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.

thehill.com - by Peter Sullivan - January 19, 2018

The Centers for Disease Control and Prevention is planning to significantly reduce its overseas work to fight disease due to coming funding cutbacks, according to an internal email reported by The Wall Street Journal.

Unless it gets new funding, the CDC will be cutting down its work against diseases from 49 countries to 10 countries starting in October 2019, the Journal reported . . . 

 . . . The 10 countries where the CDC will continue its work are India, Thailand, Vietnam, Kenya, Uganda, Liberia, Nigeria, Senegal, Jordan and Guatemala, the Journal reported.

The CDC said it is starting to plan now to make transitions in the countries it cannot continue the work in.

The 1918 flu did not come from Spain

scientificamerican.com - by Richard Gunderman - January 11, 2018

 . . . The 1918 flu pandemic has been a regular subject of speculation over the last century. Historians and scientists have advanced numerous hypotheses regarding its origin, spread and consequences. As a result, many of us harbor misconceptions about it.

By correcting these 10 myths, we can better understand what actually happened and learn how to prevent and mitigate such disasters in the future.

sciencemag.org - by Jon Cohen - December 14, 2017

Forty years after the first documented Ebola outbreak, some of the survivors still have antibodies against the virus, a new study reveals. The find bolsters the widely held assumption that Ebola survivors remain immune to the virus for life. The work may also help guide development of new medicines and clarify the long-term health consequences of an Ebola infection.

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.

Chinese scientists find all the genetic building blocks of SARS in a single population of horseshoe bats.

After a detective hunt across China, researchers chasing the origin of the deadly SARS virus have finally found their smoking gun. In a remote cave in Yunnan province, virologists have identified a single population of horseshoe bats that harbours virus strains with all the genetic building blocks of the one that jumped to humans in 2002, killing almost 800 people around the world.

Where Does the Ebola Virus Hide Between Outbreaks?

Joe DeRisi, PhD, is a master detective of infectious diseases. No matter how obscure or complex, he says he’ll take on the challenge because “it could lead to new biology that we wouldn’t have discovered otherwise.”

That's precisely what happened when he stumbled on a clue to cracking the decades-long search for the place – or creature – where the Ebola virus hides between deadly outbreaks. . . .

 . . . In 2009, DeRisi began studying an incurable disease that was killing reptiles raised in captivity, a disease that caused strange neurological symptoms ranging from vomiting to uncontrollable contortions. They found the culprit – a previously undescribed arenavirus – and uncovered something surprising: the Arenavirus’s glycoprotein, a viral “access badge” to the secure insides of a cell, actually belonged to the Ebola virus.
