Researchers report Zika virus can threaten babies at any stage of pregnancy


Health officials said Friday that a case of Zika virus infection has been confirmed in a Missouri man who had traveled to Haiti, a known area of Zika transmission.

Google is also spreading intricate information involving Zika virus in 16 distinct languages.
Progenitor cells are like stem cells, only more specialized.
The virus, which can also be sexually transmitted, has been linked to microcephaly in the newborns of infected mothers.
Although this is an early study, it shows the mechanism by which the virus works in certain cells, he said.
Among the countries confirmed of having infected by the virus are Barbados, Bolivia, Brazil, Colombia, Curacao, Dominica Republic, Ecuador, El Salvador, French Guiana, Guadaloupe, Guatemala, Guyana, Haiti, Honduras, Martinique, Mexico, Nicaragua, Panama, Paraguay, Puerto Rico, Saint Martin, Surinam, Virgin Islands (United States) and Venezuela.
Global health officials are examining the connection between pregnant women contracting the virus and a birth defect called microcephaly in their newborn infants. Numerous infected cells died, and others showed disruption that could limit their ability to divide and flourish. The study was published on Friday in the journal Cell Stem Cell. “While this study doesn’t definitely prove that Zika virus causes microcephaly, it’s very telling that the cells that form the cortex are potentially susceptible to the virus, and their growth could be disrupted by the virus”.
Outside of pregnancy, Zika is normally no more threatening than a bad cold or a mild case of the flu. Since then, two U.S.-Brazilian studies have sought to confirm that the virus is responsible for the birth defect, and that it can also cause Guillain-Barr̩ syndrome Рa temporary paralysis Рin adults. It recommended pregnant women in any trimester consider postponing travel to the areas where the Zika virus transmission is ongoing.
Scientists not involved in the research welcomed the findings. “I do not think we will, but we will be prepared for it anyway”, Dr. Anthony Fauci, director of the US National Institute of Allergy and Infectious Diseases, said at an event presented by the Harvard T.H. Chan School of Public Health in collaboration with Reuters.
“This study is just the beginning, and many more studies are needed to understand the relationship between Zika and microcephaly“, commented Amelia Pinto, a professor of molecular microbiology and immunology at Saint Louis University.
There is no vaccine to prevent Zika virus infection.
