This disease is called whooping cough mainly because the disease itself has a long course, which led to its name. If not treated in time, some patients may take two to three months to recover. If detected and treated early, generally complete recovery is possible within about 10-20 days. The main symptoms are paroxysmal, spasmodic coughing, some may also exhibit a barking cough, or a crowing inspiration sound, among other typical manifestations.
