Zika Virus: Answers to Your Questions from Experts

As the Zika virus gains attention in the media, it’s natural to feel anxious. However, seeking the truth can help ease those worries. Below are some of the key questions that were discussed during our session, along with the expert responses.

Is the virus a concern for infants?

Primarily, the focus is on pregnant women and their developing babies. There’s no evidence suggesting that infants experience a different infection course.

Does the body naturally clear the Zika virus?

The virus typically leaves the bloodstream within about a week. While symptoms can last from a few days up to a week, we are still investigating the potential for long-term infections.

After one exposure, does immunity develop? Are future pregnancies at risk?

Once infected, individuals are likely immune to future Zika infections, and there is no current evidence indicating that Zika increases birth defect risks in subsequent pregnancies.

Are newly pregnant women at higher risk?

The early stages of pregnancy are critical for fetal development, but we still lack complete data on risks associated with later pregnancy stages.

Is it safe for pregnant women to travel domestically?

Yes, there is currently NO evidence of Zika transmission in the continental U.S. Moreover, being around international travelers does not increase your risk.

How does Zika affect individuals with compromised immune systems?

Most people (about 4 out of 5) with Zika show no symptoms, while others might experience mild symptoms. Pregnant women, however, may face risks to their developing fetus.

Can Zika be transmitted through breast milk?

So far, there are no reports of Zika being transmitted through breastfeeding. The benefits of breastfeeding are significant, and mothers are encouraged to continue even in Zika-affected areas.

Is a vaccine still years away?

The development of a Zika vaccine is being expedited. Recent discussions between the U.S. and Brazilian officials focus on accelerating vaccine research.

Is Zika similar to viruses like mononucleosis, remaining in the body for long periods?

Currently, there’s no evidence to support this notion.

Should I use mosquito repellent if I have allergies to bites?

Yes, it’s crucial to protect yourself from mosquitoes, especially in Zika-affected areas.

As for those who traveled to Zika-prone areas, those who are pregnant should consider testing, as recommended. The virus generally clears within a week, and future pregnancies are thought to be safe after clearing the infection.

What are the implications for newborns or young children?

Most Zika cases are mild, and once infected, individuals are likely protected from future infections. However, ongoing research is essential.

Will Zika-carrying mosquitoes reach Northern California?

Currently, we do not expect Zika-infected mosquitoes to establish a presence in Northern California. However, the species that can transmit Zika is present in the southern U.S.

Should pregnant women traveling to Florida be concerned?

Traveling to Florida is generally considered safe, and we currently have no restrictions against traveling there.

For those who are newly pregnant or planning to conceive, it’s advised to take normal precautions against mosquitoes, especially with spring and summer approaching. The CDC has not reported evidence of Zika transmission in the continental U.S., and not every mosquito poses a risk.

In conclusion, there are measures we can take to help those in countries facing higher risks from the Zika virus. The U.S. government is collaborating internationally to address this challenge. For further reading, explore this link for additional insights.
