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.

At least three cases of dengue fever have been reported in residents bitten by local mosquitoes in the Baldwin Park neighborhood east of downtown Los Angeles.

For the first time in California, health officials have reported a cluster of dengue fever cases that are not travel-related and warned residents to protect themselves from mosquito bites. Two more locally acquired cases of the mosquito-borne illness dengue have been detected in Baldwin Park residents,

There has been a rare uptick of the dengue virus in the US this year, with people being urged to look out for the symptoms. Los Angeles County has reported three locally acquired cases of dengue this year,

Health officials reported a single case of locally acquired dengue in Long Beach last year. Now, three such cases in Baldwin Park mark an unprecedented escalation.
