More evidence that Zika will continue to attack the brain cells. Adults who get bitten are going to be in for surprise down the road.
More Bad Zika News: Affected Newborn Stayed Infected for Two Monthsby Maggie Fox A Brazilian baby with brain damage caused by Zika virus stayed infected for more than two months after he was born, doctors reported Wednesday. That suggests that newborns may continue to be at risk from the virus at a time when their brains are still rapidly growing and developing. It's another unpleasant surprise about Zika, the once-uninteresting virus that keeps throwing curveballs at researchers. The baby already had brain damage from the virus, which can infect a growing fetus and which appears to head straight for developing nerve cells. Related: Zika May Affect Adult Brains, Too But the virus continued to actively infect him after he was born, Danielle Oliveira of the University of Sao Paulo and colleagues wrote in a letter to the New England Journal of Medicine. "On Jan 2, 2016, a male child was born with microcephaly in Sao Paulo, Brazil, at 40 weeks of gestation to a mother who reported having symptoms associated with Zika virus infection during the 26th week of pregnancy," they wrote. Magnetic resonance imaging showed the baby boy had brain damage. Nearly two months after he was born, the baby's blood, saliva and urine all tested positive for Zika. Two weeks later, 67 days after he was born, the baby's blood still had evidence of Zika virus - not antibodies to the virus, but the virus itself. Seven months later, the blood was clear and the baby had antibodies to Zika. "When the infant was examined on day 54, he had no obvious illness or evidence of any immunocompromising condition," they wrote. An immune condition might explain a prolonged infection. He was developmentally delayed: floppy, uncoordinated for his age and he had cerebral palsy. The mother had developed a characteristic Zika rash 26 weeks into her pregnancy — in the third trimester. That's bad news. Doctors know the earlier in pregnancy a woman is infected, the worse the damage. This finding, and others, show the developing baby is never safe from the virus. The father had traveled to Brazil's Zika-hit northeastern region a few weeks before and had similar symptoms then. The team suspects he infected his wife sexually. As far as doctors knew, Zika clears up after a week or so. They knew it could cause long-lasting infections during pregnancy because there have been cases where a mother showed evidence of Zika for months after her own infection cleared up. Doctors believe it shows the fetus is infected, and sending bits of virus back into the mother's system through the placenta. The virus is also known to stay in a man's semen for months. http://www.nbcnews.com/storyline/zika-virus-outbreak/more-bad-zika-news-affected-newborn-stayed-infected-two-months-n637326 |

Ban news. Even though a baby may be born without symptoms, they may still be effected with potential nerve damage as time goes on. Zika is becoming a monster.
Zika virus' effects are broader than first thoughtThe Zika virus is primarily known to cause microcephaly (small heads) in the babies of infected mothers, but its effects may be wider-ranging than first thought. A Harvard-led study has conducted brain scans of 45 Brazilian babies from Zika-stricken mothers, and the data suggest that even those children born without conspicuous problems may suffer later on. Ultimately, Zika is disrupting brain development -- microcephaly is a frequent result of that, but there can also be issues around the cortex (which is crucial to coordination and memory) that show up first and may only materialize on the outside as the child grows. Moreover, Zika can damage nerves in such a way that it forces arms and hands to contract. The virus is even deceptive at times. As it can prevent brain cavities from properly draining cerebrospinal fluid, you may get the false impression that some fetuses are normal when they're really victims of Zika-related bloat. There's a real risk that the cavities can burst and collapse the brain. The scans will help make sense of how Zika behaves, and could also help with critical decisions. Parents may learn about a fetus' fate early enough to decide whether or not they want to carry it to term. At the same time, it could offer hope to parents by revealing when a fetus is untouched -- if those early warnings signs don't appear, the family might rest that much easier. Although wider studies are necessary to get the full scope of what's happening (one just started with 10,000 babies), this is an important start. |

This is really bad who is going to educated thousands of children who have microcephaly. I work in a school and have friends working in other schools and resources are stretched now. CDC needs to come up with a vaccine.

A lot of unknowns. There won't be a way to educate them, and I also don't believe they will survive to adulthood if memory serves me right.
Who is going to take care of the adults who are bitten and who begin to develop Alzheimer's and various nerve disorders. |

Now this all is scarring me. It raises a huge problem that is not really been addressed adequately now. This is hitting home because I am caring for someone with a neurological degenerative disease, but the progression (regression???) is very slow. In this case there is an underlying genetic fault, but there is huge variation within the family as to how it manifests. It is now 8+ years since the person was diagnosed, but her brother (with the same gene fault) died within 3 years. The brain is complex and even affecting slightly different areas can lead to huge differences in how it progresses. Zika hitting children saddens me, but this potential long term affect in adults really scares me (maybe because it is hitting too close to my daily reality). |

There are numerous studies coming out that are game changers, as cobber put it. Now we have a case of Zika spreading sexually from person to person and by those with no symptoms (see link). It's my belief that this information (new studies) was withheld until after the Olympics.
