Yellow fever was the first human disease to have a licensed vaccine and has long been considered important to understanding how epidemics break out and should be combated. It was introduced to the Americas in the 17th century, and high death rates have resulted from successive outbreaks since then. Epidemics of yellow fever were associated
Zika virus infection can stunt neonatal brain development, a condition known as microcephaly, in which babies are born with abnormally small heads. To determine how best to prevent and treat the viral infection, scientists first need to understand how the pathogen gets inside brain cells. Employing different approaches to answer different questions, two research teams
Many viruses have been recognized to be a fatal triumph to the world. Tropical pathogens, such as the Zika Virus appears, increasingly, to Europe, among other things, because the transmitting mosquitoes spread increased. Germany, too, new disease waves threaten to completely. Exotic pathogens spread increasingly also in Europe. Currently, French authorities have reported two first,
Researchers from the University of Oxford teamed up with the Angolan Ministry of Health to study the introduction and circulation of the Asian genotype of Zika virus in Angola, southwestern Africa. The Asian genotype caused the 2015-16 epidemic of microcephaly and other birth defects in the Americas. Their findings are published today in The Lancet
New research led by scientists at The Rockefeller University in New York may help explain why Zika virus infection causes birth defects in some children but not others. The study, which will be published August 14 in the Journal of Experimental Medicine, suggests that the risk of developing an abnormally small head (microcephaly) depends on
In experiments with pregnant mice infected with the Zika virus, Johns Hopkins Medicine researchers report they have successfully used a long-standing immunosuppressive drug to diminish the rate of fetal deaths and birth defects in the mice’s offspring. The U.S. Food and Drug Administration-approved medicine, anakinra, once commonly used to treat rheumatoid arthritis and other autoimmune
Women who have previously been infected with dengue virus may be at risk for increased damage to their fetuses and placentas if they should later become infected with the Zika virus, researchers from the Department of Microbiology at the Icahn School of Medicine at Mount Sinai report. This study is the first to report a
Previous infection with dengue virus may protect children from symptomatic Zika, according to a study published January 22 in the open-access journal PLOS Medicine by Eva Harris of the University of California, Berkeley, and colleagues. Zika virus emerged in northeast Brazil in 2015 and spread rapidly across the Americas, affecting populations that have been largely
Vaccinations have begun in a first-in-human trial of an experimental live, attenuated Zika virus vaccine developed by scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. The trial will enroll a total of 28 healthy, non-pregnant adults ages 18 to 50 at the Johns Hopkins Bloomberg
Dengue and Zika viruses are closely related and carried by mosquitos. In infested subtropical and tropical areas, dengue transmission often precedes Zika virus (ZIKV) infection, suggesting that women who previously acquired dengue immunity may be bitten by ZIKV-carrying mosquitoes during pregnancy. Whether that mother’s prior dengue immunity would protect her unborn baby from devastating brain
In a summer outbreak that posed significant risks to pregnant women and their fetuses, 29 people in Miami-Dade County were infected with the Zika virus between late June and early August of 2016, according to the Centers for Disease Control and Prevention. To understand people’s perceptions, behaviors, and knowledge about the outbreak, and whether county
Over the last five years, Zika virus has emerged as a significant global human health threat following outbreaks in South and Central America. Now, researchers reporting in PLOS Neglected Tropical Diseases have shown that invasive mosquitoes in California — where cases of Zika in travelers have been a regular occurrence in recent years — are
Threatened by the mosquito-borne Zika virus in 2016, Florida residents felt more susceptible than others in the United States to getting the virus, were more knowledgeable about it, and were more likely to support taking community action against it. Floridians were nearly twice as likely as non-Floridians to say they took steps to protect themselves
Bioengineers have compiled a set of recommendations that could significantly reduce concussions and other head injuries in rugby union, having assessed how head impacts and movement vary based on the position on the body where tackles are made. The bioengineers discovered that the risks are not precisely the same for the two groups, as tacklers
