CDPH reported six recent measles cases in Placer and Sacramento counties on March 5. Caregivers across California can use the alert to verify vaccine records now and know exactly who to contact if an exposure notice arrives.
On March 5, 2026, the California Department of Public Health reported six recent measles cases in Placer and Sacramento counties and said public-health officials were investigating additional suspected cases. CDPH identified the group as California’s third measles outbreak of 2026.
The most useful statewide response is not to assume that every California community has a local outbreak. It is to make vaccine records easy to find, recognize who may need faster medical guidance after an exposure, and know how to contact a healthcare provider before showing up at a clinic with possible measles symptoms.
Quick Answer
CDPH’s March 5 alert concerned a Sacramento-region outbreak involving six recent cases in Placer and Sacramento counties. Caregivers should check each family member’s measles vaccination record now rather than trying to reconstruct it after an exposure notice. The California Digital Vaccine Record can show vaccinations reported to the state registry, but CDPH notes that some doses may be missing. If someone is not fully immunized or is unsure of immunity, contact a healthcare provider. If an exposure notice arrives, follow it promptly because post-exposure decisions can be time-sensitive. Infants, pregnant people without immunity and people with weakened immune systems need especially prompt medical guidance. If measles is suspected, call the healthcare provider before visiting a healthcare facility unless emergency care is needed.
What California Reported on March 5, 2026
CDPH reported six recent measles cases in Placer and Sacramento counties. The agency said public-health officials were investigating additional suspected cases across multiple jurisdictions and notifying people who may have been exposed.
The outbreak began with an unvaccinated toddler in Sacramento County who had recently traveled to an area of South Carolina with an ongoing measles outbreak. Placer County later identified three siblings from another household who had direct contact with that child.
- Four linked early cases
- The initial Sacramento County case and three Placer County siblings were connected by direct contact.
- Fifth case reported March 4
- A child from the same community had attended an educational enrichment program while infectious.
- Sixth case reported March 5
- Placer County reported another unvaccinated child from a different household in the same community.
CDPH said as many as 130 children may have been exposed at the educational enrichment program and that the program temporarily closed while public-health officials worked on exposure notifications.
Keep the Sacramento-Region Outbreak in Geographic Perspective
The March 5 release described an outbreak centered in Placer and Sacramento counties. It did not say every California county had local measles transmission.
The statewide message was still important because measles was spreading elsewhere in the United States and internationally. Travel can introduce cases into communities where many people have not recently thought about measles.
Local Outbreak, Statewide Preparation
The Sacramento-region cases are a reason for Californians to verify immunization records and follow official exposure guidance—not a reason to assume a local exposure occurred without a notice or other specific information.
Do not leave medicines on a kitchen counter or at a sick child’s bedside simply because another dose may be needed later. Return them to the secure storage location after each use.
Build One Vaccine Record for Each Child and Adult in the Household
CDPH directs Californians who are unsure of measles vaccination status to check the California Digital Vaccine Record or ask a healthcare provider. The Digital Vaccine Record is drawn from the California Immunization Registry and can include vaccinations reported by healthcare providers and pharmacies.
CDPH also warns that the digital record may not contain every vaccine dose. Missing information should therefore trigger a record search, not an assumption that a vaccine was never received.
- Request the California Digital Vaccine Record.
Use the state portal to look for documented immunizations for each family member.
- Check the healthcare provider’s records.
Contact pediatric, primary-care or other clinics where vaccines may have been administered.
- Review school or childcare records.
Schools may have older immunization documentation that helps fill gaps in a child’s history.
- Keep paper records if you have them.
Older vaccine cards, baby books and prior clinic printouts can be useful when digital records are incomplete.
- Do not invent missing dates.
If records conflict or a dose cannot be verified, contact the healthcare provider for guidance.
Who Should Pay Closer Attention to a Measles Exposure Alert
CDPH says unvaccinated people are at high risk after measles exposure. Families should respond promptly when they receive a direct exposure notification, cannot confirm immunity, or have recently traveled to an area with measles activity.
Some people need especially prompt clinical guidance after a possible exposure because post-exposure options and timing can differ by age, pregnancy status and immune-system status.
- Infants under 12 months
- CDPH specifically identifies infants as a group for whom immune globulin may be considered after exposure.
- Pregnant people without immunity
- Do not use a general vaccine checklist to make a post-exposure decision; contact the healthcare provider promptly.
- People with weakened immune systems
- Exposure management can require individualized medical guidance and should not be delayed.
This article does not determine whether any individual needs MMR vaccine or immune globulin after an exposure. Those decisions require timely evaluation by the appropriate healthcare provider or public-health authority.
If Your Family Receives a Measles Exposure Notice
Treat the notice as a time-sensitive public-health message. CDPH’s March 5 guidance says people who are not fully immunized or are unsure of immunity should contact a healthcare provider about MMR vaccination.
CDPH also says that when exposure occurred less than seven days ago, the healthcare provider should be contacted about vaccination or immune globulin for prevention. The exact recommendation depends on the person and the timing, so do not choose or delay a post-exposure option based only on a general article.
- What date, time and location does the exposure notice identify?
- Can we document the person’s measles vaccination history?
- Is the person an infant, pregnant without documented immunity, or immunocompromised?
- Which healthcare provider or local public-health number does the notice tell us to contact?
- Does the notice instruct the person to stay home or limit contact with others?
- What symptoms and monitoring dates are listed in the public-health instructions?
Ask the Pharmacy About Service Availability—Not Exposure Treatment Decisions
Las Palmas Pharmacy can answer questions about whether a vaccine service is offered and what records to bring. Exposure-specific MMR or immune-globulin decisions belong with a healthcare provider or public-health authority.
If Measles Symptoms Are Suspected, Call Before Visiting a Healthcare Facility
CDPH says measles can begin with fever and may include cough, runny nose, red or watery eyes and a rash. Those symptoms can also occur with other illnesses, so a symptom list cannot diagnose measles.
If measles is suspected because of symptoms and a possible exposure or travel history, CDPH advises calling the healthcare provider before going to a healthcare facility. Calling first gives the facility a chance to provide instructions that reduce exposure to other patients.
Do Not Walk Into a Waiting Room Without Calling First
\When measles is suspected, contact the healthcare provider for instructions before arrival unless emergency care is required. Call 911 for a medical emergency.
Know What a Pharmacy Can—and Cannot—Help With
A pharmacy can help with practical vaccine-service questions such as whether MMR vaccine is offered, whether an appointment is needed, what age groups the pharmacy serves, what records to bring and whether insurance can be processed.
A pharmacy should not replace the healthcare provider or public-health department for a suspected exposure, a possible measles diagnosis, or a decision about post-exposure vaccination or immune globulin.
- Pharmacy
- Routine vaccine availability, appointment logistics, pharmacy records and insurance-processing questions.
- Healthcare provider
- Immunity questions, symptoms, exposure management, pregnancy or immune-system concerns and clinical decisions.
- Public health
- Exposure notifications, outbreak instructions, isolation guidance and community-specific measles information.
Six Questions Caregivers Can Ask Before a Measles Question Becomes Urgent
- Where is the most complete vaccine record for each family member?
- Does the Digital Vaccine Record appear complete, or are known doses missing?
- Which healthcare provider should we call if immunity cannot be confirmed?
- Do we have the phone number for our county public-health department saved?
- If we are traveling, should vaccine timing be reviewed before departure?
- Does our pharmacy offer routine MMR vaccination for the relevant age group?
Frequently Asked Questions
Was there a measles outbreak across all of California in March 2026?
No. CDPH’s March 5 announcement described six recent cases in Placer and Sacramento counties and called the cluster California’s third measles outbreak of 2026. The statewide advice was to verify vaccination status and follow official exposure guidance.
Where can I find my family’s California vaccine records?
Start with the California Digital Vaccine Record portal. You can also contact the healthcare provider or clinic where vaccines were given, review school or childcare records for children, and look for older paper immunization records.
What if the Digital Vaccine Record is missing a dose I know was given?
CDPH says not every vaccination may appear in the state record. Contact the healthcare provider that administered the dose and ask about updating the California Immunization Registry rather than assuming the dose never occurred.
What should I do if I receive a measles exposure notice?
Follow the notice promptly and contact the healthcare provider or local public-health authority. Post-exposure decisions can depend on the timing of exposure, vaccine history, age, pregnancy and immune-system status.
Should I walk into a clinic if I think my child has measles?
CDPH advises calling the medical provider before visiting a healthcare facility when measles is suspected so the facility can give instructions designed to reduce exposure to others. Call 911 for a medical emergency.
Can a pharmacy answer questions after a measles exposure?
A pharmacy can answer routine questions about vaccine-service availability and pharmacy records, but exposure-specific vaccination, immune-globulin, testing or treatment decisions should be handled by a healthcare provider or public-health authority.
Check the Records Before You Need Them
The Sacramento-region outbreak is a reminder that vaccine records are most useful when they are complete and easy to find before travel, a school notice or a possible exposure. Keep one verified record for each family member and save the right healthcare and public-health contacts.
