Severe pneumonia due to Legionella and SARS-CoV-2 co-infection necessitating medical evacuation from a cargo ship.

Based on the results of WGS, there may be a high likelihood that I Legionella i infection occurred outside Japan, whereas SARS-CoV-2 infection transpired during the ship's port calls in Japan.
