Ecohealth Definitions

Ecosystem approaches to public health issues acknowledge the complex, systemic nature of public health and environmental issues, and the inadequacy of conventional methodologies for dealing with them.

Dr. David Walter-Toews, University of Guelph

The Ecohealth approach focuses above all on the place of human beings within their environment. It recognizes that there are inextricable links between humans and their biophysical, social, and economic environments, and that these links are reflected in a population's state of health.

International Development Research Centre (IDRC)

Its approach is inherently transdisciplinary and recognizes complex biophysical, social, cultural, political and economic relationships between the ecosystem and human health.

-National Council for Science and the Environment

BACKGROUND

Wildlife serves as a reservoir for many diseases common to domestic animals and humans. Generally, wildlife zoonotic disease is more easily prevented than treated. Many wildlife zoonotic diseases are so common in nature, so rare in humans, or so mild in their symptoms, that wild animals pose a minimal health risk to people. However there are important and need to understand and study due to possible emergence – Emergence need to be controlled via surveillance.

FACTS ABOUT WILDLIFE AND ZOONOSES

30

Page 31: CONNECTING ECO-HEALTH COMMUNITY TO … ECO-HEALTH COMMUNITY TO WILDLIFE ZOONESES Shukor Md Nor (DVM, PHD) School of Environment and Natural Resources Faculty of Science and Technology

Example 1 – Demographic Change: Increase Population to Increase Outbreak

Outbreaks were positively correlated with growing population densities where 60.3% were zoonoses and 71.8% of these originated in wildlife. Jones, Patel, Levy, et. al. Nature, 2008 Feb. 21; 451 (7181):990-3

Page 32: CONNECTING ECO-HEALTH COMMUNITY TO … ECO-HEALTH COMMUNITY TO WILDLIFE ZOONESES Shukor Md Nor (DVM, PHD) School of Environment and Natural Resources Faculty of Science and Technology

Example 2 – Change Agriculture Pratices to Increase Emergence

Changing agricultural practices produced another outbreak of zoonotic disease, Nipah virus infection, in Malaysia in 1998–1999.8 Deforestation and intensive fruit tree cultivation combined with increased pig farming to elevate the exposure of pigs to fruit bats subclinically infected with and shedding Nipah virus. The virus rapidly spread through the country’s pig population, certainly through trade and possibly also between farms by dogs and cats. Humans in direct contact with pigs then acquired the infection and its often-fatal encephalitis.

32

Page 33: CONNECTING ECO-HEALTH COMMUNITY TO … ECO-HEALTH COMMUNITY TO WILDLIFE ZOONESES Shukor Md Nor (DVM, PHD) School of Environment and Natural Resources Faculty of Science and Technology

Example 3 – Decrease Host Species Diversity and Increase Prevalence

Explanation 1

Dilution effect, whereby increasing species diversity decreases disease prevalence by diluting the availability of competent hosts with increased numbers of non competent hosts.

a dilution effect could occur if 1) individuals of the host species remain as species diversity decreases, 2)the disease is spread within the host species through direct encounters (such as biting), and 3) presence of other species causes encounters among the host species to decrease.

- Implication for conservation

Increased Host Species Diversity and Decreased Prevalence of Sin Nombre Virus Laurie J. Dizney and Luis A. Ruedas (2009)

Page 34: CONNECTING ECO-HEALTH COMMUNITY TO … ECO-HEALTH COMMUNITY TO WILDLIFE ZOONESES Shukor Md Nor (DVM, PHD) School of Environment and Natural Resources Faculty of Science and Technology

Explanation 2

Encounter reduction - as more species, and more individuals within those species, are added to the community, the number of potential disease-transmitting encounters decreases because other species are non-host (not competent, or non-amplifying) species.

Explanation 3

Competition - if increasing species diversity increases the number of competitors in an ecosystem, thereby increasing the amount of time a host species has to spend securing limited resources (food, nest sites), in turn decreasing the time spent on intraspecies encounters.

34

Page 35: CONNECTING ECO-HEALTH COMMUNITY TO … ECO-HEALTH COMMUNITY TO WILDLIFE ZOONESES Shukor Md Nor (DVM, PHD) School of Environment and Natural Resources Faculty of Science and Technology

Explanation 4

Predation – if predation and competition are decreased or absent in a community, a zoonotic release of predatory and competitive controls appears to have occurred, infection prevalence will increase drastically.

The implications of wildlife EIDs are twofold: i) emerging wildlife diseases cause direct and indirect loss of biodiversity and ii) add to the threat of zoonotic disease emergence.

Page 36: CONNECTING ECO-HEALTH COMMUNITY TO … ECO-HEALTH COMMUNITY TO WILDLIFE ZOONESES Shukor Md Nor (DVM, PHD) School of Environment and Natural Resources Faculty of Science and Technology

Example 4 – Decrease Habitat size (fragment) Increase Prevalence

Landuse change for development reduced habitat size. Resources availability are reduced and increased stress on wildlife. High stress allow to increase prevalence.

WILDLIFE ZOONOSES – RODENT HOST OR RESERVOIR

37

Page 38: CONNECTING ECO-HEALTH COMMUNITY TO … ECO-HEALTH COMMUNITY TO WILDLIFE ZOONESES Shukor Md Nor (DVM, PHD) School of Environment and Natural Resources Faculty of Science and Technology

Rodents have proven to be of increasing importance in transmitting diseases to humans in recent decades, through the emergence of worldwide epidemics trough the emergence of diseases (e.g. leptospirosis and scrub typhus).

From wild to anthropized habitats, rodents can be reservoirs, hosts or vectors of infectious organisms.

Occupying almost all biotopes and by rapidly adapting to environmental changes, rodents are fundamental in the maintenance and transmission of an impressive number of infectious organisms to humans.

Investigations of parasites and pathogens in murine rodents have helped to describe the implication of the main species and understand the different ways of transmission.

Why Rodents ?

Page 39: CONNECTING ECO-HEALTH COMMUNITY TO … ECO-HEALTH COMMUNITY TO WILDLIFE ZOONESES Shukor Md Nor (DVM, PHD) School of Environment and Natural Resources Faculty of Science and Technology

They are known to transmit diseases and act as reservoir host for many zoonotic pathogens including parasites that pose a health risk to humans (Walsh et al., 1993; Mayer et al., 1995; Singleton et al., 2003).

Endo-parasites of rodents play an important role in the zoonotic cycles of many diseases, e.g. schistosomiasis and angiostrongyliosis. Several studies on endoparasites of commensal and forest rodents have been carried out in Malaysia

39

Why Rodents ?

Page 40: CONNECTING ECO-HEALTH COMMUNITY TO … ECO-HEALTH COMMUNITY TO WILDLIFE ZOONESES Shukor Md Nor (DVM, PHD) School of Environment and Natural Resources Faculty of Science and Technology

Why Rodents?

Some rodent-reservoir zoonoses are ‘sleeping giants’ that may awake at any time.

A crucial point here is that zoonotic pathogens that are virulent in humans are typically avirulent in their natural reservoirs: the same pathogens are therefore often medically important but archetypically ‘endemic’ in a rodent population.

Disease: health effects on humans, population effects on rodents Michael Begon

Rodents are a key mammalian group and are highly successful in adapting to many environments throughout the world.

There are more than 1700 species of rodents identified in the world (RatZooMan, 2006).

How about Bats?

CONCLUSION

It is uncertain if the leptospiras are transmitted from specific animal species or all the animals are the potential reservoir for the leptospiras.

It is still uncertain if the outbreak of leptospiras are initiated from the host/ reservoir or environment or combination of all factors.

This study will uncover the general pattern of how the leptospiras are transmitted to human.

The population and ecological data will be used to generate a suitable (and practical) control method of the hosts/ reservoirs, thus the leptospirosis cases can be controlled.

Research Questions: Source of tick infestation

Human otoacariasis is not a natural occurrence but rather accidental

Human may be infested when living, working or conducting activities in close contact with tick-infested animals or close to the environment where ticks naturally occur

There are also possibilities for animals (shrews & rodents)

to introduce the ticks into houses and compounds (Mariana, pers. comm)

INTRODUCTION

Recently, number of Emerging infectious disease-EIDs

especially from wildlife have risen in the last few

decades.

The main factor that brought in EIDs include

urbanization, rising human population, agricultural

activities, wildlife trade, loss of biodiversity, pathogen

from invasive species and global warming.

Blood parasites play a fundamental role in the ecology

and evolution of birds as they are able to affect the

fitness and survival of their hosts.

Forest fragmentation

Forest fragmentation??

Forest fragmentation occurs when a large

continuous forest reduced to smaller fragments

that are isolated by surrounding due to

anthropogenic activities.

It also includes a subdivision of forest patches

into more isolated fragments by expanding urban

areas, agriculture and other types of land uses

(Navjot et al., 2011).

Parasite prevalence vs Forest

fragmentation

Fragmentation process which increase edge effect may alter host-parasite relationship through:

1) Enhancing the ability of parasite which easily infected edge areas to infect the interior community.

2) Increasing edge effect allows contact between bird species that nesting in nearby habitat which resulting to exposure of fragment inhabitants towards new species or vector.

3) Loss of habitat for nesting forcing nest re-use.

4) Social and physiological preassure which related to reduction in habitat quality resulted in pathogenesis which consequently affecting fitness.

Conclussion Parasite prevalence is higher in fragmented forest compared to continuous

forest.

In general, parasite prevalence is higher in small patches compared to

larger patches. But, there were exception in Ayer Hitam forest (largest

fragment with highest parasite prevalence).

Aegyptianella showed the highest prevalence with 41%, followed by

Plasmodium (31.4%) and Leucocytozoon (30.5%), whereby Trypanosoma

and Ehrlichia have the lowest prevalence of 4.8% respectively.

Oriental scops-owl (Otus Sunia) was found to be the highest infected

species where 7 from 8 individuals sampled were infected primarily with

Plasmodium and Leucocytozoon. This was followed by olive-winged bulbul

(Pyncnonotus plumosus) and White-rumped shama (Copsychus

malabaricus) with 57.1% and 53% respectively.

ZOONOSES

1. Continue with OneHealth Program – at Country level

2. Establish Research Sub-group at Department level

3. Research Sub-group need to communicate at national

level

4. Enhance the existing research (wildlife zoonoses)

e.g. MyOHUN

5. Organise meeting, seminar and training.
