Smallpox is a disease that was successfully eradicated in 1980 after vaccinations were given. It is a contagious disease caused by the variola virus that was spread though all three types of contact transmission, direct, indirect and droplet transmission meaning that it was easily spread throughout communities through contact with infected individuals, bodily fluids or items that have been contaminated (National Geographic, 2017). Once a person becomes infected it can take up to 17 days for them to become symptomatic and during this incubation period they are not contagious (Department of Health, 2017).
Further, this disease came in two forms, variola major and variola minor. The most commonly occurring form, variola major was deadly whereas …show more content…
For instance, at the time smallpox was spreading infected individuals were not isolated as this was before Germ theory was formulated. This meant that infected people would unknowingly spread the disease to other people and potentially other communities. Also, because the people living in the Americas were so isolated from Europe they did not have a great deal of immunity from European diseases. Therefore, a large number of people got sick as they weren’t immune which spread the disease further throughout the Americas (Yahoo, 2011). Further, there wasn’t a high hygiene standard, Malaria
Malaria is a disease that is spread through biological vector transmission. Female mosquitoes become infected through biting an infected person. Also, infected female mosquitos carry the parasite within their saliva and this is transferred into the wound the mosquito makes on the body when they feed. Additionally, the mosquito’s saliva also contains chemicals that prevent the blood from clotting and a minor pain relief (Malaria, 2017). Furthermore, malaria can also be spread through vehicle transmission such as through blood transfusions and organ transplants or through indirect contract transmission by touching contaminated needles or syringes (CDC, 2017c).
In addition, factors that influence the spread of malaria include temperature as this can affect the parasite’s life cycle and the speed at which mosquitoes develop
