We used a combination approach of conventional virus isolation and molecular techniques to detect human metapneumovirus (HMPV) in patients with severe acute respiratory syndrome (SARS). Of the 48 study patients, 25 (52.1%) were infected with HMPV; 6 of these 25 patients were also infected with coronavirus, and another 5 patients (10.4%) were infected with coronavirus alone. Using this combination approach, we found that human laryngeal carcinoma (HEp-2) cells were superior to rhesus monkey kidney (LLC-MK2) cells commonly used in previous studies for isolation of HMPV. These widely available HEp-2 cells should be included in conjunction with a molecular method for cell culture followup to detect HMPV, particularly in patients with SARS.

After ending the three-year zero COVID policy in China, the epidemiology of other respiratory pathogens has been affected. This study aimed to characterize of common respiratory pathogen infections in pediatric patients hospitalized for acute respiratory tract infections (ARTIs) in Suzhou before and after ending the zero COVID policy. Nasopharyngeal aspirates (NPAs) were obtained from children with ARTIs (aged ≤ 16 years) at the Children's Hospital of Soochow University for the detection of respiratory syncytial virus (RSV), influenza A (FluA), FluB, human parainfluenza virus (HPIV), adenovirus (ADV), human rhinovirus (HRV), bocavirus (BoV), human metapneumovirus (HMPV), and mycoplasma pneumoniae (MP).

BACKGROUND Human metapneumovirus (hMPV), classified in the Pneumoviridae family, is primarily known for causing lower respiratory tract infections in children, the elderly, and immunocompromised individuals. However, rare instances have shown that hMPV can also affect other systems, such as the cardiovascular system, leading to conditions like myocarditis. CASE REPORT We describe a 68-year-old man with a medical history of diabetes, hypertension, and liver cirrhosis who presented to the Emergency Department (ED) exhibiting symptoms of fever, cough, and dyspnea.

Objectives: Human metapneumovirus (hMPV) is recognized as a significant cause of acute respiratory infections among infants under 5 years of age.
Methods: Nasal swabs collected from January 2021 to June 2024 were screened to detect hMPV using reverse transcription-quantitative polymerase chain reaction. Furthermore, representative positive samples were sequenced and subjected to phylogenetic analysis.

Unlabelled: Though usually self-limiting, viral respiratory infections can escalate to severe cases requiring admission to a pediatric intensive care unit (PICU). This study aims to examine the proportional incidence, affected age ranges, viral pathogens involved, associated severity measures, and the impact of the COVID-19 pandemic on their incidence and virus distribution. This retrospective cohort study conducted in a tertiary care center (2011-2021) reviewed all pediatric patients admitted to PICU with laboratory-confirmed viral respiratory infection.

Background: Studies on late community-acquired respiratory virus (CARV) infections in long-term allogeneic hematopoietic stem cell transplantation (allo-HCT) survivors are scarce, creating knowledge gaps on the epidemiology, risk of progression to lower respiratory tract disease (LRTD), and conditions linked to poor outcomes.
Patients And Methods: We included consecutive CARV infection episodes occurring up to six months after allo-HCT registered in our database from December 2013 to June 2023 at two Spanish transplant centers.
Results: Among 426 allo-HCT recipients, 1070 CARV episodes were recorded, 791 (74%) with only upper respiratory tract disease (URTD) and 279 (15%) progressing to LRTD, at a median of 18.
