Is A Viral Infection Contagious?

Yes, it is contagious.

Viral infections are caused by viruses, which need a living host in order to survive. They survive by going from host to host, therefore causing a person to be contagious.

Depending upon the specific virus, it will vary on how a virus is contagious. Some are airborne, others require the exchange of a bodily fluid, such as saliva or blood.

AIDS, the common cold, and Lyme disease are all viral infections. In order to be sure how one is contagious, it’s important to consult with your doctor. Once treatment has begun, or if the viral infection is in remission (such as herpes) then the virus isn’t contagious.

However, some are less likely to be seen than others. There is no remission for AIDS, so a person can get it if they are sexually active with someone diagnosed with it.

Understanding viral infections is the only sure way to knowing whether you are contagious or not. Since none of the viral infections are the same, it is not a simple formula to just stay away from someone and not get it. Some viral infections (such as malaria) are much more aggressive at spreading than others. Hand washing, avoiding fecal matter, and not trading bodily fluids (blood or semen) will help to prevent getting a viral infection.

Once you’ve been diagnosed with any sort of viral infection, it’s important to find out from the doctor how it is contagious. They will then tell you what you can and cannot do. Sometimes it is permanent where others will only be in the system for a few days. Whatever the outcome is, it should be strictly adhered to so that the infection doesn’t spread to others.

A viral infection means that you are carrying a virus and it can be passed on to others. So my answer is YES.

It may seem logical that by definition, any infection is contagious. But that's not true. In order for an infectious agent to be passed on to another person, it has to literally leave the body of the first person and make some sort of contact with the person to be infected. The thing is, not all infectious agents do that easily, some infections are essentially not contagious. And "contagious" usually means "easily spread." An example of a non contagious virus is the rabies virus. You cannot get it from someone else, unless for some reason the infected person bites you...or a piece of his/her infected brain or saliva gets on your open would or mucous membrane(very very rarely causes an infection). So, rabies essentially is not contagious. The cold virus, aka, rhinovirus is very contagious. Influenza is actually not that contagious compared to the rhinovirus. The virus must leave the body ("shedding" of the virus particles only happens during certain periods), survive the external environment, land on a person, get inside of a person(via blood, mucus membranes, inhalation, etc), find the right tissues(s)/organ(s) for that particular virus, and, survived the immune system. The contagiousness of virus will depend on all those...you need a green light all those things for the virus to be contagious...and that's simply not the case will all viruses. This applies to bacterial, fungal, and parasitic agents alike.

Yes, depends upon the virus as to how long they are infectious. Some it may be the first few days others longer. So it is possible not to be contagious after a certain period of time with some viruses

Yes the viral infection is contagious,everybody has virus

Yes, it is a virus, therefore contageous. Hope this helps, good luck to you.
