Avian Influenza Flu or Bird Flu is a
viral infection that is caused by the bird flu virus also known as the
H5N1 virus.Scientists believe that all flu viruses are
derived from wild birds. The wild birds
carry the viruses inside their intestines. The
virus is contracted through contact with saliva, nasal secretions and feces of
the wild birds.The
virus is also transmitted through contact with contaminated surfaces or
materials.Once
infected, domestic birds either exhibit the “low pathogenic” form which is a
milder form of the flu which sometimes goes undetected causing only mild
symptoms or the “high pathogenic” form which rapidly spreads through flocks
causing death.
The
avian bird flu virus is very contagious among the wild birds but is generally
not lethal. However, once it infects domestic birds like
chickens, ducks and turkeys it is lethal.The Avian influenza virus is an Influenza
Type A (virus similar to the human flu virus) found mainly in birds but this particular subtype (H5N1) of virus has
recently been infecting the human population.
However the risk for human infection is currently low.
The bird flu virus is transmitted through
birds and humans.Let’s go through the symptoms found in birds and humans. These flu viruses occur naturally among birds.
Wild birds worldwide carry the viruses in their intestines, but usually do not
get sick from them.The symptoms for those birds with a mild case
include ruffled feathers and a decrease in egg production. In a severe case, however, birds will
generally die within 48 hours as the virus systematically shuts down various
organs within the bird's body.In order to become infected with bird flu, a
bird must come into contact with the excretions from a contaminated bird. This
can include direct contact as well as contact with materials or other items
that came in contact with the excretions.
Symptoms of avian flu infection in humans
depend on the strain of virus.Once a person is infected by the H5N1 virus it
takes two to eight days before the disease symptoms are observed.The first symptoms the infected individual
feels are the typical flu like symptoms; high temperatures above 38C, diarrhea,
pain in the abdomen, and nose and gum bleeding.The common symptom seen in most of infected
individuals is respiratory distress.This is perceived as difficulty breathing and a crackling sound in the
chest when the infected individual inhales.The kidney and heart also start to fail in
some individuals and lastly leading to death.
Different
types of avian flu virus may cause different symptoms. A person exhibiting bird
flu symptoms must undergo testing in order to confirm that the illness is the
result of a bird flu virus.In general, treatment with the antiviral
medication oseltamivir (Tamiflu) or zanamivir (Relenza) may make the disease
less severe if start taking the medicine within 48 hours after symptoms start. Oseltamivir may also be prescribed for persons
who live in the same house as those diagnosed with avian flu.The virus that causes human avian flu appears
to be resistant to the antiviral medicines amantadine and rimantadine.
Therefore these medications should not be used if an H5N1 outbreak occurs.People with severe infection may need to be
placed on a breathing machine. Experts recommend that persons diagnosed with
avian flu be put in isolation.
The best
way to get rid of bird flu is to prevent the virus. In case
we have to travel to the region where bird flu has spread than we should follow
some medical recommendations.
- Domesticated birds should be avoided
In case
have to be in rural areas then try level
best to avoid coming in contact with the domestic animals and farm houses.
- Open air markets must be avoided
Must
have an urge for visiting and enjoying the local aroma but should avoid such
places as the risk factor of getting infected is very high.
- Wash hands
A consistent habit of washing hands is very
helpful. It helps in keeping infections at an arm’s length. Hand sanitizers
that have at least 60 per cent alcohol are best for using abroad as they do not
ask for water and offer no dangers to children.
- Steer clear of raw eggs
Bird droppings often contaminate eggs should
avoid all those foods that contain raw or uncooked eggs like mayonnaise, ice
cream, and hollandaise sauce.
- Cooking thoroughly
World
Health Organization (WHO) considers that cooked food is not harmful for human beings and offer no risks of bird flu. Should not stop cooking before the
internal temperature of meet reaches 165 F or 74 C.
As for the conclusion, we feel that all of us should be mentally prepared for a global pandemic of the influenza to occur. According to experts of the influenza virus, as a global pandemic of the influenza virus has not occurred in this century, there is a high possibility for one to occur within the next couple of years and a global pandemic is bound to occur – it is just a matter of time for the influenza to develop a new strain.Although human infection of the avian influenza virus is often associated with people who have close contact with poultry, the deadly avian influenza virus is constantly growing and developing over the course of time by antigenic drift and antigenic shift. We have yet to fully understand the influenza virus and its impact in humans. However, for the rest of us, we should be constantly on the look out and on our guards to be regularly updated about the current situation of the influenza virus so that we will not be panicking our lives in times of danger.
