American mothers infected with the Zika virus last year were 20 times as likely to give birth to babies with birth defects as mothers who gave birth two years before the epidemic, federal health officials said on Thursday.

The Centers for Disease Control and Prevention concluded last April that Zika infection caused severe birth defects, including the abnormally small heads of microcephaly, but it had not previously estimated how common such defects were.

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.

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.

Mosquito-borne diseases like Zika can be extremely sensitive to climatic changes

The combination of climate change and last year’s El Niño phenomenon likely created the perfect playground for the Zika virus to spread rapidly across South America, a new study finds.

Both the Zika virus and the mosquitoes that carry it have been present in different parts of the world for a while. But several factors, including specific climatic conditions, could have catapulted the disease to public health emergency status, according to researchers from the University of Liverpool.

Impt CDC study shows rate of microcephaly related to Zika similar among babies born in US to est rate in Brazil. https://t.co/cdSLRliPuo

jamanetwork.com - December 13, 2016 - doi:10.1001/jama.2016.19006

In this report based on preliminary data for pregnant women in the USZPR with laboratory evidence of possible Zika virus infection, 6% overall had a fetus or infant with evidence of a Zika-related birth defect, and among women with timing of possible Zika infection exclusively during the first trimester, 11% had a fetus or infant with a birth defect. The birth defects primarily involved included microcephaly with brain abnormalities, such as intracranial calcifications. Preliminary estimates from the USZPR were within the range of 1% to 13% risk of microcephaly following first-trimester maternal Zika virus infection modeled on the outbreak in Bahia, Brazil, lending support to the credibility of these estimates.

Many of the children are suffering a plethora of difficulties including vision and hearing problems with doctors now labeling the overall condition as 'Congenital Zika Syndrome'.

Colombia, which suffered a Zika epidemic that peaked in February, has reported four times as many cases of babies born with microcephaly this year as it did in 2015, providing more proof that the Zika virus causes brain damage in infants.

Because births of microcephalic infants peaked five months after the epidemic did, at about nine times the numbers of the previous July, scientists feel sure that the greatest risk is to babies whose mothers were infected during their first trimesters or early in their second.

The numbers were reported in a study released Friday by the Centers for Disease Control and Prevention and conducted jointly by scientists from the C.D.C. and Colombia’s national health institute.

Working in the lab, UC San Francisco researchers have identified fetal brain tissue cells that are targeted by the Zika virus and determined that azithromycin, a common antibiotic regarded as safe for use during pregnancy, can prevent the virus from infecting these cells . . .

 . . . In the new study, published online Nov. 29, 2016, in the Proceedings of the National Academy of Sciences (PNAS), the UCSF researchers determined that the Zika virus preferentially infects brain cells with an abundance of a protein called AXL, which spans the outer cell membrane of several cell types and serves as a gateway for the invading virus . . .

It is the news that doctors and families in the heart of Zika territory had feared: Some babies not born with the unusually small heads that are the most severe hallmark of brain damage as a result of the virus have developed the condition, called microcephaly, as they have grown older.

The findings were reported in a study of 13 babies in Brazil that was published Tuesday in Morbidity and Mortality Weekly Report. At birth, none of the babies had heads small enough to receive a diagnosis of microcephaly, but months later, 11 of them did . . . 

 . . . The new study echoes another published this fall, in which three babies were found to have microcephaly later in their first year.

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.

Florida's utility industry steered more than $20 million of their profits into a failed constitutional amendment to impose new barriers to the expansion of rooftop solar energy generation, but developers say that as the cost of installing solar panels drops, the state could quickly become a leader in private solar energy expansion no matter what the energy giants do.

The Florida Solar Energy Industry Association estimates that over the next five years, Florida homeowners, businesses and utilities are projected to take advantage of the falling prices and install 2,315 megawatts of solar electric capacity — 19 times more than the amount of solar installed in the last five years.

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.
