San Diego has tried to control the outbreak with street cleaning and providing more portable toilets in the infected areas. In Los Angeles County, public health has worked with agencies like the Midnight Mission.
"We had a vaccination clinic where we gave out 70 vaccinations to our workers who are interacting with the homeless community," said Georgia Berkovich of Midnight Mission.
"We serve nearly a million meals a year here so we are a point of contact for a lot of people in our community."
Hepatitis A is a liver disease that can be transmitted through eating bad or contaminated food. It can also be transmitted by being in contact with someone who is infected.
