The Spokane Regional Health District is trying to work with restaurants to avoid declaring a hepatitis A emergency that could cost businesses thousands of dollars.
Restaurant representatives met with district staff members Monday to find some way to stem the virus' spread.
Dr. Kim Thorburn, the district's health officer, said she didn't yet need to declare a formal emergency.
"The alert has been sounded," she said. "It is an emergency, and people are responding to it."
Together, the health district and restaurant representatives hope to post fliers in grocery stores and schools about hepatitis A and also decide which types of food workers should be vaccinated. About 13,000 work in Spokane County's bars and restaurants.
An official meeting between restaurant representatives and the district is scheduled for Dec. 5.
Last week, Thorburn announced she planned to call a health emergency because of the county's high rate of hepatitis A, a liver disease that is spread by poor hygiene and fecal-oral contact.
Thorburn wanted to declare an emergency so she could require vaccinations for anyone who works in the food industry, intravenous drug users and jail inmates. She wanted to be able to order hospitals, insurance companies and restaurant owners to help pay for the vaccines.
The move was controversial because of the cost. The first shot costs $42; the second shot another $42.
As of Monday, 123 cases of hepatitis A have been confirmed in Spokane County, including one child who is now in the hospital.
That number compares to 20 cases for the same period last year. For every confirmed case, at least three others are probably infected without being diagnosed.
The virus is spread by infected people who don't wash their hands after using the restroom.
"We can't stress handwashing enough," Thorburn said. "It's very simple, what your grandmother always told you: When you use the bathroom, wash your hands."
The disease is infectious from about two weeks before symptoms begin until about two weeks after. Symptoms include yellowing of the eyes or skin, fatigue, diarrhea or nausea and loss of appetite.
About one-third of this year's cases are in IV drug users, and many involve those who've recently been in jail. Only one restaurant worker - at Sunset Junction, 1801 W. Sunset Blvd. - has been publicly identified as having the virus. Another worker who served food at a church event at the Spokane Valley United Methodist Church was also infected.
No cases have been tied to either food server, Thorburn said. But that could change, because the virus incubates for weeks before symptoms show.
Thorburn on Monday acknowledged that people were probably at a greater risk for infection from food served at home than in restaurants.
In fact, the Centers for Disease Control and Prevention don't even consider restaurant workers to be a high-risk group for hepatitis A.
Those high-risk groups include an infected person's household members or sexual partners; international travelers; and people living on Native American reservations, in Native Alaskan villages and other regions with endemic hepatitis A.
During outbreaks, other at-risk groups include day-care workers and children, sexually active gay men, and injectable drug users.
The immunization practices advisory committee of the CDC recommends hepatitis A vaccinations for people who plan to travel to countries with high or intermediate disease rates, for sexually active gay and bisexual men, for drug users, and for people with chronic liver disease.
Although Spokane's rate of hepatitis A is unusual for this area, it's not that high compared to other communities.
High-rate communities have outbreaks of as high as 2,000 cases per 100,000 people per year. Intermediate-rate communities have rates of between 50 and 200 cases per 100,000 people per year.
Spokane County's rate so far this year is only about 30 cases per 100,000. That rate could increase before year's end.
Large national outbreaks of hepatitis A happen about once a decade. The last outbreak happened in 1989, but the number of cases have been increasing recently.
More than 125,000 people come down with the virus every year in the United States. About one-third of Americans get the disease sometime during their lives. Hepatitis A costs about $200 million a year in medical bills and work loss.
Only about 100 people die every year in the United States from hepatitis A, the least fatal of all five types of hepatitis.
