We recently experienced two cases of pneumonia in which HPIV-1 was isolated from bronchoalveolar lavage (BAL) fluid and confirmed by a multiplex polymerase chain reaction (PCR) test (Fast Track Diagnostics Resp 21 Kit, Silema, Malta), which detects the following respiratory pathogens: influenza A and B viruses; coronaviruses NL63, 229E, OC43, and HKU1; human parainfluenza viruses 1, 2, 3, and 4; human metapneumovirus A/B; rhinovirus; respiratory syncytial virus A/B; adenovirus; enterovirus; human parechovirus; bocavirus; and Mycoplasma pneumoniae. However, previous reports that investigated virus infections in patients with pneumonia used nasopharyngeal or oropharyngeal swabs to detect viruses, which raises the possibility of upper respiratory tract infection by HPIV. Furthermore, these studies include mixed viral and bacterial infections, and the clinical characteristics of the immunocompetent patients with primary HPIV pneumonia are not fully known.	./cache/cord-304277-aek6mvdw.txt	./txt/cord-304277-aek6mvdw.txt
