Finally, the giant of Africa,Nigeria has been removed from
the list of polio endemic countries.
According to world health organization,it usually takes
three years without cases before a country can be declared as polio free and
Nigeria has gone more than a year without a case of a wild naturally occurring
polio.this is an important milestone for
Nigeria.this also means that there are
two endemic countries which include Pakistan and Afghanistan where transmission of the paralyzing virus has never
been interrupted.
Let me enlighten you more about this virus called polio
polio starts with it being a disease that is
caused by a virus. This virus can be spread from person to person. It usually
enters through the mouth and then spreads in the intestine. Excrement then
transfer the disease. This is a problem in areas with poor hygiene practices.
When it reaches another person it will then invade the brain and spinal cord
which can result in paralysis. If left untreated, it can be deadly. This
disease only affects humans.
The first polio recorded case of
polio was in 1773. Sir Walter Scott was said to be struck with a teething fever
which took the use of his right leg. The first epidemics began to appear in
Europe and the United States around the 1900's. In 1841 there was an outbreak
in Louisiana and the next one did not take place until 1893 in Boston. In
Vermont the following year there were 18 deaths and a total of 132 people
affected by the disease. By the year 1907 there were about 2,500 cases reported
and that number continued to grow over the course of the next 30 years.
Almost all people, around 95
percent, affected with polio have no symptoms. The rest of the infected
population will have mild symptoms. Some symptoms can include things like
fever, tiredness, nausea, headache, and stiffness in the neck and back, pain in
the limbs, and other flu-like symptoms. The eventual result, which happens in
about one percent of cases, is permanent paralysis. Around five to ten percent
of those paralyzed will die after the polio strikes the respiratory muscles.
As of 2013, the most effect way to
treat polio is by preventing it. The first attempt at a polio vaccine was in
1935. It resulted in allergic reaction to the medicine and no immunities to the
disease. In the late 1940's and early 1950's a research group from Boston
Children's Hospital tried again. They were able to cultivate the virus in human
tissue. Because of this, they ultimately developed the polio vaccine. They were
recognized with a Noble Peace Prize in 1954. By 1957 the mass population in the
United States had been vaccinated. As a result, the last know outbreak was in
1979 in several Amish communities in the Midwest.
In the late 1940s and early 1950's,
polio invaded over 35,000 people each year in the United States. By 1979,
because of vaccinations, the country became polio free. However, the disease
continues to affect others across the globe. In 1988 there were am estimated
350,000 cases of polio across the world. In 2012 the number dropped to around
220. There are still three countries that have never been rid of the polio
virus. The people of Afghanistan, Nigeria, and Pakistan still have fears of
being infected.
Over the years polio effected people
in large numbers. Over time, pediatricians and other physicians discovered the
best way to prevent the spread of this virus is with vaccinations. Most
children are vaccinated within the first year of their lives. With no reported
cases in the country since the 1970's, this vaccine may eventually become
obsolete.
