> Bacterium
> Humans are affected by it
Name the pathogen that causes Ring Rot and who’s affected by it
> Bacterium
> Potatoes, Tomatoes are affected by it
Name the pathogen that causes HIV/AIDS and who’s affected by it
> Virus
> Humans are affected by it
Name the pathogen that causes Influenza and who’s affected by it
> Virus
> Animals, including humans are affected by it
Name the pathogen that causes Tobacco mosaic virus (TMV) and who’s affected by it
> Virus
> Plants are affected by it

Examples of directs transmission:
> Droplet infections
Sexual intercourse
Physical contact
Transmission by spores
What are spores?
Spores are the cells that some organism use to reproduce asexually, including some protoctist and all fungi
What is a direct transmission?
Its when a disease is transmitted directly from one organism to another
What is indirect transmission?
Its when a disease is transmitted from one organism to another via an intermediate
Examples of indirect transmission
> Air
Water
Food
Vector
Which living condition affects transmission of communicable disease?
Overcrowded living conditions increase the transmission of many communicable disease
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
What social factors affects transmission of communicable disease?
> income
occupation
the area where a person lives
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
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
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
What is a disease?
Its a condition that impairs thebnormal functioning of an organism
What is a pathogen?
An organism that causes disease
What is a communicable disease?
Its a disease that can spread between organisms
