How Does the Dengue Virus Work?
Let’s first examine how the dengue virus causes disease in humans.
The Dengue virus typically persists through horizontal transmission. The virus is transmitted into human body through infected female mosquitoes (primarily Aedes aegypti and Aedes albopictus).
However, in harsh conditions—such as a lack of human hosts or extreme weather—the virus can use vertical transmission (from mother mosquitoes to baby mosquitoes) to survive.
This survival tactic could make controlling dengue even more challenging, especially with climate change. As living environments and weather conditions shift dramatically, mosquito behaviors and ranges are becoming unpredictable. Global researchers emphasise the importance of expanding our knowledge about dengue virus in general and their transmission in particularly to develop better prevention strategies and more effective, efficient public health responses.
Why Did Collab Lab Choose This Project?
While the World Health Organization lists dengue fever among the top 10 serious global health threats, Vietnam faces the alarming complicated dengue situation. In recent years, we’ve faced two major dengue outbreaks, with a record 367,729 cases reported in 2022 alone, an all-time high.
Collab Lab’s mission is to make scientific publications more accessible and easier to understand. We prioritize projects relevant to public health in Vietnam, including common tropical infectious diseases, mental health, and climate change.
Given that dengue remains a top public health threat, Collab Lab has decided to animate research on vertical transmission in mosquitoes. Our goal is to spread knowledge and encourage the public to take more actions to protect themselves from dengue.
