This study seeks to determine whether the virus which causes COVID-19, SARS-CoV-2, isshed in the stools of patients who are infected.

This is a prospective observational registry of COVID-19 recovered patients who are nolonger symptomatic. This Registry is intended to serve as a pool of individuals that canparticipate in studies associated with serological testing, characterization of immunityand immune response, vaccine development, and convalescent plasma donors.

A phase II clinical trial will be carried out with the objective of studying the impactof the administration of Tocilizumab on the evolution of the acute respiratory distresssyndrome (ARDS) in patients with severe or critical SARS-CoV-2 infection. Due to the highmortality of severe forms of SARS-CoV-2 and for ethical reasons, a control arm will notbe included. Patients will be recruited by signing an informed consent and the baselinevariables of interest will be recorded. Tocilizumab will be administered in one or twodoses, depending on the case, and will be followed up for 30 days. The response totreatment, survival and evolution will be studied. Factors associated with improvement ofARDS and survival will be identified through multivariate analyzes. The results will becompared with those reported internationally.

Emergent experimental and anecdotal evidence has indicated that critically ill COVID-19patients demonstrate two patient sub-types (called phenotypes). In one group the diseaseprogresses slowly and patients have a low potential of developing mild respiratoryfailure, but in the other group, an exaggerated immune response(hyper-inflammation/cytokine storm) may be linked to the onset of precipitous respiratoryfailure, termed acute respiratory distress syndrome. This syndrome is responsible for alarge portion of COVID-19 associated mortality. Thus, determining links betweenhyper-inflammation and acute respiratory distress syndrome in COVID-19 patients is ofimmediate importance. Blood samples will undergo a number of analyses to help us tounderstand as much as possible about COVID-19. We will also study any differences inphysiologic and cytokine levels before and after patients are treated withimmunomodulatory therapies as part of clinical care in COVID-19 patients.

Background:People who get infected with COVID-19 have an unpredictable risk to worsen and die. Thismakes it hard to decide who can quarantine at home and who should be treated at ahospital. Researchers think the risk may be related to how a person s B and T cellsrespond to the virus. B and T cells are the major components of a person s immuneresponse. B and T cells responding to the virus with a favorable pattern may lead torecovery, and this favorable pattern may be helpful to establish. If people in a vaccinetrial get this same favorable pattern when responding to a vaccine, this may be a usefulearly signal that the vaccine will be successful.Objective:To examine how immune cells respond to COVID-19 infection.Eligibility:Adults ages 18 and older who have a confirmed or suspected COVID-19 infection or hadCOVID-19 in the past.Also, healthy donors with no suspected COVID-19 infectionDesign:Participants will be screened with medical record review.Participants will be tested with a research assay to determine who was infected withCOVID-19 and who was not. This test will be used to understand research results, not toadvise patients.Participants with active infection must be isolated, usually in a hospital.Other participants may give blood samples at NIH or at their local doctor s office orlab.Participants may give blood samples up to three times a week for a total of ten times,and may also give blood samples after starting a vaccine trial.Participants will be contacted by phone or email every 2 months for up to 2 years.

The purpose of the study is to confirm if BACTEK-R (MV130) provides clinical benefit insubject with mild pneumonia (CURB-65≤2) by COVID-19 admitted to the Hospital.

The etiological agent of the current pandemic is a (+)ssRNA virus. SARS-CoV-2 isinfecting thousands of people in the world with a fatality rate that varies from 0.1 to5% in affected countries, thereby causing enormous economic losses. Few antibiotics haveshown any efficacy in their combat, but have not yet proven adequate to stop the spreadof the disease, nor are there any approved vaccines at the moment. From experiments inplants ongoing infections by RNA viruses, using thermotherapy, which is the applicationof heat at a temperature between 35-43 °C, the investigators know that raising thetemperature affects the transcription of viral proteins due to the formation of small RNAmolecules that interrupt the replication process by grouping in specific regions of theRNA molecule, preventing and inhibiting transcription. These small molecules are calledsmall interfering RNAs (siRNAs). This feature has been used through thermotherapy inhumans to combat the rapid replication of cells (i.e. cancer cells), attack cellsinfected by RNA viruses, and in the treatment of some parasitic infections.There arevarious commercially available devices for thermotherapy use in humans; they are mainlybeing used to ease muscle pain. They work by increasing the temperature in the rangerecommended for thermotherapy in humans 39-43 ° C. Therefore, the investigators considerthis treatment modality can be used to aid in the elimination of SARS-CoV-2 from thehuman body, decreasing viral load, which could allow the immune system time for itscontrol and elimination.

Mental health disorders are common during pregnancy and the postnatal period, and canhave serious adverse effects on the well-being of woman and child. Every tenth woman hasdepressive symptoms and 5% suffer major depression during pregnancy. The consequences forglobal mental health due to the novel coronavirus disease, COVID-19, are likely to besignificant and may have long-term impact on the global burden of disease. Pregnant womenmay be particularly vulnerable due to partial immune suppression. Besides physicalvulnerability, the women could be at increased risk of mental health problems, such asanxiety, depression, and post-traumatic stress disorder (PTSD), due to social distancingleading to less support from the family and friends, and in some cases, partners notbeing allowed to be present during prenatal visits, labor and delivery. Furthermore, manypregnant women may feel insecure and worried about the effect of COVID-19 on their unbornchild, if the women get infected during pregnancy. Today, young urban women are used toutilizing internet services frequently and efficiently. Therefore, providing mentalhealth support to pregnant women via web-based support may be effective in amelioratingtheir anxiety/depression and reduce the risk of serious mental health disorders leadingto improved maternal and perinatal outcomes.

A team at the University of Manchester are developing a test that tcould be helpful indetecting immunity to the Coronavirus (which causes the COVID-19 disease) in participantswith inflammatory arthritis. It is based on a flu assay has already developed; the teamwill replace the flu antigen with a Coronavirus antigen to see if it is effective.This project aims to develop a test to see if people who have had the virus havedeveloped immunity to it. This could help to predict who might or might not get thedisease a second time, who should stay at home to be protected from potential infectionor who will not develop any symptoms, even if exposed to the virus.When vaccination trials against the Coronavirus will be launched, this test could alsohelp to see if the vaccine is effective.

The main objectives of this study are 1) to establish the prevalence of SARS-CoV-2 inasymptomatic healthcare workers (HCWs) in an early phase of community spread as well as2) to monitor the future spread of the disease by assessing serological responses toSARS-CoV-2 in symptomatic and asymptomatic HCWs over time and 3) to improve theassessment of the immune response and its protective effect as well as the assessment ofinfectivity of affected HCWs and 4) to evaluate the value and significance of antibodyformation and serological antibody tests and 5) to be able to evaluate possible futurepreventive and / or therapeutic approaches against SARS-CoV-2, e.g. to assess vaccinationeffects
