Daszak et al, 2000“The phenomenon of emerging and reemerging infectious diseases is driven by various anthropogenic factors, including the following: genetic and biological factors, such as microbial adaptation to macro- and microenvironmental changes along with changes in host susceptibility to infection; environmental factors, including climate change, changes in ecosystems, and changes in human and animal population densities; and socioeconomic and political factors, such as increasing international travel and commerce, social inequality, poverty, conflict, famine, lack of political will, and changes in economic development and land use.” Gebreyes et al, 2014Slide4

How Many Undetected Viruses Are There?Stephen Morse - twenty years agoCalculated were 1 million viruses of vertebrates (20 viruses X 50,000 vertebrates)Anthony et al. 2013 based on testing in Indian flying fox estimated 58 viruses X 5,486 known mammalian species = 320,000 unknown viruses that infect mammals MORE TO COME!Slide5

What Can We Do?“While it has been possible to eradicate certain infectious diseases (smallpox and veterinary disease rinderpest), and to significantly control many others…, it seems unlikely that we will eliminate most emerging infectious diseases in the foreseeable future…Microbial advantages can be met and overcome only by aggressive vigilance, ongoing dedicated research, and rapid development and deployment of such countermeasures as surveillance tools, diagnostics, drugs, and vaccines. The battle against emerging infectious diseases is a continual process; winning does not mean stamping out every last disease, but rather getting out ahead of the next one.”- Morens and Fauci, PLOS Pathogens, 2013Slide6

Slide10

Key Questions in Determining EAD ResponseIs this a new agent or disease?Does it affect public health?Is it transmitted in meat products?Does it affect swine health?Is this a primary pathogen?What is the scope of the problem? Does it occur in the United States? If so, what is its geographic distribution?How is it being diagnosed?Do we know how to control it at the farm?

How long has it been here?Slide11

Response OptionsWithin U.S. No responseTargeted educational messages/programsResearchField investigative studies – could be government and industry teamCertification of herd for absence of disease and its risk factorsApply interim control measuresOutside U.S.Monitor situation through various sources of informationProvide a technical team to affected countryConduct surveillance in the U.S.Revise import policies for animals and productsSlide12

How Are We Going to Address the Challenges?Slide18

VS Framework for Response to Emerging Animal Diseases in U.S. Developed by VS Executive TeamLed by Dr. T.J. Myers, assisted by Dr. Brian McCluskeyPresented in June 2014 to State Veterinarians and AAVLD Laboratory DirectorsPublished as a Stakeholder Registry Announcement with comments due January 16, 2015Slide19

Goals in Addressing Emerging DiseasesGoal 1: Undertake global awareness, assessment and preparedness for animal diseases or pathogens not currently in the United States that may be of animal or public health concern or have trade implications.Goal 2: Detect, identify and characterize disease events.Goal 3: Communicate findings and inform stakeholders.Goal 4: Respond quickly to minimize the impact of disease events.Slide20

G1: Global Awareness, Assessment, and PreparednessVS recognizes the need to have an enhanced system for detecting emerging diseases in the United States and other countries.For VS, the Center for Epidemiology and Animal Health’s (CEAH) Risk Identification has been charged with identifying emerging diseases globally.VS will evaluate and monitor global emerging diseases and develop science-based options for response.Slide21

G1: Global Awareness, Assessment, and PreparednessCEAH will collaborate with other areas of VS and APHIS, as well as with other government and Tribal agencies, industry, and other stakeholders to identify and describe emerging animal diseases (both internationally and domestically).International contacts: IS, IICA, OIRSA, PANAFTOSA, OIE, FAO, WHO, etc.Domestic partners: VS, veterinarians, producers, livestock markets, diagnostic laboratories, universities, State animal health officials, public health and wildlife health officials, FDA, CDC, DOI, DHS, DOD, etc.VS will provide a broad scope of information to stakeholders, decision-makers, and incident responders by incorporating both international and domestic perspectives.Slide22
Slide23

G2: Detect, Identify, and CharacterizeA variety of sources or systems can aid in the detection of an emerging animal disease in the United States. Strong partnerships and constant communication among these partners is critical to early awareness that an emerging animal disease may exist.VS will employ passive and active systems to detect emerging diseases, including mandatory reporting.Slide24

Enhanced passive surveillance provides a framework for reporting disease events that meet syndromic case definitions or observations without a specific disease diagnosis.VS is collaborating with DHS and other stakeholders on the development of a systemof reporting such events through EPS.G2: Detect, Identify, and CharacterizeSlide25

National List of Reportable Animal Diseases (NLRAD)The NLRAD is a proposed uniform, science-and policy-based, standardized list of animal diseases. It provides the basis for consistent reporting with uniform case findings and reporting criteria.The development of this list has been a collaborative effort between VS, USAHA, and AAVLD.G2: Detect, Identify, and CharacterizeSlide26

NLRAD Historical Overview1990’s National list of reportable diseases discussed2006  USAHA officially identifies need for National list, recommends review of State / Federal reporting requirements. 2007  USDA Review Summary presented. Review identified lack of standardization on reporting and state lists.Resolution #9 to develop a national list of reportable diseases based on the OIE list, VS support of Resolution #9.2008  Presented to VSMT with approval to move forwardResolution #10; NAHRS Steering committee and VS-CEAH-NSU tasked with development of list, case definitions and reporting criteria for each disease, VS support of Resolution #10

2009  Updated review of State / Federal reporting requirements, NAHRS discussions, sought internal and external input, case criteria development, and white paper (first draft)

2011/12  National Assembly of State Animal Health Officials (NASAHO) resolution of support for a U.S. NLRAD

2013-2014

 Determination to make mandatorySlide27

NLRAD – Format of Reportable Animal Disease ListSlide28

NLRAD – Emerging DiseaseIn addition to the listed notifiable diseases, these emerging animal disease conditions are notifiable and must be reported: Any animal disease or infection not known to exist in the United States, including a new strain of a known disease occurring in any animal species, including wildlifeEmerging animal disease with zoonotic potentialUnexpected and unexplained increase in morbidity or mortality of diseased animalsEvidence of a change in the epidemiology of a known animal disease such as increased pathogenicity, expanded host range, or clinical signs that do not fit the classical pictureExotic vectors (flies, myiasis, acariases (mites) and ticks), if identified, should be reported to State and Federal animal health officials for further investigation.Slide29

NLRAD – Next StepsPresented in June 2014 to State Veterinarians and AAVLD Laboratory DirectorsPublished as a Stakeholder Registry Announcement with comments due January 16, 2015Developing work plan for proposed rule Developing guidelines for implementationSlide30

G2: Detect, Identify, and CharacterizeOnce initial detections of disease have been identified and reported and it is determined that further information is needed, VS in collaboration with stakeholders could conduct a field study. A top priority in addressing an emerging disease is to gather information on key considerations to determine the best options for engagement.VS will discuss with State animal health officials and industry representatives to aid in decision-making on the appropriate level of engagement.VS will collaborate with stakeholders to rapidly investigate and assess emerging diseases.Slide32

G3: Communicate Findings and Inform StakeholdersVS will serve as the nationally recognized source for official information and must be in regular communication with relevant stakeholders.VS will publish analyses and reports that contain aggregated data.While maintaining appropriate data security, VS will serve as the national repository for shared information on emerging disease events.Slide34

G4: Respond to Minimize ImpactsEmerging disease response is different from a foreign animal disease response.For emerging diseases, VS will undertake adaptive responsive measures, rather than a predetermined control action. Range from information dissemination to full mobilization for rapid eradication.Response will be done collaboratively with the affected industry, States and other affected stakeholders.Unknowns may limit response to understanding the epidemiology and ecology of the disease and rapidly sharing information and intervention options.If control or eradication measures are recommended, VS will work with industries and States to identify appropriate compensation mechanisms.“Response” to emerging diseases does not always necessitate depopulation.Slide35

G4: Respond to Minimize ImpactsVS may form collaborative State-Industry-Federal working groups, deploy rapid response assessment teams, or utilize the National Incident Management System and incident management teams. Other actions may include:Diagnostics and vaccine developmentEducationImplementation of certification programsControl measuresIdentification of research prioritiesVS will lead the collaborative development and implementation of emerging disease response options.Slide36

Example of Submitted Comments“NCBA supports the rapid detection and response to emerging animal diseases as a USDA, APHIS, VS core business practice.” “… puts undue burden on the laboratories to keep track of and report every occurrence of common endemic diseases to every state they receive samples from…this document says the veterinarian is also required to report the disease occurrence so if both the lab doing the testing and the veterinarian are reporting there will be duplicate reporting.”“We fully support the proposal of expanding the reporting requirement to any individual, producer, veterinarian, laboratory personnel, or others with knowledge of the occurrence or suspected occurrence of notifiable diseases. If there are circumstances where duplicate reporting is not necessary, those instances should be clarified in the proposed rule. We suggest that it be made mandatory for laboratories to report NLRAD results to the animal health officials in the state where the samples originated. Furthermore, we see tremendous value in laboratories not just reporting positive results from the listed diseases, but also negative results.”“The requirement for ‘anyone’ with knowledge or suspicion of disease presence to report should be confined to veterinarians and diagnostic laboratories. Animal owners are not likely to be aware of the NLRAD and are not necessarily trained to recognize diseases or conditions expected to be reported.”“I am writing to encourage the inclusion of toxicoses on the NLRAD.”Slide37

Committee DeliberationsThe USDA requests that the Committee deliberate on the NLRAD and a national framework for emerging disease response in order to:Provide feedback on the strengths, weaknesses, value, and feasibility;Provide feedback on key issues such as diseases to include in the NLRAD (see list in concept paper), who should be required to report and to whom, what should be reported, timelines for reporting, triggers for reporting emerging diseases, and the process to determine the appropriate response to an emerging disease; and 3. Recommend actions USDA could take to promote acceptance and support among State and industry stakeholders.
