DANVILLE, CA - February 1st, 2026 - Contra Costa County health officials are sounding the alarm over a significant surge in measles cases, reaching a 33-year high and prompting concerns about a potential nationwide resurgence of the highly contagious viral illness. The recent increase is not isolated to Contra Costa, mirroring patterns observed in several other states and sparking debate amongst public health experts about vaccination rates and the potential erosion of herd immunity.

As of yesterday, Contra Costa County confirmed multiple cases of measles, triggering an urgent public health response. Dr. Louise Bravo, Contra Costa Health Services' health officer, emphasized the severity of the situation. "Measles is incredibly contagious - far more so than influenza or even COVID-19 - and can be devastating, particularly for infants, young children, pregnant women, and individuals with compromised immune systems," Dr. Bravo stated. "Vaccination remains the single most effective tool in preventing the spread of this disease and protecting our community."

This surge marks a concerning reversal of progress made in measles elimination. The last substantial measles outbreak in Contra Costa County occurred in 1994, a period before the widespread implementation of robust vaccination programs. The current situation demands immediate attention and a renewed focus on preventative measures.

Understanding the Measles Threat

Measles, caused by the morbillivirus, is characterized by a distinct and uncomfortable rash, but the illness goes far beyond skin deep. It's an airborne disease, meaning it spreads easily through respiratory droplets produced by coughing or sneezing. An infected person can transmit the virus to others even before symptoms appear. The incubation period is typically 10-14 days, making it difficult to trace the source of infection.

The symptoms, initially resembling a common cold - fever, cough, runny nose, and conjunctivitis (red, watery eyes) - are followed by the characteristic maculopapular rash that begins on the face and spreads throughout the body. However, measles can lead to serious complications, including pneumonia (the most common complication), encephalitis (inflammation of the brain, potentially causing permanent neurological damage), acute otitis media (ear infection), and, in rare but tragic cases, death.

The Role of Vaccination and Declining Rates

The measles, mumps, and rubella (MMR) vaccine is highly effective, providing approximately 97% protection after two doses. 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 a second dose between 4 and 6 years of age. However, vaccination rates have been steadily declining in recent years, fueled by misinformation, vaccine hesitancy, and access barriers.

Public health officials are pointing to several factors contributing to the decline. The COVID-19 pandemic disrupted routine pediatric care, leading to delayed vaccinations for some children. Furthermore, the spread of inaccurate information online regarding vaccine safety has eroded public trust. A growing anti-vaccination movement continues to challenge the scientific consensus on the benefits of immunization.

Contra Costa County's Response and Nationwide Implications

Contra Costa Health Services is actively working to contain the outbreak through vaccination clinics, contact tracing, and public education campaigns. The county's website ([ https://www.cchealth.org/ ]) provides detailed information about measles, vaccination schedules, and clinic locations. They are urging residents to review their vaccination records and ensure they are up-to-date.

The situation in Contra Costa County serves as a stark reminder of the importance of maintaining high vaccination rates to protect the community. If current trends continue, the U.S. could see a widespread resurgence of measles, reversing decades of progress towards elimination. Several infectious disease experts are now suggesting that the U.S. may no longer be considered measles-free, a status it achieved in 2000.

What You Can Do:

• Check Your Vaccination Status: Ensure you and your family are fully vaccinated against measles.
• Stay Home If Sick: If you experience symptoms of measles, isolate yourself immediately and contact your healthcare provider.
• Practice Good Hygiene: Frequent handwashing and covering your mouth and nose when coughing or sneezing can help prevent the spread of respiratory illnesses.
• Share Accurate Information: Combat misinformation about vaccines by sharing credible sources of information from the CDC and other reputable organizations.

This is a developing story, and we will continue to provide updates as more information becomes available. The current outbreak underscores the need for vigilance and a collective commitment to protecting public health through vaccination.
