Telemedicine and smart systems techniques for COVID-19: a systematic review

Coronavirus 2019 (COVID-19) is a global pandemic, which has placed a significant challenge on the earth for health, climate, and human life. A critical study of the most used protocols to help physicians establish a reliable diagnosis, prevention, and treatment protocols are among the top targets for controlling and tracking COVID-19.

This paper presents a comprehensive analysis of COVID-19 with a wide range of viewpoints, such as related factors to COVID-19 as clinical characteristics, comorbidities (obesity, cardiovascular diseases), maternal and fetal, children, mental health, smoking, supply chain disciplines, vaccines, and therapeutics. Also, a comparison between the first wave of pandemic and the second wave is presented. Besides, the role of technologies in fighting against COVID-19 and the function of artificial intelligence, deep learning, and medical images for the analysis of pandemics are discussed in this paper. Finally, our survey results and comparison between it and other surveys are also illustrated at the end of the paper.
