Hundreds of children across the United States have been hospitalized after contracting a respiratory virus, medical information.
The culprit is believed to be the EV-D68 enterovirus, which causes cold-like symptoms.
Ten states in the Midwest, from Colorado to North Carolina, have reported cases in the past month.
Dozens of children have been admitted to intensive care.
Experts believe that the number of cases is likely to increase.
Enteroviruses are common pathogens and often do not require hospitalization. Symptoms typically manifest as a bad cold, and the number of infections decreases in September.
But last month, several hospitals reported an unusually high number of cases in which cold symptoms were complicated by acute respiratory problems and in which the patient required hospitalization and, in some cases, intensive therapy.
