Provider-based Sentinel SurveillanceThe 3 Functions of GeoSentinel

1. Surveillance – Response– Alarming sentinel events

2. Surveillance – ongoing trends3. Analysis of morbidity and estimating risk3. Analysis of morbidity and estimating risk

– Diagnosing the ill-returnee; the clinician perspective

– Advising the Prospective Traveler; the traveler perspective

– Defining associations between patient characteristics and disease

GeoSentinel Response Capabilities• Rapid Query-Response loop

• 55 GeoSentinel Sites• 215 GeoSentinel Network Members• ISTM members

(TravelMed; 2600 members in 75 countries)• Partners

(WHO, ProMed, IDSA, TropMed, CDC, etc)

• Outgoing Alerts/Advisories– Broadcast radius is situation dependent

• Collaboration with public health partners

Alarming Events Strategy

• Fixed list of flagged diagnoses

– Any such record entered into the central database triggers an immediate alarm

– Immediate notification of a Project Director – Immediate notification of a Project Director for decision on response

• Temporary flagged diagnoses added based on situations arising

Rare Alarming Events• Anthrax, pulmonary/cutaneous• Botulism• Chagas disease, acute• Cholera (toxigenic V. cholera)• Death• Dengue (severe/complicated)• Diphtheria

• Meningococcal meningitis• Mycobacterium tuberculosis

(MDR or XDR)• Polio• Rabies• Rickettsia prowazeki• SARS

• Diphtheria• Ebola virus• Encephalitis, acute• Hemorrhagic fever, acute• Influenza, Avian• Lassa Fever• Malaria - Atovaquone/

Mefloquine/Quinine resistant

• SARS• Smallpox• Trypanosomiasis, African• Tularemia• Yellow Fever• Yersinia pestis, plague

• Acute diarrhea : all categories of European travellers to South CentralAsia, North Africa and Middle East, but particularly classi c tourist-travellers

• P. falciparum malaria : immigrant-travellers from Italy and France whovisit friends and relatives in sub-Saharan Africa and the In dian OceanIslands.

• Thyphoid fever : travellers to South Central Asia

• Rickettsiosis : travellers to sub-Saharan Africa

• Dermatological conditions : tourist travellers to the Caribbean and Central and South America (parasitic diseases) and to North Africa, Middle East and South East Asia (Potentially rabid animal bites)

• STD : missionary expatriate and immigrant VFR traveller s to Eastern Europe, South East Asia and Caribbean.

3 deaths recorded• E.coli pyelonephritis and sepsis following a 2-month sojou rn in Spain• Dengue Shock Syndrome following a 3 week pre-arrang ed tourist trip to Phuket • P. falciparum malaria related death in an aid worker who had visited Liberia for three weeks

Febrile systemic illnesses (20%) with identified pathogen:

Gastro-intestinal : 33% of illnesses followed by febrile systemic illnesses : 20% dermatological conditions : 12%and respiratory illnesses : 8%

Malaria (5.4%) accounted for most cases followed by dengue (1.9%)

others including chikungunya, rickettsial diseases, leptospirosis, brucellosis, EBVinfections, tick-borne encephalitis (TBE) and viral hepatitis.

Dermatological conditions (12% of total) :dominated by bacterial infections, arthropod bites, cutaneous larva migrans animal bites requiring rabies post-exposure prophyl axis and also leishmaniasis, myasis, tungiasis and one c ase of leprosy.

Respiratory illness (8% of total) :• 112 tuberculosis including 6 MDR tuberculosis, • 112 tuberculosis including 6 MDR tuberculosis, • 104 cases of influenza like illness• 5 cases of Legionnaires disease.

Sexually transmitted infections (STI) : 0.6% including HIV infection and syphilis.

165 cases of potentially vaccine preventable diseases

Purpose of travel and destination specific risk factors was identified for several diagnoses such as

• Chagas disease in immigrant travellers from South America • P. falciparum malaria in immigrants from • P. falciparum malaria in immigrants from sub-Saharan Africa (SSA).

Travel within Europe is also associated with health risks with distinctive profiles for Eastern and Western Europe.

Marked increase in the number of travellers exposed in North America and

6392 patients at EuroTravNet core sites

western Europe.

Respiratory illnesses, in particular pandemic A(H1N1) influenza, influenza-like syndromes, and tuberculosis, were also observed more frequently. A significant increase in reported dengue cases in 2009 as compared with 2008 was observed (n = 172, 2.7% vs. n = 131, 1.90%). The numbers of malaria and chikungunya cases were also increasing, although not significantly.

Two deaths: visceral leishmaniasis and sepsis in a Sudanese migrant, and Acinetobacter sp. pneumonia in a patient who had visited Spain.
