This review compares SARS-CoV-1, MERS-CoV, Neo-CoV, and SARS-CoV-2 (COVID-19), highlighting their origins, genetic similarities, and infection mechanisms. Understanding these coronaviruses aids in developing effective treatments and prevention strategies.
Area of Science:
- Virology
- Infectious Diseases
- Public Health
Background:
- Coronaviruses, including SARS-CoV-1, MERS-CoV, Neo-CoV, and SARS-CoV-2 (COVID-19), are significant global health threats originating from bats.
- These viruses primarily target the respiratory system, causing widespread infections and mortality.
Purpose of the Study:
- To conduct a comparative analysis of the key characteristics of SARS-CoV-1, MERS-CoV, Neo-CoV, and SARS-CoV-2.
- To elucidate their structural features, origins, evolutionary paths, and infection mechanisms.
Main Methods:
- Literature review and comparative analysis of existing scientific data on coronaviruses.
- Examination of genomic sequences, receptor binding (ACE2), cellular tropism, and pathogenesis.
Main Results:
- While genetically distinct, SARS-CoV-1 and SARS-CoV-2 share significant genomic similarity (79%) and utilize the ACE2 receptor.
- MERS-CoV exhibits higher mortality due to its ability to lyse epithelial and immune cells.
- SARS-CoV-2 infection mechanisms and host cell interactions require further investigation.
Conclusions:
- Comparative insights into these coronaviruses are crucial for understanding their pathogenesis and severity.
- This review provides a foundation for exploring therapeutic strategies and preventive measures against coronavirus outbreaks.

Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...
