A rare parasitic infection known as raccoon roundworm has been confirmed in Los Angeles. The infection, Baylisascaris procyonis, can affect the brain, spinal cord and eyes.

Los Angeles health officials announced they are investigating a handful of locally acquired dengue fever cases in the city of Baldwin Park.

“Dengue is primarily transmitted through the bite of an infected Aedes mosquito. Although Aedes mosquitoes are common in LA County, cases of locally acquired dengue are extremely rare,” Los Angeles County Public Health Director Barbara Ferrer said Wednesday.
