TUCSON, Ariz. (AP) — Health officials say cases of the potentially life-threatening respiratory syncytial virus have risen 40 percent in Arizona this season when compared to the same period a year earlier.
The Arizona Daily Star reports (http://bit.ly/UlYWlK) that 70 cases have been reported statewide as of Nov. 24 and that the majority of cases were reported in Maricopa, Navajo and Pinal counties.
Health officials say it's difficult to say at this point whether this season will be any different from others.
The virus typically peaks in February.
Most of the cases are in children under the age of 5.
While most children are infected with the virus by their second birthdays, only a small percentage develops severe disease.
