What is the incubation period for rotavirus?

The time period from initial infection to symptoms (incubation period) for rotavirus disease is typically around two days, but varies from one to three days.

What are rotavirus infection symptoms and signs?

Symptoms of the disease include fever, vomiting, and watery diarrhea. Abdominal pain may also occur, and infected children may have profuse watery diarrhea up to several times per day. Symptoms generally persist for three to nine days. Immunity from repeated infection is incomplete after a rotavirus infection, but repeated infections tend to be less severe than the original infection.

Rotavirus infection can be associated with severe dehydration in infants and children. Severe dehydration can lead to death in rare cases, so it is important to recognize and treat this complication of rotavirus infection. In addition to the symptoms of rotavirus infection discussed above, parents should be aware of the symptoms of dehydration that can occur with rotavirus infection or with other serious conditions.

Symptoms of dehydration include

  • lethargy,
  • dry, cool skin,
  • absence of tears when crying,
  • dry or sticky mouth,
  • sunken eyes or sunken fontanel (the soft spot on the head of infants), and
  • extreme thirst.
