Viruses are considered to be non-living things, and are capable of causing disease. The reason viruses are not considered living is because they lack many of the characteristics of life until they infect a host cell.
A prion.
Fomites.
Viruses ---> , there nonliving particles because they do not contain organelles that carry out cell functions, yet they are composed of an inner core of nucleic acids, surrounded by a capsid made of protein. They replicate inside living cells or "host cells" Hope this helps

Atoms are the tiny particles that make up everything, whether living or nonliving. They consist of protons, neutrons, and electrons, which come together to form molecules and ultimately all matter in the universe.
It is clear that Creutzfeldt-Jakob disease is caused by an infectious agent, but it is not yet clear what type of agent that is.
Greater density causes particles to settle faster.
Viruses are not considered living organisms but can cause disease. Prions that cause Bovine Spongiform Encephalopathy (Mad Cow disease, aka vCJD- variant Creutzfeld-Jakob disease when in humans) are not living organisms as they are just misfolded protein particles.
when you havent got enough antiboies to kill the disease causes the symptons of a disease occurs
