Los cambios ecológicos influyen fuertemente en los patrones de enfermedad. En la presente centuria, inestabilidad climática y el calentamiento progresivo están desempeñando un papel creciente emergencia nuevas enfermedades infecciosas, así como reaparición redistribución olvidadas infecciones. El objetivo del trabajo es analizar contrastar interrelación clima, lluvias temperatura, con l...

In this paper, we describe the dynamics of a vector-borne relapsing disease, such as tick-borne relapsing fever, using the methods of compartmental models. After some motivation and model description we provide a proof of a conjectured general form of the reproductive ratio R0, which is the average number of new infections produced by a single infected individual. A disease free equilibrium und...
