HOST

• Highly pathogenic avian influenza isolates have
  been obtained primarily from chickens and
  turkeys 
• It is reasonable to assume all avian species are
  susceptible to infection

5
TRANSMISSION

• Direct contact with secretions from infected
  birds, excretion especially feces 
• Contaminated feed, water, equipment and clothing 
  
• Clinically normal waterfowl and sea birds may
  introduce the virus into flocks 
• Broken contaminated eggs may infect chicks in
  the incubator

SOURCES OF VIRUS

• Feces, respiratory secretions 
• Highly pathogenic viruses may remain viable for
  long period of time in infected feces, tissues
  and water

WHO Bird droppings prime origin of bird flu(
2004-01-17 1020) (chinadaily.com.cn/Agencies)

• Bird flu, which has killed at least 13 people in
  Vietnam, is largely transmitted through bird
  droppings and uncooked meat, the World Health
  Organization (WHO) said, doubting the need to ban
  imports of chicken meat by some countries.

Symptoms of bird flu in humans

• High fever (101-104 degrees Fahrenheit)
• Diarrhea
• Cough-when mucus is produced it may be
• bloody
• Shortness of breath
• Low white blood cell counts
• Chest "crackles" heard with
• a stethoscope

Identifying Infectious Bird Diseases In Birds A
list of symptoms

• Sudden increase in bird deaths in your flock
• Sneezing, gasping for air, coughing and nasal
  discharge
• Watery and green diarrhea
• Lack of energy and poor appetite
• Drop in egg production or soft- or thin-shelled
  mis-shapen eggs
• Swelling around the eyes, neck and head

11
COMPLICATIONS
Most people with bird flu have signs and symptoms
of conventional influenza. Some also develop
life-threatening complications such as viral
pneumonia and acute respiratory distress syndrome
But the greatest complication of bird flu is
still hypothetical
12
SOLUTIONS

• No specific treatment
• But now, the primary treatment option remains the
  flu drug oseltamivir (Tamiflu), that works by
  preventing the virus from escaping its host cell

13
Sanitary prophylaxis

• Avoidance of contact between poultry and wild
  birds, particularly waterfowl 
• Avoidance of the introduction of birds of unkown
  health status into a flock 
• Control of human traffic 
• Proper cleaning and disinfection procedures 
• Practice an all in-all out system in the
  poultry farm

14
In outbreaks

• Slaughtering of all birds 
• Disposal of carcasses and all poultry products 

• Cleaning and
• disinfection 
• Allow at least 21
• days before
• restocking

15
Prevention

• Culling.
• Surveillance programs.
• Banned birds.
