Illness begins most frequently with fever, runny nose, cough, and sometimes wheezing.
Rotavirus is the most common cause of severe diarrhea among children. Transmission can occur through ingestion of contaminated water or food and contact with contaminated surfaces. The disease is characterized by vomiting and watery diarrhea, with fever and abdominal pain frequently occurring. HPIVs are spread from respiratory secretions through close contact with infected persons or contact with contaminated surfaces or objects. All adenoviruses are transmitted by direct contact, fecal-oral transmission, and occasionally waterborne transmission.
