A fatal case of COVID‐19 breakthrough infection due to the delta variant

ABSTRACT

COVID‐19 infections that occur at least 2 weeks after complete vaccination are known as breakthrough infections. Herein, we report a clinical case resembling breakthrough infection that was correlated with a higher score of COVID‐19 pneumonia on chest computed tomography (CT) in a patient who resulted positive for the delta variant and who died during the hospitalization. Although currently approved vaccines have shown great efficacy in reducing COVID‐19 severity, COVID‐19 variants may represent increasing concerns. Breakthrough infections with COVID‐19 pneumonia are also possible especially in older people and in patients with comorbidities. Therefore, improvement of therapy and management of patients with COVID‐19 should be not overlooked.
