Zika Virus Spread to New Areas Causes New Health Concerns ― Region of the Americas, May 2015–January 2016
Zika virus is a mosquito-borne flavivirus transmitted primarily by Aedes aegypti mosquitoes. Most infections are asymptomatic, and symptomatic disease generally is mild. In May 2015, the first local transmission of Zika virus in the Americas was reported in Brazil. Following the spread of Zika virus in Brazil, there was a marked reported increase in the number of infants born with microcephaly; it is not known how many of these cases are associated with Zika virus infection. By mid-January 2016, local Zika virus transmission had been identified in 20 countries or territories in the Americas; spread to other countries in the region is likely. While local transmission of Zika virus has not been documented in the continental United States, infections have been reported among travelers visiting or returning to the United States, and these likely will increase. Imported cases may result in local transmission in limited areas of the continental United States. The best way to prevent Zika virus infection is to avoid mosquito bites. Until more is known, pregnant women should consider postponing travel to any area with ongoing Zika virus transmission. Health care providers should contact their state or local health department about testing patients with symptoms of Zika virus infection and a compatible travel history.
Possible Association Between Zika Virus Infection and Microcephaly In Brazil
In early 2015, an outbreak of Zika virus, a flavivirus transmitted by Aedes mosquitoes, was identified in northeast Brazil, an area where Dengue virus was also circulating; by September, reports of an increase in the number of infants born with microcephaly in Zika virus-affected areas began to emerge, and Zika virus RNA was identified in the amniotic fluid of two women whose fetuses had been found to have microcephaly by prenatal ultrasound. The Brazil Ministry of Health has begun investigating the possible association of microcephaly with Zika virus infection during pregnancy. Among 35 infants with microcephaly born during August–October 2015 in eight of Brazil’s 26 states, the mothers of all 35 had lived in or visited Zika virus-affected areas during pregnancy, 25 (74%) infants had severe microcephaly (head circumference >3 standard deviations below the mean for gestational age), and 17 (49%) had at least one neurological abnormality. Among 27 infants who had neuroimaging studies, all had abnormalities. None of these infants has been tested for Zika virus infection. Further studies are needed to confirm the association of microcephaly with Zika virus infection during pregnancy and to understand any other adverse pregnancy outcomes associated with Zika virus infection. Pregnant women in Zika virus-affected areas should protect themselves from mosquito bites by using air conditioning or screens when indoors, wearing long sleeves and pants, and using insect repellents when outdoors. Most repellents, including DEET, can be used on children aged >2 months. Pregnant and lactating women can use all Environmental Protection Agency (EPA)-registered insect repellents according to the product label.[/TD]
