Pertussis, also known as whooping cough, is a contagious disease that is a respiratory tract infection. It primarily spreads through airborne droplets and close daily contact. Clinically, there is a vaccine available for this condition, mainly the DTP (diphtheria, tetanus, and pertussis) vaccine. Following the vaccination schedule and developing antibodies can effectively prevent the disease. This disease has a lengthy course and can easily cause recurrent coughing episodes and persistent symptoms. It is important to correctly understand and be aware of the characteristics of its onset. If suspected, early examination and timely selection of medications for symptom control are essential, along with addressing the underlying cause.
