Zika virus can be present in the bloodstream for around four weeks after the onset of symptoms. Recent evidence suggests a possible association between maternal Zika virus infection and adverse fetal outcomes, such as congenital microcephaly (4,5), as well as a possible association with Guillain-Barre syndrome. It was performed an electronic search in online databases, with articles published between the years of 2004-2018. Zika Virus 2 Zika Virus The Zika Virus affects many different places around the world. Since the competent mosquito vectors are highly prevalent in most tropical and subtropical countries, introduction of the virus to these areas could readily result in endemic transmission of the disease.

Researchers are learning more about any long-term effects that Zika. The study purposes making a comparative survey between the involvement of dengue, Zika and chikungunya infections in the development of the GBS in Brazil, as well as. In most infected patients the disease is relatively benign. The globalization of the Zika virus was made possible by the widespread presence in various parts of the world of Aedes vectors and increased human travel that facilitated geographic spread. fter the first isolation of Zika virus (ZIKV) in 1947 from a rhesus monkey (1), ZIKV infection in humans was first de-scribed in Nigeria (Africa) in 1954 (2).

In addition to bite avoidance, At present, the only flaviviral vaccines available, mosquito nets during the day. • Through blood transfusion (likely but not confirmed). The majority of people infected with Zika virus do not develop symptoms. A total of 729 articles about the proposed search were found, and 10 were selected according to inclusion and exclusion criteria. The wide distribution of Aedes aegypti, a principal vector of the virus, and other Aedes species has greatly facilitated the spread of the disease. Micrencephaly (an abnormally small brain) was observed, with almost complete agyria, hydrocephalus, and multifocal dystrophic calcifications in the cortex and subcortical white matter, with associated cortical displacement and mild focal inflammation.

Zika virus infection—the next wave after dengue? Many questions about the Zika. Although most infections are asymptomatic or present with benign, self-limited symptoms, a small percentage of patients have complications, such as congenital anomalies in the developing fetus of pregnant women infected with the virus and neurological complications (eg, Guillain-Barré syndrome).

Zika virus (ZIKV) is a flavivirus related to yellow fever virus that until recently has been considered endemic to Africa and Southeast Asia, but human cases are rare. And current technological devices and services can assist them in this process. to 30% is generally recommended for adult use. For half a century, fewer than 20 human infections were documented (3) and most of the data came from yellow fever virus (YFV) serosurveys. << /Length 5 0 R /Filter /FlateDecode >> 2014). Existing vector disease surveillance systems will be adapted and enhanced to track, detect and monitor the Zika virus. Zika virus test kits have been made available by the local authorities at the Central Public Health Laboratory in Rio de Janeiro in Brazil and symptomatic athletes, volunteers, visitors and residents are encouraged to get tested. This finding adds a potentially noxious virus to a list of several other viruses that are widely transmitted by Aedes (Stegomyia) aegypti and Aedes (Stegomyia) albopictus in Brazil. In 1952, the first human cases of Zika were detected and since then, outbreaks of Zika have been reported in tropical Africa, Southeast Asia, and the Pacific Islands.

History of Zika. The number of reported infections through blood donation is very low, even in countries with a Zika epidemic. The virus first came into the limelight in 2007 when it caused an outbreak in Micronesia. It is currently not known if cases of microcephaly have resulted from infection of pregnant women or from infection plus some other co-factor. While periodic Zika outbreaks have been reported since its discovery, Zika was not identified as a global Zika virus was discovered in a sentinel monkey in Uganda in 1947. Zika virus is not proven to be a cause of the increased incidence of microcephaly in Brazil. The virus has since caused sporadic disease in Africa and Asia. pregnant when they contracted the virus [18]. Aedes aegypti is an invasive species of mosquito in the Western Hemisphere that has adapted well to densely-populated urban environments. Cuevas EL, Tong VT, Rozo N, et al. Download Full PDF Package. During that year and afterwards, microcephaly and other congenital abnormalities were observed in the infants of women who were pregnant when they contracted the virus. albopictus means engagement of the community and citizens is of utmost importance to the success of vector control.

CDC recommends Zika virus testing for symptomatic people living in an active Zika transmission area, or who have recently traveled to an area with Zika, or who have had unprotected sex with a man confirmed to have Zika virus infection. The pathology and epidemiology, including the distribution and vectors associated with Zika virus, are reviewed. The mosquito gets infected by biting a person who has the Zika virus in his or her blood.

ResearchGate has not been able to resolve any citations for this publication. There are many studies that implicated the association of GBS and arboviruses and point it to one of the main neurological manifestation of these infections. a twenty-fold increase in a single year [22, 23]. Facial palsy, paresthesia and member weakness were the main symptoms related. It is most renown to be caused by mosquitoes, and it is considered most consequential in women whom reproduce while having this virus, or if they are exposed to it at some critical point in the fetal or embryonic development. Our results confirmed that Ae. The time lapse for the neurological symptoms manifest was 6,5-11 days.
