Viruses cause many diseases including the common cold, AIDS, hepatitis C, polio, herpes, smallpox (which at the present time is extinct in the wild but still exists in laboratories), chicken pox, measles, and many more.
Infectious diseases spread when bacteria or viruses move from the carrier to others.
Snot, if got on other people can spread lots of germs and viruses.
The process of virus growth and development allows viruses to multiply and spread within a host's body, increasing the amount of virus that can be transmitted to others. This contributes to the spread of infectious diseases by enabling viruses to infect more individuals through close contact or exposure to contaminated surfaces.
Communicable diseases always spread from one person to another or from an animal to a person. The spread often occurs due to airborne viruses or bacteria, direct contact with infected blood or other bodily fluids.
Diseases that can be spread by dirty needles include HIV, hepatitis B, and hepatitis C. These viruses can be transmitted through contaminated blood that remains on the needle when it is shared with another person.
Neither. Communicable diseases are spread by microorganisms such as bacteria, viruses, fungi and protozoa, for example.

A carrier is a person who harbors a disease. They can spread viruses through various forms of contact with other people. Diseases continue to manifest in the descendants of the carriers.Ê
When you sanitize something, you are removing any germs or viruses that could be on the item. this completely stops the spread of germs and viruses, as long as that item remains sterile.

Everything can spread diseases. What, 'which' are you concerned about?
Plants have stronger cells walls. And viruses do spread to plants.
