The 2019 Novel Coronavirus Outbreak - A Global Threat

Area of Science:

• Virology
• Epidemiology
• Public Health

Background:

• The 2019 Novel Coronavirus (COVID-19) emerged as a significant global health emergency.
• Previous decades have seen the emergence of novel coronavirus epidemics.
• Knowledge gaps persist regarding COVID-19 epidemiology, transmission, diagnostics, and management.

Purpose of the Study:

• To review the available evidence on COVID-19.
• To discuss transmission patterns, clinical features, and diagnostic approaches.
• To summarize current management strategies and future research directions.

Main Methods:

• Literature review of existing evidence on COVID-19.
• Analysis of epidemiological data and transmission dynamics.
• Evaluation of diagnostic tools and clinical presentation.

Main Results:

• COVID-19 presents a spectrum of illness, from mild to severe, with complications like ARDS and septic shock.
• Diagnostic suspicion is raised by imaging findings (bilateral ground glass opacity, consolidation) in a relevant clinical context.
• Poor prognostic factors include multilobular infiltration, lymphopenia, co-infections, smoking, hypertension, and age >60 (MuLBSTA score).
• PCR testing confirms diagnosis; management is primarily supportive with investigational antivirals.

Conclusions:

• Controlling COVID-19 necessitates international cooperation due to its high transmissibility.
• Standard infection control, vigilant screening, isolation of symptomatic cases, and quarantine of contacts are crucial.
• Further research is needed on management strategies, including the role of antivirals and steroids.
