> Virus
> Animals, including humans are affected by it

7

Name the pathogen that causes Tobacco mosaic virus (TMV) and who's affected by it

> Virus
> Plants are affected by it

8

11

Name the pathogen that causes Potato/ Tomato late blight and who's affected by it

> Protoctist
> Potatoes/ Tomatoes are affected by it

12

Name the pathogen that causes Malaria and who's affected by it

> Protoctist
> Animals, including humans are affected by it

13

Examples of directs transmission:

> Droplet infections
> Sexual intercourse
> Physical contact
> Transmission by spores

14

What are spores?

Spores are the cells that some organism use to reproduce asexually, including some protoctist and all fungi

15

What is a direct transmission?

Its when a disease is transmitted directly from one organism to another

16

What is indirect transmission?

Its when a disease is transmitted from one organism to another via an intermediate

17

Examples of indirect transmission

> Air
> Water
> Food
> Vector

18

Which living condition affects transmission of communicable disease?

Overcrowded living conditions increase the transmission of many communicable disease

19

Hows TB spread?

Directly via droplet infection and also indirectly because the bacteria can remain in the air for long period of time and infect new people

20

What social factors affects transmission of communicable disease?

> income
> occupation
> the area where a person lives

21

What happens when theres a limited access to good healthcare?

e.g. People are less likely to be diagnosed and treated for HIV, and the most effective anti-HIV drugs are less likely to be available, so the virus is more likely to be passed on to others

22

What happens when theres a limited access to good health education?

E.G. It would allow to inform people about how HIV is transmitted and how it can be avoided

23

How does climate affect?

> potato/tomato late blight is especially common during wet summers because the spores need water to spread
> Malaria is most common in tropical countries, which are humid and hot. This is because these are the ideal conditions for mosquitoes to breed

24

What is a disease?

Its a condition that impairs thebnormal functioning of an organism

25

What is a pathogen?

An organism that causes disease

26

What is a communicable disease?

Its a disease that can spread between organisms
