question: What should I do if I suspect a potential case of reinfection?
answer: Although current understanding of reinfection remains limited, CDC is working with its partners to characterize the clinical features, transmissibility, and immunological profile around reinfection with SARS-CoV-2. Therefore, the guidance remains the same to reinfections as to primary infection with SARS-CoV-2. To further our shared understanding of reinfection, CDC has released the Investigative Criteria for Suspected Cases of SARS-CoV-2 Reinfection as well as the Common Investigation Protocol for Investigating Suspected SARS-CoV-2 Reinfection. This protocol is to support public health investigations conducted by interested institutions and jurisdictions. Clinicians with available specimens for suspected cases of reinfection meeting the above investigative criteria are also invited to contact CDC at eocevent461@cdc.gov after consulting with their local health department to pursue investigations with CDC support.
