Subject: URGENT - Swine influenza reporting
Dear State Veterinarians and AVIC's:
Due to today's public health emergency preparedness declaration by DHS, I
request that all State Veterinarians and AVICs report any cases of Swine
Influenza identified in their state now and in the coming days to their
Veterinary Services Regional Office as promptly as possible.† Please
respond with information on any past or ongoing cases in your states by
close of business on Monday, April 27.† This should include any cases
reported to date that may be associated with human influenza-like illness
or the current H1N1 virus reported in people in several states.
On April 23, VS provided information to laboratories with regard to
immediate implementation of the Swine Influenza Virus (SIV) pilot project.
We are asking laboratories to send to NVSL any SIV isolates that are
difficult to subtype with current reagents or known to be associated with
human illness.† Originally, we had planned to begin with eleven
laboratories but are now extending to all laboratories.† We will be having
a call with the laboratories on Monday to discuss further.† Below is
further information on the SIV pilot project:
In† July 2008, VS began developing a pilot swine influenza virus (SIV)
surveillance program in cooperation with the CDC and other stakeholders.
The pilot SIV surveillance programís overall objectives are to benefit both
animal and human health by rapidly detecting SIV genomic changes; providing
SIV diagnostic, epidemiologic, and experimental data for the development of
improved diagnostic reagents, vaccines and biosecurity practices for swine;
and to collaborate with CDC to identify SIV viruses that may pose a threat
to human health and that could be used to develop improved diagnostic
reagents, vaccines and other disease control measures.
The SIV cases identified through this pilot will meet any one of the
following three criteria:† atypical case presentations in swine; untypeable
or novel SIV isolates; and suspected concurrent SIV infection in humans and
swine, particularly involving public swine exhibitions (e.g. fairs, shows).
The project requires a coordinated effort among Veterinary Services; the
States and their diagnostic laboratories; USDA-ARS-NADC; the National Pork
Board; the American Association of Swine Veterinarians; the CDC; and other
VS staff will be contacting you soon with additional information on this
