Dengue fever is a serious viral infection transmitted to humans through the bite of an infected Aedes mosquito. It represents a major public health challenge, particularly in tropical and sub-tropical regions like Southeast Asia. In Vietnam, dengue outbreaks are common, especially during the rainy season. Therefore, understanding this disease and knowing how to prevent it are essential skills for every family to protect its members and the wider community.

When a person is infected, the first symptoms usually appear after 4 to 10 days. These often include a high fever, severe headache, pain behind the eyes, muscle and joint pains, and a skin rash. While many people recover within a week or so, dengue can sometimes become severe, leading to a dangerous condition called dengue hemorrhagic fever. This makes early detection and proper care very important for patients.

The most effective way to prevent dengue is to stop mosquitoes from breeding. The Aedes mosquito lays its eggs in standing water. These breeding grounds can be found in and around our homes in places like flower pots, old tires, and water storage containers. To control the mosquito population, we must eliminate these sources of standing water. Regularly checking and cleaning these areas can significantly reduce the risk of dengue transmission in our neighborhoods.

In addition to managing breeding sites, taking personal protective measures is also crucial. This includes wearing long-sleeved clothing, using mosquito repellent on exposed skin, and sleeping under a mosquito net, especially during the day when Aedes mosquitoes are most active. By taking these simple but effective steps, we can all contribute to creating a safer, dengue-free environment for ourselves and our families.
