How do I know if I have the flu (both seasonal and H1N1/swine)?

You may have the flu if you have some or all of these symptoms:

• fever
• cough
• sore throat
• runny or stuffy nose
• body aches
• headache
• chills
• fatigue
• sometimes diarrhea and vomiting

What should I do if I get sick?

If you get sick with flu-like symptoms this flu season, you should stay home and avoid contact with other people except to get medical care. Most people with 2009 H1N1 have had mild illness and have not needed medical care or antiviral drugs and the same is true of seasonal flu.

However, some people are more likely to get flu complications and they should talk to a health care provider about whether they need to be examined if they get flu symptoms this season. They are:

• Children younger than 5, but especially children younger than 2 years old
• People 65 and older
• Pregnant women
• People who have:
  
  • Cancer
  • Blood disorders (including sickle cell disease)
  • Chronic lung disease [including asthma or chronic obstructive pulmonary disease (COPD)]
  • Diabetes
  • Heart disease
  • Kidney disorders
  • Liver disorders
  • Neurological disorders (including nervous system, brain or spinal cord)
  • Neuromuscular disorders (including muscular dystrophy and multiple sclerosis)
  • Weakened immune systems (including people with AIDS)

Also, it’s possible for healthy people to develop severe illness from the flu so anyone concerned about their illness should consult a health care provider.

There are emergency warning signs. Anyone who has them should get medical care right away.

What are the emergency warning signs?

In children:

• Fast breathing or trouble breathing
• Bluish skin color
• Not drinking enough fluids
• Not waking up or not interacting
• Being so irritable that the child does not want to be held
• Flu-like symptoms improve but then return with fever and worse cough
• Fever with a rash

In adults:

• Difficulty breathing or shortness of breath
• Pain or pressure in the chest or abdomen
• Sudden dizziness
• Confusion
• Severe or persistent vomiting

Are there medicines to treat 2009 H1N1?

Yes. There are drugs your doctor may prescribe for treating both seasonal and 2009 H1N1 called “antiviral drugs,”  like Tamiflu and Relenza.  These drugs can make you better faster and may also prevent serious complications. This flu season, antiviral drugs are being used mainly to treat people who are very sick, such as people who need to be hospitalized, and to treat sick people who are more likely to get serious flu complications. Your health care provider will decide whether antiviral drugs are needed to treat your illness. Remember, most people with 2009 H1N1 have had mild illness and have not needed medical care or antiviral drugs and the same is true of seasonal flu.

How long should I stay home if I’m sick?

CDC recommends that you stay home for at least 24 hours after your fever is gone except to get medical care or for other things you have to do and no one else can do for you. (Your fever should be gone without the use of a fever-reducing medicine, such as Tylenol®.) You should stay home from work, school, travel, shopping, social events, and public gatherings.

General Information About 2009 H1N1 Vaccines

This season, 2009 H1N1 vaccines are being made to protect against the 2009 H1N1 influenza virus (sometimes called “swine flu”). There are two kinds of 2009 H1N1 vaccines being produced: a 2009 H1N1 "flu shot" that is given with a needle, usually in the arm; and the 2009 H1N1 nasal spray flu vaccine given via a nasal sprayer.

Will the seasonal flu vaccine also protect against the 2009 H1N1 flu?

The seasonal flu vaccine is not expected to protect against the 2009 H1N1 flu.

Can the seasonal vaccine and the 2009 H1N1 vaccine be given at the same time?

Inactivated 2009 H1N1 vaccine can be administered at the same visit as any other vaccine, including pneumococcal polysaccharide vaccine. Live 2009 H1N1 vaccine (the nasal spray) can be administered at the same visit as any other live or inactivated vaccine EXCEPT seasonal live attenuated influenza vaccine (Flumist nasal spray).

Who will be recommended to receive the 2009 H1N1 vaccine?

CDC’s Advisory Committee on Immunization Practices (ACIP) has recommended that certain groups of the population receive the 2009 H1N1 vaccine when it first becomes available. These target groups include pregnant women, people who live with or care for children younger than 6 months of age, healthcare and emergency
medical services personnel, persons between the ages of 6 months and 24 years old, and people ages of 25 through 64 years of age who are at higher risk for 2009 H1N1 because of chronic health disorders or compromised immune systems.

Will this vaccine be made differently than the seasonal influenza vaccine?

No. This vaccine will be made using the same processes and facilities that are used to make the currently licensed seasonal influenza vaccines.
