Your Health: 1-15-13 Length of a cough

So, how long does the average hacking cough really last?

Experts say many people have a mistaken idea of how long an acute cough should last.

A new study finds this misconception can lead to the unnecessary overuse of antibiotics.

A team of University of Georgia researchers reviewed medical literature and found that the average duration of an acute cough is nearly three weeks. That is 17.8 days.
