What are the ways that pathogens are spread?
Pathogens are spread through direct contact, water, and air.
What is an example of direct contact transmission?
Examples include kissing, contact with bodily fluids, and microorganisms from faeces.
How can pathogens be spread by water?
Pathogens can be spread by drinking or coming into contact with dirty water.
What is a common example of air transmission of pathogens?
A common example is droplet infection, which occurs when sneezing, coughing, or talking expels pathogens in droplets.
How can the damage caused by disease to populations be reduced?
Damage can be reduced by improving hygiene, reducing contact with infected individuals, removing vectors, and vaccination.
What are some methods to improve hygiene?
Methods include hand washing, using disinfectants, isolating raw meat, and using tissues when sneezing.
What does removing vectors involve?
It involves using pesticides or insecticides and removing their habitat.
What is vaccination?
Vaccination involves injecting a small amount of a harmless pathogen to make an individual immune.
What is the benefit of vaccination?
It prevents infection and reduces the likelihood of passing the pathogen to others.
