Egg Donation From Donors In A Zika Area

Updated June 2026

Quick Answer: In 2026, Zika is a substantially lower risk for egg donation than it was during the 2015 to 2017 outbreak. CDC surveillance shows minimal active Zika transmission in the Americas, and standardized donor testing protocols make it safe to use donors with prior Zika exposure in most cases. There has never been a documented case of Zika transmission through egg donation in the United States.

Key Takeaways

• The last locally acquired Zika case in the continental U.S. was documented in 2017.
• The Pan American Health Organization (PAHO) classifies most countries in the Americas as having sporadic or no current Zika transmission.
• ASRM and FDA guidance now recommend risk-based, not blanket, screening for donors with recent exposure to areas of active transmission.
• Donors who have traveled to active Zika areas are typically eligible after appropriate testing and, in some cases, a three-month waiting period.
• There has never been a documented case of Zika transmission via egg donation in the United States.

For several years, intended parents were told to avoid egg donors who lived in or had recently traveled to a Zika-affected area. Most agencies, including ours, included questions about Zika exposure in FDA-approved health questionnaires. That guidance came from a real and serious public health concern.

The picture has changed significantly. Zika has not disappeared, but the active risk in 2026 looks very different from what it did in 2019. This post offers an updated look at what intended parents should know about Zika and egg donation today.

A Quick Refresher on Zika

Zika is a virus transmitted primarily through the bite of an infected Aedes mosquito, though it can also be spread sexually. In most adults, Zika causes only mild symptoms or none at all. The serious concern is during pregnancy: Zika infection in a pregnant woman can cause congenital Zika syndrome in the developing fetus, including microcephaly and other brain development issues.

This is why Zika has always been treated with particular seriousness in fertility medicine. Anything that could potentially affect a pregnancy or a developing baby gets careful attention.

The Current State of Zika Risk

According to the most recent CDC surveillance data, locally acquired Zika cases in the continental United States have remained at or near zero for several years. The last large outbreak in the continental U.S. occurred in 2016 in Florida and Texas, and the last documented local transmission case was in 2017.

Globally, Zika transmission has dropped substantially compared to the 2015 to 2017 peak. The Pan American Health Organization classifies most countries in the Americas as having sporadic or no current Zika transmission, with continued monitoring in a small number of regions. Africa, Southeast Asia, and parts of the Pacific still report cases, but the level is far below historical highs.

This shift opens more options for intended parents. Donors and surrogates who were previously excluded based on residence or travel history are now, in many cases, eligible after appropriate testing.

What Current Guidance Looks Like

The American Society for Reproductive Medicine (ASRM) and the FDA continue to recommend Zika screening for donors with recent exposure to areas where Zika is actively circulating. The keyword is “actively.” The guidance is no longer a blanket exclusion of donors from entire continents. It is now risk-based and current, with the CDC’s interactive map serving as the reference point for active transmission.

In practice, this means:

• Most U.S. donors and donors from countries with no current Zika activity do not require special testing or waivers.
• Donors who have recently traveled to areas with active transmission can usually proceed after appropriate testing and, in some cases, a brief waiting period (typically 3 months).
• Clinics still use a Zika-specific informed consent form for cases that involve any current or recent exposure to active areas, ensuring intended parents understand the risk profile.

Zika Testing for Donors

If your chosen donor has any current or recent exposure to an active Zika area, your reproductive endocrinologist will arrange appropriate testing. This typically includes a blood test for Zika antibodies and, in some cases, urine testing. Results give your medical team the information they need to clear your donor or recommend an alternative path.

A key point that has not changed: there has never been a documented case of Zika transmission through egg donation in the United States. The combination of testing, waiting periods, and risk-based screening has been highly effective.

What This Means for Intended Parents

The bottom line: the Zika risk for egg donation in 2026 is meaningfully lower than it was when this post was originally written. The CDC’s current data, expanded testing options, and the natural decline in global Zika transmission have together opened more donor options for intended parents.

If you are considering a donor who has traveled to or lives in an area with any Zika history, your fertility team will guide you through the current testing requirements. The decision rests on the most recent CDC data, not on outdated maps from years ago.

Frequently Asked Questions

Is Zika still a risk for egg donation in 2026? 

The risk is significantly lower than it was during the 2016 to 2017 outbreak. CDC surveillance shows minimal active Zika transmission globally, and standardized testing protocols make it possible to safely use donors with prior Zika exposure in most cases.

Where can I check current Zika activity? 

The CDC maintains an up-to-date Zika travel information page at cdc.gov/zika. This is the authoritative source your clinic will reference.

Has there ever been a case of Zika transmitted through egg donation? 

No. There has never been a documented case of Zika transmission through egg donation in the United States, thanks to consistent testing and screening practices.

Are donors from South America still excluded? 

No. Blanket exclusions based on continent are no longer the current practice. Donor eligibility is determined by recent travel and current CDC data, with testing available for any donor who has been in an area with active transmission.
