The Role of Swab Tests to Decrease the Stress by COVID-19 on the Health System using AI, MLR & Statistical Analysis

Abstract

Objectives: The outbreak of the new Coronavirus (COVID-19) pandemic has prompted investigations on various aspects. This research aims to study the possible correlation between the numbers of swab tests and confirmed cases of infection, with special attention to the sickness level. Study Design: The study is carried out with reference to the Italian case, but the result is of more general importance, in particular for countries with limited availability of ICUs (intensive care units). Methods: The statistical analysis shows correlation between the number of swab tests and those of daily positive cases, mild cases admitted to hospital, intensive care cases, recovery, and death rate, and provides a basis to carry on an AI study. The results were validated using a multivariate linear regression (MLR) approach. Results: Our main result is the identification of a significant statistical effect of reduction of the pressure on the Health system as result of the increase of the tests. The relevance of this result is not confined to the COVID-19 outbreak, because the high demand of hospitalizations and ICU treatments due to this pandemic has an indirect effect on the possibility of guaranteeing an adequate treatment for other high-fatality disease, such as e.g. cardiological, and oncological. Conclusions: Our results show that swab testing may play a major role to decrease the stress on the Health system of a country. Therefore, this case study is relevant in particular for the planning of the control of the pandemic in countries with a limited capacity of admission to ICU s units.

Relationship between Average Daily Temperature and Average Cumulative Daily Rate of Confirmed Cases of COVID-19

“…Pirouz and Violini (2020), analyzed the outbreak patterns of COVID-19 by analysis of 117 countries. They suggested two mechanisms of triggering the development of the infection, namely the normal spread of an infection from one parent case and the consequence of a unique phenomenon of accumulation of contagious people [22].…”

Hybrid Deep Learning Techniques for Predicting Complex Phenomena: A Review on COVID-19

“…To predict epidemiological examples of COVID-19 cases in India, this study used MLP, vector auto-regression, and linear regression methods using COVID-19 data. Statistical analysis demonstrated a correlation that exists between the swab tests numbers and mild cases admitted to hospital, daily positive cases, recovery, intensive care cases, and death rate, which provided the foundation for an AI study [78]. A multivariate linear regression (MLR) method was used for results validation.…”

Applications of artificial intelligence in battling against covid-19: A literature review

“…To suppress the pandemic, a prompt action in identifying the suspected cases is important. In order to study the correlation between the number of swab tests and confirmed cases of infection, with attention to the sickness level, AI approaches are used in [513] . The authors report that there is correlation between the number of swab tests and daily positive cases, mild cases admitted to hospital, intensive care cases, recovery and death rates.…”
