Pertussis is a highly contagious disease rare in developed countries, thanks to years of preventive vaccination. Bordetella pertussis, also known as bacillus Bordet-Gengou, is responsible for whooping cough. The contagion spreads through the respiratory tract and occurs mainly at the beginning of the disease during the period defined by non-specific symptoms like dry cough, sneezing, rhinitis, and mild fever. Pertussis is characterized by an excess of coughing occurring in fits followed by labored breathing. The child is exhausted after coughing. The isolation of the patient is necessary to stem the contamination.
