The 2019-2020 COVID-19 pandemic is the largest outbreak in recent history. It is not known how long after someone gets sick with COVID-19 and recovers that they can still infect other people. It is also not known how quickly people make antibodies against the virus, which help clear infection from the body. The investigators will enroll 300 people who had COVID-19 based on lab testing or confirmed exposure to participate. An additional 25 participants who have never tested positive for COVID and have not had the vaccine will be enrolled as negative controls. Participants will complete a survey at enrollment. The investigators will also collect blood, nose swab, saliva, stool, semen, and breast milk to test for the virus. The investigators will ask participants to complete a survey and give specimens up to 12 times over 24 months. This information will be used to study how long the virus can live in different parts of the body, antibody development, and post-infectious complications. The investigators hope that this information will allow medical and public health providers to make recommendations to better care for patients in the convalescent phase of COVID-19 infection.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a newly identified, highly contagious RNA virus causing respiratory infectious disease, Coronavirus Disease 2019 (COVID-19). Conjunctivitis has been reported as a rare finding of the disease, and preliminary studies showed that the virus RNA could be detected in ocular secretions using polymerase chain reaction (PCR) assays when conjunctivitis present. This study aims to estimate the proportion of SARS-CoV-2 associated conjunctivitis among patients with suspected viral conjunctivitis presented to the ophthalmology clinics of Wilmer Eye Institute during the COVID-19 pandemic. The investigators also aim to identify whether SARS-CoV-2 associated conjunctivitis is an isolated finding or an early sign of COVID-19.

The purpose of this study is to see if repeat bacillus Calmette-Guérin (BCG) vaccinations can confer a beneficial immune and metabolic effect on Type 1 diabetes. Published Phase I data on repeat BCG vaccinations in long term diabetics showed specific death of some of the disease causing bad white blood cells and also showed a short and small pancreas effect of restored insulin secretion. In this Phase II study, the investigators will attempt to vaccinate more frequently to see if these desirable effects can be more sustained. Eligible volunteers will either be vaccinated with BCG in a repeat fashion over a period of four years, or receive a placebo treatment. The investigators hypothesize that each BCG vaccination will eliminate more and more of the disease causing white blood cells that could offer relief to the pancreas for increased survival and restoration of insulin secretion from the pancreas. An additional adaptive trial for COVID-19 is also being conducted on these randomized double blinded type 1 diabetic subjects receiving BCG or placebo injections. An expanded study arm has been approved for repeat dosing of BCG in adult Type I diabetes.

The novel coronavirus SARS-CoV-2 infection, COVID, continues to rage throughout the world with 115,000,000 confirmed cases and over 2,500,000 deaths (as of Mar 3, 2021). This translates to millions of people surviving COVID19 infection. While the lungs are ground zero, COVID tears through organ systems from brain to blood vessels. We are now beginning to see people recover but complain of ongoing problems, including lingering cognitive problems, depression, and anxiety. We have brought together 2 laboratories with complementary techniques including psychological testing and neuroimaging methods togethers with markers in the blood that may signal damage in the brain. A close look at these problems is timely and imperative if we are to understand the pathophysiology of 'COVID brain' and prepare for downstream problems.

Persistent smell loss that can include diminished or distorted smell function is a common symptom of long COVID syndrome. There are limited treatment options for long COVID-related smell loss. This study aims to determine the efficacy of two at-home treatments, smell training and non-invasive trigeminal nerve stimulation. This study requires participants to conduct daily at-home treatment sessions, attend three in-person study visits at the MUSC Department of Psychiatry and Behavioral Sciences, and complete electronic questionnaires over the 12-week trial, and again at the six-month timepoint. Participants in this trial may benefit directly with an improvement in sense of smell. However, participation may also help society more generally, as this study will provide new information about long COVID-related smell loss and its treatment.

Preliminary evidence suggests that cognitive impairment is a common outcome experienced by individuals surviving Covid-19 (1-5). Cognitive impairment following Covid-19 which leads to critical illness is not surprising and perhaps even expected. However, significant cognitive deficits appear to be common even among individuals testing positive for Covid-19 who were never hospitalized. Questions exist regarding the mechanisms of the aforementioned cognitive impairment. The association between COVID-19 and brain dysfunction is not surprising since SARS-CoV has been found in the brain and because Coronaviridaes (CoVs) have been associated with central nervous system (CNS) diseases such as acute viral encephalopathy, acute disseminated encephalomyelitis, and multiple sclerosis (6-11).The possible brain entry routes for CoVs include either direct intranasal access to the brain via olfactory nerves or indirect access by crossing the blood-brain barrier (BBB) via hematogenous or lymphatic spread (9).

The general purpose of the study is to determine the change in immune responses in people with Post-Acute Sequelae of SARS-CoV-2 Infection (PASC) after vaccination. PASC is a disabling, heterogeneous condition in which people have persistent or emerging symptoms months after an initial SARS-CoV-2 infection, (the virus that causes coronavirus disease 2019, or COVID-19. Specifically, the purpose is to enroll participants suffering from moderate-to-severe PASC prior to vaccination and to measure participants' immune and symptom profiles both before and after vaccination. This study is primarily descriptive.

The Lucira COVID-19& Flu Test is a single use (disposable) RT-LAMP test kit intended for the simultaneous rapid in vitro qualitative detection and differentiation of SARS-CoV-2, Influenza A, and Influenza B viral RNA in anterior nasal swab specimens. The test consists of a nasal swab, a sample vial the nasal swab sample is placed in the sample vial, containing the sample buffer, and the test unit, which detects whether SARS-CoV-2, Influenza A, and Influenza B virus is present within the specimen during an acute infection. The Lucira test uses a proprietary, molecular based process to detect the presence of SARS-CoV-2, Influenza A, or Influenza B virus. The purpose of this study is to investigate the Lucira COVID-19 & Flu Test for the in vitro qualitative detection and differentiation of RNA from SARS-CoV-2, Influenza A, and Influenza B in nasal swab specimens from patients suspected of COVID-19 or Influenza A or Influenza B. The primary objective is to test at least 1000 self-collected nasal swab samples and to confirm the Lucira COVID-19 & Flu Test provides similar accuracy to a high complexity lab molecular diagnostic RT-PCR assay(s) with known high sensitivity for detecting SARS-CoV-2, Influenza A, and Influenza B virus.

This project aimed to test the efficacy of a telehealth-administered placebo without deception intervention on stress, anxiety, and depression related to the COVID-19 pandemic. Participants were randomized into two groups (open-label placebo vs. no-treatment control). All participants received information on the impact of COVID-19 on psychological health. Participants in the open-label placebo group were instructed to watch an informational video on the beneficial effects of placebos without deception, remotely interact with an experimenter, and take open-label placebo pills twice a day for two weeks. Participants in the no-treatment control group did not receive any intervention. Instead, participants met with an experimenter and reported on their psychological and physical health. The investigators predicted that the placebo without deception group would exhibit substantially reduced stress, depression, and anxiety compared to a no-treatment control group.
