The Los Angeles County Public Health Department has confirmed a case of locally acquired dengue from a resident who has no history of travel to areas where dengue fever is endemic. According to a release from the health department, the infected person resides in Baldwin Park.
It is the third case of locally acquired dengue in California and the first reported by the Los Angeles County Department of Public Health. Cases of locally acquired dengue were previously confirmed by Long Beach and Pasadena in fall 2023.
Prevention: Optimal mosquito bite protection 24/7, also in cities (during the day against dengue).
In case of fever, apply paracetamol products and hydration. If you have a fever, avoid taking medications containing acetylsalicylic acid (e.g., Aspirin®), as this can increase the risk of bleeding during a dengue infection. However, do not stop taking medications containing acetylsalicylic acid if it is already part of your regular treatment for an underlying condition.
Note on vaccination against dengue fever with Qdenga®:
The Swiss Expert Committee for Travel Medicine (ECTM) recommends a vaccination with Qdenga® only for travelers from 6 years old who have evidence of previous dengue infection and who will be exposed in a region with significant dengue transmission. For details, see ECTM Statement.
