Source of Hep A outbreak unknown

I enjoy working in the field of public health, it’s challenging and exciting. I have had the opportunity to work with some incredible epidemiologists, public health inspectors, and public health nurses, the work they do is critical during outbreaks. I have had some experience dealing with foodborne outbreaks of Hepatitis A and due to its long incubation period, it’s a nightmare trying to get information from ill persons to identify a common source.

Outbreak News Today reports

In a follow-up on the hepatitis A outbreak in San Diego County, CA, the number of cases reported this year has climbed to 312, including 10 fatalities, according to latest health department data.
Of the cases, nearly seven out of 10 patients required hospitalization for their illness (215).
The County of San Diego Health and Human Services Agency says the investigation into the outbreak is ongoing.
It has been challenging because of the long incubation period of the disease (15 to 50 days) and the difficulty experienced to contact many individuals sickened with the illness who are homeless and/or illicit drug users. To date, no common source of food, beverage, or other cause has been identified; as a result, the source of the outbreak remains undetermined.
