated in Africa but came to the Americas on slave ships. It has continued to spread through shipping and airplanes. Now it's found through much of the world.
