Murine typhus as the leading cause of non-focalized fever in the Canary Islands

The high incidence of MT found in both urban and peri-urban areas is particularly noteworthy. Its potential connection with climate change and/or the growth of the reservoir population in the Canary Islands remains unknown. MT's similarity to QF in terms of clinical signs and treatment, coupled with the absence of a specific protocol for early diagnosis, may have contributed to its underdiagnosis. MT can lead to significant health concerns, including risk of hospitalization, complications, and even death. Therefore, the registration of cases for epidemiological control is deemed essential.
