“…This system provides nationwide surveillance of the infectious diseases. The other notable solutions that have demonstrated effectiveness in terms of privacy protection are, digitally controlled health management system [52], privacy-aware energy-efficient framework (P-AEEF) protocol [53], spatio-temporal trajectory approaches with privacy [54], encryption mechanisms [55], and surveillance system [56]. All these solutions have demonstrated effectiveness for preserving people's privacy when data are collected/reported by the users for analysis or determining the probability of exposure.…”

With the advent of the pandemic (e.g., novel corona virus disease 2019 (COVID-19)), a tremendous amount of data about individuals are collected by the health authorities on daily basis for curbing the disease’s spread. The individuals’ data collection/processing at a massive scale for community well-being with the help of digital solutions (e.g., mobile apps for mobility and proximity analysis, contact tracing through credit card usage history, facial recognition through cameras, and crowd analysis using cellular networks data etc.) raise several privacy concerns. Furthermore, the privacy concerns that are arising mainly due to the fine-grained data collection has hindered the response to tackle this pandemic in many countries. Hence, acquiring/handling individuals data with privacy protection has become a vibrant area of research in these pandemic times. This paper explains the shift in privacy paradigm due to the pandemic (e.g., COVID-19) which involves more and detailed data collection about individuals including locations and demographics. We explain technical factors due to which the people’s privacy is at higher risk in the COVID-19 time. In addition, we discuss privacy concerns in different epidemic control measures (ECMs) (e.g., contact tracing, quarantine monitoring, and symptoms reporting etc.) employed by the health authorities to tackle this disease. Further, we provide an insight on the data management in the ECMs with privacy protection. Finally, the future prospects of the research in this area tacking into account the emerging technologies are discussed. Through this brief article, we aim to provide insights about the vulnerability to user’s privacy in pandemic times, likely privacy issues in different ECMs adopted by most countries around the world, how to preserve user’s privacy effectively in all phases of the ECMs considering relevant data in loop, and conceptual foundations of ECMs to fight with future pandemics in a privacy preserving manner.

“…Implementation of physical distance restrictions in public spaces plays an important role in controlling or slowing the spread of the coronavirus during the COVID-19 pandemic (CDC, 2020;Su et al, 2021). The policy for handling the COVID-19 pandemic will increase the personal distance by at least 180 cm (Jasinski, 2020).…”

“…Regarding the spread of the COVID-19 pandemic, Su et al (2021) suggest that the longer people stay at an unsafe distance, the higher the risk of infection. The duration factor in the study conducted by Su et al (2021) against pedestrians who are at an unsafe distance is also an important factor that must be taken into account. To describe the degree of gathering of pedestrians in public spaces, Su et al (2021) defines the concept of a gathering group.…”

This research aims to see an overview of ecotherapy-based activities as a form of intervention in the design of urban green spaces during the pandemic. Ecotherapy is a combined approach of socio-ecological strategy that promotes mental health, through community participation and empowerment. The ecotherapy-based activities include horticultural therapy such as gardening and physical therapy such as sports activities. The research method is a qualitative method through case studies. The case study was carried out at two locations of Taman Maju Bersama which in 2020 had conducted a Focus Group Discussion (FGD) process at the planning stage. The impact of the COVID-19 virus outbreak presents an opportunity to integrate a public health perspective into the concept of urban green space design standards. This is an opportunity to improve urban green space design standards that need to be considered by the Jakarta Provincial Government in the future. Some considerations should be included: 1) the opportunity to improve urban green space on a neighborhood scale, 2) the potential for an ecotherapy approach, especially on spatial program interventions in urban green spaces design, 3) consideration of health protocol policies for handling COVID-19, such as a new interpersonal physical distance limit in urban public spaces.

“… Sun and Zhai (2020) addressed two crucial indices for quantitatively evaluating social distancing and ventilation effectiveness in preventing transmission of respiratory disease infection like COVID-19. Su et al (2021) proposed a visual social distancing method in urban public spaces that considers both Euclidean distance between tracking objects from a static perspective and Frechet distance between trajectories to estimate and analyze the social distancing. Fu and Zhai (2021) applied the geographically and temporally weighted regression model to examine the association between conventional social vulnerability indicators and social distancing in New York City.…”

The ongoing COVOD-19(SARS-CoV-2) outbreak has had a devastating impact on the economy, education and businesses. In this paper, the behavior of an epidemic is simulated on different contact networks. Herein, it is assumed that the infection may be transmitted at each contact from an infected person to a susceptible individual with a given probability. The probability of transmitting the disease may change due to the individuals' social behavior or interventions prescribed by the authorities. We utilized simulation on the contact networks to demonstrate how seesaw scenarios of lockdown can curb infection and level the pandemic without maximum pressure on the poor societies. Soft scenarios consist of closing businesses 2, 3, and 4 days in between with four levels of lockdown respected by 25%, 50%, 75%, and 100% of the population. The findings reveal that the outbreak can be flattened under softer alternatives instead of a doomsday scenario of complete lockdown. More specifically, it is turned out that proposed soft lockdown strategies can flatten up to 120% of the pandemic course. It is also revealed that transmission probability has a crucial role in the course of the infection, growth rate of the infection, and the number of infected individuals.
