Test American pork for African Swine Fever Virus with the best ASFV technology in the world and you might be very surprised at what you find.
ASFV was expected to hit the USA in the late 70s.
Do we really know that it didn't?
Is PRRS what they say it is?
Keep researching and asking questions.
Human infections with African Swine Fever may be the biggest threat to public health these days. ASFV is spreading in China, Eastern Europe, and Korea. It is on the border between Poland and Germany. Will Germany lead the way in exploring the threat of African Swine Fever to human health?

How soon will African Swine Fever break out in Poland?
It might already be there! Give how quickly and widely it has spread in adjoining countries, the odds are that it is already in ticks and wild boar in Poland.

"On a relative risk scale with six categories from negligible to very high, five European Union countries were estimated at high (France, Germany, Italy and United Kingdom) or moderate (Spain) risk of African swine fever release, five countries were at high risk of exposure if African swine fever were released (France, Italy, Poland, Romania and Spain) and ten countries had a moderate exposure risk (Austria, Bulgaria, Germany, Greece, Hungary, Latvia, Lithuania, Portugal, Sweden and United Kingdom). The approach presented here and results obtained for African swine fever provide a basis for the enhancement of risk-based surveillance systems and disease prevention programmes in the European Union."

Background on African Swine Fever Virus as a human pathogen:
"African Swine fever is an endemic disease in sub-Saharan Africa and
many other parts of the developing world. It is caused by the African
Swine virus that primarily replicates in macrophages and monocytes
leading to the impairment of the structure and function of the immune
system of the infected organisms. Until now the African Swine epidemic
continues to spread despite all efforts to contain it. Thus, there is
an objective need for effective, safe and affordable preventive and
therapeutic approaches, in particular for effective vaccines, to
control and eventually eradicate this disease. Since the characteristic
feature of the African Swine virus is to impair the immune system and
to cause immune deficiencies in its hosts the development of vaccines
and other therapeutic approaches against the African Swine virus has
implications for other immune deficiencies or diseases. Several other
viruses are also known to cause immunodeficiency-like syndromes in
humans, including cytomegalovirus, Epstein Barr Virus
and others. Moreover, a series of cases of so-called "idiopathic"
immunodeficiencies have been documented that display
CD4+T-lymphocytopenia with opportunistic infections, but show no
evidence of HIV infection. Since antibodies for the African Swine virus
have been detected in humans, the possibility of human infection with
the African Swine virus exists and may thus far have escaped any systematic screening. Thus, any preventive and therapeutic approach to African Swine fever can have far-reaching implications to control immune deficiency conditions in humans."http://www.faqs.org/patents/app/20080207875

"The family Asfarviridae contains only a single virus species, African swine fever virus (ASFV). ASFV is a viral agent with significant economic impact due to its devastating effects on populations of domesticated pigs during outbreaks, but has not been reported to infect humans. We report here the discovery of novel viral sequences in human serum and sewage which are clearly related to the Asfarvirus family, but highly divergent from ASFV. Detection of these sequences suggests that greater genetic diversity may exist among Asfarviruses than previously thought, and raises the possibility that human infection by Asfarviruses may occur."

African Swine Fever Virus (Asfarviridae) sequences found in people with febrile illnesses
Abstract
Virus Identification in Unknown Tropical Febrile Illness Cases Using Deep Sequencing
Dengue virus is an emerging infectious agent that infects an estimated
50–100 million people annually worldwide, yet current diagnostic
practices cannot detect an etiologic pathogen in ∼40% of dengue-like
illnesses. Metagenomic approaches to pathogen detection, such as viral
microarrays and deep sequencing, are promising tools to address
emerging and non-diagnosable disease challenges. In this study, we
used the Virochip microarray and deep sequencing to characterize the
spectrum of viruses present in human sera from 123 Nicaraguan patients
presenting with dengue-like symptoms but testing negative for dengue
virus. We utilized a barcoding strategy to simultaneously deep
sequence multiple serum specimens, generating on average over 1
million reads per sample. We then implemented a stepwise bioinformatic
filtering pipeline to remove the majority of human and low-quality
sequences to improve the speed and accuracy of subsequent unbiased
database searches. By deep sequencing, we were able to detect virus
sequence in 37% (45/123) of previously negative cases. These included
13 cases with Human Herpesvirus 6 sequences. Other samples contained
sequences with similarity to sequences from viruses in the Herpesviridae, Flaviviridae, Circoviridae, Anelloviridae, Asfarviridae, and Parvoviridae
families. In some cases, the putative viral sequences were virtually
identical to known viruses, and in others they diverged, suggesting
that they may derive from novel viruses. These results demonstrate the
utility of unbiased metagenomic approaches in the detection of known
and divergent viruses in the study of tropical febrile illness.

I wonder if anyone has included African swine fever [ASF] in

and pathologically virtually indistinguishable from classical swine

China has a strong and increasing presence in Africa where the

that a returning worker could have brought back some infected pork as happened in Belgium some years ago.

[The disease, which obtained in China the name "High fever disease"
since its 1st known detection in mid-2006, was initially attributed
to a mix infection of PRRS, classical swine fever (CSF) and porcine
circovirus (PCV-2), and probably additional agents; see China's
notification to the OIE of 14 Sep 2006, included in posting
20060924.2732. According to the recent Chinese notification to the
OIE of 9 May 2007, a similar syndrome in Guandong was "probably
caused by highly pathogenic Porcine Reproductive and Respiratory
Syndrome (PRRS) virus" while "laboratory diagnosis was ongoing".
ProMED-mail commented that the apparent case fatality rate (20
percent) hardly fits the description "sub-clinical" used in the
notification, and underlined the need for additional data on the PRRS
virus, currently circulating in vast areas of China and Vietnam, and
for the exclusion of other disease agents such as avian influenza
and classical swine fever (CSF); see commentary in archived 20070514.1533.
Dr. Roeder's suggestion to include ASF virus in the diagnostic
investigations of the syndrome is justified, particularly since the
"High fever disease," according to unofficial sources, has been
observed during the past several months in more than 7 provinces of
China killing more than 20 million pigs, while the official OIE
notification of 9 May 2007 referred to one province (Guandong).

"The family Asfarviridae contains only a single virus species, African swine fever virus (ASFV). ASFV is a viral agent with significant economic impact due to its devastating effects on populations of domesticated pigs during outbreaks, but has not been reported to infect humans. We report here the discovery of novel viral sequences in human serum and sewage which are clearly related to the Asfarvirus family, but highly divergent from ASFV. Detection of these sequences suggests that greater genetic diversity may exist among Asfarviruses than previously thought, and raises the possibility that human infection by Asfarviruses may occur."
African Swine Fever Virus (Asfarviridae) sequences found in people with febrile illnesses
Abstract
Virus Identification in Unknown Tropical Febrile Illness Cases Using Deep Sequencing
Dengue virus is an emerging infectious agent that infects an estimated
50–100 million people annually worldwide, yet current diagnostic
practices cannot detect an etiologic pathogen in ∼40% of dengue-like
illnesses. Metagenomic approaches to pathogen detection, such as viral
microarrays and deep sequencing, are promising tools to address
emerging and non-diagnosable disease challenges. In this study, we
used the Virochip microarray and deep sequencing to characterize the
spectrum of viruses present in human sera from 123 Nicaraguan patients
presenting with dengue-like symptoms but testing negative for dengue
virus. We utilized a barcoding strategy to simultaneously deep
sequence multiple serum specimens, generating on average over 1
million reads per sample. We then implemented a stepwise bioinformatic
filtering pipeline to remove the majority of human and low-quality
sequences to improve the speed and accuracy of subsequent unbiased
database searches. By deep sequencing, we were able to detect virus
sequence in 37% (45/123) of previously negative cases. These included
13 cases with Human Herpesvirus 6 sequences. Other samples contained
sequences with similarity to sequences from viruses in the Herpesviridae, Flaviviridae, Circoviridae, Anelloviridae, Asfarviridae, and Parvoviridae
families. In some cases, the putative viral sequences were virtually
identical to known viruses, and in others they diverged, suggesting
that they may derive from novel viruses. These results demonstrate the
utility of unbiased metagenomic approaches in the detection of known
and divergent viruses in the study of tropical febrile illness.

"Now the disease is a continental-scale threat."
Ban on wild boar culling might be fraught with biological catastrophe
"Risks of the infection spreading are colossal, since Poland has a very big wild boar population. Infected animals will spread ASF across the entire Europe just overnight"

What every Russian journalist should know about African Swine Fever virus
Russian Scientist: ASF could become a human health risk
"The African swine fever (ASF) virus, may in the future become
dangerous for humans, according to the head of the Russian Epidemiology
Service, Chief State Sanitary Doctor Gennady Onishchenko, at the
press-conference in St. Petersburg. According to him almost all viruses
from time to time go through mutation processes which can give them some
additional functions."

Articles continue to insist ASFV does not affect humans. Is that a Big Lie?
Background on African Swine Fever Virus as a human pathogen:
"African Swine fever is an endemic disease in sub-Saharan Africa and
many other parts of the developing world. It is caused by the African
Swine virus that primarily replicates in macrophages and monocytes
leading to the impairment of the structure and function of the immune
system of the infected organisms. Until now the African Swine epidemic
continues to spread despite all efforts to contain it. Thus, there is
an objective need for effective, safe and affordable preventive and
therapeutic approaches, in particular for effective vaccines, to
control and eventually eradicate this disease. Since the characteristic
feature of the African Swine virus is to impair the immune system and
to cause immune deficiencies in its hosts the development of vaccines
and other therapeutic approaches against the African Swine virus has
implications for other immune deficiencies or diseases. Several other
viruses are also known to cause immunodeficiency-like syndromes in
humans, including cytomegalovirus, Epstein Barr Virus
and others. Moreover, a series of cases of so-called "idiopathic"
immunodeficiencies have been documented that display
CD4+T-lymphocytopenia with opportunistic infections, but show no
evidence of HIV infection. Since antibodies for the African Swine virus
have been detected in humans, the possibility of human infection with
the African Swine virus exists and may thus far have escaped any systematic screening. Thus, any preventive and therapeutic approach to African Swine fever can have far-reaching implications to control immune deficiency conditions in humans."http://www.faqs.org/patents/app/20080207875

Russian ministry of natural resources: Wild boar culling will not prevent ASF spread
"According to the ministry, the key factor behind African swine fever
outbreaks is the so-called human factor, i.e. violations of veterinary
and sanitary norms at pig farms and illegal transportation of
infected products."
