In 2014, Zika (ZIKV) emerged in the Pacific region and spread in the world. In early 2016, WHO declared the ZIKV outbreak an international public health emergency in connection with the severe neurological consequences observed following ZIKV infection. Since then, the number of countries reporting a Zika epidemic has steadily increased, illustrating that ZIKV’s geographic expansion is still ongoing, even in the region. In addition, the reappearance of ZIKV in the Federated States of Micronesia, Kosrea, 8 years after the Yap epidemic, illustrates the risk of outbreak’s recurrence in previously exposed areas.
The overall objective of this project is to identify the risk factors for the emergence and recurrence of Zika epidemics in the Pacific, with a particular focus on anti-Zika community immunity.
Characterization of the memory immune response against ZIKV – persistence and possible interference with dengue

Community mmunity against ZIKV – Status and Evolution in 4 Pacific sites

Epidemic dynamics of Zika – risk factors for epidemic emergence and recurrence

This project is expected to gather crucial information on the persistence of protective immunity against Zika virus in infected patients. It should also be used to assess the level of exposure and immunity of Pacific populations to the Zika virus.
