In one of the Training of Trainers programme in 1990’s at Chennai, a resource person told that ‘ASA’ – Attention, Suspicion and Authority are the 3 important elements of any good surveillance.
Through high sensitivity, observational capacity, timely reporting often rare syndromes were discovered; new clinical signs innovated in the past. Lay reporting, rumor reporting, reporting any unusual events by the regular reporting centres were encouraged for adequate surveillance.
In the Feb 2016 Pulse polio, on booth day, Group D Mrs Mala regularly handling the cold chain observed and unusual event wherein VVM of a few vials rapidly converted and reached discard point between 4 to 6 hrs which she / we had not experienced in the past.
We were not able to find any visible / logical reason for this and shared with the MO / RCHO / State and the Centre – both the Govt and Development partners on same evening – 21 Feb 2016. We are indebted for the prompt response and the reply and now sharing with the TechNet viewers.
