1. C: Novel H1N1 infection has been reported to cause a wide range of flu-likesymptoms, including fever, cough, sore throat, body aches, headache, chillsand fatigue. In addition, many people also have reported nausea, vomitingand/or diarrhea. Severe illnesses and death has occurred as a result of illnessassociated with this virus.

2. B: A 2009 H1N1 "flu shot" an inactivated vaccine (containing killed virus)that is given with a needle, usually in the arm. The indications for who can get

the 2009 H1N1 flu shot are the same as for seasonal flu shots. The flu shot isapproved for use in people 6 months of age and older, including healthy people,people with chronic medical conditions and pregnant women. The samemanufacturers who produce seasonal flu shots are producing 2009 H1N1 flushots for use in the United States this season. The 2009 H1N1 flu shot is beingmade in the same way that the seasonal flu shot is made. The 2009 H1N1 nasalspray flu vaccine a vaccine made with live, weakened viruses that do notcause the flu (sometimes called LAIV for "live attenuated influenza vaccine").The indications for who can get the 2009 H1N1 nasal spray vaccine are thesame as for seasonal nasal spray vaccine. LAIV is approved for use in healthy*people 2 years to 49 years of age who are not pregnant. The nasal spray vaccinefor use in the United States is being made by MedImmune, the same companythat makes the seasonal nasal spray vaccine called FluMist. The 2009 H1N1nasal spray vaccine is being made in the same way as the seasonal nasal sprayvaccine. About 2 weeks after vaccination, antibodies that provide protectionagainst 2009 H1N1 influenza virus infection will develop in the body. The 2009H1N1 vaccine will not protect against seasonal influenza viruses.

3. C: The 2009 H1N1 influenza vaccine is expected to have a similar safetyprofile as seasonal flu vaccines, which have a very good safety track record.Over the years, hundreds of millions of Americans have received seasonal fluvaccines. The most common side effects following flu vaccinations are mild,such as soreness, redness, tenderness or swelling where the shot was given.The Centers for Disease Control and Prevention (CDC) and the Food and DrugAdministration (FDA) will be closely monitoring for any signs that the vaccine iscausing unexpected adverse events and we will work with state and local healthofficials to investigate any unusual events.

4. D: Illness with the new H1N1 virus has ranged from mild to severe. Whilemost people who have been sick have recovered without needing medicaltreatment, hospitalizations and deaths from infection with this virus haveoccurred.

In seasonal flu, certain people are at high risk of serious complications. Thisincludes people 65 years and older, children younger than five years old,pregnant women, and people of any age with certain chronic medicalconditions. About 70 percent of people who have been hospitalized with thisnovel H1N1 virus have had one or more medical conditions previously

recognized as placing people at high risk of serious seasonal flu-relatedcomplications. This includes pregnancy, diabetes, heart disease, asthma andkidney disease.

One thing that appears to be different from seasonal influenza is that adultsolder than 64 years do not yet appear to be at increased risk of novel H1N1-related complications thus far. CDC laboratory studies have shown that nochildren and very few adults younger than 60 years old have existing antibodyto novel H1N1 Flu virus; however, about one-third of adults older than 60 mayhave antibodies against this virus. It is unknown how much, if any, protectionmay be afforded against novel H1N1 Flu by any existing antibody.

5. C: This virus was originally referred to as swine flu because laboratorytesting showed that many of the genes in this new virus were very similar toinfluenza viruses that normally occur in pigs (swine) in North America. Butfurther study has shown that this new virus is very different from whatnormally circulates in North American pigs. It has two genes from flu virusesthat normally circulate in pigs in Europe and Asia and bird (avian) genes andhuman genes. Scientists call this a "quadruple reassortant" virus.

6. C: When the novel H1N1 outbreak was first detected in mid-April 2009, CDCbegan working with states to collect, compile and analyze information regardingthe novel H1N1 flu outbreak, including the numbers of confirmed and probable

cases and the ages of these people. The information analyzed by CDC supportsthe conclusion that novel H1N1 flu has caused greater disease burden onpeople younger than 25 years of age than older people.

7. C: Its thought that novel influenza A (H1N1 Flu) spreads in the same waythat regular seasonal influenza viruses spread, mainly through the coughs andsneezes of people (not pigs) who are sick with the virus, but it may also bespread by touching infected objects and then touching your nose or mouth.

8. D: Wash your hands regularly with soap and warm for 20 seconds or cleanwith alcohol-based hand cleaner if soap and water are not available. Use apaper towel to turn off the faucet and to open the bathroom door. Wash after

eating and after using the bathroom, just like your mom always told you.

Cover your mouth and nose with a tissue when you cough or sneeze or coughor sneeze into your upper sleeve, not your hands. Put your used tissue in thewaste basket.

Consider getting the flu vaccine. The vaccine is very important for people athigh risk for serious flu complications.

Try to avoid close contact with sick people.

Avoid touching your eyes, nose or mouth. Germs spread this way.

Carry hand sanitizer as a backup for when you cant get to the sink.

Wipe down public items that everyone uses, including light switches,doorknobs, toilet handles, and toys. Alcohol-based disposable wipes are idealfor this use.

Pay attention to your overall health. Make sure you are getting enough sleep,maintaining a healthy diet and managing stress. By taking care of yourself,your body will be better able to fend off flu viruses.

9. B: In community and home settings, the use of facemasks and respiratorsgenerally are not recommended. However, for certain circumstances, afacemask or respirator may be considered, specifically for persons at increasedrisk of severe illness from influenza.

10. C: Both the flu shot (in the arm) and nasal spray form of 2009 H1N1vaccines have now been produced and licensed by the Food and DrugAdministration. The federal government has purchased a total of 250 milliondoses of 2009 H1N1 vaccine. The 2009 H1N1 vaccine first became available inearly October and more doses are becoming available every week. Vaccineavailability, however, depends on many factors so these numbers will befrequently updated. The first doses of live attenuated 2009 H1N1 flu vaccinewere administered on October 5, 2009. Administration of the 2009 H1N1 flushot began the week of October 12 2009.
