Analysis of Covid-19 via Fuzzy Cognitive Maps and Neutrosophic Cognitive Maps.

As far world history is concerned, human being faced many problems like world war, terrorist attack, bomb blasters, natural disasters and so on. But all these problems are visible and were able to come across in few months or years. Nowadays situation is entirely different from the past world history, because all the worlds are fighting with an invisible enemy called Novel Corono virus disease (Covid-19). If we compare with other diseases like Swine flu, Ebola virus this disease is very infectious and the death rate is also severe all around the world. The covid-19 pandemic has affected everyone both physically, mentally and changed our life style. Almost all the countries are suffering from this disease and the countries are struggling to control from this epidemic. Researchers in all the disciplines are exploring ways to control this disease and trying to find a vaccine. So this is a correct situation to mathematically analyze the disease covid-19 like symptoms, spreading way and precaution method using Fuzzy cognitive maps and Neutrosophic cognitive maps. Both the methods work on expert’s opinion. Since medical field involves uncertainty and indeterminacy, we have chosen fuzzy set and neutrosophic sets for our study. [ABSTRACT FROM AUTHOR]
