Notice to Readers: Changes in the Presentation of Zika Virus Disease, Non-Congenital Infection, and Addition of Zika Virus Congenital Infection to Notifiable Diseases and Mortality Table I

Weekly / May 27, 2016 / 65(20);524

The Executive Board of the Council of State and Territorial Epidemiologists has approved the additions of “Zika virus disease, non-congenital infection” and “Zika virus congenital infection” to the list of nationally notifiable conditions reportable to the National Notifiable Diseases Surveillance System (NNDSS) beginning in 2016 (1). Therefore, Zika virus disease, non-congenital infection data previously displayed for 2015 will no longer appear in Table I (Provisional cases of selected infrequently reported notifiable diseases [<1,000 cases reported during the preceding year], United States) of the MMWR Weekly Notifiable Diseases and Mortality Tables, because the condition was not considered nationally notifiable at that time. Instead, “NN” (not nationally notifiable) will appear in the 2015 column for total cases reported for previous years.

Additional Modifications to Table I

Data for Zika virus disease, non-congenital infection have been displayed under “Arboviral diseases” in Table I of the MMWR Weekly Notifiable Diseases and Mortality Tables since February 5, 2016 (2). These data will now be displayed in Table I as a separate condition in conjunction with Zika virus congenital infection. CDC and the U.S. States are still modifying the needed technical infrastructure to collect and transmit data for Zika virus congenital infections; the ability to receive and display this data are anticipated in early summer 2016. A Zika virus congenital infections heading is included in Table I now as a placeholder until the data become available to display.

The Zika virus disease data in Table I do not include data from the U.S. Territories, where most of the Zika virus disease cases are currently occurring. Therefore, Zika virus disease case counts displayed in Table I of the MMWR Weekly Notifiable Diseases and Mortality Tables will be different from case counts displayed in other reports that include data from U.S. Territories.
