How can an animal virus become transferred to a human?
438655
Some viruses are not specific to animals or to humans and can be passed back and forth.  For example, the avian flu.  \nAlso, horses are susceptible to many human ailments.  These viruses are transferred just like any virus, through ingestion of some sort.  This means you breath it in if it is a virus that can survive while airborne, or you can eat it, drink it or get it into your body through sores or sensitive areas like your eyes or "other areas"(HIV).  Say an animal is sick and you kill it and eat it.  Maybe the virus withstands great heat and cooking the meat of the infected animal doesn't kill it.  Eating the meat will pass the virus.  You could touch the sick animal, get contaminated saliva on your hands and then you touch your mouth or eyes; you will get sick. \n\nMost viruses are specific to certain species though.  An animal virus only affects animals and a human virus only affects humans.  Still these viruses can mutate into a virus that affects humans and animals.  That is what is so scary about viruses.  They multiply quickly and mutations are very common.

Its virus and spread from infection with unsafe sex and infected blood exchange/ transmission from infected person.

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..

Rabies is transmitted via salvia, blood or other fluids from an infected animal or individual.\n\nRabies in humans is extremely rare.  I have never heard of a case of sexually transmitted rabies...

Transmission occurs when blood from an infected person enters the body of a person who is not infected.  \nHCV is spread through sharing needles or "works" when "shooting" drugs, through needlesticks or sharps exposures on the job, or from an infected mother to her baby during birth.

The virus is transmitted through close contact of mucous membranes, when bodily fluid is present. So, head of penis inside vagina or anus, head of penis to mouth. It's not an easy virus to transmit - it requires a certain amount of the virus to be present. The critical amounts are:\n\n1 drop of blood, or\n1 teaspoon of male ejaculate, or\n1 pint of saliva.\n\nIn other words, just kissing an HIV+ person can't pass the virus; but if someone has bleeding gums, then tiny amounts of blood in the mouth can pass the virus on through the head of a penis.\n\nIn all cases, use condoms to avoid infection.

No.  There must be an exchange of body fluids to pass on HIV, and the body fluids of the HIV+ person must come in contact with the bloodstream of the other person.  \n\nIn order to pass on the disease, the scratch would have to draw blood and the HIV positive person would have to spit in the scratch or bleed into it.  A simple scratch would not pass the virus along.

You are still transferring bodily fluids from one person to another, so definitly yes you can transfer the virus through unprotected sex.  As a general rule when in doubt be safe because your life and the quality of the rest of your life may depend on it.

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.

any transfer of bodily fluid.

Yes you can. It is possible to move the virus from the location of the outbreak to other places on the body by touching the sores. Type 1 and 2 can spread to other places on the body. The eyes, moouth, genitals, and nose are the most senitive places because they are mucus membranes. But you can also get it on your finger tips called HEPATIC WITLOW.

Here's some more info about how colds are caught:\n\nThe viruses are transmitted from person to person by droplets from coughs or sneezes. The droplets or droplet nuclei are either inhaled directly, or transmitted from hand to hand via handshakes or objects such as door knobs, and then introduced to the nasal passages when the hand touches the nose or eyes.\n\nThe virus takes advantage of sneezes and coughs to infect the next person before it is defeated by the body's immune system. Sneezes expel a significantly larger concentration of virus "cloud" than coughing. The "cloud" is partly invisible and falls at a rate slow enough to last for hours—with part of the droplet nuclei evaporating and leaving much smaller and invisible "droplet nuclei" in the air. Droplets from turbulent sneezing or coughing or hand contact also can last for hours on surfaces, although less virus can be recovered from porous surfaces such as wood or paper towel than non-porous surfaces such as a metal bar. A sufferer is most infectious within the first three days of the illness. Symptoms, however, are not necessary for viral shedding or transmission, as a percentage of asymptomatic subjects exhibit viruses in nasal swabs, likely controlling the virus at concentrations too low for them to have symptoms.

B, that's it. The idea is to stall for time until a cure is found. \n\nOh, and it can still be transferred. Be careful kids.

The HIV virus has been a living virus in the animal kingdom since time in the beginning. Your pet cat has the virus. What happen was this - as this world over populated and people began to starve, corruption in every corner of the globe, people ate parts of the "monkey" , the brains in fact, for the first time, and that is how the virus entered mankind. Now through bi-sexuality - it spread, and you know that you can be in any part of the world in less then 4-hrs - that is how it travelled into our countries. There will never be a cure for it, as man does not have the DNA link to the animal DNA - the only cure is safe sex, and unfortunately that is not working, or sinking into the heads of our young people. 4 young people and hour, under the age of 34 - (14-34) male and female, contract the AIDS virus an hour! in North America!! we are not far behind the 3rd worlds which have millions dying and dead from this uncontrollable disease. A generation of children are now orphans with both parents dead from HIV. Pass it on and only have safe sex. Good question - Check out "Bono's" site, big web and lots of info on this subject and on feed the world.

I assume you're referring to the bird flu that's currently spreading through western europe. It's important that you remember that very few birds can carry the disease; however, one of the ways that the disease spreads to humans is by contact with the feathers. The most likely ways of a human contracting the virus, though, are constant contact with the faeces of birds, as well as regular contact with their beaks. Of course, since birds preen their feathers using their beaks, it is possible that the virus could survive for a short time on the feathers, and so could be passed onto humans. If you're in any doubt as to whether you may have contracted the disease, you should go to a doctor immediately. Bird flu usually manifests itself first in the form of a minor eye infection, but can spread through the body quickly depending on the strain.\n\nIn the UK, the deadly H5N1 strain has only been confirmed to date in a single dead swan, and there are no confirmed cases of it being passed on to humans in the UK.\n\nBreeds of birds you should be especially careful with are swans, geese and ducks, as they are particularly susceptible to it and may carry it for several weeks without showing any symptoms whatsoever. Also, as they are migratory birds the risk of them carrying it from another country are greatly increased.\n\nAll that said, I wouldn't be too concerned about it; as long as you're careful and you're not in regular physical contact with birds you should be alright.\n\nAlex

Bird Flu is transmitted in the respiratory secretions of infected birds.  It is unlikely you'd ever contract the disease unless you had very close contact with live or recently deceased chickens.  Cooking kills the virus.  Currently (thank goodness), it cannot be transmitted from human to human like regular flu can.

Viruses can't replicate on their own so you have to do it in a cell culture.  Look up "cell culture" and you will find lots of information as this has been done for quite a few years now.
