Insights

The Coronavirus Disease 2019 (COVID-19) pandemic, caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), has led to a global health emergency. This article reviews COVID-19 trends, epidemiology, and control measures for global epidemic prevention.

Area of Science:

  • Epidemiology
  • Infectious Diseases
  • Public Health

Background:

  • The world has experienced three major coronavirus outbreaks in the last two decades.
  • Coronavirus Disease 2019 (COVID-19), caused by SARS-CoV-2, emerged in Wuhan, China, and rapidly became a global pandemic.
  • As of March 17, 2020, COVID-19 caused over 179,000 cases and 7,400 deaths globally, with no approved treatment or vaccine.

Purpose of the Study:

  • To summarize the worldwide epidemic trend of COVID-19.
  • To discuss the epidemiological characteristics of SARS-CoV-2.
  • To review prevention and control measures for global epidemic management.

Main Methods:

  • Review of worldwide epidemic data for COVID-19.
  • Analysis of epidemiological characteristics of SARS-CoV-2 transmission.
  • Compilation of current prevention and control strategies.

Main Results:

  • COVID-19 spread rapidly across 163 countries, causing a major public health emergency.
  • The virus, SARS-CoV-2, originated in bats and exhibits efficient human-to-human transmission.
  • A global mortality rate of 4.1% was observed among confirmed cases.

Conclusions:
