CDC finds hepatitis A was carried from San Diego to AZ shelter
On Tuesday, Sacramento authorities urged recent patrons Haggis Oaks Golf Course to immediately ask their doctors about taking the post-exposure hepatitis A vaccination after an employee of a restaurant at the course was confirmed infected.
Also on Tuesday, San Diego officials reported the local confirmed victim count had reached 418, with 70 percent requiring hospitalization and 17 having died.
Two-thirds of the sick in San Diego are designated homeless or drug users, meaning 33 percent of the confirmed victims are not members of those marginalized populations.
On Wednesday, San Diego officials reported the state had finally OK’d an emergency request they had filed Sept. 20 seeking temporary permission paramedics to be allowed to help vaccinate at-risk vaccinations. About 54,000 people in the county have been vaccinated through emergency programs.
Today, epidemic investigators from the federal Centers for Disease Control and Prevention are scheduled to present research documenting that an outbreak of hepatitis A at a Maricopa County, AZ, homeless shelter in February this year coincided with the arrival of a person from San Diego. At least three samples from the Arizona shelter were molecularly identical to the virus strain in San Diego victims.
Restaurant customers must act now
People who ate or drank at MacKenzie’s Sports Bar and Grille from Sept. 12 through Sept. 22 should ask their doctors about taking the post-exposure vaccine, Sacramento County Public Health Officer Olivia Kasirye said earlier this week.
There is only a two-week window of opportunity after exposure when the vaccine is effective. People who ate and drank at the restaurant are at relatively high risk of infection because it is known that the infected employee handled food.
For those who miss the chance for the post-exposure vaccine, it is important to watch for symptoms in the coming weeks because the incubation time for the virus in humans is 15 to 50 days, according to the CDC.
Sacramento officials reported it is not known how the restaurant employee became infected.
Numbers increasing despite control measures
In April this year, San Diego officials reported they had confirmed 42 hepatitis A cases in the region since November 2016, quadruple the monthly average usually reported. Of those people, 36 had symptoms so severe they required hospitalization. Two of them died.
Efforts in the ensuing months to eradicate the highly contagious virus, which can lead to liver damage and failure, have included cleaning human waste from streets in areas frequented by homeless people and dismantling so-called encampments where they sleep.
Some have been working to increase accessibility to restrooms and hand-washing facilities for the high-risk populations. Other than being vaccinated, public health officials say frequent and thorough hand washing is the most effective way to curb the spread of the hepatitis A virus.
On Wednesday, the San Diego City Council’s Public Safety and Livable Neighborhoods Committee heard updates on the situation from the city’s assistant chief operating officer and the county’s public health officer.
