Zika-affected pregnancies and birth defects in US
Must remain vigilant: CDC Acting Director
Centers for Disease Control and Prevention Acting Director Anne Schuchat stated: "Women in the US territories and elsewhere who have continued exposure to mosquitoes carrying Zika are at risk of infection. We must remain vigilant and committed to preventing new Zika infections."

CDC finds over 100 infants with Zika-associated defects
The study was conducted on 2,549 women with possible Zika infection who completed their pregnancies.
Among them, 1,508 had confirmed infection from 1 January 2016-25 April 2017.
122 pregnancies had resulted in Zika-related birth defects, including babies born with small heads, an irreversible condition called microcephaly.
Other birth complications included seizures, problems with movement, coordination, eating, and near constant crying.
Pregnant women urged to avoid Zika-affected areas
Zika virus can be spread by the bite of infected mosquitoes or sexual contact.
Pregnant women are advised to avoid Zika-affected areas as it is dangerous for them and their fetuses as well.
While Zika often causes no symptoms in adults, it may lead to fever, itchy rash, joint pains, and red eyes.
Birth defects include neural tube defects, eye abnormalities, and microcephaly.
Presence or absence of symptoms
Dr. Laura Riley, a specialist in high-risk pregnancies and infectious disease at Massachusetts General Hospital, stated: "The presence or absence of symptoms was not predictive of whether a baby would be damaged. There were women who had asymptomatic Zika whose babies were damaged."
