Quoted By:
There's people who had symptoms of infection, tested positive, improved, tested negative twice, felt fine for several months, then experienced new symptoms and tested positive again. Was the original positive test wrong (in some cases, both a PCR and antibody test)? Were the two negative tests wrong? Were they reinfected or did they relapse? Give how quickly antibody levels fall after the initial infection, it's pretty clear reinfection is not only possible, but probable.
