Norovirus Outbreak Worsens at Olympics Though Athletes Unaffected Norovirus Outbreak Worsens at Olympics Though Athletes Unaffected

The number of people struck down by a virus causing vomiting and diarrhea at the Pyeongchang Winter Olympics has more than doubled to 86, though athletes remain unaffected, the Korean Centers for Disease Control and Prevention (KCDC) said.Reuters Health Information

Johne R Abstract Virus-contaminated frozen berries have been frequently identified as cause of foodborne disease outbreaks. To provide new tools for virus detection and characterization in berries, next generation sequencing (NGS) and reverse transcription-digital PCR (RT-dPCR) techniques were tested here with strawberries previously involved in a large-scale norovirus (NoV) gastroenteritis outbreak in Germany. By NGS, about 29 million sequence reads were generated, which mainly showed identities to sequences from the plant matrix and from the bacterial flora. Most abundant virus sequences originated from plant-sp...

In this study, a highly sensitive and selective electrochemical biosensor was fabricated for the detection of human norovirus using novel peptides as recognition elements. The electrochemical biosensor was fabricated by assembling of eight novel peptides separately on the gold electrode and investigated their efficiencies for sensing human noroviruses. Among eight peptides, NoroBP peptide coated onto the gold electrode exhibited a high binding affinity towards human noroviruses, resulting a progressive decrease in current signals with increasing concentration of human norovirus (0 – 105 copies/mL). As a result, NoroB...

ConclusionsThis is the first extensive phylogenetic study revealing the important events of NoV strains circulating in Seoul. Particularly, our study period from 2014 to 2016 was very dynamic with the emergences of the three main NoV strains (GII.17|2014_Kawasaki, GII.4|2016_Kawasaki194 and GII.3|Hu/3-28/2015/HNZZ/CHN) every year. We are sure that it is hard to detect above findings by simple conventional analysis. Our present study reports a future paradigm of the NoV molecular epidemiology, which might be highly valuable to track new strains and predict oncoming outbreaks.

  NEW YORK (WABC) -- More people are getting sick after eating McDonald's salads. Officials say the outbreak started in May and was caused by a parasite infection called Cyclosporiasis. The Centers for Disease Control and Prevention said it has now sickened 507 people in 16 states, including New York and Connecticut. Symptoms include diarrhea, vomiting, fever and body aches. So far, 24 people have been hospitalized. Read more at WABC. Related Article Norovirus Outbreak Can Spread to EMTs and Paramedics

More than 600 people said they got sick after eating at a Chipotle outside Columbus, Ohio, health officials said Monday. And they still don’t know what has caused it. The Delaware General Health District began investigating the restaurant, located in Powell, Ohio, on July 31 after it received numerous reports from patrons who ate there between July 26 and July 30. The location was briefly closed for an investigation. On Aug. 3, health officials put out an update saying that they had received nearly 700 inquires and had interviewed over 500 people. On Monday, they provided another update on Twitter saying that officia...

Abstract Human noroviruses (HNoVs) are primarily transmitted by the fecal-oral route, either by person-to-person contact, or by ingestion of contaminated food or water as well as by aerosolization. Moreover, HNoVs significantly contribute to foodborne diseases being the causative agent of one-fifth of acute gastroenteritis worldwide. As a consequence of globalization, transnational outbreaks of foodborne infections are reported with increasing frequency. Therefore, in this review, state-of-the-art information regarding molecular procedures for human norovirus detection in food as well common food processing techno...

Authors: Zhang L, Li X, Wu R, Chen H, Liu J, Wang Z, Xing Y, Ishaq HM, Wang J, Yu P, Xu J, Ma C Abstract An acute gastroenteritis outbreak occurred at a private college in June 2014 in northwest China. This outbreak involved two teachers and 629 students (range: 17-27 years, average 21.3 years). The main symptoms included non-bloody watery diarrhea, stomach ache, nausea, and vomiting, and the duration of illness ranged from 1 to 7 days. Eight of 18 water samples were disqualified. Thirty-four norovirus (NoV) RNA-positive samples were identified from 48 stool-related samples (genotyping results: 13 GII, 13 GI and 8 ...

In this study, we evaluated the distribution of coliphage densities to determine their efficacy as fecal indicators of enteric viruses, including noroviruses, in water samples collected from a shellfish growing area in Republic of Korea over a period of approximately 1 year. Male-specific and somatic coliphages in water samples were analyzed using the single agar layer method, and norovirus genogroups I and II, which infect mainly humans, were analyzed using duplex reverse transcription quantitative PCR. Male-specific and somatic coliphages were detected widely throughout the study area. Several environmental paramete...
