Iowa Reports First Measles Case Since 2019: Symptoms, Causes, and How to Stay Safe

Iowa health officials have confirmed the state’s first case of measles since 2019, raising new public health concerns amid a global increase in vaccine-preventable diseases. The patient is a child from Western Iowa who was reportedly unvaccinated and had recently traveled internationally, according to the Iowa Department of Health and Human Services (HHS).

This development comes as measles cases are once again on the rise in several parts of the United States and around the world, largely due to declining vaccination rates and increased global travel. Health authorities are urging residents, especially parents, to be aware of the symptoms and take preventive measures seriously.

What Is Measles?

Measles is a highly contagious viral infection caused by the rubeola virus. It spreads easily through airborne droplets from coughing or sneezing, and can also linger in the air and on surfaces for up to two hours after an infected person leaves the area.

According to the Centers for Disease Control and Prevention (CDC), measles can infect up to 90% of non-immune individuals who are exposed to the virus.

Why This Case Matters

The last confirmed measles case in Iowa was reported in 2019. Since then, the state had remained measles-free — until now.

“This case is a reminder that measles is not just a disease of the past. It remains a real threat, especially to unvaccinated individuals,” said Dr. Robert Kruse, Iowa’s State Medical Director and Epidemiologist.

Health officials have begun contact tracing to identify anyone who may have come into contact with the infected child. So far, no additional cases have been reported.

Measles Symptoms: What to Watch For

Recognizing measles symptoms early can make a major difference in preventing further spread. Symptoms usually appear 7 to 14 days after exposure to the virus and progress in stages.

Here are the most common symptoms:

1. High Fever

The first sign is often a high fever, which can spike to 104°F (40°C) or higher. This usually starts before any rash appears.

2. Cough, Runny Nose, and Red Eyes

The fever is usually accompanied by:

• Persistent dry cough
• Nasal congestion and runny nose
• Red, watery eyes (conjunctivitis)

3. Koplik Spots

Small white spots inside the mouth, known as Koplik spots, may appear a day or two before the body rash. These are considered a telltale sign of measles but can be missed.

4. Rash

A red, blotchy rash typically begins 3 to 5 days after symptoms start, often on the face and behind the ears, before spreading downward to the trunk, arms, and legs. The rash usually lasts about a week.

When to Seek Medical Attention

If you or your child experiences a combination of high fever, rash, and cold-like symptoms — especially after recent travel or exposure to others with similar symptoms — contact a healthcare provider immediately.

Do not go directly to the clinic or emergency room without notifying staff in advance, as measles is extremely contagious.

How to Protect Yourself and Others

The best protection against measles is vaccination. The MMR vaccine (Measles, Mumps, Rubella) is highly effective and has been safely used for decades.

Who Should Get Vaccinated?

• Children should receive two doses: the first at 12–15 months, and the second at 4–6 years.
• Adults born after 1957 should ensure they’ve received at least one dose, unless they have lab-confirmed immunity.
• Travelers going abroad should verify their vaccination status.

According to the CDC, two doses of the MMR vaccine are about 97% effective at preventing measles.

Global Trends and Local Risks

This case in Iowa is part of a concerning trend. The World Health Organization (WHO) recently warned that measles cases globally surged by 18% in 2024, largely due to interruptions in routine vaccinations during the COVID-19 pandemic.

In the U.S., several states have also reported new measles infections in early 2025, many linked to international travel and low community vaccination coverage.

What Officials Are Saying

“We strongly urge all Iowans to check their vaccination records and ensure they and their families are fully protected,” said Dr. Kruse. “This virus doesn’t need much to spread — a single case can quickly become an outbreak if immunity is low.”

Final Thoughts

Measles may seem like a disease of the past, but this new case in Iowa proves that it’s very much a present concern — especially in areas with low vaccination rates or hesitancy toward immunization.

Staying informed, recognizing early symptoms, and ensuring timely vaccinations are key to keeping your family and community safe.
