Pathogens in the environment
In many cases, diseases start with pathogens in the environment. Many different living and non-living things can be
pathogens. Bacteria and viruses are examples of pathogens. Many pathogens are carried from one place to another by
insects and animals. These living things are called carriers. Ticks are carriers of Lyme disease. Wearing long sleeves
and using insect spray can reduce your risk of getting Lyme disease.
