Broad patterns in domestic vector-borne Trypanosoma cruzi transmission dynamics: synanthropic animals and vector control

Trypanosoma Cruzi and Domestic Animals

Chagas disease is one of the most important zoonosis affecting the Latin America. Despite important progress achieved in last decades through strategies at regional level against vectoral transmission and improvement of screening among blood donors, the disease continues to represent a public health priority. Knowledge on epidemiology of the etiological agent Tripanosoma cruzi is of outmost imp...

Control and Management of Vector-Borne Diseases in Disaster Conditions

Disasters are a set of unexpected situations that occur as a result of natural misadventure or human manipulations. Depending on the type, time, and location of the events, the insect population causing vector-borne diseases is affected, which may eventually lead to widespread epidemics. Parasitic diseases such as malaria, leishmaniosis, arboviral diseases such as dengue fever, West Nile enceph...

Transmission dynamics for vector-borne diseases in a patchy environment.

In this paper, a mathematical model is derived to describe the transmission and spread of vector-borne diseases over a patchy environment. The model incorporates into the classic Ross-MacDonald model two factors: disease latencies in both hosts and vectors, and dispersal of hosts between patches. The basic reproduction number R(0) is identified by the theory of the next generation operator for ...

Trypanosoma cruzi - the vector-parasite paradox.

Trypanosoma cruzi and the majority of its insect vectors (Hemiptera, Reduviidae, Triatominae) are confined to the Americas. But while recent molecular studies indicate a relatively ancient origin for the parasite ( approximately 65 million years ago) there is increasing evidence that the blood-sucking triatomine vectors have evolved comparatively recently (<5 mya). This review examines the evid...
