How is tularemia primarily transmitted?

• A. Through contaminated water
• B. Via ticks
• C. By direct contact with infected hosts
• D. Through airborne spores

Answer: (B)

Tularemia is primarily transmitted via ticks, which are known vectors for the bacterium Francisella tularensis, the causative agent of the disease. When a tick that carries the bacteria bites a human, it can transmit the infection through its saliva. This mode of transmission is particularly significant in regions where ticks are prevalent, making it a critical pathway for spreading tularemia. While other methods of transmission exist, they are less common or less significant compared to tick bites. For example, contaminated water can pose a risk, but it is not the primary route for tularemia transmission. Direct contact with infected hosts, which can include handling infected animals, is another route of transmission but is less frequently encountered than tick bites. Airborne spores are not a typical transmission pathway for tularemia, further reinforcing the importance of ticks as the main vector in spreading the disease. Understanding these transmission routes is crucial for implementing effective prevention strategies against tularemia.
