What causes rotavirus infection?
The rotavirus is a member of the Reoviridae family of viruses and contains double-stranded RNA enclosed by a double-shelled outer layer (capsid). Infection with different strains of the virus is possible, so it is common to have several separate rotavirus infections in childhood. Adults may also become infected, but the resulting illness is usually less severe than that in infants and young children.
What are risk factors for rotavirus infection?
Infants and children are most commonly infected with rotavirus. Since rotavirus infection is highly contagious, those who are around infected people are at high risk of infection. For this reason, children in group day-care settings are at risk. However, most children will become infected with rotavirus by 3 years of age.
What are rotavirus symptoms and signs?
The time period from initial infection to symptoms (incubation period) for rotavirus disease is around two days. 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),
- extreme thirst.
