COVID-19, caused by SARS-CoV-2, has become a major global health crisis with no specific vaccine or antiviral drugs available. The rapid spread of the virus highlights the urgent need for effective therapeutic strategies. Understanding the disease pathology is crucial for developing targeted treatments.
A highly contagious coronavirus disease COVID-19 caused by a recently identified severe acute respiratory syndrome CoV-2 (SARS-CoV-2) initially detected in Wuhan, China has spread worldwide and become a major health crisis in the absence of specific vaccine or antiviral drugs. SARS-CoV-2 infection has resulted in overwhelming number of reported deaths. Unfortunately it is still spreading uncontrollably despite implementing stringent protective measures. Rapid development of effective therapeutic strategies for treatment and prevention of infection is crucially required. Although genomic characterization has assisted in unfolding various aspects of SARS-CoV-2 but development of specific antiviral drugs and vaccine against COVID-19 is still a worldwide challenge. Understanding the disease pathological course underlying the clinical manifestations of COVID-19 is imperative to identify the vital targets for drug development. SARS-CoV-2 uses angiotensin converting enzyme 2 (ACE2) receptor to enter the host cell and primarily target type II alveolar cells. COVID-19 disease progression is associated with distressed immune functions and hyper active inflammatory system leading to development of cytokine storm which is a vital factor involved in disease advancement. The current review elucidates the disease pathology and summarizes the possible therapeutic options to battle against COVID-19 on the basis of current state of understanding about SARS-CoV-2 pathogenic pathways and knowledge gained from previous SARS and MERS-CoV epidemics. Therapeutic strategies to treat and prevent infection as well as to suppress the disease progression to reduce severity and mortality rate is discussed. Drug candidates currently under consideration and undergoing clinical trials for COVID-19 treatment are highlighted.
