Case Report: Challenges of Diagnosing Malaria in Returning Travelers at the Height of COVID-19 Pandemic

Abstract

In 2021, we treated three patients in Southern California who contracted malaria while traveling in Uganda. Two patients visited the Nile River in Uganda in the months of July and August 2021, and upon returning to the United States, diagnosis was delayed due to limited access to care during the COVID-19 pandemic. One of the patients developed severe malaria, and the second developed parasitemia after he stopped taking malaria prophylaxis. The third patient, who traveled to Kampala, Uganda, in December 2021 returned home and was admitted for chronic medical conditions. Later in the clinical course, he developed symptoms consistent with malaria, but due to SARS-CoV-2 diagnosis, there was no suspicion of malaria infection until it was incidentally discovered while performing a blood manual differential. All patients were treated for malaria and recovered uneventfully.
