In this article, Sun & Metzger (2014) propose the mechanism for influenza- induced predisposition to methicillin- resistant Staphylococcus aureus superinfection. They hypothesize that suppression of NADPH oxidase, an enzyme responsible for the production of intracellular reactive oxygen species during phagocytic bacterial killing plays a pivotal role to enhance susceptibility to secondary MRSA infection. They conduct a mouse model influenza infection experiment followed by S. aureus respiratory challenge to demonstrate impairment of innate antibacterial defense by influenza virus. They find high bacterial burden on influenza and MRSA- coinfected mice as compared to MRSA alone, which infer decreased bacterial clearance capability and survival
Ct returned from JPS with documentation stating to be diagnosed with Type B Influenza. Ct was removed form his Bunk - 112/63 per CD and moved upstairs to a single room - 224. Ct was issued new linen, towels, washcloths, water bottles, Clorox wipes, disinfectant, a roll of toilet paper, and was instructed to stay in his room until further instructions. Due to Ct's Flu diagnosis, Ct will have to have his meal(s) delivered to his room by the scheduled FMs.
potential pathogens and their particular tissue location. Rapid influenza antigen testing is completed by swabbing the nose, mouth or throat obtaining secretions for staining with fluorescent antibodies to identify the virus. This usually takes 1 to 3 hours for the determination of results whether a bacteria is positive or negative, so that the correct antibiotics can be prescribed. First a thin smear of bacteria on a clean slide that is covered with crystal violet stain for 1 minute. A wash is completed and iodine solution is added to the smear to enhance staining for 1 minute. Being rinsed again in water and then 95% ethanol for one minute. Washing the violet stain off will differentiate between the two types of bacteria. If the bacteria
Martha Quezada Kimmons AP World History March 05, 2018 The Influenza (DBQ) In 1918 a new and unknown virus emerged causing the Influenza pandemic to spread worldwide. It diffused from Asia to the Middle East, Europe, and Africa. The pandemic lasted until 1919 but its effects were very shocking to the population as it was so deadly it killed more than 50 million people and infected about 20% to 40% of the population.
Annually there are a number of children who contract the influenza during the influenza season that results in an increase in costs in pediatric office visits and antibiotic and other medications consumption and also in a significant increase in absences from school and work. Thus influenza vaccination of children can help reduce the number of visit to pediatric office, hospitalizations, and help prevent the spread of influenza in the wider community. Moreover vaccinating children is cost effective when considering all the cost of treatment for influenza and its complications. Therefore yearly vaccination of children with the inactivated influenza vaccine save parent money and time away from the pediatric clinic. Influenza vaccine does not
Natalie informed members that clarification has been provided where the Prevnar 13 will be given first then Pneumo23 vaccine. This is forthcoming for the next influenza season by Alberta Health in August 2016.
Influenza, also known as ‘the flu’, is a viral infection that tends to extent through societies between November and April every year, with a highest number of cases occurring in January and February. It is a respiratory illness that causes chills, high fever, body aches, and cough, but sometimes, its complications can be deadly. “About 5% of the population will contract the flu each year” (Influenza and your Health, 2017). Considering this, the “flu” is a very significant infection to study, characterized by specific symptoms, affects diverse age groups, and needs a vaccine protocol of which we must have knowledge to be prepared
A URI or Upper Respiratory Infection is also known as the common cold. There are several types of viruses that can contribute to a URI. When the body notices that there is a foreign virus, it begins to increase the mucus production, swelling in your nose which makes it hard to breathe, sneezing and coughing. The best way to prevent colds is by keeping away from other people that may already be sick, hand hygiene, sanitize your area throughout the day. Treatment for the common cold is simply based on what symptoms you have. Antibiotics cannot cure a cold. There are some medications that can help relieve symptoms but it will not make them go away.
The influenza pandemic of 1918-1919 impacted places throughout the world both negatively and positively. Often the reason for the major spread of pestilence was due to transportation of goods and people. This pandemic infected people worldwide, killing millions. Overall people responded to the pandemic in different ways through commitment to the task, consulting religion, avoiding contact with others, and the effort to raise public health awareness.
Claudia is a twenty year old junior currently attending the University of Nebraska-Lincoln. About a week ago Claudia went to the health clinic on campus to be checked out. She has been feeling ill with flu like symptoms including headache, fever, achy all over and being tired. She also disclosed that she has been treating a yeast infection with Monistat, an over-the-counter anti-viral cream with no relief. After answering some common questions asked by the doctor, such as “are you sexually active” and “how many partners have you had,” the doctor decided Claudia should be tested for a few sexually transmitted infections in addition to being tested for the flu. Test results were negative for everything except HIV. Devastated with the news
I think many can testify to being guilty of brushing off symptoms like a stuffy nose, and the feeling of fatigue as the common cold, treatable by over the counter drugs. We tend to ignore these minor signs of what could possibly be a very dangerous and severe viral infection, this respiratory infection being the influenza virus. Flu activity most often appears between the months of February and May, leading many to believe their symptoms might be caused by allergies. Although symptoms are very similar, the flu can cause epidemics with the deadly outcomes, as the common cold is just a nuisance for us.
Around 5 million people worldwide are affected annually by the influenza A virus (IAV), with infection resulting in severe morbidity and sometimes death. Although effective IAV vaccines exist, annual influenza epidemics occur due to its ability to quickly evolve new strains. Therefore, IAV remains a serious public health threat as evidenced by the recent pandemics involving swine H1N1 and avian H7N9. Thus, there is a vital need to develop more effective vaccines against influenza. Normally, vaccines function by priming the immune system to recognize a pathogen so that the body can more easily identify and eliminate it upon a second encounter. This protective immunity relies on receptors in the innate immune system such as the pattern recognition receptors (PRRs) Toll-like receptors (TLRs) and retinoic acid inducible gene I (RIG-I). In contrast, Nod-like receptors (NLRs) sense cellular damage as a result of infection and engage the inflammasome. Inflammasomes are multiprotein complexes that stimulate the secretion of inflammatory cytokines. Recent work by Pang et al. examined the relevance of host recognition of viral PAMPs versus virus-inflicted damage in linking innate recognition of IAV to adaptive immunity. Mediation of adaptive immunity to IAV is attributed to production of interleukin-1α (IL-1α) and IL-1β, cleavage products of the inflammatory cytokine IL-1. Pang et al. provided evidence that induction of an adaptive CD8+ T cell response did not depend on PRRs
Influenza A is a highly contagious infection of the respiratory tract that affects all ages. The infection is highest among children and the frequency of serious illness and death is greatest among older adults, over 65 years old. Influenza often is a self-limited disease, subsiding without therapy. It comonly occurs in outbreaks, mainly in the winter months.
Influenza testing is gathered to help diagnose an influenza infection and sometimes to help document and determine the presence of specific types and/or the strains of influenza causing the infections during the flu season. Routinely influenza cases are diagnosed without any form of testing done by the physician, especially during the absence of the flu season and knowledge the flu virus is evident in the community. Testing is also performed to monitor flu viruses that may be circulating in an area, the location of outbreaks, to look for new strains of viruses
According to History.com, a well-known historical record website, on March 11th 1918, a U.S. Army soldier reported cold-like symptoms consisting of sore throat, fever, and headache. By the noon of that same day, over 100 other soldiers reported the same symptoms. This would grow into the first-known outbreak of influenza in the world, infecting 500 million people worldwide, and killing over 20 million people. Robert Krulwich, a scientific correspondent for NPR, explains the process by which a virus enters your body and manifests into something much worse: The influenza virus first enters your respiratory system by inhalation or other, less-common methods. The virus is then expelled into your bloodstream where it latches onto a cell found there.
In two years between 1918 and 1919, A pandemic of influenza swept mercilessly over the planet, killing millions which stood in its path. Miraculously, the exact origin of the pandemic is unclear. What is exceedingly clear, however, is that often the actions of man aided in the spread of the virus, whether due to inadvertent endangerment, close quarters, religious principles, or failure to recognize the true threat that influenza posed.
