. . . "there's growing evidence that mosquitoes are developing resistance to the insecticide used in the nets.

Now the World Health Organization has just completed a 5-year, 5-country study looking into whether nets might be becoming less effective."

sciencedaily.com - American Association of Pharmaceutical Scientists - November 15, 2016

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.

How Ebola Adapted to Us

In December 2013, in a small village in Guinea, the Ebola virus left its traditional host—probably a bat—and infected a young boy. That leap triggered what became the largest Ebola outbreak in history. At first, the virus stayed within Guinea’s borders and, as in every previous epidemic, affected just a few hundred people.

yfile.news.yorku.ca - October 31, 2016

Vaccinating against dengue fever could increase outbreaks of Zika, suggests new research out of York University and Xi’an Jiaotong University in China.

The research identifies a potentially serious public health concern. More than a third of the world’s population lives in areas where dengue is endemic and cases of co-infection with Zika have already been reported.

18 October 2016 – Hurricane Matthew, which ripped through Haiti 13 days ago, has left more than 700,000 people in an “extremely difficult situation,” United Nations Special Adviser David Nabarro said today, and while steady progress is being made, led by Haitians themselves, the response must be accelerated as the needs are still great, frustrations are high, and access to hard-hit areas remains tough.

WHO Sending 1 Million Cholera Vaccine Doses to Haiti

           

Haitians wash clothes in a stream in Port-au-Prince. The widespread use of rivers has been linked to the country's deadly cholera outbreak.

cnn.com - by Ivan Watson, Tim Hume and Karla Pequenino - October 11, 2016

Jeremie, Haiti (CNN) - The World Health Organization is sending a million cholera vaccine doses to Haiti, it announced Tuesday, amid concerns over the rising number of cases in the aftermath of Hurricane Matthew.

WHO cholera expert Dominique Legros told reporters in Geneva that the UN's global public health body had decided Monday to send the vaccines to the hurricane-ravaged Caribbean nation, to attempt to prevent an outbreak of the waterborne disease.

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.

Miami's Zika Search Turns Up Another Virus: Dengue - NBC News // COMMENT ON MOSQUITO TRAP AND LAB TESTING NETWORK

Zika Working Group Comment: It is clear that there needs to be a much larger and more widespread mosquito trap network with linked DNA sequencing and analysis of mosquito and human health lab specimens. This is not only true for for Florida, but throughout the Gulf Coast region of the U.S. and up into Georgia and South Carolina. This trapping and testing network will need to grow over three years, starting in the current and anticipated hot spots.
