It depends on the specific strain of "Swine Flu". The version that pigs get has probably been around for almost as long as there have been pigs. One version of swine flu in humans was identified in the 1930's. Another started in 1976. The pandemic version of H1N1/09 began in March 2009 and still circulates in outbreaks across the world but the pandemic of this strain has been declared over. See the related question below about when swine flu started for more detail.
You could say it was spread worldwide within only 3 months! It took H1N1/09 approximately 17 months from the start with the first known cases in March 2009 until the pandemic was declared over in August 2010.
Time line:
1st identified case in Mexico made public: March 18, 2009
Officially reported to be in US: April 14, 2009
WHO Pandemic declared: June 11, 2009
Peak of the pandemic had passed according to WHO: June 3, 2010
Pandemic declared over: August 10, 2010

The pandemic swine flu has been in the news since late March 2009.
yes flu is a virus (influenza is the long name for it)
This will depend heavily on the virus you are asking about - the influenza virus is relatively hardy while the HIV virus is destroyed pretty quick.
The influenza virus is destroyed by heat at 167o - 212o F (75o - 100o C). The length of time it could survive or if it could survive at 160o is debatable.
The A and B in influenza are simply different types of influenza. * Type A: seasonal epidemics. This sub-type is based on changes in surface antigens hemagglutinin and neuraminidase. In humans subtypes H1-H3 and N1-N2 have circulated since 1918 pandemic (due to H1N1). In the last 3 decades the circulating types have been H3N2 and H1N1. * Type B: sporadic outbreaks (long term care facilities)
Influenza is a viral infection that affects the human immune system and there is no cure It takes a few weeks to recover from this virus until it mutates itself with time.
Feline influenza will usually last an estimated 7 to 10 days.
If you are asking if a virus can live very long without its host, then no. Viruses aren't alive in the first place. Because viruses can't reproduce on their own, they are not considered living organisms. Because they aren't living to begin with, they cannot die.
There is a long list of answers to your question, because patients with aids are susceptible to a long list of secondary diseases. You only asked for one, so I will give you flu, which is the abbreviation for influenza.

The virus has evolved with mankind or say mammals.
