Tracking dengue transmission in Nha Trang
In 2015, our Vietnamese team began preparing for the next stage of our research in Nha Trang. This involved monitoring the mosquito population, collating data on dengue prevalence throughout the city and actively talking to the community at local meetings and events.
Our team has met with leaders and community representatives from each of the 27 wards across the city, and we’ve been encouraged by their initial support for our research. We will continue to meet with city and provincial leaders in the second half of 2016 to further explain our research and seek their acceptance of our approach.
We are also working with the Department of Health and the Department of Education and Training to learn more about the spread of dengue in Nha Trang. We are commencing work with schools and families in a small number of communities to measure how and when children get dengue. We will also continue collating historical dengue data from local hospitals, health clinics and government departments to help us understand year-to-year variations in dengue transmission across different parts of the city.
We’re hoping this information will help us to find the best way to work with existing health systems to enhance dengue surveillance across the city. Effectively tracking the transmission of dengue will help us evaluate the impact of our method, which we hope to trial across Nha Trang in the future.
Our team is also continuing to monitor the levels of Wolbachia in the Aedes aegypti mosquito population on nearby Tri Nguyen Island, where we carried out releases of Wolbachia mosquitoes in 2014.
