13
Q

Examples of directs transmission:

A

> Droplet infections
Sexual intercourse
Physical contact
Transmission by spores

14
Q

What are spores?

A

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

15
Q

What is a direct transmission?

A

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

16
Q

What is indirect transmission?

A

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

17
Q

Examples of indirect transmission

A

> Air
Water
Food
Vector

18
Q

Which living condition affects transmission of communicable disease?

A

Overcrowded living conditions increase the transmission of many communicable disease

19
Q

Hows TB spread?

A

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

the area where a person lives

21
Q

What happens when theres a limited access to good healthcare?

A

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
Q

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

A

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

23
Q

How does climate affect?

A

> 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
