Over the course of 16 months, more than 35400 cases of Zika virus infection have been confirmed in Puerto Rico. This represents 85% of all cases reported in the USA and its territories. The Zika epidemic is exposing the profound failure of socioeconomic policies, as well as the failure to protect sexual and reproductive health rights in Puerto Rico. Considering the high poverty rates, high levels of sexuality-related stigma, poor quality sex education, limited access to contraception, and limited participation in the allocation of resources for prevention, it is unreasonable to focus public health efforts to prevent Zika virus infection on vector control. The allocation and equitable management of resources for research and intervention are required in order to understand and address the barriers to and facilitators of prevention at the individual, social, and structural levels. Further, the impact of efforts to tackle the social determinants of the Zika virus epidemic on the island should be assessed.

The knowledge on the life cycle of flaviviruses is still incomplete, and no direct-acting antivirals against their infections are clinically available. Herein, by screening via a Zika virus (ZIKV) replicon assay, we found that the N-terminus of NS2A exhibited great tolerance to the insertions of different split fluorescent proteins (split-FPs). Furthermore, both ZIKV and dengue virus encoding a split-FP-tagged NS2A propagated efficiently, and the split-FP-tagged ZIKVs had good genetic stability.

Mosquito-borne flaviviruses represent a public health challenge due to the high-rate endemic infections, severe clinical outcomes, and the potential risk of emerging global outbreaks. Flavivirus disease pathogenesis converges on cellular factors from vectors and hosts, and their interactions are still unclear. Exosomes and microparticles are extracellular vesicles released from cells that mediate the intercellular communication necessary for maintaining homeostasis; however, they have been shown to be involved in disease establishment and progression.

Background: Prenatally transmitted viruses can cause severe damage to the developing brain. There is unexplained variability in prenatal brain injury and postnatal neurodevelopmental outcomes, suggesting disease modifiers. Of note, prenatal Zika infection can cause a spectrum of neurodevelopmental disorders, including congenital Zika syndrome.

Flaviviruses utilize the cellular endoplasmic reticulum (ER) for all aspects of their lifecycle. Genome replication and other viral activities take place in structures called replication organelles (ROs), which are invaginations induced in the ER membrane. Among the required elements for RO formation is the biogenesis of viral nonstructural proteins NS4A and NS4B.
