Poliovirus

Polio is an infectious disease. This condition is caused by a virus, most often the poliovirus. This condition spreads easily from person-to-person (contagious). The virus can spread by: • Eating food or drinking water contaminated with the virus found in human waste. • Contact with infected mucus or sputum from the nose or mouth. • Contact with infected air droplets from a cough or sneeze. There are three types of polio: • Abortive polio. • Nonparalytic polio. • Paralytic

WHAT IS POLIO? Poliomyelitis or polio, is highly contagious viral infection that can lead to abnormal conditions such as paralysis, breathing problems, or even lead to death. The poliomyelitis is from the word “grey”, myelos referencing to the “matter” of the spinal cord, -itis meaning inflammation. So it means the inflammation of the grey matter of the spinal cord. Poliomyelitis can be categorize as either asymptomatic or symptomatic. About

Pathogenesis In 99% of poliovirus infections, alpha and beta interferons limit replication of the poliovirus in nonneural tissues, which causes the infection to end (Racaniello, 2005). There are 1-2% of poliovirus infections where the interferons do not work as well, and the virus spreads to extraneural sites and then to the central nervous system causing poliomyelitis (Racaniello, 2005). Infection with poliovirus causes the inhibition of host cap-dependent translation, DNA- dependent RNA synthesis

acid-resistant, stable, highly tissue specific and consists of a single-stranded, positive RNA. Polio virus is able to reside in the throat or intestinal tract of humans. Poliomyelitis is a highly contagious infectious disease which has three strains, poliovirus 1 (PV1), PV2 and PV3. Polio virus, although rare in developed countries, can be found in many under-developed countries due to the uncommonness of vaccinations there. Polio is known as a disease of development. The oldest known record of polio is

 Poliovirus is an enterovirus which infects the guts then spreads through blood to infect the central nervous system causing paralysis though infection is over 90% asymptomatic.  The challenges eradicating polio range from socio-cultural factors to political and economical factors. There are mainly three endemic areas remaining namely: Nigeria, Pakistan and Afghanistan.  The solution to the challenges would vary from countries and communities with specific issues. But the direct involvement of

Animal Testing is Essential On the other had, some individuals deem animal testing necessary for the furthering of the medical field. There have been illnesses and diseases that have been eradicated due to animal experimenting. One such disease a vaccine that was resulted by successful experimentation on animals to combat it is the poliomyelitis vaccine Continuing, one essential aspect to consider when evaluating the similarities between humans and animals is the amount shared genes. According to

Anterior Poliomyelitis is a highly infectious disease that attacks the anterior horn of the spinal cord. Poliomyelitis translates to grey spinal matter inflammation. Polio is caused by a picorna virus that enters the body through mucus membranes and then multiplies in the throat and being an acidophile, can survive well in the stomach and small intestine. When viremia occurs and persists, the virus will penetrate the capillary wall. Once this happens, it enters the central nervous system and begins

Hi Antoinette, great post with a lot of detailed information. During my research of the poliovirus and vaccine, I was in complete shock. As we know the food and drug administration (FDA) regulates and approves our vaccines for public use. In 1955 the FDA approved and provided licensure for the polio vaccine for public use within two hours (Gale, & Null, 2015). This was the fastest vaccine approved by the FDA ever. Although this resulted in a nightmare and many children and adults were affected with

Polio or poliomyelitis is an infectious disease that is caused by the poliovirus. The poliovirus is a virus that only infects humans and it lives in a person’s throat, intestines and feces. The etiological factors that are associated with polio are feces containing the virus, food and water contaminated by fecal matter with the disease, and through the sneeze or cough of an infected individual. The primary form of contracting polio is through fecal-oral transmission. A person can have feces on their
