A new study sheds light on how the mosquito-borne Zika virus causes a rare neurological condition, and the findings could have implications for companies working on Zika vaccines, U.S. researchers said on Wednesday . . .

 . . . To study the nerve disorder, Dr. Tyler Sharp of the U.S. Centers for Disease Control and Prevention’s Dengue Branch in San Juan and colleagues in Puerto Rico examined the rare case of a 78-year-old man from San Juan who had been infected with Zika in 2016, developed Guillain-Barre and subsequently died.

An autopsy showed inflammation and erosion of the protective sheath known as myelin in two nerves, but no evidence of the Zika virus in nerve cells.

Zika Linked to Rising Tide of Serious Neurologic Complications in Adults

CLICK HERE - JAMA Neurology - Neurologic Complications Associated With the Zika Virus in Brazilian Adults

medscape.com - by Nancy A. Melville - August 15, 2017

A rising tide of serious neurologic complications among adults in Brazil has been linked to the spread of the Zika virus, new research shows.

"Our study is the first prospective study assessing the occurrence of neurological complications in adults secondary to Zika virus infection, with all previous data based solely on case series and case reports," senior author, Osvaldo Jose Moreira do Nascimento, MD, PhD, from the Neurology Department at Universidade Federal Fluminense, Copacabana, Rio de Janeiro, Brazil, told Medscape Medical News.

"We observed an increase in the admissions of patients with inflammatory complications, such as Guillain-Barré syndrome (GBS), myelitis and encephalitis."

The study was published online August 14 in JAMA Neurology.

Climate Change Pushing Tropical Diseases Toward Arctic

Temperature changes around the globe are pushing human pathogens of all kinds into unexpected new areas, raising many new risks for people.

 . . . It's no secret that climate change can spread illnesses such as West Nile virus, Zika, and malaria, as rising temperatures push disease-carrying mosquitoes into new places, from the highlands of Ethiopia to the United States. But warm temperatures and shifting weather patterns work in subtle ways, too. Changes in precipitation, wind, or heat are shifting the threat posed by other human illnesses, from cholera to a rare freshwater brain-eating amoeba to rodent-driven infections like hantavirus. And the importance of all these changes are only growing more significant.

Miami's Zika Outbreak Began Months Before It Was First Detected

npr.org - by Greg Allen - May 24, 2017

Last year's Zika outbreak in Miami likely started in the spring of 2016, with the virus introduced multiple times before it was detected, researchers say. And most of those cases originated in the Caribbean.

The study, published Wednesday in Nature, examined more than 250 cases of local Zika transmission in three Miami neighborhoods. Researchers analyzed 39 Zika virus genomes isolated from 32 people who had been infected and seven Aedes aegypti mosquitoes, the species that carries Zika.

Comparison of differences in those genomes finds the virus was introduced by travelers at least four and perhaps as many as 40 different times as early as March 2016. Local transmission of Zika wasn't confirmed in Miami until late July.

New Zika Virus Inhibitor Identified

CLICK HERE - RESEARCH - Characterization of the Zika virus two-component NS2B-NS3 protease and structure-assisted identification of allosteric small-molecule antagonists

business-standard.com - ANI - May 17, 2017

A new research has brought a drug to treat Zika infections closer to reality.

The team led by Alexey Terskikh and Alex Strongin from Sanford Burnham Prebys Medical Discovery Institute (SBP) discovered a compound that prevents the virus from spreading.

"We identified a small molecule that inhibits the Zika virus protease, and show that it blocks viral propagation in human cells and in mice," Terskikh said. "Anti-Zika drugs are desperately needed. The fact that the compound seems to work in vivo is really promising, so we plan to use it as a starting point to make an even more potent and effective drug."

The Zika virus stands to cost the United States billions of dollars, even if few people are infected.

Researchers from several American institutions have calculated that the "virus from Hell" could result in total costs ranging from $183 million to over $1.2 billion, depending on infection rates in several at-risk states in the South.

The researchers warn that infection rates could engender costs that exceed the amounts of money the U.S. government may give for prevention and treatment, if the recent debates over funding are any indication.

statnews.com - by Helen Branswell - May 5, 2017

 . . . Testing for Zika infection is becoming more difficult, making it harder for doctors to advise pregnant women about the chances their child might have a Zika-related birth defect, the Centers for Disease Control and Prevention revealed in a health advisory issued Friday.

The CDC is now suggesting that women thinking of getting pregnant, and who may be exposed to the Zika virus through travel or because of where they live, should consider having their blood tested for Zika antibodies before they get pregnant. Having a baseline reading would help to interpret Zika tests done during a later pregnancy.
