As of 13 June 2026, Malaysia reported 33'367 dengue cases, a 27% increase compared with the same period in 2025. The highest burden was recorded in Selangor (15'422 cases), followed by Kuala Lumpur/Putrajaya (6'107) and Johor (3'556). Sabah experienced the sharpest rise, with cases increasing by 50% to 2'866. Twenty-three deaths were reported, up from 17 during the same period last year.
Health authorities attribute the increase to the expected cyclical dengue pattern and the emergence of DENV-3 as the dominant serotype. In response, the Ministry of Health has strengthened prevention efforts through its Dengue-Free Community (Kombat) program.
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 6 years of age who have already contracted dengue; see the ECTM statement.
In case of fever:
- Make sure you hydrate enough and take paracetamol medication to relieve symptoms.
- 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.
