Abstract
Coronavirus disease-2019 (COVID-19) is a respiratory disease in which Spike protein from SARS-CoV-2 plays a key role in transferring virus genomic code into target cells. Spike protein, which is found on the surface of the SARS-CoV-2 virus, latches onto angiotensin-converting enzyme 2 receptors (ACE2r) on target cells. The RNA genome of coronaviruses, with an average length of 29 kb, is the longest among all RNA viruses and comprises six to ten open reading frames (ORFs) responsible for encoding replicase and structural proteins for the virus. Each component of the viral genome is inserted into a helical nucleocapsid surrounded by a lipid bilayer. The Spike protein is responsible for damage to several organs and tissues, even leading to severe impairments and long-term disabilities. Spike protein could also be the cause of the long-term post-infectious conditions known as Long COVID-19, characterized by a group of unresponsive idiopathic severe neuro- and cardiovascular disorders, including strokes, cardiopathies, neuralgias, fibromyalgia, and Guillaume-Barret's like-disease. In this paper, we suggest a pervasive mechanism whereby the Spike proteins either from SARS-CoV-2 mRNA or mRNA vaccines, tend to enter the mature cells, and progenitor, multipotent, and pluripotent stem cells (SCs), altering the genome integrity. This will eventually lead to the production of newly affected clones and mature cells. The hypothesis presented in this paper proposes that the mRNA integration into DNA occurs through several components of the evolutionarily genetic mechanism such as retrotransposons and retrotransposition, LINE-1 or L1 (long interspersed element-1), and ORF-1 and 2 responsible for the generation of retrogenes. Once the integration phase is concluded, somatic cells, progenitor cells, and SCs employ different silencing mechanisms. DNA methylation, followed by histone modification, begins to generate unlimited lines of affected cells and clones that form affected tissues characterized by abnormal patterns that become targets of systemic immune cells, generating uncontrolled inflammatory conditions, as observed in both Long COVID-19 syndrome and the mRNA vaccine.

Abstract
BACKGROUND: The predominant pattern of lung lesions in patients affected by coronavirus disease (COVID-19) disease is diffuse alveolar damage with massive thromboembolism similar as described in patients infected with severe acute respiratory syndrome coronavirus and Middle East respiratory syndrome coronaviruses. Hyaline membrane formation and pneumocyte atypical hyperplasia were frequent. Importantly, the formation of platelet–fibrin thrombi in small vessels was seen consistent with coagulopathy, which appeared to be a common feature in patients who died of COVID-19. However, many were the cases found with similar COVID-19 symptomatology though negative results from nasal-pharyngeal swab performed by reverse transcription-polymerase chain reaction (RT-PCR). This latter typology of patients, otherwise named COVID-like, showed analogous clinical signs with similar arterial blood gas, cell blood count and laboratory parameters, and same computed tomography (CT)-scan ground-glass opacities. Symptoms such as cough, fever, and difficulty breathing were highly similar as well. Both forms, COVID-19 and COVID-like, are primarily respiratory with multi-organ involvement and both revealed comparable incubation periods often with a rapid onset and unexpected decay.
CASE REPORT: In this brief paper, we described two cases regarding two deceased males, one confirmed COVID-19 (RT-PCR but not CT scan) and the second a COVID-like (negative for RT-PCR but positive to CT scan with ground-glass opacity) whom condition, disease patterns, and analysis were highly similar.
CONCLUSION: Improved investigation is mandatory, in which RT-PCR and CT scan procedures are completed by data from more detailed laboratory analysis, ABG analysis, BALF, and a deeper clinical assessment.
