Novel coronavirus disease (COVID-19) become one of the most important
global health issues. With increasing the number of COVID-19 patients,
the possibility of occurring re-infection in recovered patients is
arising. There is still not proven that the recuperated COVID-19
patients are immunized against the SARS-CoV-2. Herein, we reported a
case of COVID-19 who was previously infected with the gastrointestinal
form of the disease. The patient was infected again after 97 days of the
initial GI symptoms of the disease or 82 days of the post negative test.
RT-PCR was also positive in the virus detection. This is the first
report of COVID-19 patient with the longest period of time of
re-infection which has been reported yet.
