So far, most influenza viruses isolated are 2009 H1N1 flu (sometimes called "swine flu"), the virus that has been declared pandemic by the World Health Organization. CDC expects both 2009 H1N1 flu and seasonal flu to cause illness, hospital stays and deaths this influenza season and while influenza is unpredictable, it’s possible the United States could experience an early, prolonged and severe influenza season.

CDC recommends that people with influenza-like illness remain at home until at least 24 hours after they are free of fever (100 degrees F or 37.8 degrees C), or signs of a fever without the use of fever-reducing medications. This is a change from the previous recommendation that ill persons stay home for 7 days after illness onset or until 24 hours after the resolution of symptoms, whichever was longer. The new recommendation applies to camps, schools, businesses, mass gatherings, and other community settings where the majority of people are not at increased risk for influenza complications. This guidance does not apply to health care settings where the exclusion period should be continued for 7 days from symptom onset or until the resolution of symptoms, whichever is longer.

It's uncertain at this time how serious or severe this novel H1N1 virus will be in terms of how many people infected will develop serious complications or die or how this new virus may affect the U.S. during its upcoming influenza season in the fall and winter. Because this is a new virus, most people will have little or no immunity against 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.

CDC Briefing on Public Health Investigation of Human Cases of H1N1 Flu (Swine Flu)
05/05/2009 05:49 PM
The novel H1N1 flu virus is causing illness in infected persons in the United States and countries around the world. CDC expects that illnesses may continue for some time. As a result, you or people around you may become ill. If so, you need to recognize the symptoms and know what to do.
05/05/2009 05:45 PM
At this time, CDC recommends the primary means to reduce spread of influenza in schools is to focus on early identification of ill students and staff, staying home when ill, and good cough and hand hygiene etiquette. Decisions about school closure should be at the discretion of local authorities based on local considerations, including public concern and the impact of school absenteeism and staffing shortages.

As of May 3, 226 human infections with novel H1N1 flu have been confirmed in 30 states in the United States. Yesterday, CDC reported 160 cases in 21 states. This jump in case numbers is more than likely due to catch up confirmation of lab results. As testing continues in many other states, more cases and more states are expected to be added.

Patients with chronic cardiovascular disease and cerebrovascular disease (CVD) are at increased risk of experiencing an acute exacerbation of disease during influenza epidemics.
05/02/2009 09:00 PM
It is reasonable to assume that rapid diagnostic tests that detect influenza A viral nucleoprotein antigen can detect novel H1N1 flu infection in respiratory specimens as these nucleoprotein antigens are highly conserved across influenza A viruses. However, the sensitivity and specificity of the different rapid tests is not yet known for this novel virus. CDC has received anecdotal reports of false positive and false negative results. Clinicians may consider using rapid diagnostic tests as part of their evaluation of patients with signs and symptoms compatible with influenza, but results should be interpreted with caution.

Viral antigens and nucleic acids may be focal and sparsely distributed in patients with influenza. Larger airways (particularly primary and segmental bronchi) have the highest yield for detection of influenza viruses by IHC staining. In comparison, viral RNA is more commonly detected in lower airways. Collection of the appropriate tissues ensures the best chance of detecting the virus by immunohistochemical stains and PCR tests.
