Primary pathogens are capable of causing pathological changes associated with disease in a healthy individual, whereas opportunistic pathogens can only cause disease when the individual is compromised by a break in protective barriers or immunosuppression.

Some examples of reportable communicable disease include HIV, hepatitis A, B and C, measles, salmonella, measles, and blood-borne illnesses. Most common forms of spread include fecal-oral, food, sexual intercourse, insect bites, contact with contaminated fomites, droplets, or skin contact.

How many pathogens are there?

In total, there are ∼1,400 known species of human pathogens (including viruses, bacteria, fungi, protozoa and helminths), and although this may seem like a large number, human pathogens account for much less than 1% of the total number of microbial species on the planet.

What's the difference between a virus and a pathogen?

As we noted in the intro, a pathogen is an agent that can cause a disease, especially a virus or bacterium. Some fungi and algae can be pathogenic, too. Viruses cause infection, and those infections very often result in disease.

What is a pathogen 4 types and how they spread disease?

Pathogens can be transmitted a few ways depending on the type. They can be spread through skin contact, bodily fluids, airborne particles, contact with feces, and touching a surface touched by an infected person.

How do pathogens infect the body?

Microorganisms capable of causing disease—or pathogens—usually enter our bodies through the eyes, mouth, nose, or urogenital openings, or through wounds or bites that breach the skin barrier. Organisms can spread, or be transmitted, by several routes.
