Viral Infections in Healthy and Immunocompromised Hosts
Background Viral infections are an important cause of illness and death in hospitalized patients as well as outpatients. New strains of viruses may appear and infect both healthy people and those with weak immune systems. A better understanding of these new virus strains (such as SARS-CoV-2, the virus that causes …
Genetic Evolution of Arboviruses in New Caledonia Between 1995 and 2024 and Impact of Wolbachia
Arboviruses, diseases transmitted to humans by the bite of an insect vector, are a major public health problem, especially in tropical and sub-tropical countries. A promising strategy aimed at blocking the circulation of arboviruses is to release Aedes aegypti mosquitoes carrying the endosymbiotic bacterium Wolbachia. In 2019, the Wolbachia strategy …
Evaluation of the Effectiveness and Impact of Nirsevimab Administered as Routine Immunization
A longitudinal observational study based on routinely collected data on hospital and health care use for RSV infections will be undertaken. The Galician public health registries will be used for data collection including baseline information and follow-up data. Historical data will be retrieved for comparison purposes. The study aims to …
Real-World Effectiveness of Perinatal RSV Immunoprophylaxis
The purpose of this study is to continue evaluating how well the RSV vaccines work as they are currently being used in routine clinical practice. Some of the questions that the investigators hope to answer with this study are: 1) What is the overall effectiveness of these vaccines? 2) How …
Multi-Center Molecular Diagnosis and Host Response of Respiratory Viral Infections in Pediatric Transplant Recipients
The participants are being asked to take part in this clinical trial, a type of research study, because the participants are scheduled to receive or have recently received a hematopoietic cell transplant (HCT) or a solid organ transplant (SOT). Primary Objective To determine if pre-transplant screening for respiratory viral load …
The Natural History of Severe Viral Infections and Characterization of Immune Defects in Patients Without Known Immunocompromise
Background Infections caused by viruses are common causes of illnesses: the common cold, many ear infections, sore throats, chicken pox, and the flu are caused by different viruses. Usually, these illnesses last only few days or, at most, a few weeks. Some virus infections like influenza are cleared from the …
REVIVe: Frailty, Rehabilitation, and Outcomes in Critically Ill Adult and Pediatric Survivors of COVID-19 or ARI
Background: Many adults and some children with COVID-19 or acute respiratory infection become critically ill and need advanced life support in the Intensive Care Unit (ICU). Frailty is a medical condition of reduced function and health. Adults with frailty have a lower chance of surviving critical illness. The investigators are …
Specimen Collections From Participants With HIV Infection, KSHV Infection, Viral-Related Pre-malignant Lesions and Cancer
BACKGROUND A number of important scientific advances can be made through the study of blood, bone marrow, tumor, or other tissue samples from patients with HIV infection, infection with Kaposi s sarcoma associated herpesvirus (KSHV), infection with other oncogenic viruses, or cancer. This protocol provides a mechanism to affect a …
Surveillance and Tracking the Outcomes of Chronic Latent EBV Infection
Immunocompetent subjects with high load of Epstein-Barr virus DNA (EBV-DNA) in peripheral blood will be enrolled and prospectively followed up to track the natural histories of the chronic high load of EBV virus. The primary goal of this study is to explore the association of peripheral high load of EBV …
Determinants of SARS (Severe Acute Respiratory Syndrome)-COV2 (COVID-19) Persistence After Convalescence
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 …
