First Locally Acquired Dengue Case Detected in San Bernardino County
San Bernardino County has reported its first locally acquired case of dengue fever, a mosquito-borne illness, in the city of San Bernardino. The identity of the patient has not been disclosed, and health officials are still investigating how the infection occurred.
Typically, dengue cases in the county are linked to travel in regions where the virus is more prevalent. However, the appearance of a locally acquired case suggests that infected Aedes mosquitoes are present in the area and capable of spreading the virus.
What is Dengue Fever?
Dengue fever is transmitted through the bite of an infected Aedes mosquito. If a mosquito bites a person who has the virus in their blood, it becomes infected and can spread the virus to others through subsequent bites. While many individuals bitten by an infected mosquito may not experience symptoms, those who do may suffer from fever, nausea, vomiting, rash, and severe aches and pains, particularly behind the eyes and in the muscles and joints. Most recover within two weeks, but it is crucial to seek medical attention if symptoms develop.
San Bernardino County Health Officer, Dr. Michael A. Sequeira, emphasized the importance of prevention: “Dengue can cause serious illness in humans. I urge residents to take precautions to protect themselves against mosquito bites.”
How to Protect Yourself from Mosquitoes:
- Dump, Drain, and Scrub: Eliminate standing water from containers around your home. Aedes mosquitoes can lay eggs in places like plant saucers, lawn drains, and pet dishes. Scrubbing containers removes eggs clinging to surfaces.
- Dress Properly Outdoors: Wear long-sleeved shirts, pants, socks, and shoes. Light-colored, loose-fitting clothing is most effective.
- Use Insect Repellent: Choose a repellent containing DEET, Picaridin, IR3535, or oil of lemon eucalyptus, and apply as directed.
- Secure Your Home: Ensure that windows and doors have well-maintained screens to keep mosquitoes out.
As the weather cools, mosquitoes remain active, so it is essential to stay vigilant.
