Summary
This review details the viral, immune, and pro-thrombotic phases of SARS-CoV-2 (COVID-19) infection, explaining how these stages contribute to viral sepsis and organ injury.
Area of Science:
- Immunology
- Virology
- Pathophysiology
- Hematology
Background:
- SARS-CoV-2 infection, or COVID-19, can trigger severe immune dysregulation.
- Abnormal blood coagulation is a significant complication, leading to viral sepsis.
- Understanding these processes is crucial for effective patient management.
Purpose of the Study:
- To elucidate the distinct physiopathological mechanisms of each COVID-19 phase: viral, immune, and pro-thrombotic.
- To correlate these mechanisms with the development of organ injury.
- To inform targeted therapeutic strategies based on disease phase.
Main Methods:
- Review of existing literature on COVID-19 pathophysiology.
- Analysis of viral, immune, and coagulation pathways.
- Examination of organ-specific injury mechanisms.
Main Results:
- The viral phase is characterized by direct viral effects.
- The immune phase involves a dysregulated inflammatory response.
- The pro-thrombotic phase is marked by abnormal coagulation, contributing to sepsis and organ damage.
Conclusions:
- Distinct physiopathological mechanisms define each phase of COVID-19.
- These mechanisms are directly linked to viral sepsis and multi-organ injury.
- Tailored treatments targeting specific phases are essential for improving outcomes in COVID-19 patients.

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

630
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

1.7K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
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...

01:26Stages of Infection
64.4K
Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...
