Los Angeles Grapples With Four Local Dengue Cases in Two Weeks

Los Angeles County public health authorities are dealing with a fourth case of dengue reported in just over two weeks, as evidence mounts that the mosquito-borne infection is circulating in the area for the first time.

None of the four patients recently traveled to areas where dengue regularly occurs, suggesting the virus is spreading locally via infected mosquitoes, the Los Angeles County Department of Public Health said in a statement. The infection disclosed Wednesday isn’t related to a cluster of three cases announced earlier this month, officials said.
