Two cases of tularemia in hunters from rural Newfoundland.

Background: Tularemia is a rare zoonosis caused by a small gram-negative intracellular coccobacillus. Transmission occurs through direct contact with small mammals such as hares and rabbits, exposure to ticks, or ingestion or inhalation of aerosolized particles. It is a highly variable disease with six subtypes based on clinical features. Tularemia is a very rare disease in Canada, with only 0.01 cases per 100,000 people reported in 2017.

Methods: In this case report, we describe two cases of tularemia affecting hunters from rural Newfoundland and Labrador.

Results: The first case describes a patient with glandular tularemia diagnosed with serology; the second describes a patient with typhoidal tularemia diagnosed on blood culture. Both patients recovered after treatment with gentamicin.

Discussion: These cases highlight the importance of eliciting a careful social history from patients presenting with an unexplained febrile illness. Tularemia should be considered in the differential diagnosis of fever after hunting in rural areas.
