Transmission Parameters of Vector-Borne Infections

Médecine Et Maladies Infectieuses, 2011
Vector-borne infections are those for which the agent (virus, bacteria, or parasite) is transmitted from an infected host (animal or human) to another by a hematophagous arthropod (mosquito, tick, lice, and flea). Two parameters quantify the dynamics of a vector-borne infection: (1) the basic reproductive number (R(0)) that is the mean number of ...

Emerging Vector-Borne Infections

Infectious Disease Clinics of North America, 1991
The principles that regulate the transmission of vector-borne infectious agents are briefly described. In particular, the circumstances that may lead to human exposure to various North American zoonoses are analyzed.

Asymptotic Analysis of a Vector-Borne Disease Model With the Age of Infection [PDF]

Journal of Biological Dynamics, 2020
Vector-borne infectious diseases may involve both horizontal transmission between hosts and transmission from infected vectors to susceptible hosts. In this paper, we incorporate these two transmission modes into a vector-borne disease model that includes general nonlinear incidence rates and the age of infection for both hosts and vectors. We show the

Therapy of vector-borne protozoan infections in nonendemic settings

Expert Review of Anti-infective Therapy, 2011
Vector-borne protozoan infections are responsible for a wide variety of illnesses (mainly malaria, trypanosomiasis and leishmaniasis) affecting tropical and subtropical areas, but increasingly diagnosed in nonendemic settings. This article summarizes the therapeutic developments for these conditions during the past decade and focuses specifically on ...

Modeling the impact of global warming on vector-borne infections

Physics of Life Reviews, 2011
Global warming will certainly affect the abundance and distribution of disease vectors. The effect of global warming, however, depends on the complex interaction between the human host population and the causative infectious agent. In this work we review some mathematical models that were proposed to study the impact of the increase in ambient ...

Host Spatial Heterogeneity and the Spread of Vector-Borne Infection

Theoretical Population Biology, 2001
We analyze how spatial heterogeneity in host density affects the advance of vector-borne disease. Infection requires vector infestation. The vector spreads only between hosts occupying the same neighborhood, and the number of hosts varies randomly among neighborhoods.

Travel-related vector-borne virus infections in Germany

1996
Laboratory diagnosis of imported, vector-borne virus diseases during a 22-month-period in Munich, Germany, is summarized. IN 13/317 Germans returning from the Mediterranean with suspected sandfly fever, acute sandfly fever, serotype Toscana, was confirmed serologically: 84.6% of the infections were acquired in Italy. Of 249 German tourists with febrile

The Role of Nutrition in Virus Dynamics in Vector-Borne Viral Infections

Journal of Theoretical Biology
Malnutrition alters metabolism and immunity, affecting one's ability to fight infections and influencing clinical outcomes. To quantify differences in infection dynamics among groups of different nutrition statuses and challenged with different viruses, we developed within-host mathematical models of acute infections and fitted them to data from mice ...
