In early 2015, a widespread epidemic of Zika fever, caused by the Zika virus in Brazil, spread to other parts of South and North America.It also affected several islands in the Pacific, and Southeast Asia. In January 2016, the World Health Organization (WHO) said the virus was likely to spread throughout most of the Americas by the end of the year. In November 2016, WHO announced the end of.
In 1947, the Zika virus was first isolated from monkeys in the Zika Forest of Uganda but was not considered an important human pathogen until the first large-scale outbreaks in the South Pacific islands in 2007. In May 2015, local transmission was first reported in South America, then in Central America and in the Caribbean, reaching Mexico by late November 2015.
Before 2007, the areas with reported Zika virus circulation included tropical Africa and south-east Asia. Very few outbreaks were documented prior to a 2007 upsurge on Yap Island, Federated States of Micronesia (8), which was the first outbreak of Zika virus identified outside of Africa and Asia. Between 2013 and 2015, several significant outbreaks were notified on islands and archipelagos in.
Background Zika is of great medical relevance due to its rapid geographical spread in 2015 and 2016 in South America and its serious implications, for example, certain birth defects. Recent epidemics urgently require a better understanding of geographic patterns of the Zika virus transmission risk. This study aims to map the Zika virus transmission risk in South and Central America.
Do African countries have to worry about a zika resurgence? The zika virus is sweeping across South America, but it is an Asian mutation, different from the strains endemic in African countries.
Zika outbreaks have been reported in the Pacific region, South and Central America, the Caribbean, Africa, and parts of south and southeast Asia. If you plan to travel to an affected area, seek travel health advice before your trip.
Zika virus infection (ZIKV), transmitted primarily by the Aedes aegypti and Ae. albopictus mosquitoes, is a serious threat to pregnant women because of the risk of microcephaly and other birth defects in infants (1,2).In late 2015, an unprecedented ZIKV outbreak emerged in South America and spread rapidly into other parts of the Americas.
Both babies with and without microcephaly can have eye problems. If your baby was born with congenital Zika infection, he or she should receive the recommended screenings and tests to check for eye and other health problems, even if your baby appears healthy. A recent study in Brazil found that at 19-24 months, babies with congenital Zika virus infection exhibited challenges with sitting.
Frequently the infection goes without or with mild symptoms. So far there are just occasional deaths documented among people whose immune system already has been weakened by other illness. The most affected countries by the Zika virus are located in Central and South America, especially Bolivia, Brazil, Colombia, Ecuador, Guatemala, Mexico, Panama and Paraguay.
In 2015, a mutant virus reached South America, where its spread became epidemic. Cases of Zika fever were recorded in Russia, the USA, Spain, and a number of African and Asian countries. But by the end of 2016, the epidemic in South America had waned. However, even later, residents of Asian and African countries suffered from Zika fever, and, as genetic analysis showed in some cases, the virus.
Zika virus outbreak in South America Updated 28thApril 2016. Dr Anna Checkley, on behalf of the Hospital for Tropical Diseases, London What is Zika virus? Zika virus occurs in a wide range of tropical countries, and there is currently a large outbreak in the Americas. It is transmitted by the same mosquito that transmits dengue.
Author summary In February 2016 the World Health Organisation (WHO) declared Zika virus infection in the Americas as a Public Health Emergency of International Concern (PHEIC). By November 2016, Zika was declared a long-term public health challenge. This change of status implies that Zika is likely to become an endemic problem in the region. Due to the PHEIC status of Zika, most current.
Zika, one of the world's oddest viruses, is causing a commotion in the Western Hemisphere and sapping productivity in Brazil, one of the most dynamic economic powerhouses in South America and the.
Preventing the Zika Virus: Understanding and Controlling the Aedes Mosquito Preventing the Zika Virus: Understanding and Controlling the Aedes Mosquito Look at the science behind the Zika outbreak in order to try and understand where the virus has come from, its symptoms, their effect on infected individuals, and how it can be controlled.
Objective To describe the prevalence and clinical spectrum of microcephaly in South America for the period 2005-14, before the start of the Zika epidemic in 2015, as a baseline for future surveillance as the Zika epidemic spreads and as other infectious causes may emerge in future. Design Prevalence and case-control study.The infection often occurs without symptoms but can also cause an illness similar to dengue. The condition is usually mild and short-lived; severe disease is uncommon. However, a possible link between exposure to Zika virus (ZIKV) in pregnancy and microcephaly and other congenital malformations has been identified and investigations are ongoing. The Zika virus was first identified in Uganda in.The following Zika-free beach destinations are some of our favorite warm-weather escapes.
