Epidemiology and Surveillance
Driving without looking at the traffic? Is like making public health decisions in the absence of data
Surveillance: A role of the public health system The systematic process of collection, transmission, analysis and feedback of public health data for decision making Surveillance
Information collected by the surveillance system
How many get them?
Who get the disease?
Where they get them?
When they get them?
Why they get them?
What needs to be done as response?
A dynamic vision of surveillance All levels use information to make decisions Surveillance The private sector can treat patients but only the public sector can coordinate surveillance Collect and transmit data Analyze data Feedback information Make decisions
Syndromes under surveillance

Anticipated health problems and interventions Phases Anticipated health problems Possible Interventions Days 1-3 Injury/drowning and deaths Safe disposal of dead bodies Injury management Needs assessment for health Days 3-5 Diarrhoeal diseases Acute respiratory infections Psychosocial problems

Measured as number of deaths per 10000 population per day
Crude mortality rate (CMR) is for entire population and under 5 mortality rate (U5MR) is for children under 5 years of age
CMR = No. of deaths X 10000 Population X Period
Benchmark Mortality Rates in Emergencies
Crude Mortality Rate CMR (deaths/10,000/day)
Morbidity is the number of NEW cases of a GIVEN DISEASE among the population over a certain period of TIME
Measured per 10000 population per day
AR and CFR
Attack rate (outbreaks): The cumulative incidence of cases (persons meeting case definition since onset of outbreak) in a group observed over a period during an outbreak.
Case-fatality ratio (CFR): the percentage of persons diagnosed as having a specified disease who die as a result of that disease within a given period, usually expressed as a percentage (cases per 100).
The first onset of Measles occurred in Madhepura on the 2 nd of September 2008.
The total population affected is estimated to be 10,000 .
The Measles outbreak had a cumulative admission total of 145 males child and 155 female child.
The daily admission rate is approx 35 patients.
This outbreak claimed 6 lives
Calculate AR and CFR. What do they tell you?
Attack Rate = number of cases x 100 population at risk Attack Rate = (145+155) = .030 ; 10,000 .03 x 100 = 3.0% There was a 3.0% attack rate. Based on the population, what does this attack rate indicate? (The attack rate is very high.This is a crisis situation. Response activities should be re-evaluated.)
Case Fatality Ratio (CFR)= number of deaths x 100 number of cases = 6 = .02 (145+155) = .02 x 100 = 2.0% There was a 2.0% CFR. Based on the standards for Measles treatment, what does this CFR indicate? (This exceeds the standard of 1%. Serious action needs to be taken to improve health seeking behaviour and response activities).
Mortality in Refugee and Displaced Populations
Major causes of death in the emergency phase
Acute respiratory infections
50% - 90% of deaths in some refugee settings due to these 3 diseases
PROLONGED STRESS- NOT/ ENOUGH FOOD- ZERO HYGIENE- OVERCROWDED POPULATION DISEASE DETERMINANTS IN CAMPS
Catch-up Health and Nutrition Round :
Manpower support for Micro planning, Orientation and Monitoring
IEC ( Session site banners, banners, posters, handouts etc)
Intervention Age group Routine immunization Pregnant women and children as per EPI schedule Catch-up immunization (Measles Vaccination) 6 months to 14 years Catch–up Vitamin A doses 9 months to 5 years IFA supplementation 6months to 5 years De-worming tablets 2 years to 5 years Low osmolarity ORS All children affected with diarrhea; 6 months to 5 years Zinc Along with ORS
Prevent or detect the outbreak
- Timely, high quality mass campaigns in emergencies
- Routine childhood vaccination
Appropriate treatment of illness
- Vitamin A
Infants <6m 50,000 IU – repeat next day
Infants 6-11m 100,000 IU – repeat next day
Children 1y+ 200,000 IU – repeat next day
- Antibiotics for bacterial secondary infections
- Treat dehydration
Preventing Measles Illness and Death in Emergencies
Measles and Vitamin A Campaign
To prevent outbreaks in flood affected areas
Congregated populations displaced by flood, living in relief camps.
Target Age Group
Measles immunization: Children from 6 months through 14 years age.
Vitamin A: Children from 9 months to 5 years age
Microplan: Essential Background Information: Infrastructure and Manpower
Safety boxes = AD syringes + syringes for dilution
Vit A- 10 % reserve
CALCULATING COLD CHAIN NEEDS:
Vaccine carriers: at least 2 per team
1 for vaccine 1 for extra icepacks
Cold boxes: 1 for each storage depot
Icepacks: = vaccine carriers X 4 + large cold boxes X 50
Fuel for generator (icepacks need to be frozen 3-5 days before campaign)

Transport for teams, supervisors, coordinators, monitors
Fuel for vehicles & Hiring cost of vehicles
