Outbreak surveillance Central Surveillance Unit, IDSP Early Warning Signal (EWS) reports • All SSUs are required to send EWS reports (disease alerts/outbreaks) to CSU on time every week for sharing with the stakeholders • Even ‘Nil’ reporting is mandatory • An average of 20 States/UTs are reporting every week Total no. of outbreaks reported through IDSP by the States/UTs in 2008-2011 (till 26th June 2011) Year All 35 States/UTs 9 WB funded States/UTs 2008 553 400 (72%) 2009 799 488 (61%) 2010 990 619 (63%) 2011 699 516 (74%) (till 26th June ) Weekly EWS / Outbreak report submitting Status of States/UTs in 2011 (till 25th week ending on 26th June) EWS/OUTBREAK REPORT SUBMITTING STATUS STATES / UTs > 80% times reported (Consistently and timely reporting) Andhra Pradesh, Arunachal Pradesh, Assam, Bihar, Jammu & Kashmir, Karnataka, Kerala, Madhya Pradesh, Manipur, Meghalaya, Orissa, Punjab, Rajasthan, Tamil Nadu, Tripura, Uttarakhand, West Bengal 50 - 79 % times reported Chandigarh, Daman & Diu, Goa, Gujarat, Himachal Pradesh, Maharashtra, Puducherry, Sikkim, Uttar Pradesh 25 - 49 % times reported Chhattisgarh, Delhi, Haryana, Nagaland < 25 % times reported Lakshadweep, Mizoram, Jharkhand Never reported Andaman & Nicobar, Dadra & Nagar Haveli State-wise total no. of outbreaks reported through IDSP by all States/UTs in 2008, 2009, 2010 & 2011 (till 25th wk ending June 26th 2011) Sl.

No. TOOL INDICATORS 1 Is it an outbreak? (Verification of rumor / media alert done or not) Was the outbreak informed/ identified by weekly data analysis? 2 Timeliness of Response by Rapid Response Team Period between date of start of outbreak and date of response (first reported to a health worker at any health facility) Composition of outbreak response team 3 Laboratory confirmation of outbreak Type of clinical specimen Transport media Results 4 Case definition What working case definition was used? 5 Active case finding Was active house to house case search done? What population was covered? Line listing to compile cases from health facility records and active case search 6 Description of cases in time, place and person Use of epicurve, spot map, graphs? 7 Conclusion Is source of the outbreak determined? Is mode of transmission established? 8 Specific public health intervention measures undertaken Case management Control measures Outcome (CFR) 9 Recommendations What recommendations were proposed? Were they implemented? 10 Feedback given or not Written feedback Post- outbreak review Quality Assessment of Outbreaks reported by all States in 2011 (till 26 June) using 3 Essential Criteria Essential criteria Investigation within 48 hours of first case information Adequate samples sent for lab investigation within 4 days Availability of final outbreak report % of response to disease specific outbreaks (n=699) • 510 (73%) • In 302 (43%) outbreaks, appropriate human samples sent for lab investigation • 88 (13%) outbreaks etiologically confirmed • 5% Quality Assessment of Outbreaks reported by 9 WB funded States in 2011 (till 26 June) using 3 Essential Criteria Essential criteria Investigation within 48 hours of first case information Adequate samples sent for lab investigation within 4 days Availability of final outbreak report % of response to disease specific outbreaks (n= 516) • 385 (75 %) • In 242 (47 %) outbreaks, appropriate human samples sent for lab investigation • 66 (13 %) outbreaks etiologically confirmed • 4% Improving Outbreak detection and reporting 1. Early detection and response to outbreaks by identifying EWS from routine analysis of surveillance (S,P,L) data at DSU/CHC/PHC levels (by identifying any unusual rise in no. of cases) 2. Ensure 100% reporting of EWS/outbreaks by all States/Districts (even “NIL” reporting is mandated) • • • every week on time in the prescribed format 3. Avoid incomplete/incorrect data entry in the EWS format – Date of start & reporting of outbreak to be mentioned for all outbreaks – “Population affected” is the “Population at risk” Improving the quality of outbreak investigations, reporting and response 1. 2. 3. 4. Lab confirmation of diagnosis needs appropriate clinical (human) samples to be sent for lab tests Identification and Training of Epidemiologists, Microbiologists, Entomologists and RRT members at DSU / SSU levels Existence of a written case management protocol for any epidemic should be made available by the State at each PHC/CHC/District level Competency assessment tool to be utilized for improving the quality of outbreak investigations and reporting (by the Epidemiologists and Surveillance Officers) Thank you [email protected]
