South Asian Countries are Less Fatal Concerning COVID-19: A Fact-finding Procedure Integrating Machine Learning & Multiple Criteria Decision-Making (MCDM) Technique

Abstract

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which caused an outbreak of pneumonia in December 2019 in Wuhan, China, has spread rapidly throughout the world. This ongoing pandemic has resulted over 55.6 million cases of COVID-19 leading to 1.34 million deaths in more than 188 countries. However, it has been observed that the death rate is significantly in the lower side for the SAARC countries compared to the First World Nations. In this paper, the possible factors have been represented that determine this uneven distribution of COVID-19 deaths. The significance of the factors has been presented in this paper after the data analysis of the factors from 165 different countries. Based on the correlation of the factors and their critical impact towards the concerned countries death toll, the risk index of each factor has been labeled using analytical hierarchy process (AHP)-based MCDM, i.e., multiple criteria decision-making technique. The risk index of all the factors has been used to generate the susceptibility of COVID-19 for each of the countries in study, specifically the SAARC Nations. Finally, the hierarchical clustering was applied to visualize the death toll of the countries corresponding to their susceptibility index.

Role of the redox state of the Pirin-bound cofactor on interaction with the master regulators of inflammation and other pathways

“…This may cause disparity in PIR expression and lead to differential prevalence of Pirin mediated inflammatory conditions and aberrant actin cytoskeleton remodeling involved diseases (as discussed previously) among these populations. For example, NF-κB pathway, that is regulated by Pirin [ 9 , 13 ], plays a central role in pro-inflammatory cytokine response observed in COVID-19 patients [ 137 ] and interestingly, COVID-19 death rate have been comparatively lower in the South Asian countries compared to the other nations in Europe, United states and Asia [ 138 ].…”

A new approach to predict COVID-19 using artificial neural networks

“…Since the outbreak of COVID-19, the virus has evolved at a tremendous rate. One of the major causes of the failure of COVID-19 detection ( Biswas et al, 2020 , Guhathakurata, Kundu, Chakraborty, & Banerjee, 2020 , Guhathakurata et al, 2020a , Guhathakurata et al, 2020b ) from the symptoms is mainly because of the uncertain nature of the virus. As a result of which no proper dataset is available to use as a reference.…”

Variances in BCG protection against COVID-19 mortality: A global assessment

“…To prove the benefits of BCG, clinical trials are underway. Most of these trials aim to recruit frontline health workers to demonstrate the effects of BCG on total case occurrence and the severity of COVID 19 [31] . The current epidemiological data indicates that countries with very low no.…”
