Other Viruses Cause Zika-Like Damage to Fetuses, Study Finds

In 2016, the US Centers for Disease Control and Prevention confirmed that the Zika virus caused birth defects in babies born to women who had been infected while pregnant. This was the first mosquito-borne disease known to cause birth defects . . . 

 . . . Now, a study suggests that two viruses that are related to Zika can cause similar birth defects.

West Nile and Powassan viruses caused fetal death in infected pregnant mice, the researchers say.

Zika Linked to a Spike in Birth Defects in the U.S.

time.com - by Alexandra Sifferlin - January 25, 2018

Areas in the United States where Zika spread locally, like Florida and Texas, experienced a spike in birth defects.

According to a new report from the U.S. Centers for Disease Control and Prevention (CDC), areas in South Florida, parts of Texas and Puerto Rico saw a 21% increase in birth defects strongly linked with Zika in the last half of 2016, compared to the first part of the year.

Researchers Identify Three New Mosquito Vectors of Zika in Mexico

CLICK HERE - RESEARCH - Zika Virus in Salivary Glands of Five Different Species of Wild-Caught Mosquitoes from Mexico

mvcac.org - January 25, 2018

Researchers identified three new mosquito carriers of Zika virus in Mexico and say all three are potential vectors of the disease.

Writing in Scientific Reports, the researchers reported isolating Zika virus from the salivary glands of wild-caught female Culex coronator, C.tarsalis and Aedes vexans mosquitoes, as well as other previously reported vectors, including A. aegypti, the primary driver of the recent Zika virus epidemic in the Americas. They also isolated Zika from different body parts of wild-caught female C. quinquefasciatus mosquitoes and whole males from the A.aegypti and C. quinquefasciatus species.

“Our findings strongly suggest that all the species reported herein are potential vectors for [Zika virus],” they wrote.

reuters.com - by Julie Steenhuysen - December 13, 2017

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

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.
