As South and Central American countries prepare for increased birth defects from Zika virus outbreaks and plan for mitigation strategies to minimize ongoing and future outbreaks, understanding important characteristics of Zika outbreaks and how they vary across regions is a challenging and important problem. We developed a mathematical model for the 2015/2016 Zika virus outbreak dynamics in Colombia, El Salvador, and Suriname. We fit the model to publicly available data provided by the Pan… Expand
Leveraging multiple data types to estimate the true size of the Zika epidemic in the Americas
Since the first Zika virus (ZIKV) infection was confirmed in Brazil in May 2015, several hundred thousand cases have been reported across the Americas. This figure gives an incomplete picture of theExpand
Projecting the end of the Zika virus epidemic in Latin America: a modelling analysis
TLDR
The ZIKV epidemic is by and large over, with incidence projected to be low in most cities in LAC in 2018 and the estimated rate of infection suggests that most cities have a population with high levels of herd immunity. Expand
Projecting the end of the Zika virus epidemic in Latin America: a modelling analysis
TLDR
It is suggested that the ZIKV epidemic is by and large over within LAC, with incidence projected to be low in most cities in 2018 and the estimated rate of infection suggests that most cities have a population with high levels of herd immunity. Expand
Leveraging multiple data types to estimate the size of the Zika epidemic in the Americas
TLDR
These estimates represent the most extensive attempt to determine the size of the Zika epidemic in the Americas, offering a baseline for assessing the risk of future Zika epidemics in this region. Expand
Reviewing estimates of the basic reproduction number for dengue, Zika and chikungunya across global climate zones.
TLDR
Climate zone is indicated to be an important determinant of the basic reproduction number, R0, for dengue, Zika virus, and chikungunya, and the results suggest that R0 may increase in temperate regions in response to global warming, and highlight the increasing need for strengthening preparedness and control activities. Expand
Approximate Bayesian algorithm to estimate the basic reproduction number in an influenza pandemic using arrival times of imported cases.
TLDR
An Approximate Bayesian Computation algorithm is developed to estimate the basic reproduction number (R0) in addition to the reporting rate and unobserved epidemic start time, utilizing travel, and routine surveillance data in an influenza pandemic. Expand
What lies beneath: a spatial mosaic of Zika virus transmission in the 2015-2016 epidemic in Colombia
Background: Temporal incidence patterns provide a crucial window into the dynamics of emerging infectious diseases, yet their utility is limited by the spatially aggregated form in which they areExpand
A modified Susceptible-Infected-Recovered model for observed under-reported incidence data.
TLDR
A stochastic model for the conditional distribution of current disease incidence given the entire past history of incidences is developed, which results in an epidemic model that can track complex epidemic dynamics, such as outbreaks with multiple waves. Expand
Measuring the global burden of chikungunya and Zika viruses: A systematic review
TLDR
Evaluating the global burden caused by CHIKV and ZIKV between 2010 and 2019 suggests that transmission-blocking strategies, including vector control and vaccine development, remain crucial priorities in reducing global disease burden through prevention of potentially devastating arboviral outbreaks. Expand
Effects of multiple transmission pathways on Zika dynamics
Although the Zika virus is transmitted to humans primarily through the bite of infected female Aedes aegypti mosquitoes, it can also be sexually and vertically transmitted within both populations. InExpand

TLDR
It would take 12–20 years before there are a sufficient number of susceptible individuals for ZIKV to re-emerge, which is on the same timescale as the circulation of dengue virus serotypes in the region. Expand
Estimate of the reproduction number of the 2015 Zika virus outbreak in Barranquilla, Colombia, and estimation of the relative role of sexual transmission.
TLDR
The R0 of the 2015 ZIKV outbreak in Barranquilla, Colombia, is estimated through an analysis of the exponential rise in clinically identified ZikV cases, among the first estimates of R0 for a ZIKv outbreak in the Americas, and the first quantifications of the relative impact of sexual transmission.

Transmission potential of Zika virus infection in the South Pacific.
TLDR
The transmissibility of Zika virus infection appears to be comparable to those of dengue and chikungunya viruses, and this finding indicates that Zika virus replication within the vector is perhaps comparable to d Dengue and Chikung unya. Expand
Model-based projections of Zika virus infections in childbearing women in the Americas
TLDR
A new approach that combines classic results from epidemiological theory with seroprevalence data and highly spatially resolved data about drivers of transmission to make location-specific projections of epidemic attack rates constitutes a revised upper limit of populations at risk in the current Zika epidemic.

J un 2 01 6 Estimation of the reproduction number of the 2015 Zika virus outbreak in Barranquilla , Colombia , and a first estimate of the relative role of sexual transmission
TLDR
This is among the first estimates of R0 for a ZIKV outbreak in the Americas, and the first quantification of the relative role of sexual transmission, and it finds sustained sexual transmission alone is unlikely. Expand
Comparative Analysis of Dengue and Zika Outbreaks Reveals Differences by Setting and Virus
TLDR
Compared three outbreaks of dengue and Zika virus in two different island settings in Micronesia, using a mathematical model of transmission dynamics and making full use of commonalities in disease and setting between the outbreaks, it is found that the estimated reproduction numbers for Zika and d Dengue were similar when considered in the same setting, but that, conversely, reproduction number for the same disease can vary considerably by setting.

The results suggest that the Zika outbreak in Rio de Janeiro emerged due to population susceptibility and ubiquitous presence of Ae. Expand

TLDR
The estimated R0 from Colombia supports the observed rapid spread of Zika virus disease (ZVD), which is ongoing in the Americas and occurred in all age groups with highest rates in 20 to 49 year-olds. Expand
Times to Key Events in the Course of Zika Infection and their Implications for Surveillance: A Systematic Review and Pooled Analysis
TLDR
Symptom or antibody-based surveillance can do little to reduce the risk of Zika contaminated blood donations, and high incidence areas may consider PCR testing to identify lots safe for use in pregnant women. Expand
