Experts: California hepatitis A outbreak may linger

LOS ANGELES (AP) The hepatitis A outbreak in California that has claimed 17 lives may not have peaked and could take a year or more to abate, health officials said Thursday.

The contagious, liver-damaging illness has infected at least 568 people since last November, mainly in San Diego, Santa Cruz and Los Angeles counties.

People without symptoms can carry the illness and health officials suspect that transients in San Diego County spread it through homeless populations around the state. More than 480 of the illnesses, including all 17 deaths, have occurred in the county, which declared a public health emergency last month.

There have been 70 cases in Santa Cruz County, 12 in Los Angeles County and five elsewhere in the state, the Los Angeles Times (http://lat.ms/2xWRWGL) reported Thursday, citing state and county health departments.

Some communities have begun vaccinating the homeless but such preventative efforts may not immediately halt the outbreak.

"It's not unusual for them to last quite some time usually over a year, one to two years," said Dr. Monique Foster, a medical epidemiologist with the U.S. Centers for Disease Control and Prevention.

Hepatitis A spreads when someone comes in contact with an infected person's feces, sometimes when hands are not properly washed after going to the bathroom or changing diapers. The virus is then spread through food or objects. It can also be spread through sex or by sharing drug paraphernalia.

The city of San Diego has responded to the emergency by power-washing streets and installing hand-washing stations. The city announced this week that it will open an encampment for the homeless equipped with tents, showers, restrooms, food security and social services.

Santa Cruz County has distributed nearly 1,400 doses of vaccine but because it can take up to 50 days for infected people to show symptoms more cases are likely, said Jessica Randolph, the county's public health manager.

"I don't think the worst is over," she told the Times.
