Human adenovirus 41 (HAdV-F41), is an enteric Adenovirus, a nonenveloped virus with an icosahedral nucleocapsid containing a double-stranded DNA genome.[1]
It can particularly target the gastrointestinal tract to cause gastroenteritis, with symptoms similar to rotavirus gastroenteritis and norovirus.[2] It may be present in the gut without causing symptoms and can be detected by using molecular based assays and enzyme immunoassay.[2][3] As of August 2022, human adenovirus 41 has been identified in a majority of small children with hepatitis of unknown cause in 2 case series.
Classification
Human adenovirus 41 belongs to the Adenoviridae family, and along with human adenovirus 40, is a member of species human mastadenovirus F.[4][5]
Pathology
It can particularly target the gastrointestinal tract to cause gastroenteritis in very young children.[3] Symptoms appear similar to rotavirus gastroenteritis and norovirus.[2] It may be present in the gut without causing symptoms.[3]
In an investigation of 5 children with an inflammation of the liver (hepatitis) of unknown cause at Birmingham, Alabama in October 2021, all turned out to have human adenovirus 41.[6] In August 2022, 9 children in a U.S. case series of hepatitis of unknown cause[7] and 27 of 30 children in a U.K. case series with hepatitis of unknown cause who underwent molecular testing[8] tested positive for human adenovirus type 41 in a sample. It was unclear whether human adenovirus 41 was the cause, however.
Diagnosis
It cannot be detected using traditional cell culture isolation,[3] but can be detected by using molecular based assays and enzyme immunoassay.[2]
Epidemiology
Globally it is a significant cause of gastroenteritis, particularly in low and middle income countries,[5][9] but less common than rotavirus and norovirus.[10] How frequently it occurs in sewage and drinking water is not known.[3] Type 40 is less common.[9]
History
It was first identified in 1983.[11]
