Respiratory Tract Reinfections by the New Human Metapneumovirus in an Immunocompromised Child
نویسندگان
چکیده
The human Metapneumovirus (HMPV), a new member of the Paramyxoviridae family, has been recently associated with respiratory tract infections in young children. We report the case of a young, immunocompromised child who had severe lower respiratory tract infections during two consecutive winter seasons caused by genetically distinct HMPV strains.

BACKGROUND Providing anesthesia to immunocompromised patients introduces unique challenges, including difficulty in detecting respiratory infections. Detailed preoperative evaluation and preparation for perioperative complications is crucial. Human metapneumovirus is a common but lesser known respiratory virus that can lead to pneumonia and respiratory compromise and is challenging to detect in...

Globally, as a leading agent of acute respiratory tract infections in children <5 years of age and the elderly, the human metapneumovirus (HMPV) has gained considerable attention. As inferred from studies comparing vaccinated and experimentally infected mice, the acquired immune response elicited by this pathogen fails to efficiently clear the virus from the airways, which leads to an exaggerat...

Human metapneumovirus (hMPV) and respiratory syncytial virus, its close family member, are two major causes of lower respiratory tract infection in the paediatric population. hMPV is also a common cause of worldwide morbidity and mortality in immunocompromised patients and older adults. Repeated infections occur often, demonstrating a heavy medical burden. However, there is currently no hMPV-sp...
