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 ]
In the laboratory, adenovirus can be identified with antigen detection, polymerase chain reaction (PCR), virus isolation and serology. Even if adenovirus is found to be present, it may not be the cause of any symptoms. Some immunocompromised individuals can shed the virus for weeks and show no symptoms. [39]

How long do symptoms last? They peak at 24 to 48 hours but can last up to 72 hours, says Dr. Dibba. Norovirus tends to hit hard and then fade fairly quickly. Symptoms do ramp up in intensity, however.
Adenoiditis may produce cold-like symptoms. However, adenoiditis symptoms often persist for ten or more days, and often include pus-like discharge from nose. The infection cause is usually viral. However, if the adenoiditis is caused by a bacterial infection, antibiotics may be prescribed for treatment.
