Yes, and since the new flu that caused the pandemic in 2009 (H1N1/09 "Swine Flu") there have been other new types identified (and even some new strains of avian flu have been identified) around the world. The viruses that cause the flu are mutating into new types of flu all the time. Cold viruses also mutate easily and quickly, this is a reason that vaccines can not be developed in time before they mutate again leaving the vaccine ineffective). Sometimes our immune systems have antibodies against older types of flu that will work to prevent the new types that are not that much different, but then other times the new influenza virus will have mutated into types for which our prior immunities will not be effective to prevent the new flu from making us ill. We will have to either get vaccines made as we did in 2009, or we will have to leave it to our bodies to make new antibodies that will block the new flu, but we will feel the symptoms of the flu in the interim.
Mostly around Fall and Winter.

That sounds like the classic symptoms of influenza. In the Northern Hemisphere, the flu season is upon us. It is time now, in the Fall of 2011, to ready for the flu season with an annual flu vaccination.
There was a disease that was affecting humans called 'bird flu' that caused a scare a few years ago but is now extinct. it was called bird flu because it was mainly affecting birds
Flu has been around as long as man has been around. The Flu virus is spread by humans and by birds.
During fall and winter.
yes we are going to get the swine
Flu season is the period of the year when the flu virus is most active and spreads to the most other people. It's usually considered to be Fall and Winter because that's when people are gathered inside more and spread the virus around more easily.
Go to the doctor, tell your doctor you have the flu.
fever, chills, aches, all the flu stuff. vomiting & diarrhea for some people, mostly kids.
