Numerical comparison of dispersion of human exhaled droplets under different ventilation methods
Stratum ventilation has been proposed to accommodate elevated room temperatures recommended by several governments in East Asia for energy saving. One key issue in evaluating the performance of stratum ventilation is whether this air distribution method performs significantly different in person to person infectious diseases transmissions. Particle dispersion in a classroom under mixing ...

Shigellosis From an Interactive Fountain: Implications for Regulation
In July 2003, the authors investigated an outbreak of Shigella sonnei infections in Marion County, Oregon. Nineteen confirmed and 37 presumptive cases, mostly young children, were identified. A case-control study implicated play in an interactive fountain in a city park (matched odds ratio undefined; p < .002). The association was confirmed by a cohort study among local schoolchildren (RR ...

Schistosome Vaccine, Schistoshield - Case Study
Schistosomiasis is a major neglected tropical disease (NTD) of public health concern to a billion people. Currently an estimated 200 million are infected and an additional an estimated 800 million people are at risk of acquiring this disease in 74 countries. The disease carries high morbidity. Revised estimates of disability adjusted life years (DALYs) and recent calculations based on ...

Expert judgement and re–elicitation for prion disease risk uncertainties
Much uncertainty surrounds transmission of transmissible spongiform encephalopathies (TSEs) through blood and blood derived products. A first expert elicitation with 14 experts was conducted in March 2008, and a second re–elicitation involving 11 experts was held a year later in March 2009. Both expert groups were calibrated using a series of seed questions for which values are known, and then ...

`Facial Masking for Covid-19 — Potential for “Variolation” as We Await a Vaccine`
A new theory proposed by infectious disease specialists at UC San Francisco Dr. Monica Gandhi and Dr. George Rutherford in the New England Journal of Medicine claims that if you are infected with COVID-19 through a mask, the face covering can limit the severity of your symptoms. They note that masks reduce the number of viral particles in the air, which leads to a lower dose of the virus, if ...

Corey’s Story: First Patient Treated with BEAR® Implant Going Strong After Six Years
Before any new medical technology is approved for use by the U.S. Food and Drug Administration, a considerable number of courageous patients must first agree to participate in clinical trials of the new technology – without any data on potential success rates. For the BEAR® Implant, that brave patient was Corey Peak, a recreational athlete who tore his anterior cruciate ligament (ACL) ...

Examining Models of Chronic Obstructive Pulmonary Disease (COPD) and their Application in Other Disease Frameworks
The field of medical science has long utilized disease models, which are systems simulating the progression and expression of a disease, to better understand various illnesses. These models facilitate the study of disease pathology, identifying underlying mechanisms, and developing potential treatments. In the context of respiratory diseases, numerous models have been developed, with a prominent ...

Phoebe’s Story: A Cross-Country Journey to Repair a Torn ACL
Some patients go to great lengths to ensure they receive the best treatment for an injury — even if it requires traveling to the opposite side of the country. That was the case with Phoebe Anderson, a collegiate athlete at the University of California at Berkeley who suffered an ACL tear while playing rugby. Twenty-year old Phoebe and her mother, Larissa, learned about the BEAR® ...

Luna’s Story: Teen Trailblazer Becomes First BEAR Implant Patient in Connecticut
Very rarely does a high school student who aspires to study medicine get a first-hand opportunity to be a medical trailblazer. But 15-year-old Luna Martini stepped comfortably into that role when she became the first patient in Connecticut to receive a BEAR® Implant to treat her torn anterior cruciate ligament (ACL). A freshman at Farmington High School, Luna aspires to be a doctor herself ...

UbiBot Products Support Intelligent Hospital and Clinic Operation
Temperature as well as relative humidity can affect the airborne survival of viruses, bacteria and even fungi. As such, environmental control in hospitals is important because disease transmission from the aerosol or airborne infection is possible. Environmental exposure is a common hazard for organisms and throughout this can pass on from one host to another. Factors such as temperature, ...

How to Properly Clean Medical Devices
When it comes to medical devices cleanliness is crucial. All medical devices, whether they are disposable, implantable or reusable, must be cleaned during the manufacturing process to remove oil, grease, fingerprints and other manufacturing soils. Reusable products must also be thoroughly cleaned and sterilized between each use to avoid infecting patients or causing illness. Reaching the right ...

UVC helps cut heating costs in jails
If you think it’s hard to get HVAC money for schools and similar public buildings, there is a harder nut to crack: correctional facilities. It can be even more difficult to get additional funds appropriated to improve conditions in buildings where people are incarcerated. Compounding the problem, many correctional facility employees are in close proximity with the inmate community daily. ...

Why COVID-19 Might Not be the ‘Big One’ - and What We Can Do to Prepare
As vaccine rollouts take place in many countries around the world, it feels like the globe will soon be able to take a collective sigh of relief that this pandemic could nearly be over. However, the reality may not be so simple. Leading scientists including the chair of the WHO’s strategic and technical advisory group for infectious hazards expect that SARS-CoV-2 will become endemic, ...

Be a germ buster. Wash your hands.
Effective hand hygiene reduces the risk of meat contamination and the transmission of foodborne disease Clean hands are essential to health and effective handwashing is one of the simplest ways to prevent the spread of germs. Hand hygiene is particularly important in minimizing food safety risks along food animal chains, as there are many diseases that can be transmitted to humans from polluted ...

Measuring the uncertainties of pandemic influenza
It has become critical to assess the potential range of consequences of a pandemic influenza outbreak given the uncertainty about its disease characteristics while investigating risks and mitigation strategies of vaccines, antivirals, and social distancing measures. Here, we use a simulation model and rigorous experimental design with sensitivity analysis that incorporates uncertainty in the ...

Omicron and Covid-19 Testing: What Healthcare Providers Need to Know
As the SARS-CoV-2 omicron variant (B.1.1.529) rapidly became the dominant strain in South Africa in late 2021, public health officials around the globe recognized that a new, highly transmissible form of the virus was likely emerging.1,2 However, understanding the specifics of what was different about omicron remained to be seen. Beyond higher transmissibility, questions around disease ...

Bovine spongiform encephalopathy and variant Creutzfeldt-Jakob disease risk management in Belgium
Large imports of cattle and meat and bone meal from countries potentially affected by bovine spongiform encephalopathy (BSE) may have led to the BSE agent entering Belgium, and the occurrence of domestic BSE cases. The first case was confirmed in 1997. The ability to avoid amplification of incoming infectivity, as well as to reduce already circulating infectivity, was greatly improved in Belgium ...

Nipah virus glycoprotein structure suggests therapeutic strategies
Recent molecular discoveries have provided new details on how Nipah and Hendra viruses attack cells, and the immune responses that fight back against this attack. The findings point to a multi-pronged strategy for preventing and treating these deadly diseases. The study was published in Science recently. Both Nipah virus and Hendra virus are carried by indigenous bats in some parts of the ...

Shoe Sanitizing Stations for Hospitals
During an early 2020 study in Wuhan, China, the epicenter of the COVID-19 pandemic, researchers swabbed multiple surfaces at a healthcare facility to study aerosol and surface distribution. Around 50% of the samples from healthcare workers’ footwear contained genetic material from the SARS-CoV-2 virus. In addition, as medical staff walk around the ward, the virus can be tracked all over the ...
