Gender Ethnicracial And Life Span Considerations

Children under age 2 are more susceptible to infectious gastroenteritis because their immune system is not yet fully developed. Rotavirus gastroenteritis is usually confined to infants and children under 3 years of age. By age 3, most children develop antibodies against the rotaviruses. Both men and women with low levels of antibody can be infected, particularly family members of affected infants. Severe, prolonged diarrhea may be fatal in elderly persons and infants when severe fluid and electrolyte imbalance occurs. Infants become dehydrated very rapidly. The worldwide incidence is uncertain, and no ethnic and racial consideratins are known; wide variations exist in global estimates of mortality and morbidity.
