There are three levels to a possible COVID infection:
- Person Under Investigation, also PUI: Anyone who is being checked for the virus, or who was under investigation but tested negative.
- Presumptive Positive: Anyone positive by testing at the local or state level. Presumptive positive cases must be confirmed by the CDC.
- Laboratory-confirmed case has tested positive for the virus at the CDC laboratory.
