5. JH Monestersky 5 Bottom Line, Up Front International Health:
To provide background, educational opportunities & your potential role
Try to do a medical rotation overseas, esp., developing country
Gain experience in nutrition [esp., peds, malnutrition [marasmus (calorie) vs. kwashikor (protein)], environmental health (food & water sanitation), entomology (medical), infect dx (measles, TB, malaria), diarrhea (ORS)
Think about MPH degree or dual MD/MPH (IH, Epi, M&CH)
Consider eventual paid or volunteer work abroad; e.g., PC (volunteer, PCMO), USDOS (RMO), DoD (A/D), NGO (MSF)
Become more familiar with CHE, Mass disasters, Refugee Medicine
International medical perspective mind-broadening
You can make a difference (even one person at a time)
Even consider specialty you choose if you want overseas work (e.g., IM/ID/TM, Ortho, GenSurg, ENT, Ophthal)
Requires change in frame of reference to gain from experience!
Carefully preplan your trip to make it meaningful & safe
Learn a language or improve your language skills
6. JH Monestersky 6 Relevance??? Are tropical diseases of just historical interest?
Emerging & reemerging diseases
Global warming is changing disease distribution (e.g., WNF, malaria)
With international jet travel, patients can show up anywhere even at a Midwest doc-in-the-box!
Future pandemics (e.g., Avian influenza)?
Bioterrorism (e.g., smallpox, anthrax)
Many diseases remain major killers world-wide (measles, diarrhea, malaria, TB)
Developing countries a Petri dish for rest of world
7. JH Monestersky 7 Monkeypox Ref: CDC MMWR 52(23):537-540; 6/13/03 Multi-state Outbreak of Monkeypox IL, IN, WI
The 1st case presented to Marshfield Clinic WI for Tx of an infected bite from a pet prairie dog (6/03).
Marshfield thought it was an orthopox by EM; specimen sent to CDC lab, which confirmed Dx by PCR.
This orthopoxvirus is similar in appearance to smallpox; with low CFR.
Human monkeypox was 1st identified in the Democratic Republic of the Congo in a a region where smallpox had been eradicated in 1968.
53 cases; resulting in 14 hospitalizations (26%).
S&S: Preceding febrile illness, papular rash, lymphadenopathy, sore throat. Rash progressed through states of vesiculation, pustulation, umbilication, encrustation. Rashes occurred on hands, trunk, extremities; many patients had initial & satellite lesions on palms, soles, extremities. Rashes were generalized in some pts.
Epid: All pts had contact with animals (Cynomys sp.) & 1 pt reported contact with a Gambian giant rat (Cricetomys sp.). Investigation revealed that a common distributor was responsible, who housed prairie dogs and Gambian giant rats together. Records revealed that the Gambian giant rats were shipped from Ghana to Texas and then, on to Illinois. Exposures were at a pet swap meet in N. WI.
FDA & CDC issued an immediate ban on importation of all rodents from Africa (order Rodentia)
8. JH Monestersky 8 Malaria Airport malaria in France
Between 1969-98, 63 cases of airport malaria have been reported in W. Europe, 24 of which occurred in France.
Most cases due to Plasmodium falciparum.
In 1994, 7 cases occurred in & around Roissy Charles de Gaulle airport (CDG), showing 4 types of exposure: employees working on airstrips or opening containers, among residents living near airport, among people living at some distance from airport after a secondary transport of vectors, & by vectors transported in luggage.
Prevention is by disinsectization of aircraft, with permethrin aerosol though there is some pyrethroid resistance in Anopheles gambiae in W. Africa.

9. JH Monestersky 9 I. Complex Humanitarian Emergencies
10. JH Monestersky 10 Definition of CHE Def: Human disaster that occurs during & follows war & civil strife
Inciting event either natural or man-made
Characterized by displacement (internal, external)
Loss of existing societal infrastructure
Concerns for personal security
90% of war related mortality is among civilian non-combatants
11. JH Monestersky 11 Refugees vs. IDPs Flight across border (R) or within border (IDP)
14M refugees
15 20M IDPs
UN & international protections vary
Difficulty in assistance (e.g., Tsunami in Sri Lanka)
12. JH Monestersky 12 Priority Needs Sanitary food
Sanitary water
Sanitary waste disposal
Shelter (planned layout of camp)
Identification of vulnerable populations
Appropriate health interventions for these populations:
Immunizations
Nutritional assessment
Food appropriate to population
Security
Communications
Transportation & distribution scheme
Internal help (military, govt, healthcare workers)
Outside help:
UNHCR
ICRC
NGO (e.g., Medecins sans Frontieres)
Office for Coordination of Humanitarian Affairs
USAID (Office of Foreign Disaster Assistance)
13. JH Monestersky 13 Government-Civilian Agency Cooperation in Crisis Management Civil-Military Cooperation:
C4 (command, control, communications, coordination) + security + logistical capabilities (resources, transportation)
DoD vs. coalition partners (e.g., NATO)
HA, MOOTW + aid agencies
Sometimes friction
Emergencies & disasters (e.g., hurricane response)
USDOS-Civilian Cooperation:
USAID, NGOs (local experts), Embassy, Beneficiary partnership
Uni/bi/multi-national, UN

16. JH Monestersky 16 III. Emerging vs. Reemerging Diseases
17. JH Monestersky 17 Emerging Diseases Newly identified disease
Increased incidence over past 2 decades
Incidence expected to increase over next 2 decades
Examples:
WNF
Avian influenza
SARS
CDC Emerging Infectious Diseases (http://www.cdc.gov/ncidod/eid/index.htm)
18. JH Monestersky 18 Reemerging Diseases Smallpox
TB
Plague
19. JH Monestersky 19 Ingredients for Emergence Pathogen adaptation & change
Virulence
Adherence
Invasiveness
Toxin production
Evasion of host immune defenses
Antibiotic Resistance
Expansion to new environments, reservoirs, vectors (microbial traffic)
Increased populations at risk
Genetic predisposition
Co-infection
Urban migration & poverty
Crowding & poor hygiene
Impaired immunity
Inadequate public health infrastructure
20. JH Monestersky 20 Combating Emerging & Reemerging Diseases Facilitate early recognition & control of new diseases
Tracking by US & Overseas Labs
Train host-nation epidemiologists
Assess & control threats
US [CDC (e.g., MMWR), USAMRIID (US Army Medical Research Institute for Infectious Dxs , GEIS (Global Emerging Infections Surveillance program), ESSENCE (Electronic Surveillance System for the Early Notification of Community-Based Epidemics)]
Network with foreign health agencies & WHO (Outbreak Reports), ISID (Promed)
Monitor drug resistant organisms [e.g., Plasmodia, enteric & other pathogens (VRE, MRSA)
Monitor for leptospirosis, yellow fever, dengue, hantaviruses
21. JH Monestersky 21 Powder Kegs for the Next Great Pandemic In the Shadow of the City
Worlds great slums
Cairo, Smokey Mountain (Manila), Rio, Calcutta, Mexico City
Worlds slums are growing rapidly (UN-HABITAT Human Settlements Program Report):
Now at 1B mark, making up 32% of global urban population
Figure will double to 2B in next 30yr unless concerted effort undertaken
In developing countries slum dwellers account for 43% of population in contrast to about 6% in more developed countries
Slums represent worst of urban poverty & inequality:
No sanitation, no education, uncounted census
Worlds rural population has reached its peak & almost all further population growth will be absorbed by urban settlements
