Infectious diseases can be caused by many pathogens, including bacteria, viruses, fungi, and parasites that may cause illness and disease. For humans, transmission of pathogens may occur in a variety of ways: spread from person-to-person by direct contact, water or foodborne illness or aerosolization of infected particles in the environment and through insects (mosquitoes) and ticks.

Answer 2

Answer:

Infectious diseases are caused by pathogenic microorganisms, such as bacteria, viruses, parasites or fungi; the diseases can be spread, directly or indirectly, from one person to another. Zoonotic diseases are infectious diseases of animals that can cause disease when transmitted to humans.

They can spread in several different ways, including through:

1. skin contact
2. the transfer of bodily fluids
3. contact with feces
4. ingesting contaminated food or water
5. inhaling airborne particles or droplets
6. touching an object that a person carrying the pathogen has also touched
