INTRODUCTION: The challenges related to several viral outbreaks spanning over the centuries have exceeded human resources and capacities of the health departments to deal with the consequent adversities. Each epidemic or pandemic faced has brought out the inequalities and gaps in our systems and infrastructure. OBJECTIVES: The focus of the current paper is to do a comparative study of complex challenges faced and strategies adopted by governments during the SARS, MERS, HIV, and Ebola outbreaks. METHODS: To achieve the objective, a comprehensive summary of the challenges that the world has faced, and lessons learned from the strategic management of these viral outbreaks were analysed. CONCLUSION: An inclusive approach for the development of a multi-pronged strategic framework to benefit the concerned or affected stakeholders is discussed. These actions can guide health care workers and individuals to be aware of health hazards and complexities.
INTRODUCTION: Presently, naturalistic observation is considered as critical in understanding, and predicting the complexities of feelings and sentiments. Emerging trends of social media has completely revolutionized the process of communication. Social media, microblogging, and other means of e-communication can be used for extracting the content to decode the quality, valence, and effectiveness of communication. OBJECTIVES: In this paper, we represent the explanatory urge of mental health assessment during a pandemic situation, especially in a smart city scenario. METHODS: We reviewed the role of sentimental analysis, as an emerging application tool for emotional and behavioural analysis for the population affected by a pandemic. This paper examines the prospect of analysing the sentiments through machine learning tools to understand, describe, and predict human behavior. CONCLUSION: Further analysis of this psychological e-content can be used to understand and predict the patterns of human sentiments.
