Hantavirus & Relapsing Fever

Hantavirus pulmonary syndrome has a concerning case fatality rate of 30-50% and is primarily transmitted through aerosolized mouse droppings, with rare instances of person-to-person transmission noted. In contrast, relapsing fever, caused by Borrelia species, can be transmitted through louse bites or tick bites, with potential for person-to-person transmission in louse-borne cases. The discussion highlights the distinct epidemiological characteristics and transmission methods of these two diseases.
