Doctors at the Medical University of South Carolina are reporting an uptick in walking pneumonia cases. Walking pneumonia, a mild version of pneumonia, is a slow-developing lung infection that causes cold-like symptoms but often allows people to continue their daily activities despite generally feeling unwell.

The bacterial infection's numbers have been rising nationally and in Ohio since the late spring and early summer months.

In October, the CDC wrote that since late spring, the number of infections caused by walking pneumonia has been increasing, especially among young children.
