What causes common disease symptoms?
Common symptoms of diseases are caused by your body responding to and trying to prevent the spread of the pathogens.
How are pathogens spread by air?
Tiny droplets full of pathogens are expelled, which can be breathed in and cause an infection.
How can pathogens be spread by water?
Pathogens in water can be spread through the digestive system, or in the case of plants fungal spores can be carried to plants.
How can pathogens be spread by direct contact?
Common in plant diseases, direct contact with infected hosts or contact with blood can pass on the pathogens.
