## Abstract

PROJECT SUMMARY
 The impact of infections transmitted by mosquitoes is global. Arboviral diseases such as dengue,
chikungunya, and Zika are a significant health concern due to the expanding geographical range of many
mosquito species. Emphasis on disease surveillance systems is central to evaluate the effectiveness of primary
and secondary dengue prevention methods and strategies, including the introduction of dengue vaccines and
new vector control methods. In the current application, the study team will address specific and fundamental
gaps in the diagnosis and clinical management of dengue and other acute febrile illnesses (AFI); ultimately,
evaluating the efficacy of vector control strategies in reducing the incidence of arbovirus infection through a
combination of both clinic- and community-based surveillance systems. The study team’s long-term goal is to
mitigate arboviral and other AFI disease burdens by improving diagnosis, clinical management, and prevention
strategies. The study’s central hypothesis is that arbovirus infections and AFI disease surveillance, through the
continuation of SEDSS and COPA, will promote evidence-driven public health policy decisions and reduce the
burden of disease. The rationale for the current study is that understanding the etiology, epidemiology, and
severity of arboviral diseases will allow the United States to be better prepared and respond to critical vector-
borne disease outbreaks. The study team will test the central hypothesis by pursuing two specific aims: 1)
Explore the natural history of dengue and arboviral infections and other acute febrile illnesses in their differential
diagnosis to understand their epidemiology, spectrum of disease, and outcomes to provide recommendations
for diagnosis and clinical management, and; 2) Define the correlates of risk and protection of arbovirus
transmission in the setting of vector-reduction strategies. Under Specific Aim 1, the team will strengthen hospital
surveillance of acute febrile illness (AFI) and maintain an AFI platform for conducting clinical research. For
Specific Aim 2, the team will maintain a community-based cohort to assess the incidence and prevalence of
arboviral infection, as well as, evaluate the incidence, prevalence, and etiology of other AFIs in selected
communities. Central to both aims is the establishment of a data management system and the continuation of
strengthening collaborations with the local government, community leaders, and other stakeholders to ensure
continuity of the established program. The proposed research is significant because it is expected to deliver
robust and broad knowledge regarding the epidemiologic patterns of common arboviral diseases in the context
of other AFI of the present and those that may emerge in the geographical setting. Such results provide evidence-
based responses to critical questions regarding dengue (and other arboviruses) diagnosis, immune response,
and clinical management. Also, the community...
