Los Angeles County Faces Unprecedented Local Dengue Transmission, Health Officials Ramp Up ResponseSource: Google Street View

The Los Angeles County Department of Public Health is currently investigating an additional case of locally-acquired dengue in Panorama City. The infected local resident, who hadn't left for areas where dengue is typically found, represents another instance in the unusual transmission pattern of this mosquito-borne illness within the county's limits. According to a recent bulletin, this brings 2024's count of local dengue infections in Los Angeles County to four, a situation public health officials are watching with increasing concern.

While instances of locally-transmitted dengue are still rare in LA County, officials are urging residents to take proactive steps against the spread. These measures involve wearing mosquito repellent, ensuring homes are sealed against mosquito entry, and preventing conditions conducive to mosquito breeding. The county health department detailed specific recommendations, like draining standing water and regularly checking screens for tears or holes. "We are seeing the local transmission of dengue, which is unprecedented in Los Angeles County," Los Angeles County Health Officer Muntu Davis, MD, MPH conveyed in a statement. "Preventing mosquito bites and mosquito breeding is the best way stop the ongoing local transmission of dengue."

Public health officials are not taking these developments lightly, collaborating with the Greater Los Angeles County Vector Control District to lay down an aggressive strategy that includes heightened surveillance and targeted community outreach. The District Manager, Susanne Kluh, confirmed the implementation of rigorous control measures, such as mosquito trapping and expansive spraying operations. "The District will continue its surveillance and control efforts, including additional property inspections, as well as backpack and truck-mounted mosquito treatments," Kluh emphasized in a public communication.

Aedes mosquitoes, the primary vectors for the dengue virus, are prevalent in LA County, however, they have not historically been leading to local dengue transmissions; most cases up until this point were associated with international travel to endemic regions. The virus manifests with flu-like symptoms and can escalate to more severe health issues if not properly addressed. Public Health is advising healthcare providers to sensitize patients about fever prevention and report suspected cases of dengue fever.
