Final answer:
B. pertussis infections can be treated with erythromycin or tetracycline antibiotics, but vaccination is a better approach to control the disease.
Step-by-step explanation:
B. pertussis infections can be treated with antibiotics such as erythromycin or tetracycline, but they are most effective when given at the very earliest stages of the disease. These antibiotics can reduce the rate of transmission when given later in the infection or as a preventive measure to uninfected individuals. However, active vaccination, such as the DTaP and Tdap vaccines that contain a pertussis toxoid, is a better approach to control pertussis.
