2016 Zika Virus
NEW: MMWR: Baseline Prevalence of Birth Defects Associated with Congenital Zika Virus Infection—Massachusetts, North Carolina, and Atlanta, Georgia, 2013–2014
CDC used data from population-based birth defects surveillance programs to assess the prevalence of birth defects during 2013–2014 that met the surveillance case definition for birth defects potentially related to Zika virus infection, before introduction of Zika virus into the United States. After introduction of Zika virus, the proportion of infants and fetuses with birth defects born to mothers with laboratory evidence of possible Zika infection reported by the US Zika Pregnancy Registry during January 15–September 22, 2016, was approximately 20 times higher than the prevalence of potentially Zika-related birth defects among pregnancies during the pre-Zika years.
NEW: EID Journal Article: Estimated Incubation Period for Zika Virus Disease
New data reported by the Centers for Disease Control and Prevention (CDC) suggest that the incubation period for Zika virus—or the time between infection and showing symptoms—is estimated at 3-14 days. Until this point, the incubation period has not been well-defined and was previously established based on incubation period of similar arboviral diseases. CDC used data from 197 US travelers to areas with Zika, were likely infected by mosquito bite and who had signs and symptoms of Zika following their visits to estimate the incubation period.
NEW: EID Journal Article: Use of Blood Donor Screening Data to Estimate Zika Virus Incidence, Puerto Rico, April–August 2016
CDC evaluated blood donation screening data collected by two of Puerto Rico’s largest blood centers and estimates 469,321 people in Puerto Rico, approximately 12.9% of the population, were infected with Zika from April-August 2016. Results from blood donation screening during outbreaks can add to what is known about Zika through routine clinical and surveillance data and improve targeting of public health prevention and response efforts.
Key Messages – Zika Virus
A collection of the most up-to-date and cleared information on the ongoing Zika virus outbreak.
Print Resources in Different Languages
CDC fact sheets and posters for distribution to patients are available in languages, including Spanish, Arabic, Tagalog, Vietnamese, Mandarin, Creole, and Korean. These resources cover a variety of topics, including travel information, insect repellent, sexual transmission, and mosquito control.
Clinicians Caring for Pregnant Women and Women of Reproductive Age
Pregnancy and Zika Testing
The interactive clinical algorithm allows healthcare providers to receive recommendations tailored to their pregnant patients with possible Zika exposure. Healthcare providers can answer questions about pregnant patients and, based on the responses, receive information regarding the type of testing indicated as well as clinical management recommendations. It can be used on computers and mobile devices/tablets.
U.S. Zika Pregnancy Registry
CDC and state, tribal, local, and territorial health departments request that healthcare providers, especially obstetric and pediatric healthcare providers, participate in the US Zika Pregnancy Registry.
Clinicians Caring for Infants and Children
Advice For People Living In or Traveling to Brownsville, Texas
On December 14, 2016, CDC issued guidance related to Zika for people living in or traveling to Brownsville, Cameron County, TX and has designated Brownsville as a Zika cautionary area (yellow area).. On November 28, the Texas Department of State Health Services reported the state’s first case of local mosquito-borne Zika virus infection in Brownsville. Additional cases of mosquito-borne Zika have been identified in the area, suggesting that there is a risk of continued spread of Zika virus in Brownsville.
Advice for People Living in or Traveling to South Florida
On December 9, 2016, CDC removed the red area designation for the remaining 1.5-square-mile area of South Miami Beach after three mosquito incubation periods (45 days) passed without any new locally transmitted cases of Zika. Guidance for yellow areas now applies to the South Miami Beach area and all of Miami-Dade County.
Clinical Evaluation and Testing
Guidance for U.S. Laboratories Testing for Zika Virus Infection
The guidance was updated to be inclusive of the currently available Emergency Use Authorization (EUA) assays; it takes into account the recent updates to the CDC Trioplex Real-time RT-PCR Assay EUA, which includes the addition of whole blood as an acceptable specimen type. The updated guidance also specifies that plaque reduction neutralization testing (PRNT) confirmation is currently not routinely recommended in Puerto Rico, where dengue is endemic.
Clinical Evaluation & Disease
Zika virus is transmitted to humans primarily through the bite of an infected Aedes species mosquito. The most common symptoms of Zika virus disease are fever, rash, joint pain, and conjunctivitis. Most people infected with Zika virus are asymptomatic. Characteristic clinical findings are acute onset of fever with maculopapular rash, arthralgia, or conjunctivitis. Other commonly reported symptoms include myalgia and headache.
Testing for Zika Virus
Contact your state or local health department to facilitate testing.

CDC U.S. Zika Pregnancy Registry Healthcare Provider Toolkit for Health Departments
This toolkit is a suite of tools and resources to help health departments educate and inform healthcare providers to identify, counsel, report, and follow infants born to pregnant women with laboratory evidence of Zika virus infection. We invite you to use this toolkit to raise awareness about the U.S. Zika Pregnancy Registry and improve reporting and completeness of data collected.

Interim CDC Zika Response Plan
The purpose of this document is to describe the CDC response plan for the first locally acquired cases of Zika virus infection in the continental United States and Hawaii.
Zika Community Action Response Toolkit (Z-CART)
The Z-CART outlines an approach to risk communication and community engagement planning and is intended as a template for state, local, and tribal agencies to adapt to their needs and to use for reviewing plans for communicating about Zika during the event of a locally transmitted Zika virus.

Current Travel Warnings – February 22 (US Department of State)
The U.S. Department of State issues Travel Warnings when long-term, protracted conditions make a country dangerous or unstable. Travel Warnings recommend that Americans avoid or carefully consider the risk of travel to that country. The State Department also issues Travel Warnings when the U.S. Government’s ability to assist American citizens is constrained due to the closure of an embassy or consulate, or because of a drawdown of State Department staff.
Food, Drug and Device Safety
NEW: Multistate Outbreak of Listeriosis Linked to Soft Raw Milk Cheese Made by Vulto Creamery
CDC is collaborating with public health and regulatory officials in several states, and the U.S. Food and Drug Administration (FDA) to investigate a multistate outbreak of Listeria monocytogenes infections (listeriosis). Six people infected with the outbreak strain ofListeria have been reported from four states since September 1, 2016. A list of states and the number of cases in each can be found on the Case Count Map page. Whole genome sequencing performed on clinical isolates from all six ill people shows that the isolates are closely related genetically. This close genetic relationship provides additional evidence that people in this outbreak became ill from a common source.
NEW: Multistate Outbreak of Shiga toxin-producing Escherichia coli O157:H7 Infections Linked to I.M. Healthy Brand SoyNut Butter
CDC is collaborating with public health and regulatory officials in several states and the U.S. Food and Drug Administration (FDA) to investigate a multistate outbreak of Shiga toxin-producing Escherichia coli O157:H7 (STEC O157:H7) infections. Epidemiologic evidence available at this time indicates that I.M. Healthy brand SoyNut Butter is a likely source of this outbreak. Sixteen people infected with the outbreak strain of STEC O157:H7 have been reported from nine states. A list of the states and the number of cases in each can be found on the Case Count Map page.SoyNut Butter is a nut-free substitute for peanut butter.
