The severe acute respiratory syndrome coronavirus (SARS-CoV-2), a novel coronavirus that is related to SARS-CoV-2 and the Middle East respiratory disease coronavirus, has spread widely, prompting the World Health Organisation to declare a pandemic. The disease caused by the SARS-CoV-2, known as COVID-19, has flu-like symptoms that can become serious and expose people to higher risk. At least 64,897,870 COVID-19 cases and 1,500,271 fatalities associated with it were reported globally as of December 3, 2020. SARS-CoV-2 is one of three highly virulent coronaviruses that pose a global threat to public health. The purpose of this study is to the most recent methods for diagnosing and treating COVID-19. Real-time reverse transcription-PCR (RT-PCR) is the testing technique that is most frequently used to identify SARS-CoV-2. We have outlined the most recent developments in conventional medicines for the treatment of COVID-19 to be examined, including vaccination, antiviral medications, such as remdesivir, chloroquine or hydroxychloroquine, favipiravir, and anti-SARS-CoV-2 monoclonal antibody treatment. The broad range of treatment strategies works to determine the most effective action. This study's objective is to explain the diagnostic and therapeutic approaches applied to COVID-19 patients. https://www.biotech-asia.org/vol20no4/review-of-covid-19s-current-development-in-therapeutic-and-diagnostic-techniques/ Antiviral drugs; Antiviral vaccines; Covid-19; Diagnostic methods
