GLENDALE, Calif. (KABC) -- Los Angeles County is seeing a rise in West Nile virus cases, and many of the people infected live in the San Fernando Valley.
So far in 2017, 22 people have tested positive county-wide -- that's higher than the average over the past five years.
Nearly half of those cases are in the Valley, where county officials also found 49 infected mosquito samples just last week.
People living in all parts of the county are urged to wear insect repellent while outdoors and stay away from standing water.
