Background: SARS-CoV-2 is the virus that causes COVID-19. Some people who recover from COVID-19 have symptoms that last long after the active infection ends. This is called long COVID. Sometimes, long COVID can affect the nerves and cause problems with sleep, thinking, the senses, and movement. Researchers want to find out whether people with long COVID have retained inactive remnants of SARS-CoV-2 in their bodies. Objective: To collect tissue samples to see if people with long COVID have remnants of SARS-CoV-2 in their bodies. Eligibility: People 18 years or older who have recovered from COVID-19, both with and without neurologic symptoms. Design: Participants will have 2 to 4 inpatient or outpatient visits over 4 months. Each visit will last 4 to 5 days. Participants will be screened to make sure it is safe to collect tissue samples from their body. They will have a physical and dental exam. They will have imaging scans and a test of their heart function. They will complete questionnaires about their health. They will give blood, urine, saliva, and stool samples. Their sense of taste and smell will be tested. Tissue samples will be taken from the digestive tract, lungs, colon, skin, muscle, lymph nodes, nasal passages, and mouth. Participants may be numbed or sedated for some of the procedures. Swabs will be used to collect cells from inside the mouth and nose. Participants will undergo lumbar puncture. A thin needle will be inserted into their lower back to draw out a sample of the fluid around their spinal cord. Participants will have follow-up phone calls after each clinic visit.
PASC Post Acute Sequelae of COVID-19
Study Description: It has been demonstrated that remnants of the SARS-CoV-2 virus remain after the resolution of the acute infective period. It is not known if these viral remnants interact with host tissues in the development and maintenance of the Post-Acute Sequelae of COVID-19 (PASC)/Long COVID. Better understanding of how torecover and characterize SARS-CoV-2 viral remnants from humans is a valuable first step in understanding the health impact that they may have on humans. This study will focus on the recovery and characterization of SARS-CoV-2 remnants from multiple organ sites of individual volunteers with persistent neurological complications from SARS-CoV-2 (Neuro-PASC) and volunteers those who have recovered from a SARS-CoV-2 infection (RV). Objectives: * Primary Objective: --To determine where remnants of SARS-CoV-2 virus can be recovered in persons with neuro-PASC and RVs. * Secondary Objectives: * To characterize the biochemical nature of SARS-CoV-2 recovered viral remnants (e.g. proteins, nucleic acids). * To determine if there are quantitative differences in recovered SARS-CoV-2 proteins between neuro-PASC and RV participants. * To determine if there are quantitative differences in recovered SARS-CoV-2 nucleic acids between neuro-PASC and RV participants. Endpoints: This is an exploratory cross-sectional protocol to determine whether the presence or absence of viral remnants can be detected in a range of human tissues. Hence, tissue-specific detection of viral remnants is the primary end point. Secondary endpoints will characterize and quantify the remnants to allow group comparisons between neuro-PASC and RV participants.
