Pertussis, a symptom caused by the infection of Corynebacterium diphtheriae or Bordetella pertussis, facilitates the presence of these substantive pathogens in the body. These pathogens stimulate the body's temperature regulation center, leading to immune fever symptoms. This is a reaction where the body's resistance is fighting against these pathogens, causing a rise in body temperature which is considered normal. During the acute phase, symptomatic treatment should be administered. At the same time, based on the type of infectious pathogen, a sensitive antimicrobial agent should be chosen for etiological treatment. Additionally, it's important to drink plenty of fluids and maintain clean indoor air.
