INTRODUCTION: A considerable increase of imported Zika virus (ZIKV) infection has been reported in Europe in the last year. This is the result of the large outbreak of the disease in the Americas, along with the increase in the numbers of travellers and immigrants arriving from ZIKV endemic areas. METHODS: A descriptive study was conducted in the Tropical Medicine Unit of Hospital La Paz-Carlos III in Madrid on travellers returning from an endemic area for ZIKV from January to April 2016...

OBJECTIVE: Geographical information systems (GIS) use for development of epidemiological maps in tropical diseases is increasingly frequently utilized. Here, we apply this technique to map the current Zika virus (ZIKV) outbreak in Colombia. METHODS: Surveillance cases data of the ongoing epidemic of ZIKV in Valle del Cauca department and its capital, Cali (2015-2016), were used to estimate cumulated incidence rates (cases/100,000 population) to develop the first maps in the department and it municipalities...

Background Zika virus (ZIKV) infection has been linked to the Guillain-Barré syndrome. From November 2015 through March 2016, clusters of cases of the Guillain-Barré syndrome were observed during the outbreak of ZIKV infection in Colombia. We characterized the clinical features of cases of Guillain-Barré syndrome in the context of this ZIKV infection outbreak and investigated their relationship with ZIKV infection. Methods A total of 68 patients with the Guillain-Barré syndrome at six Colombian hospitals were evaluated clinically, and virologic studies were completed for 42 of the patients...

INTRODUCTION: Aedes aegypti is the main vector of urban yellow fever, dengue, chikungunya and Zika viruses. The biogeographical distribution of this species has expanded due to global warming, and socioeconomic and cultural factors. The changes in the altitudinal distribution patterns of this vector and its natural infection are priority fields of research to develop entomological, virological and public health surveillance strategies.  OBJECTIVE: To evaluate the presence of A...

Zika virus is a flavivirus isolated in non human primates in 1647, then in humans 1954 (Uganda). It emerged on Micronesia (island af Yap) in 2007, then in French Polynesia in 2013-2014, in South America (mostly in Brazil and Colombia) in 2015 and in French West Indies in 2016. It is transmitted by the bite of Aedes mosquitoes. Zika virus infection is symptomatic in only 20% of cases and clinical presentation is associated with mild illness. But several neurological complications are reported (as Guillain-Barré syndrome: 48 cases in French Polynesia) and congenital malformations (microcephaly)...

Infection with Zika virus (ZV) has become a new epidemic, with great impact on the media, and is having a strong effect in Latin American countries. Its possible association with microcephaly and Guillain-Barré syndrome prompted the World Health Organization (WHO) to declare on 1 February 2016 that this epidemic is a public health emergency of international concern. Epidemiological data show an increasing incidence in countries like Brazil and Colombia, and that the epidemic is still expanding in many other countries...

Zika virus (ZIKV) is a single-stranded RNA virus in the Flaviviridae family and transmitted to human through infected mosquitos (Aedes aegypti and Aedes albopictus). Virus is closely related with other flaviviruses; dengue virus, yellow fever virus, West Nile virus, and Japanese encephalitis virus phylogenetically. Due to the possible relationship between virus and clinical features including microcephaly, ventricule, and eye deformities, Guillain-Barre syndrome increases the interest on this virus gradually...

Background: Because of the risk for Zika virus infection in the Americas and the links between infection and microcephaly, other serious neurologic conditions, and fetal death, health ministries across the region have advised women to delay pregnancy. However, the effectiveness of this policy in reducing prenatal Zika virus infection has yet to be quantified. Objective: To evaluate the effectiveness of pregnancy-delay policies on the incidence and prevalence of prenatal Zika virus infection...

Transmission of Zika virus (ZIKV) was first detected in Colombia in September 2015. As of April 2016, Colombia had reported over 65,000 cases of Zika virus disease (ZVD). We analysed daily surveillance data of ZVD cases reported to the health authorities of San Andres and Girardot, Colombia, between September 2015 and January 2016. ZVD was laboratory-confirmed by reverse transcription-polymerase chain reaction (RT-PCR) in the serum of acute cases within five days of symptom onset. We use daily incidence data to estimate the basic reproductive number (R0) in each population...

Guillain-Barré syndrome (GBS) is a rapid-onset muscle weakness disease caused by the immune-mediated damage of the peripheral nervous system. Since there is an increase incidence of GBS cases in Latin America, particularly in Colombia, and most of them are currently preceded by Zika virus (ZIKV) infection, we aimed to assess the available evidence of the disease in Colombia through a systematic literature review. Out of 51 screened abstracts, only 16 corresponded to articles that met inclusion criteria, of which 15 were case reports or case series...

Since the first cases of Zika were identified and reported in Brazil, the magnitude and consequences of the outbreak in the Americas have increased tremendously, leading the World Health Organization to consider Zika and its link with clusters of microcephaly a Public Health Emergency of International Concern. Only a previous large outbreak in French Polynesia was known and no neurological anomalies have been reported. Differences in African and Asian lineage and differences in genetic evolution of the Zika virus may possibly provide an explanation for the development of the recent outbreaks and their variable presentation...

Zika virus (ZIKV) is causing an explosive outbreak of febrile disease in the Americas. There are no effective antiviral therapies or licensed vaccines for this virus, and mosquito control strategies have not been adequate to contain the virus. A promising candidate for arbovirus control and prevention relies on the introduction of the intracellular bacterium Wolbachia into Aedes aegypti mosquitoes. This primarily has been proposed as a tool to control dengue virus (DENV) transmission; however, evidence suggests Wolbachia infections confer protection for Ae...

ZIKV infection has become a global threat spreading across 31 countries in Central America, South America, and the Caribbean. However, little information is available about the molecular epidemiology of ZIKV. Shared mutation of a threonine residue to alanine at the same position in the C terminal of NS5 sequences was observed in sequences from Colombia, Mexico, Panama, and Martinique. The sequences in the phylogenetic tree fell within the same cluster. Based on shared mutation the presence of a Latin American genotype was proposed...

The ongoing Zika virus (ZIKV) epidemic in the Americas poses a major global public health emergency. While ZIKV is transmitted from human to human by bites of Aedes mosquitoes, recent evidence indicates that ZIKV can also be transmitted via sexual contact with cases of sexually transmitted ZIKV reported in Argentina, Canada, Chile, France, Italy, New Zealand, Peru, Portugal, and the USA. Yet, the role of sexual transmission on the spread and control of ZIKV infection is not well-understood. We introduce a mathematical model to investigate the impact of mosquito-borne and sexual transmission on the spread and control of ZIKV and calibrate the model to ZIKV epidemic data from Brazil, Colombia, and El Salvador...

Background Colombia began official surveillance for Zika virus disease (ZVD) in August 2015. In October 2015, an outbreak of ZVD was declared after laboratory-confirmed disease was identified in nine patients. Methods Using the national population-based surveillance system, we assessed patients with clinical symptoms of ZVD from August 9, 2015, to April 2, 2016. Laboratory test results and pregnancy outcomes were evaluated for a subgroup of pregnant women. Concurrently, we investigated reports of microcephaly for evidence of congenital ZVD...

BACKGROUND: Approximately 40 countries in Central and South America have experienced local vector-born transmission of Zika virus, resulting in nearly 300,000 total reported cases of Zika virus disease to date. Of the cases that have sought care thus far in the region, more than 70,000 have been reported out of Colombia. OBJECTIVE: In this paper, we use nontraditional digital disease surveillance data via HealthMap and Google Trends to develop near real-time estimates for the basic (R) and observed (Robs) reproductive numbers associated with Zika virus disease in Colombia...

BACKGROUND: As Zika virus continues to spread, decisions regarding resource allocations to control the outbreak underscore the need for a tool to weigh policies according to their cost and the health burden they could avert. For example, to combat the current Zika outbreak the US President requested the allocation of $1.8 billion from Congress in February 2016. METHODOLOGY/PRINCIPAL FINDINGS: Illustrated through an interactive tool, we evaluated how the number of Zika cases averted, the period during pregnancy in which Zika infection poses a risk of microcephaly, and probabilities of microcephaly and Guillain-Barré Syndrome (GBS) impact the cost at which an intervention is cost-effective...
