San Diego has declared a public health emergency to control a wildly spreading outbreak of the liver disease hepatitis A that has killed 15 people.
Infections have hospitalized nearly 400 more with the homeless population hit the hardest since the outbreak started last November.
Officials have attempted to use a combination of education and vaccination methods to prevent the spread of this virus, but the outbreak has only grown.
Hepatitis A can spread through ingesting food and drinks that have come in contact with feces from people who are already infected.
Officials are now moving fast to install hand-washing stations in areas more populated by homeless people to contain the spread of the deadly virus.
