What you need to know:

Nine children have died from complications associated with adenovirus in a Haskell, New Jersey healthcare facility over the last week.  Adenovirus causes symptoms similar to influenza, including mild malaise, runny/stuffy nose, pharyngitis, and conjunctivitis. Diarrhea may also occur in children. Adenovirus is usually either clinically insignificant or self-limited and primarily affects military recruits, young children, and infants. When people with compromised immune systems develop adenovirus, there may be serious morbidity and mortality issues, as with the children who died in New Jersey over the last several days.

Adenovirus may be confused with influenza, so it is important to recognize differences in clinical symptoms, transmission modes, and associated incubation periods, as well as diagnostic tests, treatments, and preventive vaccines that are available.
