COVID-19 and Pulmonary Coinfection: A Case Series.

Objectives: In COVID-19 patients, bacterial and fungal pulmonary coinfections, such as , , , or have been reported, but to our knowledge, no case has been reported due to .

Patients And Methods: We describe three cases of coinfections occurring during the 4th wave of COVID-19 in Martinique (French West Indies).

Results: All three cases were fatal; thus, has to be considered as a potentially severe coinfection agent.

Case Report: Pulmonary Leptospirosis Misdiagnosed as COVID-19.

We report the case of an 83-year-old woman with acute, febrile respiratory failure resulting from interstitial pneumonia that required high-flow oxygen therapy. This clinical picture, associated with the ongoing epidemiological situation, initially guided us toward a diagnosis of COVID-19. Based on SARS-CoV-2 reverse transcription-polymerase chain reaction negativity and the absence of anti-SARS-CoV-2 antibodies, a search for a differential diagnosis was conducted that led us to conclude a diagnosis of severe pulmonary leptospirosis This case highlights the need to engage in early discussions about differential diagnoses, including neglected tropical and subtropical diseases, during the COVID-19 era.
