Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will evaluate the correlation between the symptomaticity, Ct value, laboratory biomarkers associated to COVID-19 and the disease progression in hospitalized patients and outpatients with SARS-CoV2 infection diagnosed by RT-PCR assay for nasopharyngeal swab specimens in a specialized laboratory at Medellin,Colombia.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

After being informed about the study, all patients giving written informed consent will undergo a serial of test related to COVID-19. Rh and blood type will be obtained using the Colombian ID card or official document.

All symptomatic and asymptomatic COVID19-positive patients will be evaluated for a period of 4 weeks at three different times of the study. In a single time, the mitochondrial DNA will be measured, and the variability in the CT value, hemogram, cytokine levels, ratio of CD4 + / CD8 + lymphocytes, levels of dehydrogenase lactate, ferritin and D-dimer, antibodies IgG and IgM, will be measured on day 5, day 14 and day 28. In addition, spike S protein sequencing and growing the virus in cell culture that meet specific criteria will be performed. A physician will do clinical follow up through the period of the study for each patient.
