The causes of infection. Diseases can be classified as genetic‚ metabolic‚ or infectious. Infectious diseases are caused by bacteria‚ viruses‚ fungi and parasites that use our body as a host for reproduction and cause illness. Bacteria‚ viruses‚ fungi and parasites. These are all microorganisms which cause infection‚ yet they are all different in structure‚ required environment and conditions needed to thrive and multiply. Bacteria is a single celled organism. It’s shape and size can vary

Causes and spread of infection 1.1: Bacteria are single-celled microorganisms with a simple cellular organization whose nucleus lacks a membrane. Viruses are DNA wrapped in a thin coat of protein that replicates only within the living hosts. Fungi come in many different varieties and we eat quite a few. Mushrooms are fungi as is the mould that forms the blue or green veins in some types of cheese. Yeast is another type of fungi and is the necessary ingredient to make most types of bread.

Although computer viruses and biological viruses are not related in any way‚ they are very similar in many aspects. Both viruses need a host to replicate for a means of survival. Similarly‚ both enter their hosts passively. Biological hosts are infected by breathing‚ ingestion‚ or direct contact while infected software‚ email attachments and transfers infect the cyber host. Another notable similarity is the fact that both computer and biological viruses need the proper host as well as software and

acute diarrheal infection due to water or food ingested contaminated with bacterium Vibrio Cholerae. Cholera infects an estimated 3-5 million persons every year and causes about 100‚000-120‚000 deaths. There is a short incubation period of two hours to five days‚ which greatly enhances the potential of cholera’s dangerous outbreak pattern. About seventy-five percent of cases do not have any symptoms‚ even though the bacteria are present in their feces for 7-14 days post infection and are shed back
