Health Department reminds community of importance of vaccines
Thirty years ago, a Hepatitis A outbreak in Hamilton County sent more than 1,000 residents seeking treatment. Today, that anniversary serves as a powerful reminder: outbreaks can happen at any time, and vaccination is our best defense.
In January 1996, potential exposure linked to a Westfield restaurant led more than 1,000 people to receive immunoglobulin shots, with eight confirmed cases reported. Health Department staff worked extended hours to contain the spread, inform the public, and protect the community.
Hepatitis A is a highly contagious liver infection caused by the Hepatitis A virus. It spreads through close personal contact or by consuming contaminated food or drink. Symptoms can include fever, fatigue, nausea, abdominal pain, dark urine, and jaundice. Vaccination is the best way to prevent infection.
The 1996 outbreak remains a powerful reminder of how quickly infectious diseases can spread – and how critical prevention efforts are in protecting public health.

“Thirty years ago, our community saw firsthand how rapidly an infectious disease can impact thousands of people,” Health Department Administrator Jason LeMaster said. “That experience reinforces why we must remain vigilant against vaccine-preventable diseases. Vaccines are one of the safest and most effective tools we have to protect individuals, families, and our community.”
Today, public health officials are closely monitoring measles outbreaks occurring in parts of the United States and around the world. Measles is one of the most contagious viruses known and can lead to serious complications, especially in young children and those with weakened immune systems. Like Hepatitis A, measles is preventable through routine vaccination.

VanMetre
“The circumstances we saw in 1996 could absolutely happen again with a disease like measles if vaccination rates drop,” Health Department Director of Nursing Janice VanMetre said. “Measles spreads incredibly fast – even faster than Hepatitis A – and it only takes one case to spark an outbreak in an under-vaccinated community. We strongly encourage residents to make sure they and their children are up to date on Hepatitis A, MMR, and all recommended vaccines.”
The Hamilton County Health Department encourages residents to review their immunization records, consult with their healthcare provider, and seek reliable information from trusted public health professionals.
