Non-vaccinal prophylaxis of tularemia

Area of Science:

• Zoonotic Diseases
• Infectious Disease Epidemiology
• Public Health Microbiology

Background:

• Tularemia is a re-emerging zoonosis caused by the bacterium Francisella tularensis, a significant biological threat agent.
• Infection in humans occurs through various routes (cutaneous, respiratory, etc.) from animal or environmental reservoirs and arthropod vectors.
• The disease can be debilitating and life-threatening, with no available vaccines for humans or animals.

Purpose of the Study:

• To review available individual prophylactic measures against tularemia.
• To discuss underdeveloped possibilities for collective prophylaxis.
• To highlight the need for adapted, One Health approaches to control F. tularensis.

Main Methods:

• Literature review of existing prophylactic measures for tularemia.
• Analysis of risk factors associated with F. tularensis transmission.
• Discussion of current challenges and future directions in tularemia prevention.

Main Results:

• Individual prophylactic measures are available but depend on specific risk factors and transmission routes.
• Collective prophylaxis strategies are underdeveloped.
• Control requires integrated approaches targeting animal and environmental reservoirs and vectors.

Conclusions:

• Non-vaccine prophylaxis for tularemia is complex due to the bacterium's life cycle and diverse infection routes.
• Prophylactic strategies must be tailored to endemic areas and require a One Health approach.
• Controlling reservoirs and vectors is crucial to slow disease expansion, especially with climate change.
