Athelete's foot - 8Give examples of diseases caused by protoctistsMalaria
Potato/tomato late blight - 9What are the two types of transmission (of diseases)?Direct
Indirect - 10What is direct transmission?A disease that is transmitted directly from one organism to another:
Droplet infection (coughing/sneezing)
Sexual intercourse
Touching an infected organism - 11Give examples of direct transmission of diseasesHIV = sexual intercourse or mother to child through placenta
Athlete's foot = touch - 12What is indirect transmission?A disease is transmitted from one organism to another via an intermediate (including air, food or a vector)
- 13Give examples of indirect transmission of diseasesPotato/tomato late blight = spores (carried through air, then water)
Malaria = mosquitoes act as vectors - 14What are the factors affecting transmission?Living conditions
Social factors
Climate - 15How do living conditions affect the rate of transmission?Overcrowded living conditions increase transmission
E.g. TB = droplet infection; risk of infection is increased when lots of people are crowded - 16How do social factors affect the rate of transmission?Income, occupation and environment
Healthcare - likeliness to be diagnosed and treated as well as availability of drugs
Health education - inform people of transmission (e.g. HIV - using condoms) - 17How does climate affect the rate of transmission?E.g. potato/tomato late blight - common during wet summers (spores need water to spread)
E.g. malaria - common in tropical countries (humid and hot); ideal conditions to breed
