Of the 145 cases reported nationally, 113 are in Indiana, 30 in Ohio, one in Hawaii and one in Illinois.

Children appear to be most susceptible to the virus and account for the vast majority of cases. So far, the cases have been generally mild, with most patients exhibiting symptoms similar to seasonal flu and usually recovering on their own.

Two patients required hospitalization, but have since been discharged. There have been no deaths reported in connection with this particular outbreak which began in July.
