Invasive pulmonary aspergillosis following human metapneumovirus infection in solid-organ transplant recipients: Another virus to add to the list.

There is increasing recognition that respiratory viral infections such as influenza, respiratory syncytial virus, parainfluenza virus, adenovirus, and SARS-CoV-2 can promote the development of invasive fungal pulmonary coinfections, particularly invasive aspergillosis, both in immunocompetent and immunocompromised patients. To date, there are no case reports exploring the role of human metapneumovirus as a risk factor for fungal coinfection. Below, we describe the case of a 63-year-old woman who received a kidney transplant and developed invasive pulmonary aspergillosis after a human metapneumovirus infection and discuss the possible phenomena that could favor this association.
