Measles marches on; 712 confirmed measles cases reported in 24 states, including two new states since last week
In its April 10 weekly update, CDC reported 712 confirmed measles cases in 2025, with 93% of the cases associated with seven outbreaks. Indiana and Arkansas both reported cases since the last weekly update. Most reported cases (541 of 712, 76%) were reported by the Texas Department of State Health Services. To date, three people have died, including the confirmed measles deaths of two otherwise healthy unvaccinated children in Texas, age 6 and 8 years, and one unvaccinated adult in New Mexico who was infected with measles but did not seek medical attention before dying. The adult’s cause of death is under investigation.
A map of 2025 measles cases, as of April 10, is shown below.

On April 8, CDC issued updated measles guidance to healthcare providers, urging them to stay alert for measles cases. The CDC notice reminds healthcare professionals of four basic steps to take when a measles case is suspected:
- Isolate your patient with suspected measles immediately
- Immediately notify public health
- Collect samples
- Manage patients with supportive care, being careful to avoid overuse of vitamin A, which can cause toxicity or birth defects if given during pregnancy
For the details of each step, see the April 8 CDC web page: Healthcare Providers: Stay Alert for Measles Cases.

National Infant Immunization Week is April 21–28; jump start promotion activities with Vaccinate Your Family’s NIIW resources
National Infant Immunization Week (NIIW), April 21–28, highlights the importance of protecting infants from vaccine-preventable diseases and celebrates the achievements of immunization partners. Since 1994, hundreds of communities have joined together during NIIW to highlight the crucial role vaccination plays in protecting our children, communities, and public health.
CDC, the American Academy of Pediatrics, and the American Academy of Family Physicians recommend that children stay on track with their well-child appointments and routine vaccinations. Completing the recommended vaccinations by age 2 years is the best way to protect young children from 15 potentially life-threatening diseases. In light of the recent measles outbreaks, these messages are more important than ever.
Relevant resources are available from Vaccinate Your Family (VYF). VYF’s #VaxToTheFuture campaign is a bilingual initiative to remind parents, caregivers, and communities of a simple but powerful truth: a childhood free from vaccine-preventable diseases is possible — but only if we remember the lessons of the past and choose to vaccinate.

CDC resources cited in last week’s edition of IZ Express are no longer posted online. CDC continues to offer NIIW logos in various languages and formats.

Our last weekly influenza season update as influenza lingers; 188 children have died so far
As the prevalence of influenza-like illness finally dips below the epidemic threshold, this article will be the final routine IZ Express weekly influenza season update, barring a late-season influenza resurgence. For week 14, ending April 5, CDC’s Weekly Influenza Surveillance Report, FluView, reports that five jurisdictions showed influenza-like illness activity at moderate levels. CDC classified the 2024–25 season as a high-severity season for people of all ages, with the highest hospitalization rate recorded since the 2010–11 season. During week 14, 2.5% of outpatient visits involved influenza-like illness, which is below the epidemic threshold of 3.0% after 18 weeks of sustained activity above the epidemic threshold. Twenty pediatric deaths associated with seasonal influenza virus infection were reported during week 14, bringing the 2024–25 season total to 188 childhood deaths so far.

CDC and medical societies recommend that children age 6 months through 8 years receive two doses of influenza vaccine during the first season they are vaccinated against influenza to help them mount an effective immune response to a single influenza vaccination in future seasons. Continue offering influenza vaccination to children who need two doses but have had only one so far this season.

Recap: Immunize.org posts Spanish translations of 17 recently updated VISs
Immunize.org updated Spanish translations of 17 VISs to correspond with CDC's recently posted revisions, dated January 31, 2025. The revisions comply with a January 20, 2025, presidential executive order. Changes were limited to replacing the words “persons,” “person,” and “they” with the words "women," "woman," and "she" when referring to pregnancy or breastfeeding.
When given any VIS translation, the patient should also receive the current VIS in English. You Must Provide Patients with Vaccine Information Statements (VISs) – It’s Federal Law! offers additional tips on using VISs.
To locate all available VISs and clinical resources in a given language, visit our translations home page.
Check the version dates of your inventory of VIS translations at regular intervals. Discard translations of previous versions as updated translations of current versions become available. Due to the minimal content changes, Immunize.org is not updating other VIS translations at this time.

Updated 65+ Flu Defense website offers resources for healthcare professionals serving older adults
Confident healthcare provider recommendations for influenza vaccine are powerfully persuasive. This influenza season has been a tough one. To help you maximize patient protection, Immunize.org, in collaboration with CSL Seqirus, updated the 65+ Flu Defense website.

This helpful site includes information, tools, and tips for communicating with adults age 65 and older about the scope and severity of influenza. Resources include:
Older adults are at increased risk of severe influenza, COVID-19, and RSV illness, including hospitalization and death, especially if they are not up to date on these vaccinations. A clinician recommendation is the most important reason why a patient will get vaccinated.
Check out the updated 65+ Flu Defense website to assist your ongoing efforts in protecting this vulnerable population.

"Strategies for Communicating with Parents About Vaccines" published in JAMA
In the April 9 issue, JAMA published Strategies for Communicating with Parents About Vaccines. The article’s table, "Strategies for Discussions of Vaccination with Patients," appears below. The article contains additional detail about each of these communication approaches.
Strategy |
Example |
Shared goals |
"You and I have a shared goal of trying to do what is best for your child." |
Presumptive approach |
"Johnny is due for three vaccines today." |
Social norms |
"Almost all of my patients have gotten this vaccine." |
Permission to share |
"This question has come up for me a few times, so I looked into it. Would it be okay if I go over what I found out for you?" |
Prebunking |
"You should be careful about what you see on the internet about vaccines because there is a lot of inaccurate information. I can recommend some sources that I trust if you have questions." |
Values-based messaging |
"One way of thinking about making the decision to vaccinate your child is that, similar to encouraging them to be active and eat healthy foods, it is a decision to help them thrive and grow into a healthy adult." |
"Approaches for MMR Vaccination During a Measles Outbreak and Evolving Domestic Attitudes" published in JAMA
In the April 9 issue, JAMA published Approaches for MMR Vaccination During a Measles Outbreak and Evolving Domestic Attitudes by Kathryn M. Edwards, MD. A portion of the commentary appears below.
When CDC guidance is slow or incomplete, infectious disease specialists should provide updated educational materials to inform clinicians about the signs and symptoms of measles and appropriate infection control measures for office and clinic settings. Specialty organizations such as the American Academy of Pediatrics, the American Academy of Family Practitioners, the Infectious Diseases Society of America, and other professional societies must step forward to strongly support vaccination and provide medical guidance. Efforts should also be extended to support our CDC colleagues who have toiled for decades in the interest of public health to ensure their expertise is heard.
