Research being presented today at the 2016 American Association of Pharmaceutical Scientist (AAPS) Annual Meeting and Exposition, which is taking place Nov. 13 -17 in Denver, found that under certain conditions, the Zika virus can live for several hours on hard non-porous surfaces and still be highly contagious, but that some commonly used disinfectants are extremely effective in killing the virus. The research may have important infection control implications for both consumers and those who work in healthcare or lab settings.

Antibody Might Protect Fetus From Zika, Study Finds

           

A researcher holds a tray of Zika virus growing in cells at Washington University School of Medicine in St. Louis. No treatments exist to block Zika virus in a pregnant woman from infecting her fetus and potentially causing severe birth defects. But now, researchers report that they have identified a human antibody that prevents -- in pregnant mice -- the fetus from becoming infected and damage to the placenta. The antibody also protects adult mice from Zika disease.  Photo: Huy Mach

Researchers reported two steps toward fighting the Zika virus Monday — one from a team that has found a potential way to protect unborn babies from the virus, and a second from a team that announced the start of human trials of a new vaccine.

Neither offers immediate relief against the epidemic of Zika that has swept across the Americas and the Caribbean and parts of Asia, but they both provide hope of eventually being able to protect pregnant women and their babies from the infection.

New Case Emerging for Culex Mosquito as Unexpected Zika Spreader

Early data from new lab tests reopen question of non-Aedes vectors

           

SPREADING NEWS  The controversial idea that a Culex mosquito (shown) can spread Zika is getting some reconsideration as new data are emerging from separate labs.

sciencenews.org - by Susan Milius - September 28, 2016

ORLANDO, Fla. — New evidence from separate labs supports the controversial idea that an overlooked and unexpected Culex mosquito might spread Zika virus.

The southern house mosquito, Culex quinquefasciatus, is common in the Americas. Constância Ayres, working with Brazil’s Oswaldo Cruz Foundation in Recife, previously surprised Zika researchers with the disturbing proposal that this mosquito might be a stealth spreader of Zika. But two U.S. research groups tested the basic idea and couldn’t get the virus to infect the species.

Now, preliminary results from Ayres’ and two other research groups are renewing the discussion.

Congress Approves $1.1 Billion To Fight Zika

After nearly seven months of bickering and finger-pointing, Congress on Wednesday agreed to allocate $1.1 billion to help fight the spread and effects of the Zika virus.

The deal is part of a broader agreement to continue to fund the government after the fiscal year ends on Friday and the current budget expires.

It brings to an end a partisan fight that has had the unusual effect of delaying funding to deal with what all sides agree is a public health emergency.

CLICK HERE - The Lancet Infectious Diseases - Association between Zika virus infection and microcephaly in Brazil, January to May, 2016: preliminary report of a case-control study

abc.net.au - AFP - September 15, 2016

Scientists are warning that the world should prepare for a "global epidemic" of microcephaly, a birth defect where a baby's head is smaller than usual, as the Zika virus spreads to new countries.

Key points:

Researchers say microcephaly epidemic will spread to all countries with Zika

Scientists recommend Zika be added to list of congenital birth infections

Not all study babies with microcephaly had abnormalities show in brain scans

The warning comes after researchers in Brazil and Britain found further evidence to link the condition with Zika virus, a connection already widely accepted in medical circles.

"These babies do not catch up as they grow," says Dr. Antonia Augusto Moura da Silva of the Federal University of Maranhao, Sao Luis, Brazil.

He's describing the findings from a study of 48 babies whose mothers were believed to have been infected with the Zika virus. Forty-two of the children were diagnosed with microcephaly. The study, on the early neurological growth pattern of the infants, will be published in the journal Emerging Infectious Diseases in November but was released early online.

WHO - Zika Causality Statement - 7 September 2016

                                                  

who.int - 7 September 2016

Zika virus infection: update on the evidence for a causal link to congenital brain abnormalities and Guillain-Barré syndrome

Update of WHO Statement published on 31 March 2016

Since 2013, an unexpected rise in the number of reported cases of the neurological disorder Guillain-Barré syndrome2 (GBS) in French Polynesia, Brazil and other countries in the Americas led specialists to infer a link with an ongoing outbreak of Zika virus infection. Reports of unexpected increases in cases of microcephaly in north-eastern Brazil also led to the suggestion of a link to Zika virus infection in late 2015. On 1 December 2015, PAHO/WHO published an alert regarding the implications for public health of the detection of neurological syndromes and congenital malformations in the context of epidemic transmission of Zika virus in Brazil. On 1 February 2016, the World Health Organization (WHO) declared that the clusters of cases of microcephaly and neurological disorders occurring in areas with Zika virus transmission constituted a public health emergency of international concern.

We may see an increase in the incidence of mental illness, Parkinson’s and dementia.

wsj.com - by W. Ian Lipkin - September 6, 2016

Some four million children are born each year in the U.S., about half in areas where the mosquito species capable of carrying the Zika virus is found. If we assume that 3% of pregnant women in the U.S. will become infected over the next three years and at least 1% of children born to those mothers will be microcephalic, we can anticipate up to 20,000 microcephalic children. Humanitarian considerations aside, the estimated cost of caring for one such child over the course of his lifespan is $10 million.

Researchers have found that the Zika virus can live in eyes, and research in mice may help explain why some Zika patients develop eye disease, including a condition that can lead to permanent vision loss.

In a study published Tuesday in Cell Reports, researchers from Washington University School of Medicine in St. Louis describe the effect of Zika virus infections in the eyes of mouse fetuses, newborns and adults.

The study suggests that the eye could be a reservoir for the virus. Eye infection raises the possibility that people could become infected with Zika through contact with tears from infected people, they said.
