A resident of Baldwin Park, California, has been diagnosed with a locally acquired case of dengue fever, as confirmed by the Los Angeles County Department of Public Health. This marks the third case reported in California and the first in Los Angeles County, following cases in Pasadena and Long Beach in late 2023.
Understanding Dengue Fever
Dengue is the world’s most widespread insect-borne viral infection, transmitted primarily by Aedes mosquitoes. While it is more common in tropical and subtropical regions, mosquito species capable of spreading dengue exist in parts of the United States, including California.
“Los Angeles County, being a hub for international travel and trade, is inherently at risk for such cases,” said Dr. James Lawler, associate director at the Global Center for Health Security. Despite the recent case, public health officials assert that the risk of widespread transmission in Los Angeles County remains low, with no additional cases currently identified.
Rising Awareness and CDC Recommendations
The U.S. Centers for Disease Control and Prevention (CDC) recently issued an advisory highlighting the increased risk of dengue infections nationwide. Between January and June 2024, health officials identified 745 dengue cases in travellers returning from endemic regions.
The CDC urges clinicians to remain vigilant for symptoms of dengue, including fever, joint pain, severe headaches (often behind the eyes), and rashes. Severe cases may progress to life-threatening complications, requiring intensive care. Early detection is crucial, and testing options include RT-PCR and IgM antibody tests.
Preventative Measures
Local authorities recommend residents reduce mosquito exposure by:
- Eliminating standing water around homes.
- Ensuring window and door screens are intact.
- Wearing protective clothing and using insect repellents outdoors.
“Although locally acquired dengue is rare in the U.S., preventive measures are vital,” Dr. Lawler emphasized.
Impact of Public Health Efforts
Experts like Dr. Lawler point to declining public health resources as a factor in the resurgence of mosquito-borne diseases. “We’ve seen tremendous success in mosquito control over the past century, but recent trends suggest we’re losing ground,” he noted.
Public awareness and local government initiatives remain critical in curbing the spread of dengue and other mosquito-borne illnesses.
Symptoms and Recovery
Most people recover from dengue within 7 days, but approximately 1 in 20 may develop severe symptoms, including persistent vomiting, abdominal pain, or fluid accumulation. The Los Angeles County Department of Public Health advises residents to seek immediate medical care if these symptoms occur.
