Picture this:
Bob has the HIV virus, and he has unprotected sex with Mary, who is a stewardess. Mary goes home to Australia, and has sex with her boyfriend Joe, who is now infected. Joe goes Backpacking in Switzerland, and has sex with Tina, who he meets in a hostel, and who is now infected. Tina goes home to Her Swiss commune, where she shares a needle with 8 friends injecting heroin--now THEY are infected, and each will go about their lives infecting others, and it just keeps spreading.
You can do the same with a cold virus--but it is even more easily spread---Mary the stewardess only has to sneeze on that crowded plane, and the tiny droplets of liquid she sends out will infect 20 people, who will infect everyone they touch or speak to.
Makes you want to wash your hands, right?
Because that is the best way to prevent viruses from spreading--simple hand washing!!

Well, in the case of AIDS and HIV, you have to either have sex with someone that has the disease, and have an open wound that fluids can get into to, or get blood from that person into an open wound- like a needle stick with a dirty needle, or treating someone who has AIDS when you have an open sore and not using gloves. As far is it being spread around the world, all that has to happen is for someone that has the disease to go to another country, have sex with multiple partners, then go to somewhere else, or have the people they had sex with go somewhere else. It's really easy to understand if you think about travel methods these days, and how many people go from country to country.
As far as just regular viruses like flu or other viruses, it can be airborne, coughed or sneezed out of the person that has it and if you are in the same general area as them, you can get it. You just have to either breath in the particles, or drink from the same drinking fountain, or use the same bathroom as someone that is sick. Most viruses can live on a surface for up to 3 days. So you could get something from someone who is sick from just touching the same doorknob as they did. When you think about that, it's easy to remember to wash your hands often!!

Viruses spread by person to person contact. Either airborne, meaning someone coughs next to you, you breathe it in, then you got it. Same with contact. You touch something that an infected person handled, you are then infected. This is why washing your hands is very important. I'm sure if you did a search on this subject you would be able to find a wealth of info.

In basic terms for generalized Viruses, A Virus is a piece of DNA that floats around until your body somehow contracts it. Afterwards that DNA combines with the DNA found in one of your nucleus's. This causes the Virus to be activated causing your symptoms. Afterwards for the more infectious virus your cell explodes sending pieces of the virus's DNA everywhere to infect other cells.

well you kind of answered your own question. They spread around the world the same way. By blood or other bodily fluid contact
