Shasta County's Response to Local Emergencies



  • Social Distancing is a way to keep people from interacting closely or frequently enough to spread an infectious disease.
  • Quarantine separates and restricts the movement of people who have been exposed to a contagious disease to see if they become sick. It lasts long enough to ensure the person has not contracted an infectious disease. In the case of COVID-19, the quarantine period is 14 days.
  • Isolation prevents the spread of an infectious disease by separating people who are sick from those who are not. It can last as long as the disease is contagious.
  • Community Transmission is a form of transmission where patients get an infectious disease without being exposed to anyone who is known to be infected and without having travelled to countries in which there is a current outbreak.
