Zika outbreak: How does the Zika virus damage the brain? - TomoNews

PULLMAN, WASHINGTON — Three new experiments studying how Zika affects a developing fetus could provide proof of a causal link between the outbreak in Brazil and the spate of birth defects in babies that followed. The Los Angeles Times reports that the mosquito-borne Zika virus has been linked to a severe birth defect in babies called microcephaly, characterized by an abnormally small head. Thus far, most research on the virus has focused on the damage it inflicts on newborns. Now, scientists are using mice to better understand how exactly Zika damages the brain. A Washington State University research team found that the virus, when injected into pregnant mice, preferentially target the placenta, damaging it and using it to leak into the fetus. Another study found that Zika virus cells tend to be attracted to cells in the brain. Once they've crossed the placenta, they travel to the brain and infect neural progenitor cells, responsible for building a significant portion of the brain. The virus turns these healthy cells into viral factories that keep producing the virus until they explode and in turn infect other cells. The lack of neural progenitor cells means the brain does not fully develop, according to NPR. When the virus was directly injected into the brains of growing mice embryo, scientists discovered that they developed structural abnormalities in three to five days. The abnormalities were similar to those seen in babies with microcephaly. The BBC reports that the findings from the three published studies are significant but not conclusive, since tests were done on mice and not on pregnant humans. Scientists believe further research, as well as testing on larger animals such as monkeys — which are more similar to humans — may be more helpful. ----------------------------------------­--------------------- Welcome to TomoNews, where we animate the most entertaining news on the internets.

Zika Virus Outbreak: What You Should Know

Zika Virus Outbreak: What You Should Know

Mosquitoes in tropical areas are causing an outbreak of a frightening disease called the Zika virus. We’ve never given this virus much attention before, since Zika will only give you mild symptoms like a fever, rash, and headaches. In fact, most people won’t even know they have it. But it’s a different story if you’re pregnant – or planning to become pregnant. The virus may cause a serious birth defect called microcephaly, where a baby’s head and brain are much smaller than normal. It can be fatal or cause severe developmental problems. Get answers to more of your questions about how Zika is spread, what the symptoms are, who's at risk, and how you can protect yourself, here: http://wb.md/218N9Ky

Babies of infected mothers can be born with underdeveloped brains, deafness and blindness. "Daily life is exhausting" says 16-year-old Leticia, who cares full-time for her son. "The population is huge, so why are only the poor affected?" asks Danielle, who was bitten during pregnancy. At a time of recession, and as the virus spreads in the favelas, it becomes clear that poverty is the key component to Brazil's Zika crisis.

Monsanto To Blame? Zika Virus Conspiracy Theory Explained

A group of Argentine physicians have publicly questioned the cause of the outbreak of microcephaly in Brazil, is it the Zika virus or something else? The group is claiming that Monsanto is to blame for the outbreak NOT the Zika virus. Cenk Uygur, host of The Young Turks breaks it down. Tell us what you think in the comment section below. Read more here: http://www.techtimes.com/articles/133548/20160214/monsanto-larvicide-not-zika-virus-true-cause-of-brazils-microcephaly-outbreak-doctors.htm "The microcephaly outbreak in Brazil, which coincided with the spread of the Zika virus, continues to stun the world, even months after the incident was first reported. Pregnant women all over the world have been advised to take caution. The Zika virus infection has been linked to newborn babies with the birth defect microcephaly. This is a congenital condition in which babies are born with unusually tiny heads. The notion, however, has recently been challenged by a group of Argentine physicians. The group suspects that the Zika virus is not to blame for the rise in microcephaly cases, but that a toxic larvicide introduced into Brazil's water supplies may be the real culprit. According to the Physicians in Crop-Sprayed Towns (PCST), a chemical larvicide that produces malformations in mosquitoes was injected into Brazil's water supplies in 2014 in order to stop the development of mosquito larvae in drinking water tanks.”*

Zika in America: Health officials on standby for outbreaks of Zika virus in the U.S. - TomoNews

ATLANTA — Health officials are bracing for outbreaks of the Zika virus in the continental United States this summer as warmer weather signals the start of the mosquito season. The Centers for Disease Control and Prevention will send rapid response teams to any community where the Zika virus is transmitted locally, according to the CDC’s draft interim response plan for the Zika virus. Infection with the virus in pregnant women causes the birth defect microcephaly and other severe brain abnormalities in babies. The CDC will monitor Zika cases by determining the travel and sexual history of patients, and whether they are pregnant. Capacity will be increased for laboratory testing, with testing times reduced to help determine how widespread Zika is in any area. Vector controls of mosquitoes will also be increased, depending on the severity of the outbreak. Blood donations will be monitored in Zika-affected areas and supplies for transfusions brought in from non-affected regions. Meanwhile, response teams will open lines of communication with the public and advise of any areas that pregnant women should avoid. Southern U.S. states such as Mississippi, Texas and Florida that are home to the Aedes aegypti mosquito, which is the primary vector for Zika, have the highest risk of an outbreak, according to a Washington Post report. However, officials do not expect an explosion of cases in the mainland U.S. due to a higher prevalence of air-conditioning and window screens, and a population that is more widely spread out than in densely populated areas of South America where Zika has taken hold. ----------------------------------------­--------------------- Welcome to TomoNews, where we animate the most entertaining news on the internets.
