Prevention and control of influenza: recommendations of the Advisory Committee on Immunization Practices [ACIP]. MMWR 2007;56[No. RR-6]). The 2008 recommendations include new and updated information. Principal updates and changes include 1) a new recommendation that annual vaccination be adminis­ tered to all children aged 5–18 years, beginning in the 2008–09 influenza season, if feasible, but no later than the 2009–10 influenza season; 2) a recommendation that annual vaccination of all children aged 6 months through 4 years (59 months) continue to be a primary focus of vaccination efforts because these children are at higher risk for influenza complications com­ pared with older children; 3) a new recommendation that either trivalent inactivated influenza vaccine or live, attenuated influenza vaccine (LAIV) be used when vaccinating healthy persons aged 2 through 49 years (the previous recommendation was to administer LAIV to person aged 5–49 years); 4) a recommendation that vaccines containing the 2008–09 trivalent vaccine virus strains A/Brisbane/59/2007 (H1N1)-like, A/Brisbane/10/2007 (H3N2)-like, and B/Florida/4/2006-like antigens be used; and, 5) new information on antiviral resistance among influenza viruses in the United States. Persons for whom vaccination is recommended are listed in boxes 1 and 2. These recommendations also include a summary of safety data for U.S. licensed influenza vaccines. This report and other information are available at CDC’s influenza website (http://www.cdc.gov/flu), including any updates or supplements to these recommendations that might be required during the 2008–09 influenza season.

    COVID-19 Infection Prevention Control Strategies for Massachusetts Masonic Facilities DRAFT 4/6/2020 Introduction With phrases such as “social distancing,” “self-quarantine,” and “flattening the curve” still showing up in the media, flattening the curve” still showing up in the media, blood donations have plummeted as schools, offices and other sites that typically host blood drives shut down to prevent the spread of coronavirus. As Masonic lodges across the commonwealth rise to meet the growing demand for locations, all masons must understand and be able to effectively communicate to others the importance of precautionary measures against the potential spread of CODID-19 while hosting blood drives in our buildings. Background The COVID-19 virus has actually been named "SARS-CoV-2," and the disease it causes has been named "coronavirus disease 2019" (abbreviated "COVID-19"). The virus looks like it's wearing a spiky crown, so it gets the name "corona" from the Latin word for crown. The virus enters cells using the "spike" on its surface to enter and bond with a human cell. Once inside human cells, the virus reproduces. Those reproductions break out of cells and infect other human cells. At a certain point, there are so many virus particles being produced that our normal cells can't work properly and we get sick. Viruses are believed to be transmitted from person-to-person primarily through virus-laden droplets that are generated when infected persons speak, cough, or sneeze. These droplets can be deposited onto the mucosal surfaces of susceptible persons or hard surfaces that are within 6 feet of the droplet sourcei.

  • Anorexia/Cachexia Heart Failure Symptom Management Guideline for Adults, Age 19 and Older in British Columbia
    Anorexia/Cachexia Heart Failure Symptom Management Guideline For adults, age 19 and older in British Columbia What is anorexia? Anorexia is a syndrome characterized by some or all of the following symptoms: loss of appetite, nausea, early satiety, weakness, fatigue, food aversion, and significant physical and/or psychological symptoms. Causes of anorexia are multifactorial and include fatigue, dyspnea, medication side-effects, nausea, depression, anxiety and sodium restricted diets, which may all be found in patients with heart failure. What is cachexia? Cachexia is a syndrome characterized by severe body weight, fat and muscle loss and increased protein catabolism due to underlying disease. The prevalence of cachexia is 16–42% in the heart failure population and is associated with a 50%, 18 month mortality risk independent of variables such as ejection fraction, age and functional ability. How is cachexia diagnosed? Chronic condition with >5% weight loss in <12 months; or body mass index (BMI) <20kg/m2; and 3 out of 5 additional criteria: 1) Fatigue, 2) Decreased muscle strength, 3) Anorexia, 4) Low muscle mass, 5) Abnormal biochemistry *Blood testing to diagnose cachexia in advanced stages of disease is not advocated. Reminder: Malnutrition also affects prognosis in patients with heart failure and is often found in early transitions of the disease. However this symptom management guideline will focus on the assessment and treatment of anorexia and cachexia. Approach to Managing Anorexia/Cachexia Assessment History: When did weight loss begin? How much weight was lost? Obtain baseline (dry) weight. How is [the patients] appetite? What do they eat or drink on a typical day? How has weight loss affected mood? Ask about: nausea, early satiety, dyspnea, poor oral hygiene, dysphagia, malabsorption, bowel habits.

  • Prevention and Control of Influenza During a Pandemic for All Healthcare Settings
    Annex F Prevention and Control of Influenza during a Pandemic for All Healthcare Settings Date of Latest Version: May 2011 1. E-Links have been inserted to direct the reader to the appropriate Section of the Annex. 2. This Annex has been developed for use by healthcare workers including but not limited to those working in infectious diseases, risk management, infection prevention and control, occupational health, occupational hygiene and/or emergency response. 3. The recommendations in this Annex must be interpreted by trained personnel prior to implementation in specific situations, organizations or healthcare settings. 4. A major assumption underlying this Annex was that a pandemic virus would cause severe disease in patients. - Should mild disease occur as in pH1N1, recommendations related to PPE may change. 5. As with all guidance documents related to pandemic influenza, healthcare organizations and personnel should be mindful of specifc provincial/ territorial legislation and policies that may influence or supersede the application of some of the recommendations in this Annex. 6. NOTE: This version of Annex F is being published after the pH1N1 Pandemic (H1N1). The assumptions about influenza epidemiology in this document are generalized to include all potential influenza pandemics and are not specific to pH1N1. To view the PHAC Guidance Documents related to pH1N1 go to: http:///www.phac-aspc.gc.ca/alert-alerte/h1n1/ guidance_lignesdirectrices-eng.php. These Guidance Documents have been adapted from this Annex based on emerging epidemiologic evidence and the impact of pH1N1 infection. 7. In Canada, public health is a shared responsibility of the Federal, Provincial and Territorial governments.

  • Sinusitis, NIAID Fact Sheet
    January 2006 Sinusitis OVERVIEW You’re coughing and sneezing and tired and achy. You think that you might be getting a cold. Later, when the medicines you’ve been taking to relieve the symptoms of the common cold are not working and you’ve now got a terrible headache, you finally drag yourself to the doctor. After listening to your history of symptoms, examining your face and forehead, and perhaps doing a sinus X-ray, the doctor says you have sinusitis. Sinusitis simply means your sinuses are infected or inflamed, but this gives little indication of the misery and pain this condition can cause. Health experts usually divide sinusitis cases into • Acute, which last for 4 weeks or less • Subacute, which lasts 4 to 8 weeks • Chronic, which usually last up to 8 weeks but can continue for months or even years • Recurrent, which are several acute attacks within a year, and may be caused by different organisms Health experts estimate that 37 million Americans are affected by sinusitis every year. Health care providers report nearly 32 million cases of chronic sinusitis to the Centers for Disease Control and Prevention annually. Americans spend $5.8 billion each year on health care costs related to sinusitis. What are sinuses? Sinuses are hollow air spaces in the human body. When people say, “I'm having a sinus attack,” they usually are referring to symptoms in one or more of four pairs of cavities, or sinuses, known as paranasal sinuses . These cavities, located within the skull or bones of the head surrounding the nose, include • Frontal sinuses over the eyes in the brow area • Maxillary sinuses inside each cheekbone • Ethmoid sinuses just behind the bridge of the nose and between the eyes • Sphenoid sinuses behind the ethmoids in the upper region of the nose and behind the eyes Each sinus has an opening into the nose for the free exchange of air and mucus, and each is joined with the nasal passages by a continuous mucous membrane lining.

  • (CATR) Practice 4 “Cold Or Flu?”
    CUNYASSESSMENT TEST IN READING (CATR) Practice 4 “Cold or Flu?” Read the passage below and then answer the multiple choice questions which follow. Check your answers with the answer key. Every winter, at least in cold climates, people begin to become ill, with sneezing, sore throat, and stuffed-up head a few of the most common symptoms. Sometimes other conditions, such as severe cough, are also present, and people wonder whether they have simply caught a cold or are suffering from flu. Since the two illnesses have several common characteristics, the confusion is understandable. Colds are generally rather mild annoyances, but flu can be quite serious and lead to pneumonia. So it is wise to be aware of the differences. Sneezing, stuffy nose, and sore throat are the most common symptoms of colds, and they are often, but not always, present with flu as well. Chest discomfort and coughing may also accompany both ailments, but in flu they have a tendency to become severe, with heavy, hacking coughing that may last for weeks afterward. The symptoms which mark the presence of flu, which are rarely if ever present with the common cold, are headache, high fever, aches and pains all over the body, a general weakness, and exhaustion. Often the illness begins with vague body pains and headache, then quickly escalates as the victim’s temperature becomes elevated and extreme fatigue sets in. Sufferers may find themselves in bed for several days, sleeping much of the time and battling temperatures of 102-104 degrees. Waking moments may be spent coughing uncontrollably.

  • 2019-Weakness-And-Fatigue.Pdf
    Scottish Palliative Care Guidelines – Weakness and Fatigue Weakness and Fatigue Introduction Fatigue is a persistent, subjective feeling of tiredness, weakness or lack of energy related to advanced chronic illness. It has many contributory causes, although the exact aetiology is poorly understood. Patients may use many terms to describe their experience of fatigue. Fatigue is a common symptom in progressive chronic disease. The severity and impact of fatigue may change in the course of the disease trajectory. It is frequently regarded as more distressing than pain by patients. It is often under-recognised by professionals. Fatigue may be unrelated to level of activity and not fully alleviated by rest or sleep. It is multidimensional, affecting physical function, cognitive ability, social, emotional and spiritual wellbeing. Reduced physical function limits participation in preferred activities and activities of daily living. Cognitive involvement limits activities such as reading, driving and social interaction. Fatigue can influence the patient’s decision-making about future treatment and may lead to refusal of potentially beneficial treatment. It is important to recognise that towards the end of life there will be a time point when intervention is no longer appropriate and may be distressing. At this stage, fatigue may provide protection and shielding from suffering for the patient. Assessment • All palliative care patients should be assessed for fatigue and its effects. • Explore the person’s experience and understanding of fatigue. • Acknowledge and validate the reality and significance of the symptoms. • Be aware that patients may have multi-morbidities impacting on fatigue, for example cardiac/respiratory disease, renal or hepatic impairment, malignancy, hypothyroidism, hypogonadism, adrenal insufficiency, neurological conditions.
