There are many methods of pathogen eradication. Methods include: harming and/or helping secondary hosts. In this case "helping" means giving secondary hosts more disease resistance. (In this case "secondary hosts" are living things other than humans. Those living things can also have the disease we are eradicating.) These secondary hosts include "Aedes" spp., "Anopheles" spp. and white-footed mice. "Aedes" spp. can carry dengue, chikungunya, and Zika viruses. "Anopheles" spp. can carry malaria. White-footed mice can carry the Lyme disease bacterium.
