CDC has updated its interim guidelines for U.S. health care providers caring for pregnant women during a Zika virus outbreak ( 1 ). (cdc.gov)
Updated guidelines include a new recommendation to offer serologic testing to asymptomatic pregnant women (women who do not report clinical illness consistent with Zika virus disease) who have traveled to areas with ongoing Zika virus transmission. (cdc.gov)
This update also expands guidance to women who reside in areas with ongoing Zika virus transmission, and includes recommendations for screening, testing, and management of pregnant women and recommendations for counseling women of reproductive age (15-44 years). (cdc.gov)

Researchers at the University of Wisconsin-Madison have confirmed that a benign bacterium called Wolbachia pipientis can completely block transmission of Zika virus in Aedes aegypti , the mosquito species responsible for passing the virus to humans. (scienceblog.com)
Matthew Aliota, a scientist at the UW-Madison School of Veterinary Medicine (SVM) and first author of the paper - published today (July 1, 2016) in the journal Scientific Reports - says the bacteria could present a "novel biological control mechanism," aiding efforts to stop the spread of Zika virus. (scienceblog.com)
There are not yet any approved Zika virus vaccines or antiviral medications, and ongoing mosquito control strategies have not been adequate to contain the spread of the virus. (scienceblog.com)
Zika virus belongs to the same family as dengue virus and Aliota and Osorio - with co-authors Stephen Penaido at SVM and Ivan Dario Velez, at the Universidad de Antioquia in Medellin, Colombia - asked whether Wolbachia -harboring Aedes aegypti may also be effective against Zika virus. (scienceblog.com)
They were also interested in studying the mechanisms behind Zika virus infection and transmission in mosquitoes. (scienceblog.com)
In the study, the team infected mice with Zika virus originally isolated from a human patient and allowed mosquitoes from Medellin to feed on the mice either two or three days after they were infected. (scienceblog.com)
The mosquitoes were either harboring the same strain of the Wolbachia bacteria (called wMel) used in field studies or were Wolbachia -free and the mice had levels of virus in their blood similar to humans infected with Zika virus. (scienceblog.com)
An additional group of mosquitoes, both wild-type and Wolbachia -infected, was allowed to feed instead from a membrane containing sheep's blood spiked with a high concentration of Zika virus, per other standard laboratory studies. (scienceblog.com)
Four, seven, 10 and 17 days after the mosquitoes fed on Zika-virus-infected blood the researchers tested them for Zika virus infection, assessed whether the virus had disseminated - or spread to other tissues in the mosquito, and examined whether the virus made its way to the mosquito saliva, where it must be present to be transmitted. (scienceblog.com)
They found that mosquitoes carrying Wolbachia were less likely to become infected with Zika virus after feeding on viral blood, and those that were infected were not capable of transmitting the virus in their saliva. (scienceblog.com)
Mosquitoes with Wolbachia were less capable of harboring Zika virus, and though they do get infected with Zika, it is to a lesser extent than wild-type mosquitoes. (scienceblog.com)
