to somehow align. The host‚ pathogen‚ and environment/vector all have to interact at the same time. The vector-borne disease triangle illustrates that without one corner‚ the transmission of the disease would not be possible. This triangle includes hosts‚ environments/vectors‚ and pathogens. Hosts are often humans‚ dogs‚ or monkeys and are fed on by a vector. Vectors usually include mosquitos‚ fleas‚ ticks‚ mites‚ and many more. The last part of the triangle is pathogens‚ these consist of viruses‚

Pathogens have evolved and have various ways to transmit from one host to another. Transmission from one host to another is one way how microbes are able to survive in a long run and maintain their species survivability. If pathogens were not able to transmit‚ upon the death of the host‚ the microbes would not have any means to infect another host. Some pathogens have only one mean of transmitting whereas there are other pathogens that can be transmitted via many different methods. In general‚ there
