Covid-19: current knowledge, disease potential, prevention and clinical advances

Area of Science:

• * Infectious Diseases and Public Health
• * Global Health Security
• * Viral Pathogenesis

Background:

• * The COVID-19 pandemic, originating in Wuhan, China in 2019, has caused widespread global disruption.
• * The outbreak exposed significant fragilities in established healthcare systems worldwide, despite advancements in science and technology.
• * Currently, no specific antiviral chemotherapeutic agents or vaccines are available to effectively curb the novel coronavirus disease.

Purpose of the Study:

• * To present a comprehensive review of the current status of COVID-19.
• * To detail the epidemiology, diagnostic methods, and therapeutic strategies for COVID-19.
• * To discuss the ongoing vaccine development and the broader socio-economic implications of the pandemic.

Main Methods:

• * Literature review of current research and clinical data on COVID-19.
• * Analysis of epidemiological trends and diagnostic advancements.
• * Evaluation of existing therapeutic agents and vaccine development progress.

Main Results:

• * Existing antiviral drugs (e.g., Remdesivir, Favipiravir, Ribavirin) and antimalarial agents (e.g., Chloroquine, Hydroxychloroquine) are being repurposed for COVID-19 treatment.
• * These repurposed drugs have shown clinical activity, offering some therapeutic options.
• * Significant global efforts are underway for rapid COVID-19 vaccine development.

Conclusions:

• * COVID-19 presents a substantial threat to global health and economic stability.
• * Repurposing existing drugs offers a temporary solution, highlighting the urgent need for effective treatments and vaccines.
• * The pandemic necessitates a re-evaluation of public health infrastructure and global preparedness for future infectious disease outbreaks.
