Zoonotic Disease

Description

The illegal wildlife trade is a multi-faceted, clandestine industry that has led to the disruption of fragile ecosystems, facilitated the spread of pathogens, and has led to the emergence of novel infectious diseases in humans, domestic animals, and native wildlife(1, 2). The trade is as diverse as it is large, with live and dead wildlife representing multiple species sold to satisfy human demands for food, medicine, pets and trophies. Wildlife are harvested at astonishing numbers and used for such things as exotic pets, ornamental jewelry and clothing, and traditional Chinese medicine(3). An estimated 75% of recently emerging infectious diseases originated from animals(4), which can include both live animals and animal products.

Objective

We aim to develop an automated, real-time, comprehensive, global system for monitoring official and unofficial reports of illegal wildlife trade activity, and to determine potential hot-spot regions for emerging zoonotic pathogens along commonly utilized illegal wildlife trade routes.

INDICATOR is a multi-stream open source platform for biosurveillance and outbreak detection, currently focused on Champaign County in Illinois. It has been in production since 2008 and is currently receiving data from emergency department, patient advisory nurse, outpatient convenient care clinic, school absenteeism, animal control, and weather sources. Historical data from some of these sources goes back to 2006.

 

Objective

To examine the correlation between different types of surveillance signals and climate information obtained from a well-defined geographic area.

Description

Sixty-one percent of known disease-causing agents that infect humans can also infect animals [1]. While humans are the primary reservoir for only 3% of zoonoses, detection of zoonotic disease outbreaks remains mostly dependant on the identification of human cases [2]. Very few of the diseases that are a threat to humans are reportable in pets. Over onethird of American households include at least one pet [3]. Pets can present with clinical signs of disease earlier than people after becoming infected at the same time [4]. Pets can also become infected first and act as a source of infection for humans [5]. Detection of an outbreak in pets may then provide for warning of an outbreak that could affect humans.

Objective

This paper describes occurrences of possible co-morbidity in pets and humans discovered in a retrospective study of veterinary microbiology records and through the application of syndromic surveillance methods in a prospective outbreak detection system using veterinary laboratory orders.

In the past year, three major health care organizations – the American Veterinary Medical Association, the American Medical Association and the Society for Tropical Veterinary Medicine – have officially endorsed the concept of “One Health” recognizing the continuum of communicable infectious disease from humans to animals and animals to humans. Further, there is widespread recognition that continuous robust surveillance of animals is beneficial not only to animal health but to food safety for humans and for early warning of naturally-occurring novel diseases (all of significance have been zoonotic for the past 20 years in the US and elsewhere) and for detecting bioterrorism events (with only one exception, all human bioterrorism agents are animal diseases.)

Research has shown that Canadian First Nation (FN) populations were disproportionately affected by the 2009 H1N1 influenza pan- demic. However, the mechanisms for the disproportionate outcomes are not well understood. Possibilities such as healthcare access, in- frastructure and housing issues, and pre-existing comorbidities have been suggested. We estimated the odds of hospitalization and inten- sive care unit admission for cases of H1N1 influenza among FN liv- ing in Manitoba, Canada, to determine the effect of location of residency and other factors on disease outcomes during the 2009 H1N1 pandemic.

Objective

We sought to measure from surveillance data the effect of prox- imity to an urban centre (rurality) and other risk factors, (e.g., age, residency on a FN reservation, and pandemic wave) on hospitaliza- tion and intensive care unit admission for severe influenza.

EIDSS supports collection and analysis of epidemiological, clinical and laboratory information on infectious diseases in medical, veterinary and environmental sectors. At this moment the system is deployed in Kazakhstan at 150 sites (planned 271) in the veterinary surveillance and at 8 sites (planned 23) in human surveillance. The system enforces the one-health concept and provides capacity to improve surveillance and response to infectious disease including especially dangerous like CCHF. EIDSS has been in development since 2005 and is a free-of-charge tool with plans for open-source development. The system development is based on expertise of a number of US and international experts including CDC, WRAIR, USAMRIID, et al.

Objective:

The objective of this demonstration is to show conference attendees how one-health surveillance in medical, veterinary and environmental sectors can be improved with Electronic Integrated Disease Surveillance System (EIDSS) using CCHF as an example from Kazakhstan.

Description

Salmonella Enteritidis is dangerous for human due the reason of toxicoinfaction. These pathogen demonstrate high virulence for small children and people with chronic pathologies and can causes people die. The main source of infection to humans is birds (poultry and wild).

Wild birds represent the natural reservoir of same bacterial pathogens. It is known that Salmonella can occupy an intestinal tract of birds. This colonization in general is constant, sometimes proceeds with an alternating fever, and usually, without clinical signs. Infected birds can transmit pathogens to other isolates in close contact. This usually occurs on the nesting during seasonal migrations. In the southern region of Ukraine are several points of intersection of migration routes of wild birds on the way from Europe to Africa and Asia (National Park “Askania Nova”and others).

 

Objective

The aim of our study was to identify possible natural reservoirs of Salmonella Enteritidis among wild birds.

The usual mechanism of disease or infection transmission from vertebrate animals to humans and vice-versa is classified as zoonosis. Globally out of all microbial pathogenic disease, 61% are zoonotic with 13% species are regarded as emerging or reemerging. Studies suggest the prevalence of innumerable known and important Z/D/S such as leptospirosis, rabies, avian influenza but the extent of burden of zoonotic diseases amongst high-risk cohorts such as animal handlers within urban geography not adequately documented.

Objective:

The present study aims to document the burden of self-reported selected zoonotic diseases (Z/D/S) among animal handlers in urban areas of Ahmedabad

Description

Bovine cysticercosis is a zoonotic foodborne disease caused by Taenia saginata involving cattle as the intermediate host and humans as the final host. Humans are infected by eating raw or undercooked meat of infected cattle. Cattle are infected after grazing on pasture infected by human feces. Disease detection in cattle is performed during post-mortem meat inspection at the slaughterhouse through the identification of cysts in muscle tissue. Cysts develop from a viable stage to a degenerated stage in one to nine months, both stages being visible and distinguishable in cattle muscle. Due to the slow development of cysts and the complexity of cattle movements (up to ten different herds from birth to slaughter in France), there is a strong bias to consider the last farm location before slaughter as the location of infection.

Objective

Spatial analysis of infectious diseases enables identification of areas at high risk for infection, a useful tool for implementation of risk-based surveillance. For chronic diseases, the period between infection and detection can be long and when animal movements are important, identifying the place of infection is difficult. The objective of this study is to propose an innovative approach for spatial analysis that takes into account uncertainty regarding the location where animals were infected. An animal-herd-level weighted analysis was used and applied to bovine cysticercosis in France.
