Coronaviridae family member, SARS-CoV-2, causes the COVID-19 pandemic. This review details its transmission, disease mechanisms, symptoms, and control strategies.
Area of Science:
- Virology
- Infectious Diseases
- Molecular Biology
Background:
- Microorganisms, including viruses, are ancient life forms.
- Viruses are obligate intracellular parasites with diverse families like Retroviridae and Coronaviridae.
- Viruses can cause significant human diseases, such as HIV-AIDS and the current COVID-19 pandemic.
Purpose of the Study:
- To review the transmission dynamics of SARS-CoV-2.
- To elucidate the molecular mechanisms of SARS-CoV-2 pathogenesis.
- To summarize clinical manifestations and control strategies for COVID-19.
Main Methods:
- Literature review of scientific databases (PubMed, Google Scholar).
- Information synthesis from reputable health organizations (NIH, WHO, CDC, EMBL, USFDA).
- Data compilation as of May 1, 2021.
Main Results:
- SARS-CoV-2 transmission occurs through respiratory droplets and aerosols.
- The virus hijacks host cell machinery for replication.
- Clinical symptoms range from mild to severe, affecting multiple organ systems.
Conclusions:
- Understanding SARS-CoV-2 transmission and pathogenesis is crucial for effective control.
- Public health interventions and medical strategies are essential to mitigate the pandemic's impact.
- Ongoing research is vital for developing advanced diagnostics, therapeutics, and vaccines.

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...
