How can Tularemia be contracted by humans?

• A. By eating contaminated fish
• B. By handling raw infected meats
• C. By drinking contaminated water
• D. By exposure to mosquito bites

Answer: (B)

Tularemia, caused by the bacterium Francisella tularensis, is primarily transmitted to humans through direct contact with infected animals or their tissues. Handling raw infected meats, particularly from animals such as rabbits, hares, or even some rodents, is a significant route of transmission. When individuals come into contact with the blood or other bodily fluids of these animals, they can become infected, especially if there are cuts or abrasions on the skin. The other options, while they may involve exposure to pathogens or contaminants, are less relevant for tularemia specifically. For instance, eating contaminated fish is more associated with different infections such as those caused by parasites or bacteria prevalent in aquatic environments. Drinking contaminated water can lead to various waterborne illnesses, but tularemia is not typically transmitted this way. Exposure to mosquito bites is not a transmission route for tularemia, as the bacteria is not associated with insect vectors in the same manner as diseases like West Nile virus or Zika virus. Therefore, handling raw infected meats stands out as the main and most direct method by which humans can contract tularemia.
