BIRD FLU, A POSSIBLE PANDEMIC
The Bird Flu virus, first
detected in 1997, has gradually become stronger and more diverse
as it has spread across parts of Asia, Europe, and North Africa
with the most recent human case in Egypt (1-July 2007),
Indonesia (1-July 2007), and Viet Nam (2-June 2007).
So far this virus has shown the potential of becoming a
very deadly virus with some further mutation but is not
currently found in North and South America or Australia.
The Bird Flu virus apparently
started in wild Asian waterfowl populations and spread to
chicken populations. From there, it has
spread to cats, pigs, and minks. As far as
humans, the disease is usually associated with individuals that
have been near or handled sick or dead birds or eaten disease
birds without properly cooking. So, the bird
to human transference is occurring but a sustaining
human-to-human transference has not. However,
it is expected to happen any time and one will see World Health
and the US Public Health to immediately ramp up defenses with
tight border screenings and quarantines once such an outbreak
occurs.
The term, pandemic, refers to a
public health emergency where a virus is out of control and
sweeping through a population. There have
been several outbreaks since 1900 such as smallpox and polio;
however with influenza there have been three: Spanish Flu
(1918-1919), Asian Flu (1957-1958) and Hong Kong Flu
(1968-1969). Both the Hong Kong and Asian Flu
targeted infants, elderly, pregnant, and the sick. However,
the Bird Flu parallels the Spanish Flu, which targeted healthy
15-35 year-old and created a significantly greater number of
deaths than the other two.
Influenza (flu) is a disease that attacks the respiratory
tract in humans. It arrives suddenly and may
include, fever, headache, tiredness, dry cough, sore throat,
nasal congestion, and body aches, and may result in
complications such as pneumonia. The virus is
generally heavier than air because it is attached to moisture
droplets, so they will eventually settle on flat surfaces such
as counter tops, desks, tables, banisters, etc. Other
points of contact include phone handles, computer keyboards,
grocery carts handles, restaurant tabletops, door push plates,
and doorknobs.
Note that the above symptoms, other than high number of
people experiencing complication, is true also for the more
common seasonal winter influenzas and may be fought or prevented
in the same manner that are listed here.
The virus enters the body
through the mouth, nose, eyes, or any open cut or sore.
If one needs to be around someone that has contracted the
virus of this nature, your protection will a face mask (N95 or
N100) and goggles such as safety glasses with side shields.
This seems a bit extreme for most situations but in the
case of a deadly virus such as the bird flu in your home, it is
quite necessary.
The hands often become involved in transporting the virus
and are then used to rub an eye or scratch a nose and, thus
infected you. Hands should be kept
clean by wearing gloves, using a strong sanitizer, or frequently
washing. The washing should take at least 20
seconds to scrub with soap and running water. Washing should
include through rinsing of the soap, as the soap will contain
trapped pathogens.
The virus is initially
transmitted by direct or indirect contact with infected areas or
persons and by airborne droplets (sneezing and coughing).
These airborne droplets may remain in the air for as long
as 30 minutes and long since the person who has coughed or
sneezed as left the area. For this reason,
our society has to actively encourage blocking of sneezing and
coughs which will greatly impact the transference of the
seasonal flu and the more deadly varieties, such as Bird Flu.
Yes, there is a risk of a
pandemic but implementing the above procedures will go a long
way to preventing the flu from reaching that out-of-control
level.
