Study of Brazil favela stricken by Zika shows dengue may protect against virus

Analysis of community where 73% of residents contracted Zika in 2015 offers new clues about epidemicScientists studying the 2015 Zika outbreak in Brazil have discovered that people previously exposed to dengue may have been protected from the virus.Three-quarters of the inhabitants of a favela in the country’s north-east caught the mosquito-borne Zika virus during the epidemic. The outbreak left more than 3,000 babies across Brazil with microcephaly, a birth defect caused by mothers catching the...

Prior dengue virus infection increases Zika virus-induced damage during pregnancy

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.

Immunity to dengue can protect against Zika infection, study shows

In the epicenter of the Zika epidemic in northeast Brazil, 73 percent of people living in an urban slum in Salvador were infected in 2015. However, in this highly affected population, those with immunity to dengue, a genetically similar virus, had a reduced risk of infection with Zika.

Scientists wean mosquitoes off blood with dieting drugs

Researchers have found a way to reduce the blood thirst of mosquitoes and prevent mosquito bites and spread of mosquito borne illnesses such as Zika, dengue fever, malaria and chikungunya.

Prior dengue infection may protect against Zika: study

The finding, published in the journal Science, could have implications for approved and experimental dengue vaccines by Sanofi, Takeda Pharmaceutical, Merck & Co and Brazil's Butantan Institute, they said. It was based on tests of blood samples from a long-running study of nearly 1,500 women in Salvador, a city in northeast Brazil that was hard hit by the Zika epidemic that began in 2015. Dengue and Zika are closely related diseases.

Diet Drugs Might Make Mosquitoes Stop Thirsting for Our Blood

Losing weight is definitely tough. So tough, in fact, that scientists have tried to whip up drugs that trick us into feeling full and suppress our appetite. But these concoctions might not just work in people, suggest the authors of a new study out Thursday in Cell. They found that some of these same drugs could also…Read more...

Solo Female Travel in Mexico — Is it Safe?

Is it safe for a woman to travel alone in Mexico? ABSOLUTELY. Mexico gets a undeserved bad reputation for travel, particularly in the United States. Much of this is due to the cable news environment with its exaggerated narratives that Mexico is full of drug cartels and murderous immigrants. This is not what Mexico is actually like. In fact, the real Mexico is so different that you’ll be stunned. My name is Kate and I write about solo female travel for a living. And I’ve spent a lot of time tra...

Impact of preexisting dengue immunity on Zika virus emergence in a dengue endemic region

The clinical outcomes associated with Zika virus (ZIKV) in the Americas have been well documented, but other aspects of the pandemic, such as attack rates and risk factors, are poorly understood. We prospectively followed a cohort of 1453 urban residents in Salvador, Brazil, and, using an assay that measured immunoglobulin G3 (IgG3) responses against ZIKV NS1 antigen, we estimated that 73% of individuals were infected during the 2015 outbreak. Attack rates were spatially heterogeneous, varying b...

The protective role of dengue immunity on Zika infection in a Brazilian favela

By monitoring the spread of Zika virus through a densely populated Brazilian favela during a 2015 outbreak, researchers have gained new perspectives into the outbreaks of this virus in the Americas in recent years.

New findings could make mosquitos more satisfied -- and safer to be around

Scientists have learned new tricks that could be useful in preventing mosquito-borne illnesses such as Zika and yellow fever. A new study shows that some appetite-reducing drugs can curtail the insects' impulse to feed on warm-blooded hosts.

Study: CD4+ T cells could be important mediators of protection against Zika virus

Immune cells called CD4+ T cells could be important mediators of protection against the Zika virus, according to a study published January 24 in the open-access journal PLOS Pathogens by Sujan Shresta of the La Jolla Institute for Allergy and Immunology, and colleagues.

Zika vaccines should induce responses by CD4+ T cells

Immune cells called CD4+ T cells could be important mediators of protection against the Zika virus, according to a new study. The findings support vaccine strategies that induce a protective CD4+ T cell response to the Zika virus.

Study: Prior dengue immunity in children may be protective against symptomatic Zika

Children with a history of prior dengue virus infection had a significantly lower risk of being symptomatic when infected by Zika virus, according to a study in Nicaragua of more than 3,000 children aged 2 to 14 years.

Dengue immunity may be protective against symptomatic Zika, study finds

Children with a history of prior dengue virus infection had a significantly lower risk of being symptomatic when infected by Zika virus, according to a study in Nicaragua of more than 3,000 children aged 2 to 14 years. Experts have worried that prior dengue virus infection could exacerbate severe Zika disease. However, the new findings, published in PLOS Medicine, indicate that prior dengue immunity in children may in fact be protective against symptomatic Zika disease.

Screening donated blood for Zika not cost-effective

Universal screening of individual blood donations for Zika virus, which began in 2016, was not cost-effective in the 50 states during the first year. Widespread screening would only be cost-effective in the high mosquito season in Puerto Rico and never in the 50 states. Findings from a microsimulation study are published in Annals of Internal Medicine.
