What is Poliomyelitis?
Poliomyelitis, commonly shortened to polio, is an infectious disease caused by the poliovirus. A virus that may cause paralysis and is easily preventable by the polio vaccine. In about 0.5 percent of cases, it moves from the gut to affect the central nervous system and there is muscle weakness resulting in a flaccid paralysis. This can occur over a few hours to a few days.
Lets know more about it in detail about Poliomyelitis:
Pathogen : Polio Virus
Mode of transmissions : Virus enters inside the body through food or water.
Incubation period : 7-14 day
Symptoms (i) The virus multipliesin intestinal cells and then reaches
the brain through blood.
(ii) It damages brain and nerves and causes infantile paralysis.
(iii) Stiffness of neck, fever, loss of head support.
Prevention and Cure:
Polio vaccine drop (oral polio vaccine, OPV) are given to children at certain intervals. Pulse polio programme is organised in our country to give polio vaccine to children
Some questions which are asked generally:
Q1.How many types of polio vaccines are there?
Polio vaccines are vaccines used to prevent poliomyelitis (polio). Two types are used: an inactivated poliovirus given by injection (IPV) and a weakened poliovirus given by mouth (OPV). The World Health Organization (WHO) recommends all children be fully vaccinated against polio.
Q2.Does polio vaccine last for life?
It doesn’t matter how long it has been since the earlier dose(s). Adults who are at increased risk of exposure to poliovirus and who have previously completed a routine series of polio vaccine (IPV or OPV) can receive one lifetime booster dose of IPV.
Q3.Can you still get polio if vaccinated?
No, thanks to a successful vaccination program, the United States has been polio-free for more than 30 years, but the disease still occurs in other parts of the world.
