How do diseases spread through activities?
when disease-causing germs pass from an infected person to a healthy person via direct physical contact with blood or body fluids. when disease-causing germs pass from an infected person to a healthy person via sneezes or coughs, sending infectious droplets into the air or onto objects.
What is the agent in disease transmission?
The agents that cause disease fall into five groups: viruses, bacteria, fungi, protozoa, and helminths (worms). Protozoa and worms are usually grouped together as parasites, and are the subject of the discipline of parasitology, whereas viruses, bacteria, and fungi are the subject of microbiology.

- Animals to people:
What role does air transportation play in the spread of diseases across the globe?
Airports contribute to the potential spread of disease owing to the high number of passengers from across the world coming together in enclosed spaces, with high contact rates and several hand touch surfaces.
Do all diseases spread?
Some — but not all — infectious diseases spread directly from one person to another. Infectious diseases that spread from person to person are said to be contagious. Some infections spread to people from an animal or insect, but are not contagious from another human.

How do germs travel in a plane?
Using fluid dynamics, he created computational simulations of how air moves on airplanes, and what he found is disturbing — when a person sneezes on a plane, the airflow actually helps to spread pathogens to other passengers.
What are the challenges faced by air transport?

Which three components are needed to spread infection?
Transmission of infectious agents within a healthcare setting requires three elements: a source (or reservoir) of infectious agents, a susceptible host with a portal of entry receptive to the agent, and a mode of transmission for the agent.
What are the 3 main routes of infection?
The main routes of transmission are listed below.
- Person-to-person. Touch.
