Present cum future of SARS-CoV-2 virus and its associated control of virus-laden air pollutants leading to potential environmental threat – A global review

Application of IoT in Healthcare: Keys to Implementation of the Sustainable Development Goals

“…There is a lack of financial resources and greater multidisciplinarity and contacts between health governance and technological research centers. [77,78,[139][140][141][142][143][144][145][146][147] 4…”

“…2021, 21, x FOR PEER REVIEW 16 of 39IoT Application Solutions[77,78,[139][140][141][142][143][144][145][146][147]:• Intelligent systems, sensors, IoT, technologically advanced medical devices, communications networks, etc., represent a significant improvement in the synergies between medical centers in vulnerable countries and advanced healthcare centers in developed countries.•In recent months, it has been proven that technological systems and IoT applications are of great importance in the research, application, and prevention of diseases and pandemics worldwide, when it comes to vaccine and drug manufacturing, logistics, population vaccination planning and management, data management, and patient monitoring at home, among other efforts.•Traffic accident prevention and control systems have an ally in technological systems and advanced IoT applications, for example, in user applications that inform and warn of vehicle congestion in cities and highways, accident warnings, alarm systems in adverse weather situations, among others.•Development of efficient and high-quality vaccines, where sensor applications, IoT, and intelligent systems play a great role. Technology, in all its fields, has a fundamental mission for the effective development and distribution of vaccines to the entire population, with applications to data management, including patient data, vaccination control, health and safety, among others.•In the area of air and soil pollution and the detection of chemical elements in the environment, there are multiple applications of sensors and intelligent systems that detect, transmit, manage, and prevent such problems.…”

COVID 19 – Possible interrelations with respiratory comorbidities caused by occupational exposure to various hazardous bioaerosols. Part II. Clinical course, diagnostics, treatment and prevention

“…Similarly, Felix-Arellano et al [94] reported that the worldwide incidence and risk of morbidity and mortality from COVID-19 increases with chronic and acute exposure to air pollution, particularly to particulate matter (PM 2.5, PM 10 ) and nitrogen dioxide. Mukherjee et al [95] expressed a view that the combined effect of both virus-laden particulate matter and gaseous pollutants can be synergistic and life-threatening, especially in highly populated areas, such as those existing in India.…”

“…The fine particulate matter (dust) may also contain other microbes and their toxins that may stimulate the disease, thereby acting as harmful bioaerosol. The above-mentioned facts indicate that for the prevention of COVID-19 spread, increased efforts for reducing air pollution are needed, which would also be beneficial for effectively combatting the devastating climate change [91,95,96].…”

“…In conclusion, elimination of particulate matter and smog as virus carriers, especially the most hazardous particles PM 2.5 , acting as carriers of droplet nuclei and microbes, is crucial for effectively combatting COVID-19 and other respiratory diseases. From the world perspective, the actions aiming to improve the global air quality by replacement of fossil fuels with renewable solar and wind energy, and reduction of industrial air pollution by installing the highefficient filters at industrial outlets, based on scrubbing technology, cyclone separation technology, electrostatic precipitation, baghouse filtering or mist separation [95], should be implemented by governing bodies, both at the national and international levels. This would certainly be beneficial for human health and the environment, as well as for mitigating the devastating climate changes.…”
