CDPH declares state of emergency over Hepatitis A outbreak

California has declared a state of emergency to help control the state’s hepatitis A outbreak and are taking action to increase adult hepatitis A vaccine supplies.

“Vaccinating people at risk of exposure is the most effective tool we have to prevent the spread of hepatitis A infection during an outbreak,” said California Department of Public Health (CDPH) Director and State Public Health Officer Dr. Karen Smith.

CDPH has already distributed nearly 80,000 doses of the vaccine obtained through the federal vaccine program, but such supplies must be increased to continue the fight against the outbreak.

California Governor Edmund G Brown Jr.’s state of emergency declaration on Friday will allow the public health department to immediately purchase additional vaccines directly from manufacturers and coordinate distribution to people at greatest risk in affected areas.

The adult hepatitis A vaccine is different than the one given to children, of which there enough supplies.

The risk of hepatitis A infection is associated with poor sanitation and hygiene and is transmitted through ingestion of contaminated food and drink or through direct contact with an infectious person.

The current outbreak has largely impacted people experiencing homelessness and some illicit drug users. The virus can live for months in a contaminated environment, especially where there’s lack of good sanitation.

To control this outbreak and prevent further spread, CDPH recommends the vaccination of people in affected areas who are homeless or using illicit drugs.

CDPH also recommends vaccination of people who have frequent, close contact with at-risk populations in affected areas. CDPH is working with impacted counties to monitor the outbreak and implement vaccination efforts and is also providing guidance on improving sanitation, including access to handwashing facilities and toilets, to lessen the spread of the virus.

“Local public health officials are working hard to offer vaccines to people who are at the most at risk of infection, including homeless Californians,” said Dr. Smith. “Today’s order will help ensure communities can continue to deliver the vaccines where they are needed most.”
