Adenovirus gastroenteritis is a diarrhea illness, a type of adenovirus infection caused by certain types of Adenoviruses.[1] It generally presents with fever, vomiting, and diarrhea.[1] Sometimes there are symptoms of a respiratory tract infection.[1] Symptoms typically persist for 8-12 days.[3]

It is caused typically by types 40/41 (species F) of the virus Adenoviridae.[2] Other adenoviruses associated with gastroenteritis include types G52 and some members from the D species.[2] Depending on the type, there may or may not be an associated respiratory tract infection.[1] Spread is generally via the fecal-oral route.[1] The most common complication is dehydration.[2]

Treatment is supportive, with replacing lost fluids by mouth and injection, zinc supplementation, and adequate nutrition.[1] Most cases get better without any specific treatment.[2] Prevention requires improved water quality, sanitation, and hygiene.[1]

It is a common cause of diarrhea globally.[4] Up to 10% of diarrhea in children are caused by adenoviruses.[3] In 2016, the Global Burden of Disease Study estimated that globally, around 75 million episodes of diarrhea among children under the age of five-years, were attributable to adenovirus infection, particularly in low and middle income countries.[1]

Signs and symptoms

Adenovirus gastroenteritis generally presents with fever, vomiting, and diarrhea.[1] Depending on the type, there may or may not be an associated respiratory tract infection.[1] Symptoms typically persist for 8-12 days.[3]

Cause and mechanism

Although other types may be implicated, generally types 40/41 (species F) of the virus Adenoviridae has been established as a cause of severe diarrhoea in very young children in low and middle income countries.[1] Other adenoviruses associated with gastroenteritis include types G52 and some members from the D species.[2] Adenoviruses -12, -18, and -31 infection have also been implicated as causes of gastroenteritis.[5] Spread is generally via the fecal-oral route.[1]

Complications include chiefly dehydration, and infrequently colitis, pancreatitis and hepatitis.[2]

Treatment and prevention

Treatment is supportive, with replacing lost fluids by mouth and injection, zinc supplementation, and adequate nutrition.[1] Most cases get better without any specific treatment.[2] Prevention requires improved water quality, sanitation, and hygiene.[1]

Epidemiology

It is a common cause of diarrhea globally, along with rotavirus, norovirus and astrovirus.[4] Up to 10% of diarrhea in children are caused by adenoviruses.[3] It affects particularly under one-year olds, but the numbers affected vary significantly year by year.[1] The exact number of people affected is not known; reliable rapid testing is not widely available.[1] It is a frequent cause of hospital admissions.[1] In 2016, the Global Burden of Disease Study estimated that globally, around 75 million episodes of diarrhea among children under the age of five-years, were attributable to adenovirus infection, with a mortality of near 12%.[1]

History

Adenoviruses type F40/41 were first detected in 1983 by de Jong and Unhoo.[2]
