  • Influenza Virus Infections in Humans October 2018
    Influenza virus infections in humans October 2018 This note is provided in order to clarify the differences among seasonal influenza, pandemic influenza, and zoonotic or variant influenza. Seasonal influenza Seasonal influenza viruses circulate and cause disease in humans every year. In temperate climates, disease tends to occur seasonally in the winter months, spreading from person-to- person through sneezing, coughing, or touching contaminated surfaces. Seasonal influenza viruses can cause mild to severe illness and even death, particularly in some high-risk individuals. Persons at increased risk for severe disease include pregnant women, the very young and very old, immune-compromised people, and people with chronic underlying medical conditions. Seasonal influenza viruses evolve continuously, which means that people can get infected multiple times throughout their lives. Therefore the components of seasonal influenza vaccines are reviewed frequently (currently biannually) and updated periodically to ensure continued effectiveness of the vaccines. There are three large groupings or types of seasonal influenza viruses, labeled A, B, and C. Type A influenza viruses are further divided into subtypes according to the specific variety and combinations of two proteins that occur on the surface of the virus, the hemagglutinin or “H” protein and the neuraminidase or “N” protein. Currently, influenza A(H1N1) and A(H3N2) are the circulating seasonal influenza A virus subtypes. This seasonal A(H1N1) virus is the same virus that caused the 2009 influenza pandemic, as it is now circulating seasonally. In addition, there are two type B viruses that are also circulating as seasonal influenza viruses, which are named after the areas where they were first identified, Victoria lineage and Yamagata lineage.

  • Influenza Booklet
    Explaining Courtesy of Your Pinal County Board of Supervisors FOREWORD As members of the Pinal County Board of Supervisors, we ask each citizen to review this booklet as a first step towards pandemic influenza preparedness. This booklet contains the information needed to understand how to help prevent this disease and how to create a preparedness plan for your home and business. Recently it has been difficult to read a newspaper or watch a newscast without some mention of the avian influenza (flu) or influenza (flu) pandemic. Throughout history, flu pandemics have proven to have devastating effects on the health of our communities and economy. In 1918, the world was devastated by the Spanish Flu Pandemic. The Spanish flu killed around 675,000 Americans and tens of millions worldwide. Today, we are the first generation in history to anticipate a flu pandemic. Your federal, state, and local governments have been working for the past two years on plans to minimize the potentially devastating effects of a flu pandemic. Scientific experts throughout the world agree that it is simply a matter of time before the world sees its next flu pandemic. The avian flu is a potential, and some say likely, source of the next flu pandemic and as such its effects and transmission throughout flocks of poultry and wild birds is being closely monitored worldwide. The concern that health officials have regarding avian flu is that the effects closely mimic that of the devastating Spanish Flu Pandemic of 1918. At this point avian flu is only easily transmissible between birds. However, a mutation could take place at any time that would allow transmission between humans to occur as easily as it does each year for seasonal flu.

  • The Next Influenza Pandemic: Lessons from Hong Kong, 1997
    Perspectives The Next Influenza Pandemic: Lessons from Hong Kong, 1997 René Snacken,* Alan P. Kendal, Lars R. Haaheim, and John M. Wood§ *Scientific Institute of Public Health Louis Pasteur, Brussels, Belgium; The Rollins School of Public Health, Emory University, Atlanta, Georgia, USA; University of Bergen, Bergen, Norway; §National Institute for Biological Standards and Control, Potters Bar, United Kingdom The 1997 Hong Kong outbreak of an avian influenzalike virus, with 18 proven human cases, many severe or fatal, highlighted the challenges of novel influenza viruses. Lessons from this episode can improve international and national planning for influenza pandemics in seven areas: expanded international commitment to first responses to pandemic threats; surveillance for influenza in key densely populated areas with large live-animal markets; new, economical diagnostic tests not based on eggs; contingency procedures for diagnostic work with highly pathogenic viruses where biocontainment laboratories do not exist; ability of health facilities in developing nations to communicate electronically, nationally and internationally; licenses for new vaccine production methods; and improved equity in supply of pharmaceutical products, as well as availability of basic health services, during a global influenza crisis. The Hong Kong epidemic also underscores the need for national committees and country-specific pandemic plans.

  • Bronchiolitis
    Bronchiolitis What is bronchiolitis? Bronchiolitis is a viral infection of the lungs that usually affects infants. There is swelling in the smaller airways or bronchioles of the lung, which causes coughing and wheezing. Bronchiolitis is the most common reason for children under 1 year old to be admitted to the hospital. What are the symptoms of bronchiolitis? The following are the most common symptoms of bronchiolitis. However, each child may experience symptoms differently. Symptoms may include: Runny nose or nasal congestion Fever Cough Changes in breathing patterns (wheezing and breathing faster or harder are common) Decreased appetite Fussiness Vomiting What causes bronchiolitis? Bronchiolitis is a common illness caused by different viruses. The most common virus causing this infection is Respiratory Syncytial Virus (RSV). However, many other viruses can cause bronchiolitis including: Influenza, Parainfluenza, Rhinovirus, Adenovirus, and Human metapneumovirus. Initially, the virus causes an infection in the upper airways, and then spreads downward into the lower airways of the lungs. The virus causes swelling of the airways. Mucus is also produced in the airways. This narrowing of the airways can make it difficult for your child to breath, eat, or nurse. How is bronchiolitis diagnosed? Bronchiolitis is usually diagnosed on the history and physical examination of the child. Antibiotics are not helpful in treating viruses and are not needed to treat bronchiolitis. Because there is no cure for the disease, the goal of treatment is to make your child comfortable and to support their symptoms. This treatment may include suctioning to keep the airways clear, extra oxygen if the blood oxygen levels are low, or hydration if your child is not able to feed well.

  • Avian Influenza Outbreaks in the United States Q&A
    USDA Questions and Answers: Avian Influenza Outbreaks in the United States April 2015 Avian Influenza in the United States Q. Does highly pathogenic avian influenza currently exist in the United States? A. Since mid-December 2014, there have been several ongoing highly pathogenic avian influenza (HPAI) H5 incidents along the Pacific, Central and Mississippi Flyways. Cases in wild birds, captive wild birds, backyard poultry or commercial poultry have been reported in Arkansas, California, Iowa, Idaho, Kansas, Minnesota, Missouri, Montana, North Dakota, Nevada, Oregon, Utah, South Dakota, Washington, Wisconsin and Wyoming. Details are available on the APHIS website. The HPAI strains detected recently in these flyways are H5N2, H5N8 and H5N1, but primarily H5N2 in turkey flocks. Q. Can people catch these highly pathogenic avian influenza strains that are being detected in these outbreaks? A. CDC considers the risk to people from these HPAI H5 viruses in wild birds, backyard flocks, and commercial poultry, to be low. No human infections with these viruses have been detected at this time, however, similar viruses have infected people. It’s possible that human infections with these viruses may occur. While human infections are possible, infection with avian influenza viruses in general are rare and – when they occur – these viruses have not spread easily to other people. These reports of H5-infected wild birds and poultry in the United States do not signal the start of a pandemic. Q. How is USDA dealing with these HPAI outbreaks? A. The United States has the strongest AI surveillance program in the world so that the food supply remains safe.

  • Avian Influenza Viruses in Hong Kong: Zoonotic Considerations
    2 Avian influenza viruses in Hong Kong: zoonotic considerations K.F. Shortridge Abstract Since the mid-1970s, Hong Kong has functioned as an influenza sentinel post for southern China, a region identified as a hypothetical epicentre for the emergence of pandemic influenza viruses. Nineteen ninety-seven marked the coming-of-age of animal-influenza studies with the recognition in Hong Kong of an incipient pandemic situation brought about by the infection of chicken and humans with an avian influenza H5N1 (H5N1/97) virus. Slaughter of all poultry across the Hong Kong SAR possibly averted a pandemic. Tracking down the source of the H5N1/97 virus to geese and quail and precursor avian H5N1, H9N2 and H6N1 viruses revealed that it was a triple reassortant. This provided a framework for influenza-pandemic preparedness at the baseline avian level, H5N1-like viruses being recognized in chicken in 2001 and twice in 2002; at the human level, H9N2 and H5N1-like isolations were made in 1999 and 2003, respectively. In contrast to Europe and elsewhere, where outbreaks of disease in chicken (by H5 and H7 subtypes) often follow migratory bird activity in an area and the subsequent detection of low-pathogenic avian influenza (LPAI) and highly pathogenic avian influenza (HPAI) virus forms, in southern China, chicken and other poultry are raised in a permanent, year-round avian-influenza milieu as a consequence of duck-raising practices. Given this long-established milieu, the question is raised whether East- Asian avian influenza viruses comprise a group with a greater propensity for interspecies transmission and potential for pandemicity.

  • Avian Flu | Poultry Workers
    QUICK CARDTM Avian Flu Poultry Workers Avian flu is a viral disease and it can be very contagious and even deadly in poultry (e.g., chickens, turkeys, ducks). Of great concern are the highly pathogenic avian influenza (HPAI) viruses (e.g., H5N1, H7N9) that have killed millions of birds and have infected humans in other countries. If avian flu viruses are detected in the U.S., take appropriate precautions. Signs of Avian Flu Illness in Birds Sudden death; lack of energy, appetite, and coordination; purple discoloration and/or swelling of various body parts; diarrhea; nasal discharge; coughing; sneezing; and reduced egg production and/or soft-shelled or misshapen eggs. Avian Flu Symptoms in Humans Range from fever, cough, sore throat and muscle aches to nausea, abdominal pain, vomiting, diarrhea, eye infections, difficulty breathing, pneumonia and severe respiratory disease. Symptoms may depend on which virus caused the infection but are often similar to those of human seasonal influenza. When Engaged in Depopulation Activities • Wash hands thoroughly (for at least 15 seconds) and frequently, preferably with soap and water (or an alcohol- based hand rub, if soap and water are not available). • Wear lightweight, disposable gloves or heavy-duty rubber work gloves that can be disinfected. Avoid touching your face with gloved hands. Wash hands after removing gloves and other personal protective equipment (PPE). • Wear disposable outer garments, coveralls or surgical gowns with long, cuffed sleeves and with a sealed apron. • Wear disposable shoe covers or boots that can be cleaned and disinfected. • Wear safety goggles and disposable head or hair cover.

  • The Effect of Corticosteroids on Mortality of Patients with Influenza
    Ni et al. Critical Care (2019) 23:99 https://doi.org/10.1186/s13054-019-2395-8 RESEARCH Open Access The effect of corticosteroids on mortality of patients with influenza pneumonia: a systematic review and meta-analysis Yue-Nan Ni1, Guo Chen2, Jiankui Sun3, Bin-Miao Liang1* and Zong-An Liang1 Abstract Background: The effect of corticosteroids on clinical outcomes in patients with influenza pneumonia remains controversial. We aimed to further evaluate the influence of corticosteroids on mortality in adult patients with influenza pneumonia by comparing corticosteroid-treated and placebo-treated patients. Methods: The PubMed, Embase, Medline, Cochrane Central Register of Controlled Trials (CENTRAL), and Information Sciences Institute (ISI) Web of Science databases were searched for all controlled studies that compared the effects of corticosteroids and placebo in adult patients with influenza pneumonia. The primary outcome was mortality, and the secondary outcomes were mechanical ventilation (MV) days, length of stay in the intensive care unit (ICU LOS), and the rate of secondary infection. Results: Ten trials involving 6548 patients were pooled in our final analysis. Significant heterogeneity was found in all outcome measures except for ICU LOS (I2 =38%,P = 0.21). Compared with placebo, corticosteroids were associated with higher mortality (risk ratio [RR] 1.75, 95% confidence interval [CI] 1.30 ~ 2.36, Z =3.71,P = 0.0002), longer ICU LOS (mean difference [MD] 2.14, 95% CI 1.17 ~ 3.10, Z =4.35,P < 0.0001), and a higher rate of secondary infection (RR 1.98, 95% CI 1.04 ~ 3.78, Z = 2.08, P = 0.04) but not MV days (MD 0.81, 95% CI − 1.23 ~ 2.84, Z =0.78,P = 0.44) in patients with influenza pneumonia.
