Recognizing that crowded, high-traffic airports and airplanes have been implicated in respiratory disease transmission, we partnered with administrators of Raleigh Durham International Airport (RDU) conducting a pilot study aerosol surveillance for viruses at RDU. From January to March 2018 used NIOSH 2-stage samplers collect 150 min samples crowded areas Four (17%) the 24 were positive known pathogens including influenza D virus adenovirus. These results suggest feasibility employing...
This study aimed to evaluate environmental air sampling as an alternative form of active surveillance for respiratory pathogens in clinical settings. Samples were collected from three locations the Emergency Department at Duke University Hospital Systems October 2017 March 2018. Of 44 samples collected, 12 positive known including influenza A, D, and adenovirus. Results suggest bioaerosol may serve a complement Additionally, since viruses detected aerosol samples, our results that hospital...
<title>Abstract</title> <bold>Background</bold> Adenoviruses have caused epidemics among both humans and poultry in Pakistan. There is growing evidence that adenoviruses sometimes spillover to infect other species. In this pilot study, we sought study the distribution of circulating adenovirus types humans, animals several areas Pakistan.<bold>Methods</bold> From February 2019 March 2021, patients with influenza-like illness or pneumonia seven hospitals near Islamabad were invited...
In 2018, our team collected aerosols samples from five poultry farms in Malaysia. Influenza D virus was detected 14% of samples. One sample had an 86.3% identity score similar to NCBI accession number MH785020.1. This is the first molecular sequence influenza Southeast Asia a bioaerosol sample. Our findings indicate that further study role IDV necessary.
It is estimated that 780 million people do not have access to improved drinking water sources and approximately 2 billion use fecally contaminated water. Effective point-of-use treatment systems (POU) can provide with sufficiently reduced concentrations of pathogenic enteric microorganisms pose significant health risks consumers. Household (HWT) utilize various technologies physically remove and/or inactivate pathogens. A limited number governmental other institutional entities developed...
The World Health Organization (WHO) reports that two billion people worldwide lack access to safely managed water sources, including 1.2 who already have improved sources. In many countries, household point-of-use (POU) water-treatment options are used remove or deactivate microorganisms in water, but not all POU technologies meet WHO performance requirements achieve safe drinking water. To improve the effectiveness of technologies, use multiple treatment barriers should be as a way increase...
Abstract Modern day large-scale, high-density farming environments are inherently susceptible to viral outbreaks, inadvertently creating conditions that favor increased pathogen transmission and potential zoonotic spread. Metagenomic sequencing has proven be a useful tool for characterizing the microbial burden in both people, livestock, environmental samples. International efforts have been successful at pathogens commercial environments, especially swine farms, however it is unclear...
Several different types of constructed wetland systems are being used as decentralized treatment including surface-flow, subsurface-flow, vertical-flow, and hybrid systems. Archetypical have design strengths weaknesses, therefore it should be possible to combined (integrated) optimize a number important processes. This study provides comparative efficacy data for two integrated (IWTS) designed enhance medium strength wastewater generated from pilot-scale intensive fish farm. Results the...
The ability of SARS-CoV-2 viral surrogates like Phi 6 and animal coronaviruses to survive for long periods on meat fish products at cold temperatures emphasizes the need rigorous sustained food sanitation hygiene in harvest, transport, processing, distribution these foods.
Although pneumonia is a known cause of morbidity and mortality in Sarawak, Malaysia, the etiology epidemiology are not well described this equatorial region. Routine clinical diagnostics for at government hospitals Sarawak had historically involved only bacterial diagnostics. Viral were obtained through outside consultations.From June 15, 2017 to May 14, 2018, we collected nasopharyngeal swabs from 600 patients all ages older than 1 month hospitalized with Sibu Kapit Hospitals. Specimens...
Current and emerging legislation in North Carolina other regions calls for the enumeration of Clostridium perfringens as a surrogate indicator protozoan parasites various types waters. Past studies that have evaluated selective media detection this bacterium provided limited, conflicting, inconclusive results. In study, membrane filtration was used to enumerate C. culturable spores or total cells 19 samples untreated 25 partially treated wastewaters on 3 candidate media, Tryptose Sulfite...
Disease outbreaks can readily threaten swine production operations sometimes resulting in large economic losses. Pathogen surveillance farms be an effective approach for the early identification of new disease threats and mitigation transmission before broad dissemination among a herd occurs. Non-invasive environmental bioaerosol sampling could affordable conducting routine farms, providing additional tool farmers to protect their animals themselves from threats. In this pilot study, we...
The World Health Organization (WHO) estimates 2.1 billion people lack access to safely managed water. Cloth filtration is often employed in rural and developing communities of South Asia for point-of-use water treatment, but bacteria viruses are too small efficient removal by this method. Chitosan a biodegradable, cationic, organic polymer derived from the chemical treatment chitin that acts as coagulant flocculant contaminant microbes other particles water, thereby facilitating microbes....
Abstract Background Free text in electronic health records (EHR) may contain additional phenotypic information beyond structured (coded) information. For major events – heart attack and death there is a lack of studies evaluating the extent to which free primary care record might add Our objectives were describe contribution recording about myocardial infarction (MI), including subtype, left ventricular function, laboratory results symptoms; cause death. We used CALIBER EHR research platform...
Burkholderia pseudomallei infections are prevalent in Southeast Asia and northern Australia often misdiagnosed. Diagnostics neither sensitive nor rapid, contributing up to 50% mortality rate. In this 2018 pilot study, we enrolled 100 patients aged 6 months–79 years from Kapit Hospital Sarawak, Malaysia, with symptoms of B. infection. We used three different methods for the detection : a real-time polymerase chain reaction (PCR) assay, rapid lateral flow immunoassay, standard-of-care...
