YUMMY  ,  ISN’T  IT ?  !!!!
THINGS  LOOK  REALLY GOOD ,  UNTIL  YOU  DO  A  RESEARCH  ON  IT,  SO  LETS  BEGIN  WITH – “  BIRD  FLU  ”
BIRD  FLU
BIRD FLU  :  ( H5N1 avian influenza ), it’s a  virus cause of illness in humans and many other animal species.  This viruses are  constantly mutating and adapting over time to infect and spread among humans. There are only three known subtypes of human flu viruses (H1N1, H1N2, and H3N2)
HISTORY :  First H5N1 known crossover from birds to humans was in 1997 in Hong Kong  - 18 people were infected and 6 died. In January of 2004 an outbreak occurred in poultry farms in  Thailand,  and within weeks it spread to over 10 surrounding countries in Asia (including China, South Korea, Indonesia, Japan).  In February it was isolated in pigs, raising fears of new variant strains.  It was contained by March, after 23 people died and over 40 million chickens were culled.
Human to human transmission has been documented in Vietnam and Thailand, but only familial, or to nurses caring for these patients. When the virus first infected humans the mortality rate was ~65%. Since then it has gone down to ~35%.  This might indicate that the virus is now able to infect more people and spread more quickly through the population, and becoming a global pandemic.
GEOGRAPHICAL  DISTRIBUTION Source :  FAO,WHO , UN The first case of a bird flu virus infecting a person directly, H5N1, was in Hong Kong in 1997. Since then, the bird flu virus has spread to birds in countries in Asia, Africa and Europe
CASES  IN  DIFFERENT PLACES Source :  WHO , UN
CHART  SHOWING  THE  SPREAD  OF  BIRD  FLU
HOW  IT  IS  TRANSMITTED  ? Infected birds transmit through their saliva, nasal secretions, feces and blood. Other Animals  become infected with the virus through direct contact with each  other. H5N1 remains infectious after over 30 days at 0 °C ( 32.0 °F) (over one month at  freezing temperature) or 6 days at 37 °C ( 98.6 °F) (one week at human body  temperature)
SYMPTOMS  OF  BIRD FLU High fever & headache Extreme tiredness & dry cough,  dry cough, runny or stuff nose Sore throat & muscle aches, Nausea ,vomiting, diarrhea, Eye infections,  pneumonia, Respiratory diseases such as acute respiratory  distress and other severe and life-threatening  symptoms are also  associated with avian flu.
Treatment & Vaccines Tami flu  - works by preventing the virus  from  multiplying.  Relenza – another alternative. Currently in 2nd Phase trials Countries working on developing a  vaccine for H5N1 and H9N2
DISASTER  PLANNING : 10 things you can  do to stay healthy.  Stay healthy. Get a seasonal flu shot Wash your hands frequently Use proper respiratory hygiene   Consider wearing a mask Wear gloves Keep your home and work areas clean Be careful about the food you eat
