What is flu?
The flu (or common flu) is a viral infection that is spread from person to person in secretions of the nose and lungs, for example when sneezing. Medically, it is referred to as influenza. Flu is a respiratory infection, that is, an infection that develops primarily in the lungs. Respiratory infections caused by other viruses often are called flu, but this is incorrect. Influenza usually causes higher fever, more malaise, and severe body aches than other respiratory infections. Although other viruses may cause these symptoms, they do so less commonly.
Influenza viruses are divided scientifically into three types, designated A, B, and C. Influenza types A and B are responsible for epidemics of respiratory illness that occur almost every winter. Influenza type C usually causes either a very mild respiratory illness or no symptoms at all; it does not cause epidemics and does not have the severe public-health impact of influenza types A and B. Type A viruses are divided into subtypes and are named based on differences in two viral surface proteins called hemagglutinin (H) and neuraminidase (N). There are 16 known H subtypes and nine known N subtypes.
The flu is a common illness. Every year in the United States, on average
- 5% to 20% of the population gets the flu,
- more than 200,000 people are hospitalized from flu complications,
- about 36,000 people die from the flu or its complications.
What flu viruses does the flu vaccine protect against?
Flu vaccines are developed each year and are designed to protect against the three influenza viruses that are predicted to be the most common during the upcoming season.
The 2012-2013 influenza vaccine was made from the following three viruses:
- an A/California/7/2009 (H1N1)pdm09-like virus;
- an A/Victoria/361/2011 (H3N2)-like virus;
- a B/Wisconsin/1/2010-like virus (from the B/Yamagata lineage of viruses).
While the H1N1 virus is the same as the that in the 2011-2012 vaccine, the influenza H3N2 and B vaccine viruses are different from those used for the Northern Hemisphere for the 2011-2012 influenza vaccine.
How does the flu vaccine work to prevent the flu?
The flu vaccines stimulate the production of antibodies in the body that fight the flu virus. When the virus enters a person who has been vaccinated, the antibodies attack and kill the virus and prevent infection. Antibodies are produced against the specific strains of the virus contained in the yearly vaccine.
Flu vaccination does not protect against infection caused by microbes other than the influenza virus.
When should one receive the flu vaccine?
It is recommended to get the flu vaccine as soon as the vaccine is available in the community, even as early as August. Flu season can begin in October and last as late as May.
Who should receive the flu vaccine?
The U.S. Centers for Disease Control and Prevention (CDC) recommends that every individual over 6 months of age receive the seasonal flu vaccine. While vaccination is recommended for everyone, it is particularly important for some groups. Vaccination is especially important for people who are at high risk of developing serious complications if they get the flu, such as those with asthma, diabetes, and chronic lung disease as well as pregnant women and those over 65 years of age. It is also important for people to get vaccinated who are caregivers for or those who live with people in these risk groups.
Flu Shot Side Effects
Mild side effects usually begin soon after you get the vaccine and last one to two days. Possible mild side effects of the flu shot include:
- Soreness, redness, and swelling at the injection site
- Fainting, mainly in adolescents
- Headaches
- Fever
- Nausea
Possible mild side effects of the nasal spray include:
- Runny nose
- Wheezing
- Headache
- Vomiting
- Muscle aches
- Fever
Serious side effects usually begin within a few minutes to a few hours after receiving the shot. Possible serious side effects of vaccination include:
- Difficulty breathing
- Hoarseness
- Swelling around the eyes or lips
- Hives
- Paleness
- Weakness
- Racing heart
- Dizziness
- Behavior changes
- High fever
If you experience any of these reactions, seek medical attention immediately.

Steven Spielberg had a great day at the Academy Awards nominations, where his Civil War saga “Lincoln” led with 12 nominations.

Retirement terrifies sports stars. It truly feels like death. The end of a glittering career can feel like falling off a cliff to an athlete who thrives on fame and fortune. And the longer the career, the harder the end game seems to be. It is very sad see some of our beloved stars, such as Brett Favre, limping around the field, desperately fighting for one more moment in the spotlight.
The first week of the new year has come to an end. Remember that fitness is a life long journey. Fast food is convenient, but it can be salty. Americans eat about 3,400 milligrams of sodium a day, more than the suggested 2,300 milligrams and double the 1,500 mg for people who are over 50, are African-American, or who have hypertension, diabetes or kidney disease.
A small plane carrying six people, one of them Vittorio Missoni, a director of Italy’s famed Missoni fashion house, is missing off the coast of Venezuela, Interior Minister Nestor Reverol Torres said.




A friend of mine sent me a link to this article and I had to share it with you. Check it out below. When you know better, you do better.


A Florida man was denied bond Monday on a murder charge stemming from a weekend shooting that started with a complaint about loud music and ended with a teenager dead.
Facebook will hold a vote, possibly later this week, in which it will ask users to abolish their right to vote on changes to the social network’s privacy policies.
This is a very sad story. Sometime during the mid-afternoon hours of October 29, as Superstorm Sandy was heaving up the East Coast, Anthony Narh, a Ghanaian immigrant, limped toward his job at Empire Parking, an underground garage serving one of the toniest strips of one of Manhattan’s toniest neighborhoods. Nestled near the watery edge of TriBeCa, Empire Parking was smack in the center of an evacuation zone—and Sandy was heading straight for it.
As the first full week of normalcy after hurricane Sandy draws to a close, I have a lot to be thankful for. As I pray for the people who lost their lives and property to the storm, I am thankful for making it through without any damage. The climate is changing and we have to take this into consideration as we make future decisions. Due to the fact that I did not lose power during the storm, I was able to dedicate several hours each day to the design of my charity, Champion Spirit Foundation’s website,
The election is over and Barack Obama has made history once again….And STILL…THE PRESIDENT OF THE UNITED STATES OF AMERICA…BARACK OBAMA!! People who know boxing will appreciate that. Regardless of whether you are a republican or a democrat, you have to respect Obama’s marketing campaign throughout this election process. What have we learned from Obama’s campaign? We have learned that the ground game is the key to victory. The republicans neglected the ground game and that is why they lost.
Congrats to Linda Ikeji, whose blog, is mentioned in an article in CNN.com this morning about the Obama vs Romney presidential race. The article, written by Tolu Ogunlesi, a freelance journalist in Lagos, Nigeria. In 2009 he was awarded the Arts and Culture prize in the annual CNN Multichoice African Journalism Awards. Read excerpts below:
His reputation already in tatters after a lifetime ban by the U.S. Anti-Doping Agency, Lance Armstrong finds out Monday whether he will be scrubbed from the record books for the seven feats that made him a cycling legend.
What are your thoughts on this issue? I believe that no one should put their hands on anyone else. The girl in this situation spat on the driver, punched and tried to choke him as well. It’s difficult to judge how a person will react when they are punched. Wath and comment.
If you are one of the few who haven’t seen South Korean rapper Psy’s performance of “Gangnam Style” on YouTube (which, until I wrote these words, included me), you’re missing not only a piece of power pop, but — some hope — a harbinger of things to come for Asian music artists.
Sharing is caring. This old saying is true in every sense of the word. Thanks to all of you, who have taken the time to watch “A Dog Named Gary”. I know that you are extremely busy, so we truly appreciate you doing it. Thanks to you, our film now has about 600 views, in just a few short days. The reason why the success of this film is so important is that it shows that anyone can do this. Anyone of us, regular folks, can make movies. If I can d it, you can do it too!!
I just saw this on CNN and wanted to share it with you guys. I think that it’s a great thing that Orlando Cruz has done. This is great fro boxing, a sport which has a history of being bashful against gay people. I believe that every human being should live their lives as who they truly are. Nobody should have to hide who they are for fear of being judged or ridiculed.
