The Delaware Division of Public Health provides the following situation update on the ongoing Swine Influenza investigation. The situation continues to evolve and additional information will be released as it becomes available. There are no confirmed cases in Delaware.
As part of an ongoing investigation into an outbreak of swine influenza A (H1N1) in the United States and Mexico, public health officials believe that more cases will be identified over the next several weeks based on the rapid spread of the virus thus far. Case counts are updated daily and available at: http://www.cdc.gov/swineflu/investigation.htm.
The U.S. cases have had self-limited febrile respiratory illness and were seen on an out-patient basis only. As of April 27th at 1:00 p.m., Centers for Disease Control and Prevention (CDC) reported 40 confirmed cases from five states (CA, KS, NY, OH, and TX). None had any exposure to swine and all had viruses with identical genetic sequences that contain a unique combination of gene segments previously not seen in humans or swine in the United States. The viruses that were tested were resistant to Amantadine and Rimandatine, but sensitive to Oseltamivir and Zanamivir.
Clinicians should consider the possibility of swine influenza virus infections in patients presenting with febrile respiratory illness who:
If swine flu is suspected, clinicians should obtain a respiratory swab for Swine Influenza testing and place it in a refrigerator (not a freezer). Once collected, the clinician should contact the Delaware Public Health Laboratory at (302) 223-1520 to facilitate transport and timely diagnosis.
Please refer to CDC website for the swine case definition for the Swine Flu: http://www.cdc.gov/swineflu/casedef_swineflu.htm. For more information about swine flu: call the Delaware Division of Public Health’s Bureau of Epidemiology at (302) 744-4541 or log on to http://www.cdc.gov/swineflu. Additional information is also available by calling 1-800-CDC-INFO (1-800-232-4636).
CDC recommends the use of oseltamivir or zanamivir for the treatment and/or prevention of infection with swine influenza viruses.
Recommendations for using antiviral drugs for treatment or prevention of swine influenza will change as we learn more about this new virus.
Clinicians should consider treating any person with confirmed or suspected swine influenza with an antiviral drug. Visit: http://www.cdc.gov/swineflu/recommendations.htm for specific recommendations.
The Delaware Public Health Laboratory (DPHL) is requesting specimens from suspect Influenza-like illness cases with a history of travel to Mexico or exposure to known or suspected cases of Swine Flu.
Due to the recent cases of a novel Swine Influenza as noted above, please send positive influenza samples to DPHL. DPHL needs your help to assess the influenza subtype(s) that may be present in our communities. Therefore, when your laboratory obtains a positive rapid A influenza result, including PCR (or culture-positive), please send an appropriate sample to DPHL Appropriate sample types are listed below.
