Cellulitis: How long does it take to heal on legs? - Harvard Health

Image
Cellulitis is an infection of the deep layers of the skin. It develops when bacteria enter through a cut, bite, or wound — including tiny breaks in cracked, dry skin. Common skin-dwelling bacteria, Staphylococcus or Streptococcus, are the usual culprits. Although cellulitis can occur anywhere on the body, the most common location is the lower leg. Dr. Arash Mostaghimi, a dermatologist at Brigham and Women's Hospital and associate professor of medicine at Harvard Medical School, weighs in on new research that explores important questions about how long it takes to fully heal. What are the symptoms of cellulitis? The body's natural immune response to this bacterial invasion triggers a painful rash that appears red on lighter skin and dark purple on darker skin. The affected area also may be swollen and feel warm. How is cellulitis treated? The typical treatment is five to 10 days of antibiotic pil...

Typhoid fever - Nature.com

Image
Abstract Typhoid fever is an invasive bacterial disease associated with bloodstream infection that causes a high burden of disease in Africa and Asia. Typhoid primarily affects individuals ranging from infants through to young adults. The causative organism, Salmonella enterica subsp. enterica  serovar Typhi is transmitted via the faecal–oral route, crossing the intestinal epithelium and disseminating to systemic and intracellular sites, causing an undifferentiated febrile illness. Blood culture remains the practical reference standard for diagnosis of typhoid fever, where culture testing is available, but novel diagnostic modalities are an important priority under investigation. Since 2017, remarkable progress has been made in defining the global burden of both typhoid fever and antimicrobial resistance; in understanding disease pathogenesis and immunological protection through the use of controlled human infection; and in advancing effective vaccination programmes through s...

30 years after Jack in the Box scandal, food safety issues still underreported - Association of Health Care Journalists

In 1993, hamburgers contaminated with E. coli O157:H7, pictured above, sickened hundreds and killed four children. Photo by Janice Haney Carr/CDC Decades after fast food chain Jack in the Box served undercooked hamburgers , sickening 700 people and killing four children, lack of federal oversight of the nation's food supply is still causing illness and death. Seattle-based food safety advocate and trial lawyer Bill Marler, who became nationally prominent on food safety issues after representing families in the Jack in the Box case in 1993, sees many of the same issues today. "You might think, 'Oh, I haven't heard anything about this problem for a while, so I guess everything is okay,'" Marler said during a June 14 AHCJ webinar . "Well actually, it's because the government is not telling you that it is an ongoing problem."  "The mix of food causing problems may have changed, but the problems we have today are the problems we h...

Man eats raw chicken for 25 days – why isn't he sick? - The Conversation Indonesia

John (surname withheld) is an influencer from Florida who has gained notoriety by eating raw chicken for at least 25 days. He uses a blender to grind up the uncooked chicken (wing and breast) with flavourings, raw eggs and lettuce before drinking this chicken smoothie. Raw chicken and eggs have a significant infection risk from harmful bacteria such as salmonella and campylobacter, which can cause severe illness. Symptoms of food poisoning include fever, nausea, vomiting, diarrhoea and blood infections that, even in healthy people, can lead to hospitalisation and death. So why has John not fallen sick with food poisoning from such an unconventional and potentially deadly diet? John says that he has contacted doctors about the safety aspects of his raw chicken diet, which makes one wonder if prophylactic antibiotics were advised to protect him from infection. Even if not, John, like all humans, has innate protective mechanisms against food poisoning. The stomach has highly a...

Call for data on foodborne outbreak investigations for source attribution on foodborne pathogens - World Health Organization (WHO)

Background In 2015, WHO estimated that unsafe food causes 600 million cases of foodborne illnesses and 420 000 deaths annually. 1  Many of these cases are due to foodborne disease outbreaks. For example, in the 2018–2019 biennium globally, the FAO/WHO International Food Safety Authorities Network (INFOSAN) 2  responded to 162 international food safety events, and the biological hazards were responsible for the largest number of these events. WHO is currently estimating global foodborne disease incidence, mortality and disease burden in terms of disability-adjusted life years (DALYs), with an aim to report the updated estimates by 2025. One of the objectives is to estimate the proportion of the burden of foodborne diseases that is attributable to food transmission and to specific foods. Outbreak data is required as one of the key information sources to analyse pathogens that cause outbreaks, enabling to derive estimates of attribution to specific foods. Outbreak analys...

Nemis Technologies unveils N-Light Salmonella Risk Test - Food Safety News

Image
— ADVERTORIAL — Nemis Technologies AG, a pioneering force in the field of pathogen detection, has unveiled the groundbreaking N-Light™ Salmonella Risk indicator test, marking a significant leap in real-world environmental monitoring in food processing facilities. The study, conducted in collaboration with Łukasz Richter, Product Manager at NEMIS Technologies AG, sheds light on the challenges associated with Salmonella detection and the critical importance of addressing these issues promptly. Salmonella in food processing facilities: An ongoing challenge Salmonella, a bacterial pathogen notorious for causing foodborne illnesses, poses a constant threat in food processing facilities. The prevalence of Salmonella varies based on factors such as the type of food processed, adherence to hygiene practices, and the efficacy of safety management systems, including Hazard Analysis and Critical Control Points (HACCP). In an exclusive interview with Richter, a seasoned scientist with a ba...

Salmonella Infections in Children - HealthyChildren.org

By: Robert W. Frenck, Jr., MD, FAAP Salmonella bacteria cause more than a million infections each year in the United States. Most often, people get sick after eating food contaminated with Salmonella . Their symptoms usually include diarrhea, fever and stomach cramps. Salmonella illness can sometimes be severe enough to require a hospital stay. Here's what families need to know about Salmonella , how to recognize symptoms of infection and how to prevent it. Learn about recent Salmonella outbreaks here. Who is most at risk from Salmonella ? Infections occur most often in infants and children younger than 4 years because their immune systems are still developing. Babies who are not breastfed are also more likely to get sick from Salmonella . Infants may be exposed to Salmonella if they eat contaminated food or come into contact with contaminated surfaces or sick family members. Elderly people and those whose immune systems are weakened from cert...

Stomach Flu (Viral Gastroenteritis): How Long It Lasts - Health.com

Image
The stomach flu, medically known as viral gastroenteritis, may last two days to up to two weeks, depending on what stomach virus you have. Norovirus, one of the most common stomach viruses, usually resolves within a couple of days. Other viruses—such as adenovirus or rotavirus—may give you a stomach bug for a week or longer. The influenza virus does not cause the stomach flu, despite the name. Still, the stomach flu can feel just as bad, or worse, than the flu as it can cause diarrhea, nausea, stomach cramps, and vomiting. Read on to learn how long viral gastroenteritis typically lasts in adults. Boy_Anupong / Getty Images The stomach flu, or viral gastroenteritis, is a type of intestinal infection that presents with mostly GI symptoms. It may be caused by a number of viruses but not influenza viruses as the term "stomach flu" suggests. Viral gastroenteritis is also a self-limiting disease. In other words, you will likely recover on your own w...
