People have already started to live wearing masks, keeping a safe distance from others, and maintaining a high level of hygiene. This paper deals with an in\u2010depth analysis of riskness associated with COVID\u201019 infections in Kolkata Municipal Corporation (KMC) at the subcity (ward) level. Attempts have been made to identify the areas with high or low risk of infections using GIS\u2010based geostatistical approach. Cosine Similarity Index has been used to rank different wards of KMC according to the degree of riskness. Four indices were computed to address intervention objectives and to determine \u201cOptimized Prevention Rank\u201d of wards for future policy decisions. The highest risk areas were located in the eastern and western part of the city, to a great extent overlapped with wards containing larger share of population living in slums and\/or below poverty level. On the other hand, highly infected areas lie in central Kolkata and in several wards at the eastern and northeastern periphery of the KMC. The \u201cOptimized Prevention Rank\u201d have indicated that the lack of social awareness along with lack of social distancing have contributed to the increasing number of containments of COVID\u201019 cases. The rankings of the wards would no doubt provide the policy makers a basis to control further spread of the disease. Since effective antiviral drugs are already in the market, the best application of our research would be in the ensuing vaccination drive against further COVID\u201019 infections.<\/jats:p>","DOI":"10.1029\/2020gh000368","type":"journal-article","created":{"date-parts":[[2021,1,19]],"date-time":"2021-01-19T13:59:27Z","timestamp":1611064767000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Risk Analysis of COVID\u201019 Infections in Kolkata Metropolitan City: A GIS\u2010Based Study and Policy Implications"],"prefix":"10.1029","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1922-4739","authenticated-orcid":false,"given":"Bibhash","family":"Nath","sequence":"first","affiliation":[{"name":"Department of Geography Hunter College of the City University of New York  New York NY USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Santanu","family":"Majumder","sequence":"additional","affiliation":[{"name":"Formerly at Department Geology &amp; Geophysics Texas A&amp;M University  College Station TX USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jayanta","family":"Sen","sequence":"additional","affiliation":[{"name":"Department of Economics West Bengal State University  Kolkata India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammad Mahmudur","family":"Rahman","sequence":"additional","affiliation":[{"name":"Global Centre for Environmental Remediation (GCER) Faculty of Science The University of Newcastle  Callaghan NSW Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"13","published-online":{"date-parts":[[2021,4,20]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S2213-2600(20)30234-4"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S2214-109X(20)30300-4"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2020.6887"},{"key":"e_1_2_10_5_1","unstructured":"Basu A.(2015).A critical appreciation of fund utilization by the people's representatives and its impact on local area development in Kolkata Municipal Corporation area since 2000(PhD thesis).
