Every year from June to October is peak dengue fever season in Taiwan. High temperatures combined with rainfall greatly increase vector mosquito activity. Dengue is mainly transmitted by Aedes aegypti and Aedes albopictus. These mosquitoes prefer to breed in dark, damp places with standing water such as plant saucers, plastic containers, depressions in tarps, discarded tires, and similar locations. As long as there is standing water, it can become a breeding ground for vector mosquitoes, increasing the risk of dengue transmission.

The key to dengue prevention lies in blocking mosquito breeding in everyday life by implementing the four preventive actions: “inspect, empty, clean, and scrub.” Inspect homes and surrounding areas, empty containers holding standing water, clean drains and various containers, and scrub inner surfaces to prevent mosquito eggs from adhering. When going out, it is recommended to wear light-colored long-sleeved clothing and use insect repellent to reduce the chance of bites.

If symptoms such as high fever, muscle and joint pain, pain behind the eyes, or rashes appear, seek medical attention immediately and cooperate with health authorities in epidemiological investigations. After a confirmed diagnosis, be sure to carry out a thorough environmental cleanup in and around the home: remove all containers with standing water, clear drains, and properly seal or dispose of waste to prevent the breeding of new vector mosquitoes and stop the spread of the virus within the community.

Preventing dengue fever is not difficult, but it requires daily effort from everyone. Regularly check balconies, yards, and community areas for standing water, remove or empty containers that could become breeding sources, and keep the environment dry. The administration continues to work with local governments to strengthen breeding-site inspections, environmental cleanup, and community outreach, making “no standing water, no larvae; no larvae, no mosquitoes; no mosquitoes, no dengue” a shared habit and consensus, together safeguarding a healthy and safe living environment.
