Area of Science:
- Virology
- Mathematical Biology
- Control Theory
Background:
- Epidemiological models dominated COVID-19 research, neglecting viral replication dynamics.
- Understanding human viral replication is crucial for developing effective antiviral treatments.
Purpose of the Study:
- To characterize validated mathematical models of SARS-CoV-2 replication in humans.
- To analyze the dynamic characteristics and equilibrium stability of the viral system.
- To identify critical conditions for reducing SARS-CoV-2 load in hosts.
Main Methods:

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...

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...

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...
