Abstract
The SARS-CoV-2 Coronavirus disease, also known as the COVID-19 pandemic, has engendered the biggest challenge to human life for the last two years. With a rapid increase in the spread of the Omicron variant across the world, and to contain the spread of COVID-19 in general, it is crucial to rapidly identify this viral infection with minimal logistics. To achieve this, a novel plastic optical fiber (POF) U-shaped probe sensing method is presented for accurate detection of SARS-CoV-2, commonly known as the COVID-19 virus, which has the capability to detect new variants such as Omicron. The sample under test can be taken from oropharyngeal or nasopharyngeal via specific POF U-shaped probe with one end that is fed with a laser source while the other end is connected to a photodetector to receive the response and postprocess for decision-making. The study includes detection comparison with two types of POF with diameters of 200 and 500 µm. Results show that detection is better when a smaller-diameter POF is used. It is also seen that the proposed test bed and its envisaged prototype can detect the COVID-19 variants within 15 min of the test. The proposed approach will make the clinical diagnosis faster, cheaper and applicable to patients in remote areas where there are no hospitals or clinical laboratories due to poverty, geographic obstacles, or other factors.

Summary
Since the early 2020, world has faced tremendous challenges due to SARS-CoV-2Coronavirus disease, known as COVID-19 * (* Official names announced for the virus responsible for COVID-19 (previously known as “2019 novel coronavirus”). Since the early 2020, world has faced tremendous challenges due to SARS-CoV-2. The official name for the disease is coronavirus disease (COVID-19), and the virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), attacks the immune system and infects the main respiratory tract of the human body. There is evidence that COVID-19 patients suffer from one of the following symptoms: coughing, fever, loss of taste and smell, tiredness, fatigue, diarrhea, and flu [3]. Difficulty in breathing and loss of oxygen saturation are the most significant issues that COVID-19 patients suffer from day 3 to 8. The world has entered a stage in which the realization is present in society that we have to live with this virus and the only way is to take certain precautions in order to protect yourself from these issues
