diff spores to tolerate disinfection at in-use and recommended active chlorine concentrations," lead study author Tina Joshi, PhD, associate professor in molecular microbiology at the University of Plymouth, said in a university press release. The study authors say the findings highlight an urgent need to review current C difficile disinfection guidelines. This indicates that scrubs and gowns could serve as vectors of C difficile transmission in hospitals. Although fewer spores were recovered from the fabrics than the liquid, the investigators still found that the scrubs and gowns retained the spores, and that the spores still survived treatment with NaOCL when it was applied directly to the fabric. The researchers then applied spores from the three C difficile strains onto patient gowns and surgical scrubs and treated them with NaOCL. Spore recovery was reduced for one of the strains, but examination of spores from all three strains showed no changes to the outer spore coat and no significant reduction in spore viability, indicating a tolerance to the disinfectant. Three different strains of C difficile were exposed to NaOCL at concentrations of 1,000, 5,000, and 10,000 parts per million (PPM) for 10 minutes. While chlorine-releasing agents are used in the disinfection of fluid spills, blood, and feces in UK hospitals, recent studies have found signs of emerging sporicidal resistance. C difficile is the leading cause of healthcare-associated diarrhea, and causes an estimated 29,000 deaths in the United States and 8,382 in Europe each year. The study, conducted by researchers at the University of Plymouth and published in the journal Microbiology, examined the effect of clinical concentrations of sodium hypochlorite disinfectant (NaOCL) on C difficile spores, which can survive on hospital surfaces for months. "The point is we need information."Ī new study by researchers in the United Kingdom shows that a chlorine-based cleaner used on surfaces in UK hospitals is ineffective against Clostridioides difficile bacteria. She also said respiratory syncytial virus, COVID-19, and flu could be contributing factors. She added that China has already reported a Mycoplasma pneumonia surge, but the current outbreaks could be anything. On Twitter (X) today, Krutika Kuppalli, MD, an infectious disease physician who is with the WHO's Health Emergencies Program, said it's possible that China could be seeing a surge in respiratory infections as other countries did their first winter after lockdowns lifted. The illness can spread in crowded settings, including schools and college residence halls. In children, the infection resembles a chest cold. US Centers for Disease Control and Prevention (CDC) background information on Mycoplasma pneumoniae infection notes that the bacterium typically causes mild respiratory infections that can sometimes lead to serious illnesses that can require hospitalization. Some observers speculate the outbreak could be caused by Mycoplasma pneumoniae, commonly known as "walking pneumonia." FluTrackers, an infectious disease news message board, has been tracking reports of overwhelmed pediatric hospitals and clinics and Mycoplasma pneumonia since the beginning of summer. Reports also say the pneumonia outbreaks have led to school cancellations and some illnesses in teachers. The media reports reference swamped pediatric hospitals in multiple locations, including Beijing and Liaoning, which is nearly 500 miles away. But reports of a spike in pneumonia cases in China are eerily similar to early reports of a mystery pneumonia outbreak in late 2019 in Wuhan, which heralded the emergence of COVID-19.Ĭhildren's main symptoms are high fever, with some kids developing pulmonary nodules. So far, there is no indication that the infections are deadly. An undetermined pneumonia outbreak in China is hitting children hard, with media reports describing overwhelmed children's hospitals in multiple locations, according a post on ProMED Mail, the online reporting system of the International Society for Infectious Diseases.
