  • In 1918, a highly virulent form of the influenza virus killed at least 20 million people worldwide. Understanding the origin of the virus that caused this pandemic has been a long-standing goal because of the risk that a similar virus could arise and devastate human populations today.

  • People with flu can spread it to others up to about 6 feet away.
  • Most experts think that flu viruses are spread mainly by droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. Less often, a person might also get flu by touching a surface or object that has flu virus on it and then touching their own mouth or nose.

  • Linens, eating utensils, and dishes belonging to those who are sick should not be shared without washing thoroughly first. Eating utensils can be washed either in a dishwasher or by hand with water and soap and do not need to be cleaned separately. Further, frequently touched surfaces should be cleaned and disinfected at home, work and school, especially if someone is ill.
  • To avoid this, people should stay away from sick people and stay home if sick.
  • Most healthy adults may be able to infect other people beginning 1 day before symptoms develop and up to 5 to 7 days after becoming sick. Children may pass the virus for longer than 7 days. Symptoms start 1 to 4 days after the virus enters the body. That means that you may be able to pass on the flu to someone else before you know you are sick, as well as while you are sick. Some people can be infected with the flu virus but have no symptoms. During this time, those persons may still spread the virus to others.

  • There are three influenza genera - A, B and C;
  • Domestic fowl, ducks, geese, turkeys, guinea fowl, quail and pheasants are susceptible.
  • ...7 more annotations...
  • Disease outbreaks occur most frequently in domestic fowl and turkeys. A particular isolate may produce severe disease in turkeys but not in chickens or any other avian species. Therefore, it would be impossible to generalize on the host range for avian influenza, for it will likely vary with the isolate. This assumption is supported by reports of farm outbreaks where only a single avian species of several species present on the farm became infected. Many species of wild birds particularly water birds and seabirds - are also susceptible, but infections in these birds are generally sub-clinical.
  • athogenic strains could emerge and cause disease in domestic poultry in any country at any time without warning. In fact, outbreaks have occurred at irregular intervals on all continents.
  • he most serious outbreaks in recent times have been reported in Hong Kong 1997-1998 and 2003, Chile 2002, The Netherlands 2003 and South East Asia 2004-2006.
  • he incubation period is 3 to 5 days in general but may be longer. Maximal incubation period is 21 days as defined by the OIE Terrestrial Animal Health Code.
  • Inactivated quality assured oil-emulsion vaccines have been demonstrated to be effective in reducing mortality, preventing disease, or both, in chickens and turkeys. These vaccines, however, may not prevent infection in some individual birds, and if infected could shed virulent virus. Nevertheless, the amount virus shed is considerable less than that of non-vaccinated and infected birds. It is imperative that the circulating antigenic avian influenza virus is known and the vaccine represent this antigenic strain, since there is no cross-protection among the 15 known HA subtypes.
  • Birds that die of peracute disease may show minimal gross lesions, consisting of dehydration and congestion of viscera and muscles.
  • The following diseases must be considered in the differential diagnosis of virulent AI: Other diseases causing sudden high mortality Newcastle disease infectious laryngotracheitis duck plague acute poisonings

  • An estimated 19 million influenza illnesses occur in the United States each year. From 2005-2011, influenza vaccination was estimated to prevent 13.6 million illnesses, 5.8 million medical visits, and nearly 113,000 influenza-related hospitalizations (Kostova et al., 2013). Annually over 200,000 people in the United States are hospitalized because of the flu. People at highest risk for flu-related complications include children younger than 5 years (especially those younger than 2 years old), adults 65 years of age and older, pregnant women, and people who have certain medical conditions such as asthma, heart disease, chronic lung disease, kidney disease, or weakened immune systems due to disease or medication. Each year, thousands of people in the U.S. die because of the flu (Thompson MG et al., 2010). Most of the flu-associated deaths occur in adults 65 years of age and older. More people die from complications from the flu than from any other vaccine-preventable disease.

  • is a viral infection that affects mainly the nose, throat, bronchi and, occasionally, lungs. Infection usually lasts for about a week, and is characterized by sudden onset of high fever, aching muscles, headache and severe malaise, non-productive cough, sore throat and rhinitis. The virus is transmitted easily from person to person via droplets and small particles produced when infected people cough or sneeze. Influenza tends to spread rapidly in seasonal epidemics. Most infected people recover within one to two weeks without requiring medical treatment. However, in the very young, the elderly, and those with other serious medical conditions, infection can lead to severe complications of the underlying condition, pneumonia and death.
