Scientists confirmed in a take a look at posted April 13 that the virus can certainly cause microcephaly and brain damage in babies.

Microcephaly can also result from some of other factors, including chromosomal abnormalities, reduced oxygen to the fetal mind, excessive malnutrition, and fetal infections all through pregnancy.

formerly, Brazil saw about one hundred fifty instances of microcephaly every yr. but considering the fact that October, coinciding with the upward push of Zika, the united states of america has pronounced extra than five,000 suspected instances, many of which have been related to recognized Zika infections of their mothers.

evidence helping the link consists of lines of Zika virus observed in samples of blood and fetal tissue, such as the brains of infants in Brazil who died of microcephaly.

"there is a lot we do not know. are we able to say each mother who has Zika virus will have a infant with microcephaly? No. We do not know why this baby receives microcephaly and that child would not," Dr. Oluwatosin Goje, an Infectious ailment OB/GYN at the Cleveland clinic, informed CBS information. certainly, many women in Brazil went on to have healthful infants no matter the outbreak.

Zika has additionally been linked to miscarriages. The CDC said in February that  U.S. women who had shrunk the virus even as touring overseas miscarried after returning home. Zika virus become observed in their placentas.

"With infections in standard all through being pregnant, there may be a danger of miscarriage," Goje defined. "different infections that could motive miscarriage consist of toxoplasmosis, rubella, and cytomegalovirus, and in many instances relying on how early the infection is gotten smaller, some human beings may also have a miscarriage. one of the things that researchers are analyzing is the suspicion that having shriveled the Zika virus inside the first trimester can be extra adverse in comparison to the second or 0.33 trimester, so that would explain the miscarriages in some people."

what's the risk of journey to Zika-affected regions?

The CDC has issued a journey advisory urging ladies who are pregnant or thinking of turning into pregnant to avoid tour to places wherein Zika is actively spreading.

those regions encompass:

•           In Latin america: Bolivia, Brazil, Colombia, Costa Rica, Ecuador, El Salvador, French Guiana, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, Paraguay, Suriname and Venezuela.

•           inside the Caribbean: Barbados, Curacao, the Dominican Republic, Guadeloupe, Haiti, Jamaica, Martinique, St. Martin, Puerto Rico, the U.S. Virgin Islands.

•           Cape Verde, off the coast of western Africa.

•           American Samoa, Samoa and Tonga within the South Pacific.

"we are no longer saying delay tour indefinitely, however at the least preserve off on spring and summer travel plans to these areas until the CDC knows more about the virus," Goje stated.

If travel is vital, health officials endorse taking extra precautions to keep away from mosquito bites, along with carrying lengthy-sleeve shirts and lengthy pants, staying interior with air conditioning or defensive displays, and the use of Environmental safety agency (EPA)-registered insect repellents, inclusive of those containing DEET, Picaridin or a combination.

What form of trying out is available in the U.S.?

Goje stated a handful of her very own sufferers and plenty of others stated her by colleagues have currently travelled to areas in which Zika is spreading. amongst these girls, anxieties are strolling high.

"most patients are concerned and they need to recognise more, specially about microcephaly," she stated.

A blood check is to be had for pregnant girls who have lately traveled to Zika-affected areas, whether or not they may be displaying signs of contamination or no longer. but, because there may be no business diagnostic test available, all samples ought to undergo the CDC and results can take weeks to return lower back.

whilst the take a look at may be administered at any point at some point of being pregnant, it's miles high-quality to peer a medical doctor as soon as possible, as the virus clears the blood gadget in approximately per week.

Pregnant girls who assume they may be inflamed and are experiencing signs like fever, joint ache, rash, and conjunctivitis need to are looking for scientific interest right away.

Goje said efforts are being made to make Zika trying out more widely to be had at kingdom degree.

As some distance as microcephaly, the condition can usually be picked up in an ultrasound between 18 and 20 weeks, Goje stated, "but this is not set in stone." some cases can be missed this early on and might not be detected till the late 2nd trimester or early 1/3 trimester. "So if a patient has traveled to an area in which Zika transmission is ongoing, it's essential to get an ultrasound among 18 and 20 weeks, but it's also essential to get follow-up ultrasounds," Goje said.

What should I realize approximately Zika and sexual transmission?

There have been numerous cases of Zika virus being transmitted via sexual touch with an inflamed person.

in keeping with the CDC, Zika may be found in semen for up to 10 weeks after the onset of illness, but it is unknown if the virus can persist in semen for longer than that or if infected men who in no way develop signs and symptoms can transmit Zika to their intercourse partners.

Will Zika spread inside the U.S.?

to date, there were no cases of local transmission of Zika virus through mosquitoes within the continental usa, but experts warn it is able to show up.

The Aedes aegypti mosquito -- the species that spreads Zika -- is frequently found in southern states, so as more infected vacationers return domestic, mosquitoes here should chunk them, choose up the virus, and transmit it to others. The mosquitoes are lively in a wider place of the usa in hotter months, so the danger could growth in spring and summer season.

ninety nine million travelers departed from major Brazilian airports for global destinations from Sept. 2014 to Aug. 2015. extra than 2.7 million of them traveled to the U.S. The circles in this map suggest regions with extra numbers of tourists from Brazil. regions shaded in yellow have mosquitoes that would transmit Zika virus during warmer months, at the same time as areas in orange have them 12 months-round.

however, whilst professionals say that some local transmission might be inevitable, they do not anticipate substantial outbreaks here.

"we have  matters going for us. First, the mosquitoes are not gift in any respect in most of the usa and they are found in an awful lot lower numbers in which they are gift," CDC Director Dr. Thomas Frieden advised "CBS night news."

specialists say several other factors will help keep Zika at bay inside the U.S., which includes much less dense urban areas than South and imperative the us, get admission to to aircon and protecting monitors, and overall better mosquito control.

nonetheless, as the weather warms and mosquitoes emerge as extra present, everyone can take steps to discourage any outbreaks by way of getting rid of status water in locations like uncovered packing containers and bottles, rubbish cans, old tires, and flower pots, in which mosquitoes like to breed, and via using insect repellent to lessen the threat of having bitten.
