Dime La VerDAD: Verify, Debunk, and Disseminate

Dime la Verdad (Tell me the truth) will evaluate the use of storytelling by community health workers as a communication strategy to disseminate reliable health information on social media and encourage informed decision-making in favor of recommended immunizations in communities with high morbidity and mortality due to respiratory virus infections. Dime La Verdad is an innovative social media capacity-building program based on theoretical frameworks related to health communication that empowers community health workers to disseminate reliable information about respiratory virus protection strategies through the use of personal narratives on social media. The proposed work will use a rigorous stepped wedge design to 1) deliver a scalable program of science communicators using an adapted curriculum grounded in principles of health communication, 2) evaluate how diffusion of health messaging is perceived on social media, and 3) discern how use of personal narratives to enhance science communication can encourage informed decision-making to promote evidence-based immunization practices and improve health outcomes.

Wells and Enteric Disease Transmission

Approximately 40 million people in the US are served by private, and frequently untreated, wells. Our best estimate is that 1.3 million cases of gastrointestinal illnesses (GI) per year are attributed to consuming water from untreated private wells in the US, but in reality, there are no robust epidemiological data that can be used to estimate cases of GI attributable to these sources. We propose the first randomized controlled trial (RCT) to estimate the burden of GI associated with private well water. We will test if household treatment of private well water by ultraviolet light (UV) vs. sham (inactive UV device) decreases the incidence of GI in children under 5. We will also examine the presence of viral, bacterial, and protozoan pathogens in stool and well water from participants. These data will fill a knowledge gap on sporadic GI associated with federally-unregulated private water supplies in the US.

Study to Assess the Safety and Efficacy of ZX-7101A for Oral Suspension in Chinese Pediatric Participants 2 to 11 Years of Age With Influenza

The goal of this phase III study is to learn if ZX-7101A for oral suspension works to treat uncomplicated influenza in Pediatric Participants aged 2 to 11 years. The main question it aims to answer is: What medical problems do participants have when taking drug ZX-7101A for oral suspension or Oseltamivir phosphate for oral suspension? Researchers will compare drug ZX-7101A for oral suspension to active comparator: Oseltamivir phosphate for oral suspension to see if drug ZX-7101A for oral suspension works to treat uncomplicated influenza in Pediatric Participants aged 2 to 11 years.

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 predicts RVI within 1- year post-transplant among survivors. Secondary Objectives: * To develop and validate a classifier based on pre-transplant immunological profile predictive of developing an acute respiratory viral infection (aRVI), with RSV/PIV3/HMPV/SARS-CoV-2 through one-year post-transplant among survivors. * To develop and validate a classifier based on Day +100 post-transplant immunological profiles predictive of developing an acute respiratory viral infection (aRVI),with RSV/PIV3/HMPV/SARS-CoV-2 through one-year post-transplant among survivors .

Effect of Respiratory Virus Infection on EmeRgencY Admission Study (EVERY Study)

Study design is multicenter prospective registry study. Participants are consecutive (non-selected, a sequential registration) patients admitted from emergency rooms of participating hospitals who meet the eligibility criteria. The primary objectives are to estimate the prevalence of and risk factors for RS and other respiratory virus infection and their effect on hospital course in patients with any respiratory symptom who admit from emergency room using a multicenter prospective registry study. The primary target virus is RS virus and the secondary target viruses are respiratory virus and other microorganisms measured by FilmArray 2.1.

Vitamin D Supplementation in the Prevention and Mitigation of COVID-19 Infection

The purpose of this study is to evaluate how useful vitamin D supplementation is in reducing the severity of COVID-19 symptoms and the body's inflammatory and infection-fighting response to COVID-19. Individuals ≥50 years of age and older who are tested for COVID-19 and negative will be randomized (like flipping a coin) to either daily high dose vitamin D supplementation (6000 IU vitamin D3/day) vs. standard of care. Those individuals ≥50 years of age or older who test positive for COVID-19 at baseline will be randomized to bolus vitamin D (20,000 IU/day for 3 days) followed by high dose (6000 IU vitamin D/day) vs. standard of care for 12 months. All participants will receive a multivitamin containing vitamin D.
