Dear editor,rnAdults with community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) are prone to necrotizing pneumonia, bacteremia, and high mortality. Several studies have reported the disease worldwide, but only a few cases of CA-MRSA pneumonia in children and adolescents have been reported in China.[1] No CA-MRSA was detected in the pathogens of community-acquired respiratory tract infections in Chinese adults from 2009 to 2010. During the influenza epidemic, such as COVID-19, viral infections are followed by repeated bacterial infections, and methicillin-sensitive Staphylococcus aureus (MSSA) and MRSA pneumonia are known complications.[2] Thus, identifying and treating these infections is a tricky clinical issue. A case of CA-MRSA pneumonia with bloodstream infection and pneumothorax was successfully treated in our hospital in January 2018. Herein, we presented a case report based on previous studies.
