ABSTRACT
As of 27 December 2021, SARS-CoV-2 has infected over 278 million persons and caused 5.3 million deaths. Since the outbreak of COVID-19, different methods, from medical to artificial intelligence, have been used for its detection, diagnosis, and surveillance. Meanwhile, fast and efficient point-of-care (POC) testing and self-testing kits have become necessary in the fight against COVID-19 and to assist healthcare personnel and governments curb the spread of the virus. This paper presents a review of the various types of COVID-19 detection methods, diagnostic technologies, and surveillance approaches that have been used or proposed. The review provided in this article should be beneficial to researchers in this field and health policymakers at large.
ABSTRACT
The entire globe is battling the novel coronavirus disease (COVID-19) outbreak, which has caused a downward spiral in many nations' economies, particularly in the higher education contexts. A growing number of universities have either postponed or cancelled academic activities. A few universities have intensified measures to prevent face-to-face interactions, intending to protect staff members and students from this highly contagious disease. This study investigates the COVID-19 impact on the higher education sector in Nigeria. Interview sessions involving seven lecturers across five universities in three geographical locations of Nigeria were conducted. The interview data were gathered using digital applications, such as Zoom cloud meetings and Skype, transcribed into a textual format, and further analysed. Six themes with corresponding sub-themes emerged from the study. In the final analysis, results revealed that COVID-19 negatively impacted several universities. This study presents opportunities for responding issues, problems and trends that are currently arising and will arise in the future due to the impact of the COVID-19 pandemic in the Nigerian higher education system.
