Question

How are viruses spread?

Why should people get vaccinated?

When should I get vaccinated, or should I at all?

Thanks!

Answer 1

different viruses spead in different ways. Some are airborn, some can be spread by contact and some have to have body fluid transfer from one person to another to spread. Vaccination can stop the spread of viruses.

Answer 2

Different viruses are spread in very different ways. Some are spread by droplets of liquid from a cough or a sneeze, some are spread by physical contact, sexual contact, hand-mouth...So, it very much depends upon WHICH virus you're talking about as to how it is spread.

People should get vaccinated against diseases because it is a safe and inexpensive way to prevent disease and death.

I'm wondering if you're talking specifically about HPV and the new HPV vaccines. This virus is spread by sexual contact, and some women who are infected will develop cervical cancer as a result of that infection. Most sexually active women do become infected with this virus.

Some argue that the cost of this vaccine is too high to justify requiring vaccination by everyone. Others say that vaccination of large numbers of women will reduce the incidence of uterine cancer significantly. Unfortunately, the vaccine is not 100% effective, but it is something like 75-80% effective.

So, the choice is ultimately yours. If I had a daughter in the 12-20 age range (or even older) I would encourage her to be vaccinated against HPV.

Answer 3

besides hcbiochem 's excellent ans
here is some more info abt virus
Examples of common human diseases caused by viruses include the common cold, the flu, chickenpox and cold sores. Many serious diseases such as Ebola, AIDS, avian flu and SARS are also caused by viruses. The relative ability of viruses to cause disease is described in terms of virulence
Recently it was also shown that cervical cancer is partially caused by papillomavirus, representing evidence in humans of a link existing between cancer and an infective agent.
Prevention and treatment
Because viruses use the machinery of a host cell to reproduce and also reside within them, they are difficult to eliminate without killing the host cell. The most effective medical approaches to viral diseases so far are vaccinations to provide resistance to infection, and drugs which treat the symptoms of viral infections. Patients often ask for, and physicians often prescribe, antibiotics. These are useless against viruses, and their misuse against viral infections is one of the causes of antibiotic resistance in bacteria. However, in life-threatening situations the prudent course of action is to begin a course of antibiotic treatment while waiting for test results to determine whether the patient's symptoms are caused by a virus or a bacterial infection.

Answer 4

Depends on the type of virus.

Some need direct contact, some are airborne.

Get vaccinated if possible, just be aware of side effects. Also there are no vaccines for every known virus (example is HIV of course).
