COVID-19 cases in schools

Clark County Public Health works closely with local schools and school districts to prevent and mitigate the spread of COVID-19 on school campuses. Schools notify Public Health anytime someone who has tested positive for COVID-19 has been on the campus while potentially contagious.

Public Health works with schools to identify close contacts who may have been exposed. Schools will notify those students and staff who are identified as close contacts and provide instruction on quarantine. People in quarantine should not leave home except to seek medical care. They should not go to work, school or child care facilities, and they should not participate in any social or community activities.

Everyone who tests positive for COVID-19 is instructed to isolate at home until they are no longer contagious, which is typically at least 10 days from the time symptoms began.

COVID-19 outbreaks in schools

Clark County Public Health is providing information about COVID-19 outbreaks at local public and private K-12 schools. Outbreaks indicate that the virus is spreading between people (virus transmission) in the school.

An outbreak in a school setting is considered when:

  • There are two or more laboratory-positive COVID-19 cases among students or staff.
  • The cases have symptoms beginning within 14 days of each other.
  • The cases are epidemiologically linked in the school (i.e. were within 6 feet of each other for 15 minutes or more, or were in the same classroom, pod, transportation or school-sponsored extracurricular location).
  • The cases do not share a household and were not identified as close contacts in another setting.

If the above criteria is not met, the cases will not be considered an outbreak in the school setting and will not be included on this webpage.

For each school outbreak, Public Health will provide the following information:

  • Number of cases: Total number of cases, and breakdown of the number of cases among students and staff.
  • First exposure date: The first known date a COVID-19 case was on campus while potentially contagious.
  • Last exposure date: The last known date a COVID-19 case was on campus while potentially contagious.
  • Monitoring end date: The date Public Health’s outbreak monitoring ends. This date may change if additional cases are identified. Public Health monitors outbreaks for 28 days from the last exposure at the school.

Last updated June 17. This will be the final update for the 2020-21 school year. This data will not be updated during summer months.
