WebDifferent pathogens can be spread by different mechanisms, for example malaria is transmitted by mosquitoes, cholera is transmitted via water and HIV is transmitted via bodily fluids. Most viruses are much smaller than bacteria and not only do they enter cells in the body, they reproduce inside cells hundreds of thousands of times. WebMar 16, 2024 · Copy Link to Article. Viruses survive outside our bodies because of how they are built. Specifically, they are pieces of genetic material (RNA or DNA) contained in a special coating of proteins called capsids. Viruses cannot replicate unless absorbed by cells in our body. Once a virus is outside the body, its capsid starts to degrade, and the ...
