When we talk about the three diseases: Spanish flu, black patch and AIDS, what comes to mind ? Is it the fact that each of them killed millions of people? Or that they each arrived at different times on earth? I would like to compare the agents of each particular disease and the regions of the world that have also been affected by these pandemics. Additionally, I would like to discuss the symptoms, remedies, and potential cures for these illnesses. The Black Death began in the 14th century. Relative to the world's population, it was by far the worst scourge. About a third of the world's inhabitants have died from it. Europe in particular suffered the most, losing sixty percent of its population (Benedictow, 2005). It is believed to have started in Asia and later spread to Europe and Africa. The world knew a lot about this disease by the time it ran its course. It was triggered by a bacteria called Yersinia Pestis (ibid). This germ inhabits fleas which in turn inhabit rodents, notably the black rat. This leads to the impossibility of its total eradication since these pests reproduce rapidly and spread throughout the world. The Black Death could be defined as a zoonotic disease or a particularly dangerous scourge. The pandemic spread very quickly from one country to another by ships carrying infected rats. Historians and scientists are convinced that it was fleas that spread the disease since unlike other epidemics, the infection spread during the summer months when rats could travel (ibid.). Usually, diseases spread more quickly during the summer months. Symptoms of infection include pus-filled boils, headaches, and bleeding under the skin. The most prominent symptoms were buboes, swollen lymph nodes....... middle of paper ...... yes). Pandemics: avoiding the mistakes of 1918. Nature Publishing Group, 324-326.
