Is a virus contagious?

Yes, all viruses that use human as their host are contangious. That is how there survive and multiple. If not, they probably aready extinct. They just differ in their route of transmission. Example, cold virus is spread by airborne droplets.\n\nSome viruses are species specific. E.g. Species specific virus that infect horses does not infect human.\nHowever, sometimes virus may undergo mutation and acquire the ability to infect human. That is why we are so afraid of bird flu, which seems to be acquiring this ability.

no\n\n\nMono is spread through saliva and is often called "the kissing disease". Although it is not highly contagious by casual contact, avoid sharing food, dishes, glasses, or utensils. Regular hand washing should also be practiced. The virus has been shown to be present in saliva for up to one year. Most cases of infectious mono are without symptoms, with resultant permanent immunity.

That someone may or may not know he or she has a virus on the computer. As a virus can infect other computers by itself. Don't easily accept files from other people unless those you really trust. If you want to accept a file, open an attachment, make sure to scan for potential virus just in case.

animals get infected by viruses...some viruses can infect both human & animals...some will show deffernt symptoms in animals than in human...some viruses show symptoms in human but they don't in animals so animals are called in this case: carriers...\nas for common cold:there are different serotypes each infect & show symptoms in different species..\nwhy do a virus infect a species not a nother??if this is what U mean: it depends on the outer structure of the virus, there are diferent types of receptors on the outer structure (envelope or wall...etc..)that will be attached to it's maching place in the cell it attackes....then the infection will begin...if the place on cell doesn't mach : no infection will be done..

Besides that fact that you can transmit your virus to one of your friends, you really should refrain from exposing yourself to any situation where your immune system would be challenged.  Physical acitivity in water and hot/cold environments is one of those situations.  Give your body the rest it needs until the cold symptoms are no longer present.

Pneumonias caused by viruses and bacteria are highly contagious especially in the early, acute stages. If you still have fever, the infection is active and your sputum (the gunk you cough up) is loaded with germs. Isolation techniques should be followed.

Its only contagious as long as the person is running a fever. Once the fever has stopped its ok. Besides those with mono are quartined until they are no longer able to spread it. If he had it in January odds are you are safe.

So far bird flu is not contagious from human to human.  So unless someone brings home a flock of chickens, I don't think you have much to worry about.

the virus likes to mutate. so even if they did have one.. it wouldn't work for very long

You get a cold from a virus.  If walking on the beach will make you more susceptible to the virus then yes you can.

This is only part true.\n\nYes, email is one means of spreading viruses. If an email user opens an attachment to an email, this email may contain a virus spreading to parts of your computer or sending it to everyone on your contacts list so that they can open it.\n\nBut, viruses are also spread by downloading files that you think are safe, but are actually hiding malicious code which can spread a virus around as well.\n\nDon't worry about which email client you use, all of them are succeptible to viruses, even Yahoo. Just make sure that you have a good anti virus program on your system and that you do regular full system scans.\n\nI have listed some good anti virus programs below.

No. Genital warts are spread by direct skin to skin contact and sex.\n\nI worried about this when I was living with my two younger brothers. I shared a bathroom with them for 5 years and I never gave them the virus!

All types of infectious conjunctivitis are contagious and can spread from one eye to the other by touching the eyes. A child can first become infected from direct contact with someone who has the infection or something that person has touched, such as a used tissue. The infectious organisms can also spread through coughing and sneezing. In addition, certain viruses spread in the summertime when children swim in contaminated water or share contaminated towels. \n\nAllergic and irritant conjunctivitis are not contagious. \n\nThe incubation time for bacterial conjunctivitis is a few days. In viral cases, it can be up to a week.

Well, I guess it depends on what kind of illness.  Is it contagious?  Otherwise, most people will be sympathetic to someone who is sick.

cold sores and genital herpes are both examples of the herpes simplex virus.  1 is a cold sore, 2 is genital herpes.  Being a virus, it stays with you forever and may periodically break out in either place, due to stress, illness etc.  It is very contagious when you have open sores and for a short period before the sores actually break out(call the prodrome period).  If you know someone with either kind, use protection.  Once you have it, you have the displeasure of owning it.

Yes, chicken pox is communicable.  Contagious or "catching," are other terms meaning roughly the same thing.  Colds, flu, all that stuff are communicable, as are measles, mumps, whooping cough; the ones you get vaccinated for as a little kid.
