Contracting the virus in the third trimester has been thought to be less unsafe fetuses than in the first trimester, but this new case may invalidate this theory.

And that total will probably climb far higher by summer’s end, scientists predicted Wednesday.
Levin said the woman from Ventura County probably no longer has the virus and doctors doubt that she passed it on.
Zika is believed to be transmitted primarily through the bite of an infected mosquito, but sexual transmission is also possible.
“We will nearly certainly see more imported cases of Zika in our county”, he said, But, “since we do not have the mosquito vector in our (area) at this time, it is not likely that we will see cases that were acquired in our county”.
A case of Zika virus is confirmed in Ventura County.
Those worries may have been overstated, if the most recent World Health Organization report released Thursday is any indication.
“The finding may be important for women, not only pregnant women”, said Iwasaki.
Zika is known to cause a wide range of birth defects in humans including microcephaly, vision loss and joint problems.
Occasional individual cases of local transmission cropped up during earlier chikungunya and dengue outbreaks in Florida, but in most instances these did not amount to a new outbreak, Frieden explained.
Transmission sexually had the same effect as mosquito-borne infection, at least in the mice.
Charity Dean about the local situation and what precautions people should take. “That’s what we would anticipate seeing here”. “Ongoing surveillance is needed to determine the risk for sexual transmission of Zika virus infection from asymptomatic persons”, the researchers write.
Tomer Singer, director of reproductive endocrinology and infertility at Lenox Hill Hospital in NY, said the study “raises concerns about Zika becoming a sexually transmitted disease rather than just a virus that affects pregnant women”.
GSU Student Health Services also stressed, “At Georgia Southern, campus officials have been proactive in preparing for Zika and have already done an assessment of our campus to identify and remove areas that may collect standing water”.
Navy Medicine released Zika Virus Infection guidance in NAVADMIN 032/16, February 10, communicating force health protection measures and travel precautions to Navy and Marine Corps personnel.
It may sound like the plot to a bad Michael Crichton book, but mosquitos carrying the dreaded Zika virus have officially arrived in Florida, and infected men are now spreading it through their sperm. A resident of that state who visited Miami recently tested positive for the virus.
The finding set off a rush to expand lab capacity that continues as Zika’s foothold in the US expands.
Levin declined to give the woman’s name or age, but did say she was from the eastern portion of the county.
“In most of these cases, when something like this happens and a population is reduced or eliminated, something else moves in”, said Rey.
Choose a hotel or lodging with air conditioning or with screens on windows and doors.
In a new study published Thursday, researchers at Yale University found that Zika reproduced in the vaginas of pregnant mice four to five days after infection and that the virus spread from the vagina to the fetal brain.
No new countries or territories have reported local mosquito-born Zika infections since the WHO’s report last week, which is a first.

Pregnant women are urged to use condoms or abstain from sex if they live in or travel to areas where Zika is circulating, mainly in the Caribbean and Latin America. With other routes of infection, the Zika virus does not replicate unless you block type I interferons.
