Recent clinical and experimental evidences support immunological cross-reactivity between dengue and Zika. In particular, these evidences show that plasma to dengue was able to drive antibody-dependent enhancement of Zika infection. Co-circulation of multiple serotypes of dengue and dengue-Zika co-circulation have previously been reported in refs. In particular, co-infection of dengue and Zika were observed in two patients during the Zika outbreak in New Caledonia in 2014, and in two patients during the Zika outbreak in Tuparetama of Brazil in 2015. The co-circulation could be a potentially series public concern given that more than a third of the world’s population lives in countries where dengue is endemic, with the dengue belt covering Central America, most of South America, sub-Saharan Africa, India, and South East Asia. Relevant to this co-infection is the development of vaccine products against dengue by Sanofi Pasteur, and the clinical trials by Butantan and Takeda. Thus, it is an important urgent issue for public health decision makers to know how dengue immunization program impacts Zika transmission when co-circulation becomes wide spread. Specially, under which conditions implemented dengue immunization control programs may boost the outbreak of Zika is no longer a thought-provoking issue. Developing a framework to address this issue through a mathematical model is the main objective of this study.
