This indicates that infected humans rather than reservoir hosts play a major role in the epidemiology of the disease.
It may be that they function as intermediary reservoir hosts, the virus being transmitted to mammals by ticks or other arthropods.
Those studies established a link between habitats favourable to reservoir hosts, habitat resource quality for a particular species, and transmission.
The human and animal reservoir hosts acquire the infection from the ingestion of raw, inadequately cooked freshwater fish.
Consequently, these cervids have been considered as important reservoir hosts.
However, reservoir hosts such as monkeys are known to catch and eat both adults and naiads.
As a result, ticks are not only vectors but also excellent reservoir hosts for the viruses they carry.
The occurrence of reservoir hosts has obvious implications for the epidemiology of human infections, and for the success of control programmes.
These results are discussed in relation to the importance of wild rodents as reservoir hosts and sources of infection for local human communities.
Neither habitat is closely associated with human habitation although the latter may provide a suitable environment for rodent reservoir hosts (see below).
