Rotavirus Symptoms in Children: Causes, Diagnosis & Treatment

Rotovirus, also known as rotavirus, is one of the leading causes of extreme diarrhea in young children and infants. This virus has five different species, A through E. By age 5, most children have been infected with at least one strain. Many older children or adults who have a rotavirus infection show no symptoms because the immune system has controlled the condition, and the infection is gone within a few days.

Diarrhea

• A rotavirus infection typically is associated with infant diarrhea that is frequent and watery. The condition can be treated with water and electrolytes until the diarrhea ceases. The child should see a doctor if the diarrhea becomes severe or bloody. Adults typically will not have as severe diarrhea, but they may have blood in their stool.

Nausea and Vomiting

• Rotavirus infections often are accompanied by nausea and vomiting. You should see a doctor if the vomit contains blood or if the vomiting is frequent over the course of three hours. The nausea also may involve abdominal cramps.

Dehydration and Fatigue

• A rotavirus infection can include dehydration and fatigue symptoms, including lethargy, restlessness, thirst, irritability, crying without tears, dry mouth and tongue, infrequent urination, a dry diaper for several hours (in infants) and sunken eyes. If these symptoms are consistent, hydrate the child and contact a doctor.

Cold-like Symptoms

• There are several rotavirus symptoms that resemble the signs of a cold. These can include coughing, runny nose and a fever. Contact a doctor if a child's fever nears 102 degrees F or 104 degrees F for an adult.
