Polio is a serious disease among children worldwide. But do you know that the World Health Organization (WHO) had declared India polio free. But once again polio patients have been confirmed in the country. Know when the World Health Organization (WHO) declared India polio free.
What is polio?
Now first of all, let us know what is polio virus? Let us tell you that polio virus is an infection. It is called poliomyelitis. When polio occurs, the brain and spinal cord get damaged. There is no cure for polio till date.
Declared polio free
Polio is one of the most serious diseases spread among children. Children become disabled due to polio. But India was declared polio free by the World Health Organization (WHO) in the year 2014, i.e. about 10 years ago. This is because the last case of this disease was reported in India in the year 2011. There was no case for three years after that.
When is a country declared infection free
According to the rules, if after vaccination, not a single case of the disease is reported in a country for three years, then that country is declared free from the disease concerned. This is why India became polio free in 2014. Because this disease was brought under control after the ‘Pulse Polio’ campaign that ran for many years.
Pulse Polio Campaign
Let us tell you that in this campaign, polio medicine was given to children. This campaign was run on a large scale across the country. But now after ten years, a case of polio has been registered in the country. Now the question is whether the World Health Organization (WHO) will again remove the polio free tag from India if the cases increase. According to the information, this does not happen if there are one or two cases, Indian scientists are investigating this.
Polio infection
This infection has been found in a two-year-old child in Meghalaya. This child had also been vaccinated, but still he got infected. But the question is that when the disease has been eradicated from the country, then how has the case of polio come again. Let us tell you that Professor Dr. L. H. Ghotekar of the Department of Medicine at Lady Harding Medical College says that this is not a case of normal polio but it is an incident of vaccine derived polio virus. This kind of situation occurs in case of some diseases. He said that this happens when a weak strain is put in the vaccine against the virus. At the same time, the dose of vaccine is not effective on the virus. Due to this the child gets infected.
