We used commercially available ELISAs to test 68 samples from coronavirus disease cases and prepandemic controls from Benin. We noted ≤25% false-positive results among controls, likely due to unspecific immune responses elicited by acute malaria. Serologic tests must be carefully evaluated to assess coronavirus disease spread and immunity in tropical regions.
