Rotavirus Gastroenteritis (RGE)
- What is rotavirus?
- What are the symptoms associated with RGE?
Rotavirus causes a spectrum of illness ranging from asymptomatic infection to severe dehydration resulting from vomiting and diarrhea.2Spectrum of Rotavirus SymptomsAsymptomatic
Symptoms typically include watery diarrhea that can persist for 3 to 7 days, vomiting, fever, and abdominal pain.2
- How is rotavirus transmitted?
Rotavirus is transmitted by the fecal-oral route, both through close person-to-person contact and through fomites (inanimate objects).1
- Which serotypes commonly cause RGE?
- What makes the G2 serotype different?
G2 is genetically distinct from other common rotavirus serotypes.8
For example, serotypes G1, G3 and G4 are typically associated with protein P, while G2 is commonly associated with protein P.8
In other words, G2 strains generally do not share either G or P surface proteins with other common rotavirus G serotypes.8
- Can someone be reinfected with rotavirus?
Yes, children can be reinfected with rotavirus several times during their lives. Second infections are most likely to be caused by another G serotype.9
- Are subsequent infections with rotavirus as severe as the first infection?
Subsequent infections are generally less severe than the first infection.9
- What is the incubation period for rotavirus?
Rotavirus has an estimated incubation period of 1 to 2 days, after which the disease can begin abruptly. Fever and vomiting often precede diarrhea.1
