Pertusis is a disease caused by a bacterium that causes severe pneumonia resulting in a severe cough that is difficult to control. It is characterized by a shrieking sound that accompanies the patient's attempt to breathe. This disease can be very serious in children under one year old. . Immunodeficiency is weakened over time and adolescents and adults are a major source of infection for children who have not received the vaccine. Since the natural immunity inherited from the mother is weak it is recommended to vaccinate babies against pertussis as soon as possible. A special vaccine for adults and adolescents has been developed against pertussis and is now available and is expected to contribute to curbing the spread of the disease.
