10 Histoplasmosis Symptoms
Symptom #5: Dry Cough
Cough refers to the repetitive and sudden protective reflex which functions to clear the airways from microbes, foreign particles, fluids, and irritants. There are three phases to the cough reflex: inhalation, forced exhalation, and release of air from lungs which makes a distinctive sound. When there is frequent coughing, it may indicate the presence of a disease.
From an evolutionary perspective, coughing is beneficial to bacteria and viruses as it helps to spread the disease to new hosts. Causes of coughing include air pollution, choking, asthma, smoking, post nasal drip, heart failure, and lung tumors. In histoplasmosis, the cough is often dry.
