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. • Wear at least the minimum level of respiratory protection, an N95 or higher respirator. • Avoid eating, drinking, smoking and bathroom use while wearing PPE. Additional Guidance • Get the seasonal flu vaccine. • Have your healthcare provider prescribe an adequate supply of antivirals to take during poultry destruction activities and for five days after it ends. • If you develop flu-like symptoms, stay at home except to get medical attention.

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. Influenza pandemics are typically character- Novel Influenza Viruses without ized by the rapid spread of a novel type of Pandemics influenza virus to all areas of the world, resulting In addition to true pandemics, false alarms in an unusually high number of illnesses and emergences of a novel strain with few cases and deaths for approximately 2 to 3 years.

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.

Brick Township COVID-19 Policy
Township of Brick COVID-19 Policy Purpose: To provide clear guidelines to all employees regarding safety precautions and guidelines to guard against contracting the COVID-19 Virus. Background: On average, influenza pandemics occur three times every century, but have no recognizable pattern. (1918-1919 – Spanish Flu, 1957-1958 – Asian Flu, 1968-1969 – Hong Kong Flu), Avian Flu (H5N1 and H9N2). (Currently) COVID-19, 2019-2021 What is COVID-19? Coronavirus disease 2019 (COVID-19) is a respiratory illness that can spread from person to person. The virus that causes COVID-19 is a novel coronavirus that was first identified during an investigation into an outbreak in Wuhan, China. COVID-19 is spreading from person to person in parts of the United States. Risk of infection with COVID-19 is higher for people who are close contacts of someone known to have COVID-19, for example healthcare workers, or household members. Other people at higher risk for infection are those who live in or have recently been in an area with ongoing spread of COVID-19. The first case of COVID-19 in the United States was reported on January 21, 2020. Township of Brick COVID-19 Policy Transmission The virus that causes COVID-19 probably emerged from an animal source, but is now spreading from person to person. The virus is thought to spread mainly between people who are in close contact with one another (within about 6 feet) through respiratory droplets produced when an infected person coughs or sneezes. It also may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes, but the risk is considered to be low.
