Why
Ebola is back in the news?
Few years back (1995) my friend and I were skipping the pages of latest
foreign medical journals in our Ispat general library of Rourkela, when my
friend brought my attention to an article “The super highway virus”. The
article discussed mostly on how new virus would invade mankind, kill them
ruthlessly till they compromise with the host and become less virulent. With
best of our efforts we simply cannot eradicate viruses as they too are as old
as this universe. Starting from smallpox until this Ebola outbreak one can
conclude that we should never be complacent about eradication of a particular
virus because something new would appear in its place. There are many factors
which are responsible for spread of the virus. Technology has taken over the
mankind and we feel proud to have conquered the moon, the mars, deep sea and
many more. But viruses are a very intelligent and they modify themselves to
escape from our immune system. The rapid transport system, changing the eating
habits, sex perversions and environment change has lead to these super highway
viral diseases. That’s why Albert Einstein once said “I fear the day that
technology will surpass our human interaction. The world will have a generation
of idiots”
Ebola virus tends to come and go over time. The
viruses are constantly circulating in animals, birds and most likely bats.
Every once in a while, the disease spills over into humans, often when someone
handles or eats undercooked or raw meat from a diseased ape, monkey, or bats.
An outbreak can then happen for several months. And then it becomes quiet
again. Ebola can completely disappear from humans for years at a time. For
example, there were zero recorded cases of Ebola in 2005 or 2006.
Ebola is both rare and very deadly. Since the first
outbreak in 1976, Ebola viruses have infected thousands of people and killed
about one-third of them. Symptoms can come on very quickly and kill fast: Ebola
is more inimical to humans than perhaps any known virus on Earth, except rabies
and HIV-1. And it does its damage much faster than either.
Liberia is one of several countries battling the current outbreak,
which is unprecedented both in the number of cases and in its geographic
scope. It's now hit four countries: Sierra Leone, Guinea, and Liberia have been
joined by Nigeria, which this week saw its first case, after an infected
Liberian man flew to the Nigerian city of Lagos, which is also Africa's largest
city. There are also fears the disease has spread to the country of Togo, where
that man's flight had a stopover. And the virus — which starts off with
flu-like symptoms and often ends with horrific hemorrhaging — had as of July 23
infected 1,201 people in Sierra Leone, Guinea, and Liberia, and killed an
estimated 672 since this winter, according to the World Health Organization.
So what we can do to prevent its spread? Quarantine
the persons coming from African countries and we must tell our travelers not to
venture out of India at this moment without any purpose. Pleasure trips can
wait but Ebola virus would not wait to attack us. The sign and symptoms are
like any viral illness with bleeding tendency and high death rates (80 to 90%)
closely mimicking Dengue hemorrhagic fever. There is no treatment except for
treating the symptoms.
