Background: Human metapneumovirus is a recently discovered RNA virus that typically causes respiratory disease in children. It has been linked to severe lower airway disease in hematopoietic stem cell and solid-organ transplant recipients. hMPV infection in a large population of patients with underlying cancer and varying degrees of immunosuppression has not been reported. We sought to characterize hMPV infection in patients with cancer.
Methods: Review of all cases of hMPV infection from two seasons (2005-6 and 2006-7) detected by DFA and/or real-time PCR at MSKCC, a tertiary cancer center in New York City.
Results: Among MSKCC patients with cancer, 51 (2.7%) of 1899 patients were positive for hMPV, including 3.2% with hematologic neoplasm and 1.7% with solid tumors. More children (4.5%) were positive than adults (2.2%). PCR detected twice as many cases as DFA. Cough and fever were common complaints. The longest shedding period was 80 days. 40 patients received radiographic evaluation; of these, 22 showed abnormalities including patchy (11), ground glass (5), and interstitial infiltrates (4).
Conclusions: hMPV causes a nonspecific respiratory illness and was found in more than 2% of all tested persons with cancer. PCR detected substantially more cases than DFA. Unlike previous reports, we observed no fatalities due to hMPV, including 22 HSCT recipients with the infection.

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.

Background: Acute lower respiratory tract infections (ALRIs) remain the leading infectious cause of death among children < 5 years, with viruses contributing to a large proportion of cases. Little is known about the epidemiology and etiology of viral ALRI in rural Bangladesh.
Methods: We enrolled 3- to 23-month-old children with ALRIs attending a subdistrict hospital outpatient clinic in Sylhet district in Bangladesh.

Introduction: Acute lower respiratory infections (ALRIs) are a major contributor to the global infectious disease burden and a common cause of hospitalisation for children under 2 years. We compared clinical severity in children hospitalised with respiratory syncytial virus (RSV), parainfluenza virus (PIV), human metapneumovirus (hMPV) and influenza virus (IFV).
Methods: We used a probabilistically linked population cohort born in Western Australia between 2010 and 2020 and hospitalised before the age of 2 years.
