THURSDAY, Jan. 12, 2017 (HealthDay Information) -- The primary case of domestically acquired Zika virus in a pregnant girl in the US didn't end in devastating beginning defects, docs report.

In a case research from the College of Miami, docs present new perception into the mosquito-borne virus, exhibiting fetal publicity does not essentially imply an infection.

The report additionally alerts docs to suspect Zika in sufferers who might have traveled to south Florida, not simply to areas outdoors the nation the place the virus is extra prevalent.

The toddler -- born full-term in October -- confirmed not one of the devastating beginning defects linked to Zika, akin to microcephaly (an abnormally small head and underdeveloped mind).

"Initially, every part with the child regarded positive," stated Dr. Ivan Gonzalez. He's co-director of the Zika response workforce on the College of Miami Miller Faculty of Medication, the place the mom and child have been sufferers.

As a result of the toddler was not contaminated with Zika, Gonzalez stays optimistic concerning the child's growth.

"Over time we're going to be taught that this child was simply uncovered, however not contaminated," he stated.

The case started final July. Within the 23rd week of being pregnant, the 23-year-old Florida girl developed a fever, widespread rash and sore throat adopted by muscle and joint ache. Blood assessments confirmed she had Zika.

Though her blood examined optimistic for Zika for six weeks, her being pregnant proceeded usually, in line with the report. Ultrasound examination confirmed no fetal mind abnormalities.

Docs proceed to observe the toddler due to studies that Zika-related developmental issues can come up within the months and years after beginning.

These issues embrace mind abnormalities with and with out microcephaly, neural tube defects and different mind malformations. Eye abnormalities and deafness may also end result, in line with the U.S. Facilities for Illness Management and Prevention.

The report was printed on-line Jan. 11 within the New England Journal of Medication.

Dr. Lucy Chen, a dermatologist on the college of drugs, was the primary to see the mother-to-be.

"I used to be consulted, as a dermatologist, to see a pregnant affected person with a rash. After testing a few of her blood, we came upon that she had Zika," Chen stated.

It was decided that the virus was acquired in Miami. Docs have been shocked that the an infection remained in her physique for six weeks. That is an instance of how the virus can flow into within the physique of a pregnant girl for greater than the everyday one to 2 weeks, the researchers stated.

The rash isn't unusual with Zika, however many physicians do not acknowledge it as a symptom of Zika, Chen stated. If a pregnant girl develops such a rash and is in an space the place Zika is lively, she ought to see her physician for a blood take a look at, she pressured.

Zika is transmitted by the Aedes aegypti mosquito. Florida's Miami-Dade County has the very best variety of domestically transmitted and travel-related Zika circumstances in the US.

However practically all the four,600 identified circumstances of Zika in the US concerned vacationers who visited areas in Latin America and the Caribbean, the place Zika is circulating, the authors of the report identified.

Nevertheless, neither this affected person nor her associate had left the US. Since her case, greater than 200 different circumstances of domestically acquired Zika have been recognized in the US, in line with the CDC.

So, what ought to docs search for?

"A rash is frequent for this sort of virus," stated Dr. Marc Siegel, a professor of drugs at NYU Langone Medical Heart in New York Metropolis.

"We see it rather a lot with dengue, and now we're seeing it with Zika," he stated, referring to a different mosquito-transmitted virus. "The issue with Zika is 80 p.c of the time there aren't any signs in any respect." Siegel was not concerned within the girl's case.

In line with the CDC, the proportion of infants with Zika-related beginning defects is analogous for contaminated pregnant girls who had signs and for many who did not -- about 6 p.c.

Gonzalez advises pregnant girls or girls contemplating being pregnant who're in Zika-affected areas to put on mosquito-protective garments and use insect repellent. Girls also needs to use secure intercourse practices as a result of Zika could be transmitted sexually.

The short motion of public well being officers saved Zika tamped down in Miami, Gonzalez stated. They educated the general public, examined mosquitoes and sprayed to eradicate mosquitoes that carry the virus.

"The affect is proscribed by our response time," Gonzalez stated. Now, in winter, mosquito exercise is low. However he expects exercise to flare up once more in April when temperatures rise in Miami.
