A new report from Brazil raises questions about whether the Zika virus can continue to damage an infected infant’s brain after birth.

An infant in Sao Paulo whose mother was infected late in her second trimester was born without any visible birth defects. But testing showed the baby had the Zika virus in his blood; the virus remained in his system for at least a couple of months.

At six months, it became apparent that the child had suffered Zika-related brain damage.

A report released on Tuesday shows in graphic detail the kind of damage Zika infections can do to the developing brain - damage that goes well beyond the devastating birth defect known as microcephaly, in which the baby's head is smaller than normal.

The current Zika outbreak was first detected last year in Brazil, where the virus has been linked to more than 1,800 cases of microcephaly, which can cause severe developmental problems.

Prior research has shown the Zika virus attacks neural progenitor cells - a type of stem cell that develops into different types of nerve or brain cells.

New research has found evidence the mosquito-borne virus can adversely affect cells necessary for replenishing damaged neurons.

Zika is understood to pose the greatest threat to pregnant women and their fetuses, which can be born with severe brain defects if infected with the mosquito-borne virus. But new research suggests Zika may damage adult brains, too, giving scientists another thread to follow in their attempts to understand the virus as the number of infections continues to rise in South America, the Caribbean, and elsewhere.

U.S. researchers have found evidence that a certain kind of brain cell present in newborns that remains in some amounts in adulthood can be susceptible to Zika infection, according to a study published Thursday in the journal Cell Stem Cell.

The Mystery of Zika’s Path to the Placenta

theatlantic.com - August 18th 2016 - Adrienne LaFrance

Among the many mysteries that have vexed scientists about the ongoing Zika epidemic is the question of how, in pregnant women, the virus manages to cross the maternal-fetal barrier.

A woman’s body is usually quite good at protecting her growing baby. There are biological blockades to prevent the transmission of viruses to a fetus through the bloodstream, by way of the placenta; the same path for the nutrients and oxygen that sustain a developing baby.

Puerto Rico Reports Elderly Victim Infected With Zika Dies

Associated Press - by Danica Coto - August 5, 2016

SAN JUAN, Puerto Rico (AP) -- Health officials announced Friday that an elderly person infected with Zika has died in Puerto Rico as the U.S. territory battles what federal authorities call a silent epidemic.

The victim was a 75-year-old man who was hospitalized and died from health ailments unrelated to Zika, according to Health Secretary Ana Rius. . . .

. . . The first Zika-related death was reported in late April and involved a 70-year-old man from the San Juan metro area. He suffered internal bleeding after developing a condition in which antibodies that formed in response to a Zika infection began attacking blood platelet cells. At the time, Rius said there were three other cases of the condition known as severe thrombocytopenia and that those patients recovered.

Playing Catch-Up With Zika

With the growing Zika outbreak in Florida, it's a dangerous mistake to continue underestimating the virus.

usnews.com - by Stephen S. Morse - August 1, 2016

We've seen it coming for months. Zika has been moving with hurricane intensity throughout South America and the Caribbean, appearing for the first time in 42 countries in the Western Hemisphere in less than two years. . . .

. . . We cannot afford to keep trying to catch-up every time another infection appears. . . .

. . . Zika is the infectious disease crisis now, but in our increasingly globalized and urban world, we can expect many more to come.

Keeping Zika Out Of Your Neighborhood

by Philip K. Stoddard, Ph.D. - Mayor of South Miami & Professor of Biological Sciences - Florida International University

Tactics for keeping out Zika

1. Keep Aedes aegypti from breeding in your house and yard by eliminating all standing water (see checklist on other side).

2. Keep Aedes aegypti out of your house. Window and screens should have no gaps or holes. Move and empty your pet’s water dish every day when they don’t need it.

3. Avoid getting bitten outdoors.

Insect repellants with DEET repel flying mosquitoes and prevent them from biting. Long sleeves and trousers help. Electric fans help – Aedes aegypti is a weak flyer and likes still air.

4. Don’t let your neighbors down.

One person can provide mosquitoes for the whole neighborhood by not taking the precautions listed here.

Florida Confirms 10 More Zika Victims; CDC Issues Notice to Pregnant Women

The CDC issued an advisory Monday that says pregnant women should not travel to a so-called Zika "transmission area" near Miami, the same day governor Rick Scott announced there are 10 new infections of the Zika virus likely transmitted by mosquitoes, bringing the total in the state to 14.

The governor called on the Centers for Disease Control and Prevention to activate an Emergency Response Team to assist the Florida Department of Health and other partners in their investigation, sample collection, and mosquito control efforts.

theguardian.com - July 31st 2016 - Joanna Walters

Senate Democrats have called for Congress to end its recess and immediately approve emergency funds for combating the Zika virus in America, after Florida reported its first cases of mosquito-borne infections on the mainland, and funding for mosquito nets for pregnant women started running low.

Near downtown Miami, teams of doctors were going door to door on Saturday to alert an estimated 30,000 residents, particularly pregnant women, of the risks of being bitten by local mosquitoes believed to be carrying the virus.

On Friday, Florida governor Rick Scott and the federal Centers for Disease Control and Prevention (CDC) confirmed that four new cases of the disease in the Miami area were almost certainly contracted through local insect bites.

Florida Health Officials Confirm Local Zika Transmission

submitted by Albert Gomez

           

cnn.com - by Debra Goldschmidt - July 29, 2016

(CNN) Four individuals in Miami-Dade and Broward counties have been infected with the Zika virus by local mosquitoes, Florida health officials said Friday.

These are the first known cases of the virus being transmitted by mosquitoes in the continental United States.

The unidentified individuals had not traveled to a Zika-affected area, had not had sexual contact with someone who had traveled to a place where the virus is circulating and had no other known exposure to the virus.

Brazil: Zika in House Mosquitos Requires 'Radical Change'

crofsblogs.typepad.com - g1.globo.com - July 24, 2016

Transmission of Zika by house mosquito requires 'radical change' in control measures

Biologist Constância Ayres, of Fiocruz Pernambuco, has made an unprecedented discovery that has the potential to provide a leap in scientists' knowledge of the Zika virus, and radically change the Brazilian strategy of preventing it.

Ayres succeeded in finding for the first time, mosquitoes carrying the virus in nature.

On Thursday, Fiocruz officially announced that the mosquito Culex quinquefasciatus, known as muriçoca or house mosquito, can also transmit the virus that causes microcephaly and malformations in babies.

Florida health officials said Tuesday they were investigating a possible case of Zika that wasn't carried back by a traveler.

If it's confirmed, it would be the first evidence that Zika has spread to mosquitoes in the continental U.S. All cases up to now have been in people who traveled to Zika-affected regions or their sexual partners.
