What are 2 ways a virus spread amount humans?

Answer 1

They can be stread through direct person-to-person contact between the carrier of the virus and someone who is not infected.

They can be airborne; meaning they can be spread by water droplets that are exhaled by the infected person.

Answer 2

They could be spread through siliva, open cuts, etc. Wash your hands!

There are three main ways a virus can spread: person to person, environment to person and animal to person.

Person to person would be viruses that cannot survive for long outside of a host. These viruses travel in body fluids. You can catch these from contact with these body fluids. HIV is an excellent example, you can contract HIV from contact with an infected person's blood or sexual fluids but not from mosquitoes or from a doorknob. Environment to person would be viruses that can survive outside of the body. Rhinovirus (the common cold) is a good example. Rhinovirus can survive for about two days on some surfaces. You could catch a cold from a remote control, doorknob, telephone, steering wheel or any other surface that an infected person has touched. Animal to person is the least common by far. Parasite are more likely to travel person to person. It is rare for a virus to "make the jump" from one host species to another. But, this does happen as we have seen with the avian flu. It is even rarer for that virus to be able to spread to another human after making the initial "jump" but we have seen that happen too. No matter how you come in contact with a virus it is important to remember that your body has good defenses against them. Most viruses will need a port of entry into the body. The skin is too thick and well defended. Many viruses cannot survive the digestive tract either (although some certainly can.) Open sores or cuts and mucous membranes are the best way in. My CPR instructor calls paper cuts "hepatitis ports" for a reason. Do not rub your eyes (the best way in,) pick your nose or bite your nails with dirty hands. Wash your hands often, clean telephones, keyboards and doorknobs used by multiple people and let people know if you are carrying anything contagious. We cannot stop the spread of viruses but we can slow and limit it. :)

Answer 3

Germs are spread through many ways here is a list

.sneezing

.coughing

.sexual contact (for example rare cases such as HIV)

.body fluids

.touching a surface that has the bacteria on it

Oh and if your talking about computer virusees than :

.going onto unsafe sites

.email contacts

Answer 4

Viruses are microscopic parasites, generally much smaller than bacteria. They lack the capacity to thrive and reproduce outside of a host body. They are spread much like any other diseases like those caused by bacteria. There is the oral fecal route or transmission may involve fluid exchange. (HIV) And exposure to vectors contaminated by the infective agent. Vectors can be insects or other animals including humans.

Answer 5

Viral diseases may spread

• Through medium like air
• Fomites, i.e. objects like handkerchiefs used by the diseased person.

Answer 6

by surface contact, like handrails in a stairway and, of course, orally, by coughing in a crowd.
