Understanding the three phases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, or COVID-19) pathogenesis is key to developing effective therapeutics and vaccines against this global health crisis.
Area of Science:
- Virology
- Immunology
- Pathology
Background:
- Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes COVID-19, a disease with significant global health and economic impact.
- The urgent need for effective therapeutics and vaccines necessitates a deep understanding of viral pathogenesis.
- Current understanding suggests a three-phase progression of COVID-19: pulmonary, proinflammatory, and prothrombotic.
Purpose of the Study:
- To elucidate the pathogenesis of COVID-19 by detailing virus-host interactions, pathogenic mechanisms, and clinical manifestations across its three phases.
- To present a comprehensive overview of therapeutic strategies currently in clinical trials for COVID-19, based on the proposed pathogenesis model.
- To provide an updated summary of COVID-19 pathogenesis and available treatment options.
Main Methods:
- Literature review of recent publications on COVID-19 pathogenesis.
- Analysis of virus-host interactions and pathogenic mechanisms in each phase.
- Compilation and explanation of therapeutic strategies and their modes of action.
Main Results:
- Detailed description of the pulmonary, proinflammatory, and prothrombotic phases of COVID-19 pathogenesis.
- Identification of key virus-host interactions and clinical manifestations for each phase.
- Overview of various therapeutic strategies and example drugs currently under investigation.
Conclusions:
- A clear understanding of COVID-19 pathogenesis provides the scientific basis for developing targeted drugs and vaccines.
- The three-phase model offers a framework for understanding disease progression and guiding therapeutic interventions.
- This review synthesizes current knowledge on COVID-19 pathogenesis and therapeutic options, aiding future research and clinical practice.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
COPD: Pathogenesis and Clinical Features
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
