FactSheet Avian Flu Avian influenza (AI) viruses infect wild birds and poultry (e.g., chickens). They are divided into two groups based upon the severity of the disease they produce in poultry: low pathogenicity AI (LPAI) viruses and highly pathogenic AI (HPAI) viruses. LPAI viruses occur naturally in wild birds but can spread to poultry where they generally cause minor illness. However, HPAI viruses are highly contagious and cause high mortality in poultry. While LPAI viruses pose little threat to human health, certain HPAI viruses have caused serious illness and even death. Of particular concern to public health are the HPAI H5N1 viruses that are spreading rapidly in some parts of the world. HPAI H5N1 viruses have caused the deaths of millions of birds and of over 140 people worldwide. These deaths have thus far been restricted to Asia, the Middle East, and Africa. As of October 2006, the HPAI H5N1 virus has not been found in the United States. Although HPAI H5N1 viruses have the potential to develop into pandemic viruses if they acquire the ability to pass readily from human-to-human, thus far, there has been only very limited transmission between humans. This document provides interim guidance for protecting employees who may be exposed if there is an outbreak of HPAI H5N1 in the United States. For the most up-to-date information on the occurrence of HPAI H5N1 outbreaks throughout the world, as well as other HPAI virus outbreaks that may also pose a hazard to human health, consult the Department of Health and Human Services (HHS) web site at: www.avianflu.gov. Symptoms of Avian Influenza (AI) in Humans Range from: fever, cough, sore throat and muscle aches; to diarrhea, eye infections, pneumonia and severe respiratory diseases; and other severe and life-threatening complications. The symptoms of avian influenza may depend on which virus caused the infection but often are similar to those associated with human seasonal influenza. Individuals with these symptoms may be experiencing an illness other than influenza. Therefore, laboratory tests can be used to confirm avian influenza infection in humans. How People Become Infected So far, most cases of avian influenza infection in humans have resulted from direct contact with infected poultry (e.g., domesticated chickens, ducks, and turkeys) or contact with surfaces soiled with discharges from their mouths, beaks, or with feces. Other possible means of infection include consuming raw or undercooked poultry or poultry products and inhaling contaminated poultry particles (e.g., this could occur during butchering). Eating properly handled and cooked poultry and eggs is safe. Cooking poultry to an internal temo perature of 165 F and eggs until they are firm throughout kills the AI virus. Employees at Potential Risk of Exposure • Poultry employees involved in eradication activities (for example, depopulating poultry); • Animal handlers (other than poultry employees); • Laboratory employees; • Health care workers treating patients with known or suspected avian influenza viruses; • Food handlers; • Airport personnel with close exposure to passengers suspected of being avian influenzainfected; and • Travelers on temporary work assignments abroad in areas affected by HPAI H5N1 outbreaks. Treatment Prescription antiviral drugs approved for influenza (based on seasonal outbreak data) may be of some benefit in treating avian flu infection in humans. However, influenza viruses can become resistant to these drugs, so these medications may not always work. For some of these drugs to be most effective, they must be taken within 48 hours after the first sign of symptoms. Additional drugs may be developed for influenza, and it is not yet known whether they will be more effective. General Precautions for People Who May Be Exposed to Avian Flu Viruses • Use proper hand hygiene practices. Clean your hands often and thoroughly, preferably using soap and water for 15-20 seconds (or a waterless, alcohol-based hand rub when soap is not available), especially if you are handling poultry or poultry products. • If possible, avoid contact with poultry and other birds suspected or known to be infected. • Avoid eating uncooked or undercooked poultry or poultry products. • If you are sick, stay at home except to get medical attention. • Cover your mouth and nose when you cough or sneeze. Specific control measures should be selected as appropriate to the particular exposure situation. • If eradication (depopulating) of poultry is necessary, use the following personal protective equipment (PPE): ◆ Disposable gloves or gloves that can be disinfected; ◆ Protective clothing (e.g., long-sleeved coveralls with waterproof aprons that can be disinfected or disposed of); ◆ ◆ ◆ ◆ Disposable protective shoe covers or boots that can be cleaned and disinfected; Safety goggles; Wear at least the minimum level of respiratory protection, N95 or higher respirator; and Employees should follow proper containment and decontamination procedures when wearing PPE. • Employees should check with their health care providers about seasonal flu vaccine or antiviral drugs. • If you believe that you may have been exposed to avian influenza: ◆ Monitor your health for 10 days; ◆ If you become ill with fever and develop a cough or difficulty breathing, consult a health care provider about what steps to take; and ◆ Do not travel while sick, and limit contact with others as much as possible to help prevent the spread of any infectious disease. Training Employees with potential for exposure should receive training on hazards associated with exposure to HPAI H5N1 and on the procedures in place in their facility to isolate and report cases and reduce exposures.

Of great concern are the highly pathogenic avian influenza (HPAI) H5N1 viruses that have killed millions of birds and infected humans in other countries. If these viruses are detected in the U.S. or if you travel on work assignments or are employed in countries that have HPAI H5N1 outbreaks, take appropriate precautions. Avian Flu Symptoms in Humans Range from fever, cough, sore throat and muscle aches; to diarrhea, eye infections, pneumonia and severe respiratory diseases. The symptoms of avian influenza may depend on which virus caused the infection but are often similar to those associated with human seasonal influenza. How Humans Are Infected • Contact with sick poultry or surfaces soiled with discharges from their mouths or beaks, or with feces. • Inhaling contaminated particles from poultry. Treatment Some prescription antiviral drugs may be effective. General Precautions • Wash hands thoroughly and frequently, for 15-20 seconds, preferably with soap and water. • Avoid contact with possibly infected poultry. • Avoid consuming uncooked or undercooked poultry or poultry products. Precautions When Exposed • Use appropriate personal protective equipment (PPE): ◆ Disposable gloves or gloves that can be disinfected; ◆ Protective clothing (long-sleeved coveralls with a waterproof apron); ◆ Disposable shoe covers or those that can be disinfected; ◆ Safety goggles; and ◆ Wear at least the minimum level of respiratory protection, N95 or higher respirator. • Employees should remove all PPE at work to avoid taking contaminated items home. Additional Guidance • Get the seasonal flu vaccine. • If you develop flu-like symptoms, stay at home except to get medical attention.

De gran preocupación son los virus altamente patogénicos de gripe aviar, (HPAI) H5N1, los cuales han causado la muerte a millones de aves y han infectado a humanos en otros países. Si estos virus se encontraran en los Estados Unidos, o si usted viaja por razones de trabajo o ha sido contratado en países que tienen brotes de HPAI H5N1, tome las precauciones apropiadas. Los Síntomas de la Gripe Aviar en Humanos Varían desde: fiebre, tos, dolor de garganta y dolores musculares; a diarrea, infecciones oculares, neumonía, y enfermedades respiratorias serias; y otras complicaciones severas. Los síntomas de la gripe aviar pueden variar según el virus que haya causado la infección, pero son con frecuencia similares a los que están asociados con la gripe de temporada en humanos. Como se Infectan los Seres Humanos • Con el contacto de aves de corral enfermas o con superficies manchadas con descargos de su boca (aves de corral), nariz o con excrementos. • Inhalando partículas contaminadas de aves de corral. Tratamiento Algunas medicinas antivirales, pueden ser efectivas. Precauciones Generales • Lávese las manos completamente y con frecuencia, por 15 o 20 segundos, preferiblemente con jabón y agua. • Evite el contacto con aves de corral, que hayan sido posiblemente infectadas. • Evite consumir aves de corral o productos de aves de corral sin cocinar, o que no estén bien cocidos. Precauciones Cuando Este Expuesto • Use un equipo de protección personal apropiado (PPE por sus siglas en Inglés): ◆ Guantes desechables o guantes que puedan desinfectarse ◆ Ropa que lo proteja (ropa entera, de manga larga que le cubra todo, con un delantal impermeabilizado); ◆ Cubiertas desechables para zapatos o que se puedan desinfectar; ◆ Lentes de Seguridad; y ◆ Use por lo menos el nivel mínimo de protección respiratoria, respirador N95 o mayor. • Los empleados deben de quitarse todo el equipo personal de protección (PPE por sus siglas en Inglés), en su trabajo para evitar que se lleven a casa, objetos contaminados.
