Correspondence Guillain-Barr é syndrome and arboviral infection in Brazil

Among the clinical manifestations associated with the recent Zika infection outbreak in South America and elsewhere are rash, conjunctivitis, Guillain-Barr é syndrome (GBS) in exposed adults, and in the newborn so-called congenital Zika syndrome, especially microcephaly.1 After accumulating epidemiological data from the French Polynesia2 outbreak, attention has now focused on Zika infection as a trigger of GBS. The case for a specific, causal associat ion between acute Zika infection and subsequent GBS was strongly made: 42 individuals were diagnosed with GBS, of whom all had Zika neutralising antibodies.

This study accessed the patients information on demographic characteristics, physical signs and symptoms. Study population This is a cross-sectional and observational study carried out in Brazil during DENV and ZIKV epidemic occurred in 2016. Patients were assisted at the Healthy Unit UPA Coronel Antonino in Campo Grande, MS, Brazil from February to March of 2016. During the study 134 suspected arboviral infection cases were included and submitted to investigation. Patients presenting fever, rash during acute phase of infection (up to the 7th day after disease onset) followed by at least two of the following signals a...

AbstractZika virus (ZIKV) is an arbovirus transmitted mainly by mosquitos ofAedes species. The virus has emerged in recent years and spread throughout North and South Americas. The recent outbreak of ZIKV started in Brazil (2015) has resulted in infections surpassing a million mark. Contrary to the previous beliefs that Zika causes mildly symptomatic infections fever, headache, rash, arthralgia, and conjunctivitis, the recent outbreak associated ZIKV to serious neurological complications such as microcephaly, Guillain-Barr é syndrome, and eye infections. The recent outbreak has resulted in an astonishing number of m...

Discussion In areas of the US and Hawaii where there is potential risk of ZIKV transmission, detecting transmission should it occur is a key public health objective17. This poses a challenge for surveillance systems: to balance the probability of detecting ZIKV transmission with the resources needed to carry out surveillance when infections may be rare. An efficient surveillance system should have high sensitivity (a relatively high probability of detecting infections) and high specificity (a low probability of a positive test result in an individual without infection). Comparing three general surveillance systems, we fou...

Abstract Zika Virus (ZIKV), originally identified in 1947, is a re-emerging Flavivirus transmitted mainly through bites by Aedes mosquitos. Until the recent outbreaks in the Pacific islands and Central and South America, it was known to cause benign disease, in most cases asymptomatic or with mild and nonspecific symptoms (fever, rash, conjunctivitis, arthralgia, etc.). The unprecedented current epidemic has highlighted new modes of transmission (through blood, perinatally and sexually) as well as serious neurological complications such as congenital defects in the fetuses of infected mothers and Guillain-Barre sy...

We report the results of a rapid assessment of Zika virus awareness among key clinical specialties in Singapore, with the aim of identifying gaps in knowledge and opportunities for improving communication on Zika virus disease management and control policies. Methods Study Participants and Sites Between June 6 and June 19, 2016 prior to the Zika virus outbreak, we conducted an online survey of doctors working in obstetrics and gynaecology, neonatology and paediatrics in Singapore. A link to the online survey was disseminated by email to the relevant doctors at KK women’s and Children’s Hospital and Singapo...

Abstract The Zika virus is a positive sense, single-stranded RNA arbovirus in the Flaviviridae family, genus Flavivirus. This virus was initially isolated in Africa and is transmitted to nonhuman primates and humans by mosquitoes. Initial reports describe sporadic mild viral infection with fever, arthralgia, myalgia and conjunctivitis in Africa and Asia. However, its geographic distribution has significantly increased, and it has caused large outbreaks in the Yap Islands in 2007, in French Polynesia in 2013 and in Brazil in 2015. Multiple cases of Guillain-Barre´ syndrome occurred in French Polynesia and Col...

Zika virus has been a recent international public health concern with outbreaks occurring in the Americas, Caribbean, and Pacific. The zoonotic infection is primarily spread to humans by the bite of an infected Aedes mosquito. The virus also can be transmitted via bodily fluids, sexual intercourse, and maternal-fetal vertical transmission. Asymptomatic presentation is common. If symptoms do occur, individuals display a low-grade fever, maculopapular rash, arthralgia, or conjunctivitis 2 to 7 d after infection. Infection is concerning due to its associated fetal effects in pregnant women and relationship with Guillain-Barre...

Zika virus is a single-stranded RNA virus (genus Flavivirus) transmitted by the Aedes mosquito and through sexual contact with infected individuals.1,2 Zika virus infection may be asymptomatic or may cause fever, rash, joint pain, conjunctivitis, myalgias, and headache.1 Initially endemic to Africa and Asia, outbreaks in the Pacific Islands occurred in 2007 and 2013, and Central America, South America, and the Caribbean islands are currently in the midst of an epidemic. In both prior and current outbreaks of Zika,1 an increased incidence of Guillain-Barré syndrome (GBS) has been reported.
