Purpose of review: Human race is currently facing the wrath of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a highly transmittable and pathogenic RNA virus, causing coronavirus disease 2019 (COVID-19), the worst ever global pandemic. Coronaviruses (CoVs) have emerged as a major public health concern. Urgent global response to COVID-19 outbreak has been to limit spread of SARS-CoV-2 via extensive monitoring and containment. Various treatment regimens have been adopted to manage COVID-19, with known drugs and drug combinations used to decrease the morbidity and mortality associated with COVID-19. Intensive research on various fronts including studying molecular and structural aspects of these viruses and unraveling the pathophysiology and mechanistic basis of COVID-19 aimed at developing effective prophylactic, therapeutic agents and vaccines has been carried out globally.
Recent findings: No approved antiviral treatment except remdesivir exists for SARS-CoV-2 till date though novel drug targets have been identified. However, worldwide frantic and competitive vaccine development pharmaceutical race has borne fruit in the form of a number of promising candidate vaccines, out of which few have already received emergency use authorization by regulatory bodies in record time.
Summary: This review highlights the painstaking efforts of healthcare workers and scientific community to successfully address the COVID-19 pandemic-though damage in the form of severe illness, loss of lives, and livelihood has left a serious mark. Focusing on extensive research on various therapeutic options and antiviral strategies including neutralizing antibodies, potential drugs, and drug targets, light has been shed on various diagnostic options and the amazing vaccine development process as well.
