HealthDay News — A total of 5168 noncongenital Zika virus disease cases were reported from US states and the District of Columbia in 2016, with 95% of cases identified in travelers returning from Zika virus-affected areas, according to research published in the US Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report.
Victoria Hall, DVM, from the CDC in Atlanta, and colleagues reviewed data on noncongenital Zika virus disease cases with symptom onset during January 1 to December 31, 2016, in the 50 US States and the District of Columbia.
The researchers identified 5168 noncongenital Zika virus disease cases from the US states and District of Columbia in 2016.
Ninety-five percent of the cases were identified in travelers returning from Zika virus-affected areas, with the most common travel destination the Caribbean (61% of cases). Overall, 4% of cases were acquired through presumed local mosquito-borne transmission; 1% were acquired through other routes, primarily sexual transmission.
“It is important that providers in the United States continue to test symptomatic patients who live in or recently traveled to areas with ongoing Zika virus transmission or had unprotected sex with someone who lives in or traveled to those areas,” the authors wrote.
