This is the complete plan
A report has been prepared on the revised strategy to strengthen Kovid-19 surveillance and response in Delhi. This report has been prepared by the National Center for Disease Control (NCDC), Union Ministry of Health and Family Welfare, Government of Delhi, Indian Council of Medical Research (ICMR) and NITI Aayog. After this, on July 10, the strategy related to coronavirus will be reviewed.
Door to door survey
The report mentions the door to door survey under the Surveillance and Response Roadmap launched on June 20
A) Already a large population is part of internal surveillance due to the additional containment zone. It contains almost all the cluster cases, which is about 43% of the total cases.
B) It also has practical difficulties related to intensive surveillance work already underway. Due to door to door survey, there may also be an obstacle in the ongoing work of contact tracing in the high risk area and the container zone.
C) Doing a door-to-door survey just once will not be so useful as the symptoms of ILI (influenza like illness) and SARI (severe acutr respiratory infections) can be seen at any time.
Based on these points, Door to Door survey is not considered suitable in Delhi at present –
The population living in different areas has been classified based on the distribution of current affairs of the corona-
1) Containment Zone (421).
2) Areolated case areas.
a) Areas in which isolated cases have been continuously reported in the last 28 days.
b) Other localities (in which isolated cases sometimes occur).
3) Areas (Societies / Villages) in which no case report has been done till date.
Components of the revised strategy-
1) Strengthening Surveillance in Containment Zone – The number of total container zones has been increased to 421 based on the review of experts. Surveillance in the Containment Zone will have to be increased with strict area control.
a) Increase house to house search through personal visits within the Containment Zone. Creating contact lists to quarantine and test and follow up high risk contacts, elderly and people with co-morbidities.
b) Buffer Zone-
House to house search and list of high risk people
SARI / ILI survey in all areas.
2) Isolated cases reported from a defined area-
Reviewing the areas in which cases are being reported continuously by the Central Surveillance Unit (CSU) and District Surveillance Officer (DSO) for the last 14 days-
– Time and geographical location basis and case mapping
– Epidemiological status assessment and tracking transmission chain
– Using ITIHAS App
Increasing contact tracing, house to house search, SARI / ILI survey, high risk people listings and special surveillance, strict quarantine and isolation
Areas where case reports are not being done yet
Societies (by RWAs)
Listing of elderly and co-morbid, blocking entry of people coming from affected areas, screening of every person at the time of entry, compulsory downloading of Arogya Setu App.
Village (by Sarpanch)
Creation of monitoring committee in the village, listing of elderly and co-morbid, monitoring of any outsiders entering the village, especially those who have come from the affected area, monitored by DSO from time to time.
Increase surveillance in certain groups
High Risk Group – People over 60 years of age and people who are suffering from any chronic serious illness like diabetes, cancer.
Special Surveillance Groups
To make aware about the rules of social distancing, mask and disinfection.
ILI and SARI surveillance will continue-
– Assessment of hidden transmission every 15 days / 30 days in all container zones.
– To conduct SARI and ILI surveys in unaffected areas from time to time.
– Lab based surveillance in non-H1N1 / influenza cases.
– Kovid testing of admitted SARI cases.
Serological survey in Delhi
Currently, a sero survey is being conducted in all 11 districts of Delhi for the evaluation of IgM (immunoglobin M) and IgG (immunoglobin G) in a population of 20,000 people (both adults and under 18 years of age). will go. This survey will be completed by 10 July 2020. The result of this survey will be able to find the current status of Kovid-19, the status of the immune system, and the future line.
