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

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.

Mosquito Collection Tests Positive for West Nile Virus in Orange County

kfdm.com - by Staff - August 12, 2016

From Orange County Mosquito Control District:

Orange County Mosquito Control District has been informed by the Texas Department of Health that a collection of mosquitoes from Orange County tested positive for West Nile virus. The mosquitoes testing positive for WNV were collected on August 2nd from an area on the west side of the County - North of IH-10, East of HWY 105, West of Doty Rd. and South of Sawmill Rd., in Vidor. This is the 1st sample of mosquitoes testing positive for the West Nile virus in Orange County in 2016. This information tells us that the virus is cycling between the birds and the mosquitoes in the area. So, it is important for everyone to take personal protective measures to protect themselves from mosquito bites regardless of what area it is that they live in throughout the county. Currently, West Nile virus activity in Texas is as follows: Mosquitoes Collections 903, Bird’s 1, Horses 4, Humans 37, Total 945. West Nile virus activity has been detected in 26 counties in Texas so far this year.

Treatments in the area have been increased and we are following up with additional mosquito collections and the testing of samples from the area to determine whether or not viral activity still exists. These procedures will continue until we receive negative results from the T.D.H. labs.

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.

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.

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.

Bridge City residents informed of contaminated water

kfdm.com - by Ashley Devriend - July 31, 2016

BRIDGE CITY — Joe Brody is one of the thousands of Bridge City residents receiving this letter over the weekend from the city.

It notifies him the Texas Commission on Environmental Quality notified the city drinking water exceeded maximum contaminant levels for a group of volatile organic compounds. . . .

. . . The letter states some who drink water with excess levels of the compound over many years may experience problems with their liver, kidney, or central nervous systems and may have an increased risk of getting cancer.

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.
