Yes, viruses do mutate very easily. This is one reason the cure for the common cold is so elusive, before a vaccine can be created for the strain of rhinovirus or other virus that is causing the currently circulating common cold, the viruses will have often mutated to a new form making a vaccine ineffective.

Why must pharmaceutical companies develop flu vaccines every year?
Influenza is an RNA virus. Being that it is an RNA virus it has a high rate of mutation that goes unchecked. This high rate of mutation leads to different strains of the influenza virus
When you have the flu does your heart rate rise?
I would think so. Fever does make your heart rate higher and with the flu comes high fever.
Why do antibiotics have an effect on Swine Flu?
They do not have an effect on swine flu, but can be helpful if a secondary bacterial infection occurs with the flu or after the flu. Antibiotics have no effect on viruses. The flu is caused by viruses. Antibiotics are for treating infections by bacteria, not for treating infections by viruses.
What is the difference between Type B flu viruses and the Swine Flu?
They are different types of influenza viruses. Human "Swine flu" (H1N1/09) is caused by Type A viruses.
What are common viruses?
the flu
What is the death rate of Swine Flu verses regular flu?
The Swine Flu has a much higher death rate than regular flu. Until a few months back the swine flu had a very high mortality rate. The medical developments have brought down the mortality rate but still there are rare cases of mortality because of swine flu. The regular flu on the other hand does not have a known profound mortality rate. The cases of deaths because of regular flu are very rare and not very common. In case of patients who contract any other infection like Hepatitis or any other infection along with a flu, the chances of mortality are high.
Is a flu virus a type of disease?
Flu viruses cause disease, they cause influenza (flu). They are the infectious agents of the flu. The viruses are submicroscopic organisms that infect your body and that give you the influenza, the disease.
Does vaccination for flu cover you for all flu?
No. Each year for the US, the CDC has epidemiologists who study the flu viruses in other parts of the world and pick the three most likely to be causing illness in our part of the world in the next flu season. Those three are then made into vaccines to include in the "regular" flu shot. It is called a trivalent vaccine, because it contains three types of flu vaccines. Usually they predict very well in choosing the right viruses to use in the vaccines, but sometimes something totally unexpected comes along from a rapid mutation that is not in the vaccine (like with the 2009 Pandemic swine flu).
What type of virus cause flu?
Influenza viruses, Types A, B, and C. The flu viruses are all in the viral family called Orthomyxoviridae.
Is Swine Flu caused by global warming?
No. Swine flu is caused by a strain of virus that is a mutation of the swine influenza virus, that is now transmittable by human to human contacts, called Novel H1N1 flu. Typically flu viruses thrive in cooler weather with lower absolute humidity levels, as evidenced by the seasonal flu each year occurring in the fall and winter months. See the related question below for more information on what caused the "Swine Flu".
What causes colds flu and AIDS?
