Polio virus essay

Although it is rare to see someone suffering from the disease, in some countries, such as Nigeria, Pakistan, and Afghanistan, the virus still exists. There is no cure, but it is not infectious or contagious. Under objective 2 of the Eradication and Endgame Plan, at least one dose of inactivated poliomyelitis vaccine IPV should be introduced into all routine immunization programmes globally, and trivalent oral polio vaccines tOPV will be replaced with bivalent bOPV in all OPV-using countries.

It is then shed into the environment through the faeces where it can spread rapidly through a community, especially in situations of poor hygiene and sanitation. Extensive media coverage of polio outbreaks led to nationwide hysteria, prompting the race for a cure. Polio is an extremely contagious virus that attacks the nervous system, starting in the lower spine and moving slowly up the spinal column. The virus stays within the intestines, before spreading to other areas of the body.

People who receive OPV may shed the virus and can infect others, especially those who are not vaccinated. This includes the very young, pregnant women, and those with immune systems that are substantially weakened by other medical conditions.

Vaccine There are two vaccines available to fight polio: inactivated poliovirus IPV oral polio vaccine OPV IPV consists of a series of injections that start 2 months after birth and continue until the child is 4 to 6 years old.

Polio causes

Some theorist believe that it was more common for a infant that was passed the age of six months to develop poliomyelitis because Poliomyelitis is a contagious viral disease that is transmitted via person to person contact the mouth and than multiplies in the gastrointestinal tract.

In areas with poor sanitation, the virus easily spreads from feces into the water supply, or, by touch, into food. They include spinal polio, non-paralytic form, and paralytic polio. It caused fear and hysteria, confusion and anger, paralysis, and even death. Currently there is no cure for the. There are many books written about the disease and how it was controlled. There is no cure for polio, only treatment to alleviate the symptoms. Under objective 2 of the Eradication and Endgame Plan, at least one dose of inactivated poliomyelitis vaccine IPV should be introduced into all routine immunization programmes globally, and trivalent oral polio vaccines tOPV will be replaced with bivalent bOPV in all OPV-using countries.
