Riverside County, CA - February 15th, 2026 - Riverside County Public Health officials are reporting a significant increase in measles cases, triggering a public health alert and a renewed push for widespread vaccination. This isn't simply a localized spike; it's a concerning trend mirroring similar upticks across the nation and globally, raising questions about vaccination rates, travel patterns, and the resilience of public health infrastructure.

The current outbreak, confirmed within the last several weeks, is primarily linked to recent international travel and a concerning segment of the population remaining unvaccinated. While initial cases were isolated, the rate of transmission has increased, prompting officials to classify it as an outbreak, demanding swift and coordinated action.

Measles: A Highly Contagious Threat

Measles, a highly contagious viral disease, was declared eliminated in the United States in 2000. However, imported cases - often brought in by travelers returning from countries where measles is still prevalent - can spark outbreaks, particularly in communities with low vaccination coverage. The virus spreads through the air when an infected person coughs or sneezes. It's so contagious that if one person has measles, 90% of those who are not immune will catch the disease.

The symptoms, typically appearing 10-14 days after exposure, begin with fever, cough, runny nose, and conjunctivitis (red, watery eyes). What distinguishes measles is the characteristic rash, which starts on the face and spreads to the rest of the body. While seemingly straightforward, measles can lead to serious complications, including pneumonia, encephalitis (inflammation of the brain), and even death. Young children, individuals with compromised immune systems, and pregnant women are at the highest risk.

The Importance of the MMR Vaccine

"Vaccination remains the single most effective defense against measles," emphasizes Dr. Emily Carter, Riverside County Public Health Officer. "The MMR (Measles, Mumps, and Rubella) vaccine is incredibly safe and highly effective, providing approximately 97% protection after two doses." Dr. Carter highlights that the current outbreak serves as a stark reminder of the critical role vaccination plays in protecting not only individuals but also the broader community, achieving herd immunity.

The Centers for Disease Control and Prevention (CDC) recommends that children receive their first dose of the MMR vaccine between 12 and 15 months of age, and the second dose between 4 and 6 years old. Adults born in 1957 or later who haven't had measles or been vaccinated should also receive two doses of the MMR vaccine. Those planning international travel, especially to regions with ongoing measles outbreaks, are strongly advised to ensure they are fully vaccinated.

County Response and Outreach Efforts

Riverside County Public Health is working diligently with healthcare providers, hospitals, and schools to investigate cases, trace contacts, and implement control measures. This includes identifying and isolating infected individuals to prevent further spread. A crucial component of the response is targeted outreach to vulnerable communities, addressing vaccine hesitancy and ensuring access to vaccination services.

"We're focusing on areas with lower vaccination rates, providing education in multiple languages, and hosting vaccination clinics in convenient locations," explains Maria Rodriguez, a community health worker involved in the county's outreach program. "Misinformation about vaccines is a significant challenge, so we're emphasizing the scientific consensus and the proven safety and efficacy of the MMR vaccine."

National and Global Context

The rise in measles cases isn't unique to Riverside County. Several states across the U.S. are experiencing similar outbreaks, mirroring a global resurgence of the disease. Factors contributing to this trend include declining vaccination rates in some areas, disruptions to immunization programs due to the COVID-19 pandemic, and increased international travel. The World Health Organization (WHO) has warned that measles cases are rising globally, putting millions of children at risk.

How to Protect Yourself and Your Community

Residents of Riverside County are urged to:

• Check your vaccination status: If you are unsure whether you have been vaccinated against measles, contact your healthcare provider or check your vaccination records.
• Get vaccinated: If you are not vaccinated or are unsure of your status, schedule an appointment to receive the MMR vaccine.
• Stay home if you are sick: If you experience symptoms of measles, isolate yourself immediately and contact your healthcare provider.
• Report suspected cases: Healthcare providers are required to report all suspected cases of measles to the county health department.

Information on vaccination locations, schedules, and resources is readily available on the Riverside County Public Health website ([ https://www.rivco.org/publichealth ]). The health of the community depends on collective action, and vaccination remains the cornerstone of measles prevention.
