Bacterial infections can present simultaneously with COVID-19 or occur later during the course of the disease, worsening clinical conditions of patients who were recovering from primary viral pneumonia. Information regarding the prevalence of bacterial coinfection or superinfection is scant [28,44,45]. According to the available reports, prevalence of bacterial infections in patients with COVID-19 ranges between 1% and 10% [28,44,46]. In these reports, bacterial infections were due to Gram-negative bacteria including Enterobacterales and nonfermenting rods [28,44]. It is of note that up to 98% of COVID-19 patients in available experiences received intravenous broad-spectrum empirical antibiotics [28,44,45,47], probably reflecting the frequent inability to exclude the presence of bacterial coinfection at the onset of severe clinical presentations of COVID-19. This could have possibly lowered the overall prevalence of bacterial superinfections.
