Virus question
------------------------------------------------------------------------- -------
A 5 y/o male is brought to ER by his mother complainig of headache and fever.His parent were concern with the child's frequent diarrhea and elevated body temperature.Symptoms began approx 2 days previous. the Parent report that children at a daycare center where the child attends were similsrly ill.
stool was collected for culture; examined for WBC; had a rapid virus antigen test performed on it, and an ova and parasite examination. A CBC count was within normal limits. The patien was not acutly ill and was discharged with supportive care instruction provided to the parents.The stool culture was subsequently reported out as negative for bacterial enteric pathogens.The stool was negative for WBC.The ova and parasite examination was negative.The rapid virus antigen test was however positive. The causative agent of this patient's gastroenteritis is a DNA virus that is 70 nm in diameter. The most probable cause of this patient's gastroenteritis is
(A) Adenovirus
(B) Rotavirus
(C) Parvovirus
(D) Norwalk virus
(E) Hepatitis A

true...adenovirus is a major cause of gastroenteritis, as well as conjunctivitis. and it and parvo are the only DNA viri on here.

yes picture is classic for rotaviruses, but they are dsRNA, so only that's why i have to go with adeno.

DNA are HHAPPP! (Happy)
Hep B
Herpes
Adeno
Papova
Papilloma
Pox
Of these, you have to be naked to a PAP smear
naked DNA viruses = PApova, Adeno, PApilloma
I think this is right, yes? There is no easy way that I know of to remember the distinct RNA virus differences.
