Pertussis (whooping cough) is highly contagious, and respiratory isolation is recommended to prevent its spread. When treated with antibiotics like erythromycin, the contagious period is significantly reduced. The standard recommendation is to enforce respiratory isolation for 5 days after the initiation of effective antibiotic treatment. This helps to limit the spread of the infection to others.
