Marin Confirms Additional COVID-19 Cases

Residents can slow disease spread with simple, everyday behaviors

San Rafael, CA – The Marin County Department of Health and Human Services (HHS) has confirmed that two additional Marin residents have tested positive for COVID-19, the novel coronavirus, bringing the local total to three.

Both individuals lived with Marin’s first reported case, who was a passenger on the Grand Princess – Mexican Rivera cruise ship that experienced an outbreak of COVID-19. The newly diagnosed cases had been isolated in their home and are experiencing mild symptoms but do not require hospitalization.

Marin HHS will not release additional information about the patients or the treating hospital to protect the medical privacy of the patients and family.

“Unfortunately, this doesn’t come as a surprise,” said Dr. Matt Willis, Marin County’s Public Health Officer. “These individuals were at high risk based on very close contact.”

Testing for two additional household members is pending.

“We fully expect to see more cases in Marin,” Willis said. “Given the number of cases in the Bay Area, we will see transmission within our community. Our ultimate goal is to limit the trajectory of COVID-19.”

The news comes on the day Marin opened a COVID-19 testing facility to enhance countywide capacity for testing. Individuals referred by their physicians can complete drive-through testing without having to get out of their vehicle.

The best way to prevent the spread of germs in the community, whether flu or COVID-19, is to practice good hygiene:

·       Wash your hands frequently with soap and water for at least 20 seconds, especially before eating, after blowing your nose, coughing, or sneezing;

·       Use an alcohol-based hand sanitizer when soap and water is not available;

·       Cover your cough or sneeze with a tissue or crook of your elbow (not your hands).  If you use a tissue, throw it away and wash your hands afterward;

·       Avoid touching your face;

·       Stay home from work or school if you have a fever or are feeling sick;

·       Avoid close contact with people who are sick;

·       Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe;

·       Get your flu shot to protect against flu.
