WHAT DOES 'PRESUMTIVE POSITIVE' MEAN?

All of the Nevada cases are "presumptive positive," meaning they tested positive at the local level and now need to be confirmed by the Centers for Disease Control and Prevention.

WHAT DO WE KNOW ABOUT THE CASES?

To protect the privacy of the patients involved, public information about their cases is limited. Local health officials and representatives say they continue to work with federal agencies when it comes to handling coronavirus within the state. Here's what officials were able to share about these cases.

The first reported case in Clark County involves a veteran who is over 50 years old. He is currently in the hospital and has been quarantined. The health district says that the man does have an underlying health condition and they are hoping for the best.

Information on the second reported case in Clark County is set to be shared on Monday, according to a tweet from Southern Nevada Health District.

The first reported case in Washoe County involves a man in his 50s who was linked to the Grand Princess cruise ship outbreak. Officials say his condition is stable and he is self-isolating at home.

The second reported case in Washoe County involves a man in his 30s. He is isolated at home, and the county says his symptoms appeared after his only known travel, which was to Santa Clara, Calif.

WHAT HAS THE RESPONSE BEEN FROM OFFICIALS?

On Saturday, Gov. Steve Sisolak announced that an emergency regulation to help make preventative measures more accessible to Nevadans. The measure ensures no out-of-pocket costs for preventative services related to COVID-19, such as testing. The measure also says insurance companies must cover the cost of COVID-19 immunization when it becomes available.

HOW DO WE PREVENT THE SPREAD?

There is no vaccine to prevent COVID-19 at the moment, so health officials have been emphasizing steps to help prevention. Good practices like washing your hands and staying home from work when you are sick are the repeated message.

The CDC says:

Avoid close contact with people who are sick.

Avoid touching your eyes, nose, and mouth.

Stay home when you are sick.

Cover your cough or sneeze with a tissue, then throw the tissue in the trash.

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

Follow CDC’s recommendations for using a facemask.

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. If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty.



When it comes to wearing facemasks, the CDC does not recommend them as preventive protection. Here's what the agency says:

The CDC does not recommend that people who are well wear a facemask to protect themselves from respiratory diseases, including COVID-19.



Facemasks should be used by people who show symptoms of COVID-19 to help prevent the spread of the disease to others. The use of facemasks is also crucial for health workers and people who are taking care of someone in close settings (at home or in a health care facility).

UPDATE MARCH 9: The Southern Nevada Health District says the second presumptive positive case of coronavirus disease 2019 (COVID-19) is a woman in her 70s who is currently hospitalized and in isolation.

SNHD also says two adults have been identified as close contacts of this individual and are being asked to self-quarantine for 14 days.

The patient is reporting in-state travel prior to developing symptoms, the Health District says. It is working with its health care partners on this ongoing investigation.
