The rapid increase in the incidence of diseases transmitted by vectors, with worldwide spread, is the major cause of problems whose main determinants are political factors, economic, environmental and human behavior.

Human actions are the cause of  radical changes at the level of interactions between different components of Ecosfera, which causes the transmission of human infectious diseases.When the cycle of transmission includes mosquitoes, ticks, rodents and other intermediaries, ecology and their behavior have an important role.

As more species are involved, the level of complexity is becoming higher. Subsequently, the virulence of pathogens, the susceptibility of its vectors and hosts, host immunity and collective immunity of host populations,  contribute to the force of transmission.

The role of rodents in transmission of a large number of bacterial diseases, virus and parasitic diseases, both in humans and animals is well known. Mice, especially rats, are reservoirs of infection, especially vectors, spreading Trichinellosis, leptospirosis, brucellosis, anthrax, rabies, infectious gastroenteritis, etc.

Also, insects are the agents of transmission to humans and animals, of infectious and parasitic diseases.
Species of insects, vector transmission type, are:
fly, mosquito, bug house, cockroach,human flea ,home spider , moth clothes , etc.

Diseases spread of these : tuberculosis, plague, malaria, typhus, lumpy, food poisoning, skin infections, etc..
