Community-acquired bacterial pneumonia (CABP) remains a significant cause of morbidity and mortality worldwide. Antimicrobial resistance, including in pathogens that cause CABP, continues to spread at an alarming rate. Because of these factors, the development of new antibiotic classes is urgently needed. ⋯ Available in both oral and intravenous formulations, lefamulin has potent in vitro activity against both typical and atypical CABP pathogens. The first pleuromutilin to be used systemically in humans, lefamulin has a unique mechanism of action that inhibits protein synthesis by preventing the binding of tRNA for peptide transfer. This review summarizes the available data on lefamulin, including recent evidence from 2 phase III clinical trials (LEAP 1 and LEAP 2), and discusses its potential role in the treatment of CABP.

Few pediatric cases of coronavirus disease 2019 (COVID-19) have been reported and we know little about the epidemiology in children, although more is known about other coronaviruses. We aimed to understand the infection rate, clinical presentation, clinical outcomes, and transmission dynamics for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), in order to inform clinical and public health measures. ⋯ Children appear to have a low observed case rate of COVID-19 but may have rates similar to adults of infection with SARS-CoV-2. This discrepancy may be because children are asymptomatic or too mildly infected to draw medical attention and be tested and counted in observed cases of COVID-19.

To explore and describe the current literature surrounding bacterial/fungal coinfection in patients with coronavirus infection. ⋯ Despite frequent prescription of broad-spectrum empirical antimicrobials in patients with coronavirus-associated respiratory infections, there is a paucity of data to support the association with respiratory bacterial/fungal coinfection. Generation of prospective evidence to support development of antimicrobial policy and appropriate stewardship interventions specific for the COVID-19 pandemic is urgently required.
