Decent Essays

This essay will be covering different epidemics such as Spanish Flu, small pox and Ebola. I will also, be looking at what research and practises are being done around immunisation and controlling future epidemics and why this is crucial for the human population. However, first I’ll discuss how the immune system works, the immune response involves “two complementary systems, the humoral and cellular systems”. (David L. Nelson and Michael M. Cox, 2013, p. 174) The humoral immune system is aimed at “bacterial infections and extracellular viruses” ”.( David L. Nelson and Michael M. Cox, 2013, p. 174) whereas, the cellular systems involves macrophages, T cells and B cells. When a cell gets infected it becomes an antigen presenting cell which is detected by a macrophage, this triggers clonal expansion of complementary T killer and T helper cells. Whilst the T killer cells destroy the infected cells, T helper produce cytokines which trigger clonal selection and expansion of complementary B cells. B cells then divide into memory cells and plasma cells …show more content…

At first the Spanish flu was considered a mild disease as there were no deaths from it however over time the virus had spread to other countries such as India and China, “suddenly 8 million people were down with the bug.” (People and Discoveries, para 1) As the seasons changed in 1918, “the epidemic lost its mildness: people started to die.” (People and Discoveries, para 1) An estimate of 57,000 American soldiers died from influenza that year and around 53,000 died in battle, showing how the epidemic has effected the population numbers more in a short amount of space than a war which went on for 4 years. However due to war and peace being given most of the attention at the time “still little is known about the origin or nature of the killer virus.” (People and Discoveries, para
