Pathogens And Disease Transmission
Overzicht
An outbreak of cholera in a city with poor sanitation, an athlete picking up a fungal infection in a shared changing room, and malaria spreading through a region with stagnant water all look like unrelated problems, but each follows directly from the biology of the organism responsible and the route it uses to reach a new host.
This lesson covers how infectious disease develops in a person, the structure and biology of viruses and bacteria, and the specific transmission, treatment and prevention of seven named diseases: Ebola, HIV, cholera, gonorrhoea, athlete's foot, malaria and typhoid, including the roles of the mosquito and housefly as disease vectors.
Doelstellingen

- Describe methods of transmission, treatment and prevention of the spread of Ebola and HIV (human immuno-deficiency virus), the virus that causes AIDS
- Describe the structure, nutrition and reproduction of bacteria including the interpretation of bacterial growth curves
- Investigate the effects of antibacterial agents and antibiotics on the growth of bacterial culture
- Know the methods of transmission, treatment and prevention of the spread of cholera and gonorrhoea
- Explain the importance of oral rehydration therapy
- Know the methods of transmission, treatment and prevention of the spread of athlete's foot
- Explain the role of the mosquito (malaria) and housefly (typhoid) in transmitting causative agents of disease
- Describe the treatment and prevention of the spread of malaria and typhoid
