Mycoplasma infection cough is a prominent symptom characterized by an incubation period. Dry cough appears two to three days later, followed by episodes of coughing. Cough may be accompanied by a small amount of mucus, or viscous secretions, sometimes with streaks of blood. The cough generally lasts for a long time, persisting for one to two weeks, and if not well managed, it can continue for about a month. Severe cough can be treated symptomatically with asthma-relieving and cough-suppressing medications.
