As of 12 July 2026, Cambodia had reported 28'074 dengue cases and 38 deaths (case fatality rate: 0.1%), representing a 58.1% increase compared with the same period in 2025. Weekly case counts have remained above the epidemic threshold for most of the year, prompting the Ministry of Health to implement emergency vector control measures amid heavy rainfall, flooding, and El Niño-driven conditions that have intensified dengue transmission.
Prevention: Optimal protection against mosquitoes 24/7, including against other mosquito-borne diseases.
Vaccination: The Swiss Committee of Experts in Travel Medicine (ECMV) recommends vaccination with Qdenga® only for travellers over 4 years of age who have already contracted dengue; see the position paper of the ECTM.
In case of fever:
- Make sure you hydrate enough and take paracetamol medication to relieve symptoms.
- Malaria should be ruled out.
- Avoid taking medications containing acetylsalicylic acid (e.g., aspirin®), as this can increase the risk of bleeding in the event of a dengue infection. However, do not stop taking medications containing acetylsalicylic acid if they are already part of your regular treatment for an underlying. condition.
