Health officials are once again alerting the public about possible hepatitis A exposure – this time at that Austin Texas Whataburger in Central Austin. A restaurant employee there at the 2800 Guadalupe St. location has been diagnosed with the hepatitis A virus.  The same officials urge patrons to seek medical advice and treatment.

Hardly a month passes without a warning from a health department somewhere that an infected food handler is the source of yet another potential hepatitis A outbreak. Absent vaccinations of food handlers, combined with an effective and rigorous hand-washing policy, there will continue to be more hepatitis A outbreaks. It is time for health departments across the country to require vaccinations of food-service workers, especially those who serve the very young and the elderly.

Hepatitis A is a communicable disease that spreads from person-to-person. It is spread almost exclusively through fecal-oral contact, generally from person-to-person, or via contaminated food or water. Hepatitis A is the only foodborne illness that is vaccine-preventable. According to the U.S. Centers for Disease Control and Prevention (CDC), since the inception of the vaccine, rates of infection have declined 92 percent.

CDC estimate that 83,000 cases of hepatitis A occur in the United States every year, and that many of these cases are related to food-borne transmission. In 1999, more than 10,000 people were hospitalized due to hepatitis A infections, and 83 people died. In 2003, 650 people became sickened, four died, and nearly 10,000 people got IG (immunoglobulin) shots after eating at a Pennsylvania restaurant. Not only do customers get sick, but also businesses lose customers or some simply go out of business.

Although CDC has not yet called for mandatory vaccination of food-service workers, it has repeatedly pointed out that the consumption of worker-contaminated food is a major cause of foodborne illness in the U.S.

Hepatitis A continues to be one of the most frequently reported, vaccine-preventable diseases in the U.S., despite FDA approval of hepatitis A vaccine in 1995. Widespread vaccination of appropriate susceptible populations would substantially lower disease incidence and potentially eliminate indigenous transmission of hepatitis A infections. Vaccinations cost about $50. The major economic reason that these preventive shots have not been used is because of the high turnover rate of food-service employees. Eating out becomes a whole lot less of a gamble if all food-service workers faced the same requirement.

According to CDC, the costs associated with hepatitis A are substantial. Between 11 percent and 22 percent of persons who have hepatitis A are hospitalized. Adults who become ill lose an average of 27 days of work. Health departments incur substantial costs in providing post-exposure prophylaxis to an average of 11 contacts per case. Average costs (direct and indirect) of hepatitis A range from $1,817 to $2,459 per case for adults and from $433 to $1,492 per case for children younger than 18. In 1989, the estimated annual direct and indirect costs of hepatitis A in the U.S. were more than $200 million, equivalent to more than $300 million in 1997 dollars.  A new CDC report shows that, in 2010, slightly more than 10 percent of people between the ages of 19 and 49 got a hepatitis A shot.

Vaccinating an employee make sense.  It is moral to protect customers from an illness that can cause serious illness and death. Vaccines also protect the business from the multi-million-dollar fallout that can come if people become ill or if thousands are forced to stand in line to be vaccinated to prevent a more serious problem.
