How India has had remarkable success in polio fight

One by one the young children open their mouths to receive the two drops of polio vaccine. Then they hold out their hand to get their "purple pinky" - one finger painted with indelible purple ink to show they've been immunised.

Some of the children try, and fail, to suck off the ink because they want to get another toy - some stickers, a balloon or pencil - as a reward for coming to the booth.

There are 7,000 impromptu vaccination booths across the capital. Across India, these regular National Immunisation Days aim to reach more than 170 million children under five - the group most at risk from polio. I'm here to witness India's successful fight against polio.

Several of the booths in Delhi are staffed by volunteers from Britain; they are all members of Rotary - the worldwide network of clubs of business and community volunteers.

The Rotary volunteers - wearing bright yellow shirts - attract a lot of attention. Veronica Stabbins, from Windsor in Berkshire, is here with her husband Adrian - they immunise around 200 children in two hours.

She said: "This is our third visit to India volunteering for Rotary. It is wonderful to be part of trying to eradicate this dreadful disease. When we go home we try to raise awareness of what still needs to be done."

Another Rotary member, Jenny Schwarz from Merseyside, said: "I've been raising money to fight polio for 25 years. My dream is to have a polio-free world."

All the Rotary volunteers - there are more than 40 of them from Britain, and 500 from around the world - pay all the expenses of their trip and then often use the experience to do further fund-raising at home.

Remarkable achievement

India used to be the epicentre of polio. In 1985, there were an estimated 150,000 cases in India and as recently as 2009 there were 741, more than any other country in the world.

The world is now at a crossroads - it can build on the success of immunisation in India which has been polio-free for a year.

If it does not, the risk is the virus will re-establish itself here and in other countries.

But its last case was in January 2011 - a remarkable achievement. But it won't be officially removed from the list of polio endemic countries until the result of lab tests confirm that it is no longer to be found in sewage.

That confirmation is expected in the next few weeks. It will leave three endemic countries: Pakistan, Afghanistan and Nigeria where the virus has never been under control. All saw an increase in cases last year.

The success in India has been achieved through a partnership between the Indian government, with support from the World Health Organization (WHO), Rotary, Unicef and with major contributions from the Bill and Melinda Gates Foundation.

Last year the UK government doubled its support to the Global Polio Eradication Initiative (GPEI).

Dr Mathew Varghese Dr Mathew Varghese described the stigma faced by children with polio

A visit to St Stephen's Hospital in Delhi offers a stark reminder why polio used to be one of the world's most feared diseases. Mohammad Zaid is 11 and he caught polio as a baby. The virus attacked the cells in his spinal cord, paralysing his legs which are now wasted.

He gets about by crawling, but is at the hospital for surgery. Mohammad will need four operations - to straighten each hip and knee - before he can be fitted with metal calipers so that he can finally walk.

Dr Mathew Varghese, head of orthopaedics, said children with polio don't just suffer physically: "Many of them drop out of school early and they face a stigma being disabled - and all this from a disease which can be prevented with a vaccine."

Polio history

Polio has been causing disability and death since ancient times.

There is an stone engraving from Egypt around 1400BC which shows a priest with a withered leg typical of paralytic polio.

The history of Polio Poliomyelitis has existed as long as human society, but became a major public health issue in late Victorian times with major epidemics in Europe and the United States. The disease, which causes spinal and respiratory paralysis, can kill and remains incurable but vaccines have assisted in its almost total eradication today.

When the virus was ubiquitous and entire populations were constantly being re-infected, the disease appears to have been comparatively rare.

Infants were infected at an early age when paralysis is less likely to occur.

Epidemics of polio were not recognised until the advent of improved sanitation and water supplies. This meant that there were sufficient numbers of people without immunity.

From the late 19th Century major outbreaks occurred in the summer months in the US and Europe.

The ability of the virus to cause crippling disability and death within hours meant polio became a greatly feared infection.

In the late 1920s the so-called iron lung was first used to help patients paralysed with polio to enable breathing.

The last per cent

There are two vaccines against polio. The first - an injected dose of inactivated (killed) virus - was developed by Dr Jonas Salk, and introduced in 1955.


  • Poliomyelitis is a highly infectious viral disease which affects the central nervous system
  • There are three strains of wild polio virus - type 2 has been eliminated in the wild
  • It is passed from person to person via contaminated faeces
  • Early symptoms include fever, headache, tiredness and stiffness in the neck
  • Most cases cause no symptoms but in around one in 200 infections it leads to irreversible paralysis, usually in the legs
  • A minority of serious cases are fatal when the chest muscles become paralysed and the patient is unable to breathe
  • Post-polio syndrome can develop decades after initial illness, causing muscle weakness and breathing problems
  • There is no cure for polio but it can be prevented
  • There are two types of polio vaccine, both of which can provide life-long protection - an oral vaccine, widely used in developing countries, and an injectable version
  • The first dose of the oral vaccine can cause paralysis in very rare cases (about 1 in 2.7 million children)

A second, oral polio vaccine was created in 1961 by Dr Albert Sabin using a live attenuated (weakened) strain of virus.

It has been this vaccine, given in drops, which has been the main tool of polio eradication.

Mass immunisation campaigns led to a dramatic drop in polio cases.

Rotary International created the PolioPlus programme in 1985 aimed at eradicating the disease.

Its members, known as Rotarians, have raised $1bn (
