Introduction
Pathogens are organisms that cause diseases. There are three types of organisms responsible for most waterborne disease which includes viruses, bacteria and protozoa. Faecal matter from humans and other animals is the source of water contamination. The intestinal tract is affected by Rotavirus and symptoms include diarrhoea, vomiting, headaches, fevers and chills. Some waterborne diseases can cause death. Along with these pathogens, also come parasites.
The two types of intestinal parasites are helminthes and protozoa. Helminthes are worms with multiple cells. The most common helminthes are tapeworms, pinworms and ringworms. These intestinal parasites may also be transmitted by sexual intercourse and other forms of sexual play. In the helminthes adult form they cannot multiply in the human body. Protozoa have only one cell which multiplies inside the human body which allows for serious infections. Intestinal parasites are usually transmitted when someone comes in contact with infected faeces which are present in contaminated soil, food, or water which is caused by poor hygiene.
This report focuses on a particular pathogen or infectious agent that causes disease or illness to its host. The investigation of the impact that rotavirus has on the human body from a cellular level to the body systems and the discussion of how it has and will impact on society. This investigation will be done by collecting, organizing and analysing relevant past and present scientific data which will then be compiled and presented as an analytical report with research findings and knowledge regarding parasites and pathogens.

Serotype G1 continues to be the most frequently reported serotype worldwide and has been the most common Australian serotype, for all but two years since 1999.

Conclusion
Rotavirus is a common cause of viral gastroenteritis for Australian babies and preschool children. Infection is caused by person-to-person contact such as touching contaminated hands or faeces (poo). It is possible to be infected with rotavirus several times. Rotavirus impacts the human systems in many different ways. It also has biological impacts on society through past, present and future predictions. In conclusion, Rotavirus affects a majority of the world and has a great effect on young children.
