Zika May Be Spread by Up to 35 Species of Mosquitoes, Researchers Say

           

The Aedes aegypti species of mosquito, pictured here, is believed to be the most capable transmitter of Zika. But University of Georgia ecologists have created a predictive model that suggests up to 35 species of mosquitoes can spread the virus, according to a study published Tuesday in the journal, eLife. Miami-Dade was the only county in Florida to have designated active Zika transmission zones during an outbreak in 2016, according to state health officials.

Zika may be spread by as many as 35 species of mosquitoes, including seven found in the United States, according to a forecasting model created by University of Georgia ecologists and published Tuesday in the journal eLife.

Most scientists, including those at the Centers for Disease Control and Prevention, believe Zika is primarily spread through the bite of an infected Aedes aegypti or Aedes albopictus species of mosquito, both of which are prevalent in Florida.

Children exposed to Zika virus in the womb may face complex health and developmental problems as they grow older, according to discussions at a National Institutes of Health workshop. A summary of the proceedings, authored by researchers from NIH's Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), is available in the latest issue of JAMA Pediatrics.

UTMB Scientists Uncover How Zika Virus Causes Microcephaly

           

utmb.edu - February 16, 2017

The findings are key to unraveling the mysteries of why the Zika virus causes birth defects

GALVESTON, Texas –A multidisciplinary team from The University of Texas Medical Branch at Galveston has uncovered the mechanisms that the Zika virus uses to alter brain development. These findings are detailed in Stem Cell Reports . . .

. . . Since a normal brain develops from simple cells called stem cells that are able to develop into any one of various kinds of cells, the UTMB team deduced that microcephaly is most likely linked with abnormal function of these cells . . .

. . . The researchers established a method of investigating how Zika alters the production, survival and maturation of brain stem cells using cells donated from three human fetal brains. They focused on the impact of the Asian lineage Zika virus that was involved in the first outbreak in North America in late 2015.

The Mission to Stop Ebola: Lessons for UN Crisis Response

CLICK HERE - International Peace Institute - The Mission to Stop Ebola: Lessons for UN Crisis Response (28 page .PDF report)

reliefweb.int - February 15, 2017
ADAM LUPEL AND MICHAEL SNYDER

Executive Summary

The Ebola epidemic of 2014–2016 was a fastmoving, multidimensional emergency that pre - sented unprecedented challenges for the multi - lateral system. In response to the outbreak, which was spreading exponentially in Guinea, Liberia, and Sierra Leone, Secretary-General Ban Ki-moon established the UN’s first-ever emergency health mission, the UN Mission for Ebola Emergency Response (UNMEER). UNMEER was mandated by the UN General Assembly in September 2014 to scale up and coordinate the activities of the UN presence on the ground working to stop the outbreak, which eventually claimed over 11,000 lives.

This report asks: Was UNMEER needed? Was it properly structured? Did it deliver? And what broader lessons can be learned from the experience of UNMEER for UN crisis response?

bbc.com - by James Gallagher - February 14, 2017

The majority of cases in the world's largest outbreak of Ebola were caused by a tiny handful of patients, research suggests.

The analysis, published in Proceedings of the National Academy of Sciences, shows nearly two thirds of cases (61%) were caused by 3% of infected people.

The young and old were more likely to have been "super-spreaders".

Why Killer Viruses Are On The Rise

       

Once called the "Dutchmen" because of their large noses and large bellies, proboscis monkeys live only in Borneo. Ecosystems that have a lot of diverse animals, like this monkey, also tend to have a lot of diverse viruses.  Charles Ryan

npr.org - by Michaeleen Doucleff and Jane Greenhalgh - February 14, 2017

The next troubling outbreak could come from a rain forest . . . And a big reason why: all the crazy animals that live here.

. . . Wild animals are now refugees. They have no home. So they come live in our backyards. They pee on our crops. Share our parks and playgrounds. Giving their viruses a chance to jump into us and make us sick.

"So it's really the human impact on the environment that's causing these viruses to jump into people," Olival says.

And cause an outbreak? I ask. Or a pandemic, says Olival.

Turning the Tide Against Cholera

nytimes.com - February 6th 2017 - Donald G. McNeil Jr.

Two hundred years ago, the first cholera pandemic emerged from these tiger-infested mangrove swamps.

It began in 1817, after the British East India Company sent thousands of workers deep into the remote Sundarbans, part of the Ganges River Delta, to log the jungles and plant rice. These brackish waters are the cradle of Vibrio cholerae, a bacterium that clings to human intestines and emits a toxin so virulent that the body will pour all of its fluids into the gut to flush it out.

TEMPO.CO, Rio de Janeiro - The Brazilian government announced Friday that the number of confirmed deaths caused by a yellow fever outbreak has reached 60, while 87 more suspicious deaths are being investigated.

In a statement, the Health Ministry said that 53 of the deaths had come in the state of Minas Gerais, where the outbreak started before spreading to other states. Four people have died in Espirito Santo and three more in the state of Sao Paulo.

Since the start of the outbreak, 150 deaths were potentially attributed of yellow fever, 60 of which have been confirmed, 87 are still under investigation and three have been eliminated.

In total, 921 people have been suspected of being infected, 804 of which happened in Minas Gerais. 702 are being investigated, 161 have been confirmed and 58 have been ruled out.
