This review examines strategies to control Coronavirus disease 2019 (COVID-19), including vaccines and therapeutics. It also addresses challenges posed by genetic variability in controlling the SARS-CoV-2 pandemic.
Area of Science:
- * Infectious Diseases
- * Virology
- * Immunology
Background:
- * Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, is a global pandemic with significant mortality.
- * The pandemic necessitated rapid development of vaccines, therapeutics, and drug repurposing strategies.
- * Understanding viral and host genetic factors is crucial for effective pandemic control.
Purpose of the Study:
- * To review current strategies for controlling COVID-19.
- * To assess the efficacy of vaccines, novel drugs, and repurposed medications.
- * To identify limitations of therapeutic approaches due to genetic variability.
Main Methods:
- * Comprehensive literature review of scientific publications on COVID-19.
- * Analysis of vaccine development and clinical trial data.
- * Evaluation of therapeutic strategies targeting viral replication and host immune response.
Main Results:
- * Multiple COVID-19 vaccine candidates have received authorization, with others in development.
- * Therapeutic strategies focus on inhibiting viral entry/replication and modulating immune responses.
- * Nanotechnology shows promise for enhancing drug efficacy against SARS-CoV-2.
- * Human and viral genetic variability present challenges for some control approaches.
Conclusions:
- * A multifaceted approach combining vaccines and therapeutics is essential for managing COVID-19.
- * Ongoing research is vital to overcome challenges posed by genetic variability.
- * Continued development and evaluation of novel and repurposed treatments are necessary.
Abstract:
Coronavirus disease 2019 (COVID-19), caused by the Severe Acute Respiratory Syndrome Coronavirus type 2 (SARS-CoV-2), is the largest pandemic in modern history with very high infection rates and considerable mortality. The disease, which emerged in China's Wuhan province, had its first reported case on December 29, 2019, and spread rapidly worldwide. On March 11, 2020, the World Health Organization (WHO) declared the COVID-19 outbreak a pandemic and global health emergency. Since the outbreak, efforts to develop COVID-19 vaccines, engineer new drugs, and evaluate existing ones for drug repurposing have been intensively undertaken to find ways to control this pandemic. COVID-19 therapeutic strategies aim to impair molecular pathways involved in the virus entrance and replication or interfere in the patients' overreaction and immunopathology. Moreover, nanotechnology could be an approach to boost the activity of new drugs. Several COVID-19 vaccine candidates have received emergency-use or full authorization in one or more countries, and others are being developed and tested. This review assesses the different strategies currently proposed to control COVID-19 and the issues or limitations imposed on some approaches by the human and viral genetic variability.
