“…The value of these predictions will depend upon the biologies of specific systems so cannot explain broad patterns, but may well hold for many systems. Thus, while vertical transmission may occur in vectors of vertebrate diseases (Burgdorfer and Brinton 1975, Fine 1975, Aitken et al 1979, it is not the rule and is actually more common in plants than in their vectors (Power 1992, Nault 1997.…”

How Virulent Should a Parasite Be to Its Vector?

Abstract. Vector-borne parasites are commonly predicted to be less virulent to the vector than to the definitive host as the parasite gains little by harming its main route of transmission. Here we assess the empirical evidence from systems in which insects are vectors for vertebrate, plant, and invertebrate parasites. The body of evidence supports lower (but nonzero) parasite virulence to vectors than to plant or invertebrate hosts, but not to vertebrate hosts. We consider why this might be by assessing evolutionarily stable strategies for an insect parasite that can infect both predator and prey (or vector and definitive host) and can have distinct virulences in these two potential hosts. In a homogeneous environment, the parasite is predicted to be equally virulent to predator and prey. However, in a patchy environment it is predicted to become benign toward the more mobile of the two potential hosts, provided interpatch movement of free parasites is low and competitive displacement among strains in a patch is weak. This prediction meets reality in that the vector is usually more mobile between patches than is the definitive host in plant and invertebrate systems, but not necessarily in vertebrate hosts.

“…In the sylvatic cycle, mosquitoes, like Aedes africanus (in Africa) or Haemagogus species (in the Americas) act as the leading vectors and monkeys as the principal (primary) host. In the mosquito population, the vertical transmission has been also found and may have played a vital role in sustaining the sylvatic cycle (Figure 2) [26,27]. Sometimes infected mosquitoes bite unvaccinated forest workers e.g.…”

Yellow fever virus (YFV) is belonging to flaviviridae family which was identified as the causative agent of Yellow fever (YF), acute viral hemorrhagic disease which was first time notified by International health regulation (IHR), globally. Initially YF considered to partial control for decades but now increasing globally with the risk of local epidemic outbreaks. This review represents the occurrence of YF diseases in the 21 th century and the remotely sensed satellite data are used to define climatic limits within a discriminant analytical model frame work. The study also shows the potentially co-occurrence and global epidemiology of risk maps for this disease in Africa and South East Asia in the framework of the ecological and historical forces. The aim of this study is to portray attention to this rising epidemic and to provide force for the necessary public health response.
