Chikungunya fever (CHIKV), a viral disease transmitted by mosquitoes, is currently affecting several areas in the Caribbean. The vector is found in the Americas from southern Florida to Brazil, and the Caribbean is a highly connected region in terms of population movements. There is therefore a significant risk for the epidemic to quickly expand to a wide area in the Americas. Here, we describe the spread of CHIKV in the first three areas to report cases and between areas in the region. Local…

Mathematical modeling of Chikungunya fever control
The model shows the need to periodically evaluate the effectiveness of vector control measures, and according to the number of households in high risk areas, the goals of effective vector control to reduce the likelihood of mosquito-human transmission would be established.

Data from epidemiological surveillance suggest that so far, six months after its introduction to the Caribbean, CHIKV has been responsible for over 350,000 suspected cases of chikungunya fever that have occurred throughout the region.
Forecasting Chikungunya spread in the Americas via data-driven empirical approaches
A simple model incorporating cases generated locally and cases imported from other countries, and forecasted transmission hotspots at the level of countries and at finer scales, in terms of ecological features generated descriptive and predictive information on spread of emerging diseases in the short-term under simple models based on open-access tools and data.
Defining the Risk of Zika and Chikungunya Virus Transmission in Human Population Centers of the Eastern United States
This work demonstrates how a conditional series of non-average events can result in local arbovirus transmission and outbreaks of disease in humans, even in temperate cities.
Chikungunya virus infection: first detection of imported and autochthonous cases in Panama.
The phylogenetic analysis of the two imported isolates and one autochthonous CHIKV isolate indicated that the viruses belong to the Asian lineage in the Caribbean clade and are related to viruses recently identified in Saint Martin island, British Virgin Islands, China, and the Philippines.

Evaluating the effectiveness of localized control strategies to curtail chikungunya
This work developed a model of chikungunya transmission dynamics within a large residential neighborhood, explicitly accounting for human and mosquito movement, and indicates that prompt targeted vector control efforts combined with measures to reduce transmission from symptomatic cases to mosquitoes may be highly effective approaches for controlling outbreaks of the disease.

Chikungunya Epidemic in the Caribbean: An Opportunity to Engage with Communities on Watershed Management
This work provides a methodology to assess the individual out-of-pocket health expenditure and business costs incurred by small island populations from the chikungunya epidemic of 2014, and discusses the opportunity for water resource education as a sustainable management strategy of the disease.

CHIKV initially spread quickly in rural areas mainly via roads, with lesser involvement of urban areas, but delayed spread occurred via river networks to more isolated areas in the rural interior.


A Mathematical Model of Chikungunya Dynamics and Control: The Major Epidemic on Réunion Island
A simple, deterministic mathematical model of the transmission of the virus between humans and mosquitoes was constructed and parameterised with the up-to-date literature on infection biology, and provided a close approximation of both the peak incidence of the outbreak and the final epidemic size.
Chikungunya in the Americas
A review of the invasive mosquitoes in Europe: ecology, public health risks, and control options.
Current understanding of all exotic aedine species in Europe is reviewed, highlighting the known import pathways, biotic and abiotic constraints for establishment, control strategies, and public health significance, and encourages Europe-wide surveillance for invasive mosquitoes.
Estimating Chikungunya prevalence in La Réunion Island outbreak by serosurveys: Two methods for two critical times of the epidemic
A rapid serosurvey in pregnant women can be helpful to assess the attack rate when large seroprevalence studies cannot be done and a population-basedserological assessment is useful to refine the estimate when clinical diagnosis underestimates it.

This work suggests that the reproduction ratio was less than 2.2 - 3.1 in Mexico, depending on the generation interval, which remains to be estimated for the current epidemic.
Spatial dynamics of the 1918 influenza pandemic in England, Wales and the United States
To better characterize the spread of the 1918 major wave, a range of city-to-city transmission models are fitted to mortality data collected for 246 population centres in England and Wales and 47 cities in the US and it is found that parameters estimated from theEngland and Wales dataset can be applied to the US data with no likelihood penalty.
Refining the Global Spatial Limits of Dengue Virus Transmission by Evidence-Based Consensus
A contemporary global map of national-level dengue status is generated that assigns a relative measure of certainty and identifies gaps in the available evidence and provides a preliminary estimate of population at risk with an upper bound of 3.97 billion people.
The Chikungunya Epidemic on La Réunion Island in 2005–2006: A Cost-of-Illness Study
The medical management of chikungunya during the epidemic on La Réunion Island was associated with an important economic burden and the estimated cost of the reported disease can be used to evaluate the cost/efficacy and cost/benefit ratios for prevention and control programmes of emerging arboviruses.
Oviposition, dispersal, and survival in Aedes aegypti: implications for the efficacy of control strategies.

There is compelling evidence that Aedes aegypti distributes small numbers of eggs among many sites, and that this "skip oviposition" is a driver for dispersal, which limits the efficacy of attempts to suppress dengue transmission by source reduction and "focal" treatments with aerosols.
Multiscale mobility networks and the spatial spreading of infectious diseases
The present approach outlines the possibility for the definition of layered computational approaches where different modeling assumptions and granularities can be used consistently in a unifying multiscale framework.
