Summary of Situation 

Influenza illness, including illness associated with the novel influenza A H1N1 virus is ongoing in the United States. The May 22 FluView Report shows that influenza activity is decreasing in the United States; however, levels of influenza-like illness are higher than normal for this time of year. At this time, the majority of influenza viruses isolated in the United States are now novel H1N1 viruses.

It’s uncertain at this time how severe this novel H1N1 outbreak will be in terms of how many people infected have severe complications or death related to novel H1N1 infection. While nation-wide influenza-like-illness surveillance is trending downward, localized outbreaks are ongoing and it’s likely that such outbreaks will continue over the summer. It’s uncertain how the novel H1N1 virus will affect the upcoming 2009-2010 influenza season.

The Centers for Disease Control and Prevention continues its response to the novel H1N1 Flu outbreak. CDC's goals continue to be to reduce the spread and severity of illness and to provide information to assist health care providers, public health officials, and the public address the challenges posed by this emergency. To this end, CDC continues to develop and update guidance documents and provide other information.

CDC H1N1 Flu Website Weekly Update for Week Ending May 22, 2009

You are subscribed to updates from the Centers for Disease Control and Prevention (CDC).

UPDATE ON THE SITUATION 

A New Influenza Virus

Novel influenza A (H1N1) is a new flu virus of swine origin that was first detected in April 2009. The virus is infecting people and is spreading from person-to-person, sparking a growing outbreak of illness in the United States. An increasing number of cases are being reported internationally as well.

It’s thought that novel influenza A (H1N1) flu spreads in the same way that regular seasonal influenza viruses spread; mainly through the coughs and sneezes of people who are sick with the virus.

It’s uncertain at this time how severe this novel H1N1 outbreak will be in terms of illness and death compared with other influenza viruses. Because this is a new virus, most people will not have immunity to it, and illness may be more severe and widespread as a result. In addition, currently there is no vaccine to protect against this novel H1N1 virus. CDC anticipates that there will be more cases, more hospitalizations and more deaths associated with this new virus in the coming days and weeks.

Novel influenza A (H1N1) activity is now being detected through CDC’s routine influenza surveillance systems and reported weekly in FluView. CDC tracks U.S. influenza activity through multiple systems across five categories. The fact that novel H1N1 activity can now be monitored through seasonal surveillance systems is an indication that there are higher levels of influenza-like illness in the United States than is normal for this time of year. About half of all influenza viruses being detected are novel H1N1 viruses.

CDC Response

CDC continues to take aggressive action to respond to the outbreak. CDC’s response goals are to reduce the spread and severity of illness, and to provide information to help health care providers, public health officials and the public address the challenges posed by this new public health threat.

CDC is issuing updated interim guidance daily in response to the rapidly evolving situation.

Clinician Guidance

CDC has issued interim guidance for clinicians on identifying and caring for patients with novel H1N1, in addition to providing interim guidance on the use of antiviral drugs. Influenza antiviral drugs are prescription medicines (pills, liquid or an inhaler) with activity against influenza viruses, including novel influenza H1N1 viruses. The priority use for influenza antiviral drugs during this outbreak is to treat severe influenza illness, including people who are hospitalized or sick people who are considered at high risk of serious influenza-related complications.

Public Guidance

In addition, CDC has provided guidance for the public on what to do if they become sick with flu-like symptoms, including infection with novel H1N1. CDC also has issued instructions on taking care of a sick person at home. Novel H1N1 infection has been reported to cause a wide range of symptoms, including fever, cough, sore throat, body aches, headache, chills and fatigue. In addition, a significant number of people also have reported nausea, vomiting or diarrhea. Everyone should take everyday preventive actions to stop the spread of germs, including frequent hand washing and people who are sick should stay home and avoid contact with others in order to limit further spread of the disease.

Testing

CDC has developed a PCR diagnostic test kit to detect this novel H1N1 virus and has now distributed test kits to all states in the U.S. and the District of Columbia and Puerto Rico. The test kits are being shipped internationally as well. This will allow states and other countries to test for this new virus. This increase in testing will likely result in an increase in the number of confirmed cases of illness reported. This, combined with ongoing monitoring through Flu View should provide a fuller picture of the burden of disease in the United States over time.

U.S. HUMAN CASES OF H1N1 FLU INFECTION

WHAT YOU CAN DO TO STAY HEALTHY

• Stay informed. This website will be updated regularly as information becomes available.
• Influenza is thought to spread mainly person-to-person through coughing or sneezing of infected people.
• Take everyday actions to stay healthy.
  • Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
  • Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hands cleaners are also effective.
  • Avoid touching your eyes, nose or mouth. Germs spread that way.
  • Stay home if you get sick. CDC recommends that you stay home from work or school and limit contact with others to keep from infecting them.
