The Los Angeles County Department of Public Health (Public Health) is investigating two additional cases of COVID-19 in Los Angeles County; the total number of cases for the county is now 13. Of these new cases, one is an additional positive case that was part of a group of travelers who were in Northern Italy. The other is a person who was working as a screener at the Los Angeles International Airport (LAX) Quarantine Station and has a link to the previously reported case that was most likely exposed by an infected traveler at the same location. Public Health has asked the Center for Disease Control and Prevention for assistance investigating positive cases among the two screeners at LAX.

Public Health is identifying persons who may have had close personal contact with these individuals, including any friends, family members or health care professionals, to assess and monitor them for signs and symptoms of illness has begun. All confirmed cases are being isolated and close contacts will be quarantined.

There are no known public exposure locations.

"We will continue to see more cases of COVID-19," said Barbara Ferrer, PhD, MPH, MEd, Director of Public Health. "We continue to urge everyone to do their part: stay home if you are sick and keep your children home if they are sick; take time now to plan for the possibility of school and business closures, and be sure to follow any additional directives issued by Public Health and/or local officials. By working together, we can try to slow the transmission of novel coronavirus," she added.

Public Health will continue to actively monitor this situation and provide updates to the public as needed.

Public Health continues to recommend that the public do the following to protect themselves and others from respiratory illnesses:

• Stay home when you are sick.

• Wash your hands often with soap and water for at least 20 seconds, especially after going to the bathroom; before eating; and after blowing your nose, coughing, or sneezing.

• Avoid touching your eyes, nose, and mouth with unclean hands.

• Limit close contact, like kissing and sharing cups or utensils, with people who are sick.

• Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe.

• Cover your cough or sneeze with a tissue, then throw the tissue in the trash. If you do not have a tissue, use your sleeve (not your hands).

• Facemasks are most effective when used appropriately by health care workers and those directly caring for people who are sick and by people who are sick (source control).

• Get a flu immunization to prevent influenza if you have not done so this season.
