Which reservoir has been identified as important in the transmission of pertussis?

Explanation:
Pertussis spreads primarily from person to person through respiratory droplets when someone with the infection coughs or sneezes. The reservoir is the population that maintains and spreads the pathogen, which for Bordetella pertussis is humans. Infected adults can harbor and shed the bacteria, sometimes with mild symptoms, and thus serve as a continuing source of transmission to others, including unvaccinated or vulnerable infants. Mosquitoes, domestic pets, and white-tailed deer do not serve as reservoirs for this human-specific pathogen, so they’re not considered important in its transmission.
