Poliovirus

Documented in a stone carving from ancient times of the Kingdom Period of Egypt around 1300 BC, a man is depicted with a dangling foot and withered right leg who was very likely to have been suffering from the effects of poliomyelitis. Poliomyelitis, an infectious viral disease that was easily contracted in unsanitary conditions, has been around since ancient times. The ruthless virus attacked the nervous system by specifically targeting gray matter, tissue in the spinal cord and brain…

Doctor Robert W. Sears, author of The Vaccination Book: Making the Right Decisions for Your Child, once said, “With the growing mistrust of vaccinations... more and more parents are saying no to vaccines. Illnesses that are very rare right now, that most parents don’t have to fear...” Vaccines have been used for decades, and have continued to change and advance as the scientific field has gained more knowledge on defeating a multitude of diseases and sicknesses. The question is how are vaccines…

all over the world were feared that they would end up getting the disease, as well. Although polio can cause paralysis and death, the majority of people who are infected with the poliovirus don’t become sick and are never aware they’ve been infected with polio. Some people who develop symptoms from the poliovirus contract nonparalytic polio, which is a type of polio when you don’t become paralyzed. Some symptoms are fever, headache, sore throat, and muscle tenderness or weakness.…

disease trying to develop an effective vaccine. The first successful vaccine was developed by Jonas Salk, first tested in 1952, and announced to the world by Salk on April 12, 1955. The Salk vaccine, or inactivated poliovirus vaccine (IPV), consists of an injected dose of killed poliovirus and the body will produce antibodies against polio. Right after many vaccines were produced and distributed to the public. With everyone vaccinated it…

The United States has been suffering from outbreaks of diseases since the beginning of colonial America, but more importantly, during 1914 to present day 2014. Franklin D. Roosevelt, a former president who was affected by the polio virus in 1921, stated, “If civilization is to survive, we must cultivate the science of human relationships - the ability of all peoples, of all kinds, to live together, in the same world at peace” (Franklin). Civilization must work together in difficult times to…

Medical Research Laboratories at the University of Toronto. By the year 1951, poliovirus was being developed in test tubes, however there wasn’t enough being produced to be sustainable for a vaccine prior to Dr. Arthur E. Franklin’s suggestion of “Medium 199.” Dr. Joseph F. Morgan, the original creator of the nutrient base, was a close friend of Franklin’s, and after addressing the problems with the growth of the poliovirus, game some "199" to Franklin during 1951 (The Story of Polio), which…

Etiology: Poliomyelitis aka Polio, is a crippling and potentially death causing disease caused by the Poliovirus. Polio contains RNA and has three types of serotypes. The virus can spread in so many ways. By contact by infected feces, contact with phlegm/mucus from the nose or mouth, or by person to person contact. It starts with entering through the mouth and nose, replicates and spreads in throat and gastrointestinal tract. Then potentially gets absorbed and disbursed out into the blood and to…

period, causing most host-to-host transmission. The poliovirus enters the nervous system by crossing the blood-brain barrier or by axonal transportation from a peripheral nerve. It then causes nervous system infection resulting to asymmetric weakness and muscle atrophy because of the loss of motor neurons and denervation of the skeletal muscles. Even though polio can cause paralysis and death majority of the people who are infected with the poliovirus don't get sick and are never aware they…

You see,polio or poliomyelitis is a serious disease that affects the nerves of the spine and often makes a person permanently crippled,the virus originated from the poliovirus in 1894,the first outbreak of polio in epidemic formed in the U.S. occurred in vermont with 132 cases.But the first actually polio infected human was discovered in Europe in the 20th century.Also polio is contracted by poor sanitation areas and the virus easily spreads through the fecal-oral route also by contaminated…

Vaccine Polio Vaccine was found in 1953 by a doctor named Jonas Salk to cure the virus “Poliomyelitis”. Polio attacks the nerve cells and sometimes the central nervous system, causing muscle wasting, paralysis, and even death. Polio is caused by the poliovirus, a highly contagious virus specific to humans. The virus usually enters the environment in the feces of someone who is infected. From this outbreak, many people including children have suffered severe injuries. A 1916 polio epidemic in…
