Pertussis has many symptoms. The early symptoms are the same as those of a common cold, including a runny nose, sore throat, and fever. About one to two weeks later, episodic, spastic coughing occurs. Some may also experience a barking cough and a crowing sound during inhalation, which are characteristic symptoms of pertussis. This type of cough can lead to complications such as an acute facial expression, redness in the face and ears, runny nose, tears, and vomiting. It is necessary to culture the pathogen and choose sensitive antibiotics to kill this bordetella pertussis.
