Diagnosing COVID-19: Did We Miss Anything?

Area of Science:

• * Virology and Emerging Infectious Diseases
• * Public Health and Epidemiology

Background:

• * An unexplained pneumonia outbreak emerged in Wuhan, China, in late 2019.
• * The outbreak rapidly escalated, signaling a potential global health crisis.

Purpose of the Study:

• * To identify the causative agent of the novel pneumonia-like disease.
• * To characterize the newly discovered pathogen.

Main Methods:

• * Collection of patient samples exhibiting pneumonia-like symptoms.
• * Application of unbiased sequencing techniques.
• * Isolation of the pathogen using human airway epithelial cells.

Main Results:

• * Discovery of a novel coronavirus, SARS-CoV-2 (initially named 2019-nCoV).
• * Identification of the virus responsible for the COVID-19 disease.

Conclusions:

• * The novel coronavirus SARS-CoV-2 is the etiological agent of COVID-19.
• * The findings underscore the importance of rapid pathogen identification during emerging disease outbreaks.
