1
Q

what do vaccinations do

A

expose the immune system to a non infectious source of parasite antigens to allow the body to develop immunological memory

2
Q

what are the three difficulties in developing effective treatments

A

host parasite interconnection , rapid evolution, difficult to culture away from hosts

3
Q

what is targeted in alternative ways to control parasites

A

the transmission stage of the parasites lifecycle

4
Q

what are two alternative ways to control parasites

A

civil engineering projects and vector control

5
Q

describe how civil engineering projects control parasites

A

work to improve sanitation, for example prevent mixing of clean and dirty water, helps in cases of chlorea and shcistosoma

6
Q

what type of parasites are targeted with nets and insecticides as a method of vector control

A

mosquito carried viruses

7
Q

what two factors can make parasite control difficult

A

overcrowding and tropical climates

8
Q

how can overcrowding make parasite control more difficult

A

hosts are close together, poor sanitation and parasites can spread rapidly

9
Q

how can tropical climates affect vector control

A

make it harder, parasites can survive away from hosts and reproduce rapidly

10
Q

what are the three benefits of improved parasite control

A

more resources for growth and development, improvements in child development/intelligence and reduction in child mortality
