The Centers for Disease Control and Prevention will be coming to San Diego next week to discuss ways to fight the region's deadly Hepatitis A outbreak.

The San Diego County Health and Human Services updated the number of people infected with the virus Tuesday.

Seventeen people have died and 461 cases have been confirmed, according to county officials. Of those cases, there have been 315 hospitalizations.

A third of the cases involved people who used illicit drugs and are considered homeless. Of the cases, 25 percent are neither homeless or drug users.

County officials have not identified the locations of cases but did report to the County Board of Supervisors on Tuesday that there have been 38 cases in the unincorporated jurisdiction of the county. Of those, half were homeless, illicit drug users or both.

As of September 23, more than 42,000 vaccines have been administered in San Diego County. Close to 700 people were given the vaccine as a precaution after exposure to the virus.

Officials said 22,406 were given by health care systems or pharmacists but 15,662 vaccines were given by county staff in the field, in jails or detention centers or the county psychiatric hospital.

The City of San Diego has installed new bathrooms in the East Village to help curb the spread of the virus. That area has a high concentration of transients.

Those restroom facilities will be maintained at least twice a day, and will be monitored by full-time security, the city said.

There are now 22 public restroom facilities in downtown San Diego, as listed here.

City crews have also sanitized sidewalks in the downtown area and installed hand-washing stations.

County health officials have also notified 14,000 food facilities in the area as well as agricultural growers and public pools.

Hepatitis A is a liver infection caused by a virus that is highly contagious. The Hepatitis A virus can be contracted by touching objects or eating food that someone with the Hepatitis A infection has handled or by having sex with someone who has an HAV infection.

Some people get the virus but have no symptoms. Signs of infection include fever, fatigue, nausea, loss of appetite, yellowing of the eyes (jaundice), stomach pain, vomiting, dark urine, pale stools, and diarrhea. Adults are more likely to have symptoms than children.

The California Department of Public Health suggests anyone who has been exposed to the virus, and who has not been previously immunized for Hepatitis A, should consider getting vaccinated no later than two weeks after exposure.
