Plague is transmitted by all EXCEPT?
**Core Concept**
Plague is a bacterial infection caused by Yersinia pestis, transmitted to humans through the bites of infected fleas, direct contact with infected animals, or inhalation of respiratory droplets from an infected person. The disease manifests in three main forms: bubonic, pneumonic, and septicemic.
**Why the Correct Answer is Right**
Plague transmission primarily occurs through the bites of infected fleas (reservoir: rodents and their fleas), direct contact with infected animals (e.g., handling infected rodents or their tissues), and inhalation of respiratory droplets from an infected person (pneumonic plague). This highlights the importance of vector control, personal protective measures, and early diagnosis in preventing the spread of plague.
