Just over a fortnight ago, 27th March saw India declared a Polio-free country; it has been over three years since 18 month-old Rukhsar Khatoon was diagnosed with the last case in South-East Asia. The disease left her with mild paralysis in her right leg.

Only three decades ago, 200,000 children per year were left with disabilities due to polio in India, and in 2009 India was still the site of 741 of the world’s 1,604 cases. Now, following the elimination of polio from India, 80% of the world is polio free. [1] The final push will involve mass vaccination of remaining endemic countries: Afghanistan, Niger and Pakistan, but with one-hundred children recently infected in Syria there is a race to prevent new epidemics before the 2018 eradication target. [2]

The Polio virus will not be the first pathogen to be eradicated by human intervention. The Variola virus (the causative agent of smallpox) has been extinct in the wild since 1977, and more recently in 2011, the Rinderpest virus was declared eradicated by the OIE. [3] The successful Smallpox campaign cost $1billion in today’s currency, with two-thirds of the financial burden on the endemic countries; this is in stark contrast to the polio programme with the Post Graduation Education Institute (PGEI) estimating that the next four years will cost $5.5 billion in addition to the billions already invested since the 1980s. Yet there is still a strong economic case for eradication, with returns of $25 billion in as few as two decades when compared to routine immunisation. [4]

So what does polio elimination have to do with Neglected Tropical Diseases (NTDs)? Like the polio virus, many of the pathogens that cause NTDs are eradicable; they cause debilitating symptoms that hinder economic and social activity; they cause much suffering to the afflicted and their families; in total, 1.7 billion people are at risk of developing these diseases. Of the 17 NTDs listed by the WHO, two are set to be eradicated worldwide and 10 have co-ordinated programmes to eliminate the disease from endemic populations, all within the next 10 years. [5]

In 2004, another disease was eliminated from India to a much smaller fanfare; Yaws begins as a cutaneous infection and spreads to cartilage inflicting disfigurement and disability. The causative pathogen, a bacterium of the Treponema pallidum species, is easily treated with a single oral dose of azithromycin and yet Ghana, Papua New Guinea and the Solomon Islands report over 10,000 cases per year. WHO hopes for its eradication by 2020 through a programme of identification of endemic areas and blanket treatment. [5]

The NTD policy team members of Polygeia are working hard to find areas where we can take novel ideas and apply them effectively to real world situations. My personal interests lie in the use of mobile phones and SMS to improve uptake of available testing, counselling and treatment concordance. Much work has been done in HIV and TB treatment with schemes such as WelTel showing promise. Under this programme, HIV positive patients were required to respond to weekly texts from a nurse and then outcomes were compared to a control group receiving standard care. Those receiving texts were 19% less likely to be non-compliant and 16% less likely to show failure of viral suppression. In other words, for every 11 people treated, one would remain well who may otherwise have developed AIDS. [6]   We hope to develop policies that will take successful concepts in eMedicine to the fight against NTDs.

How a Polio-Free India could Pave the way for an NTD-Free India

Monday marked the three-year anniversary of the last reported polio case in India — a landmark achievement for a country that reported the highest number of polio cases in the world in 2009. A formal declaration of India as polio-free is expected later this year by the World Health Organization (WHO).

According to the Global Polio Eradication Initiative, India was once thought to be the most difficult country in which to achieve polio eradication.  Today, 71 percent of children in India have received the polio vaccine, and India has become one of the world’s largest donors to global polio eradication as reported by Time magazine.

India’s successful polio eradication program illustrates the leadership role that India can take in the global effort to control and eliminate neglected tropical diseases (NTDs).  Similar to polio eradication programs, successful NTD control and elimination programs rely on well-organized and large-scale mass drug administration and surveillance activities. India’s national lymphatic filariasis elimination program reaches more than 300 million people each year, making it the world’s largest NTD program. India has a long history of ending the suffering caused by many communicable diseases, including smallpox, guinea worm and yaws. These remarkable achievements have been possible because of the concerted efforts and commitment of leaders in the Indian government and across civil society.

Despite these successes, India needs to do much more to achieve national and global NTD control and elimination goals.  India accounts for 35 percent of the global burden of all NTDs, and currently less than half of the population living at risk for these diseases is being reached by mass drug administration programs. India must reinforce its commitment to eliminate NTDs like lymphatic filariasis, trachoma, kala azar and leprosy, and ensure that the necessary resources and capacity exist to scale-up and sustain operations until control and elimination goals are met.

Three years polio-free demonstrates that India has the expertise, capacity and resources to be a world leader in ending the burden of NTDs. There will be human and financial resources freed up from this victory ready to be channeled with renewed enthusiasm and determination to the fight against NTDs. India is a striking demonstration that elimination is possible.  By reducing the NTD burden within its borders, India can contribute to a big reduction in the global NTD burden and its example will be an extraordinary push for all the countries still affected.  As we celebrate India’s contribution to the global fight against polio, let’s also encourage continued leadership and success on NTDs to reach the World Health Organization 2020 goals.

Global Health Giant Joins Fight to Eliminate Polio

Shortly after Bill Gates’ “Polio and the Power of Vaccines” event—where Mr. Gates and a panel of experts including Sabin Executive Vice President Dr. Ciro de Quadros issued a renewed call to eliminate polio—one global health giant was quoted strongly opposing global polio elimination efforts.

As New York Times reporter Donald McNeil notes in this article published yesterday, “why does it matter what one particular expert thinks? Because, for better or worse, the mantle has been wrapped around the venerable 82-year-old Donald A. Henderson that he is “The Man Who Wiped Out Smallpox.”

Thankfully, Mr. McNeil’s article goes on to report how the esteemed Dr. Henderson has changed his opinion on the important matter of polio eradication. And the reason behind Dr. Henderson’s 180 is a conversation with Dr. de Quadros.

“The Man Who Found the Last Case of Smallpox in Ethiopia and Chased Polio and Measles Out of the Western Hemisphere,” aka Dr. de Quadros, was able to convince “The Man Who Wiped Out Smallpox” that Mr. Gates is committed to eradicating polio and that vaccine technology has advanced considerably, among other things.

Now, with Dr. Henderson on board, the global health community can forcefully move ahead with adding polio to the list of the diseases eliminated from humanity.

Eliminating Polio is within Our Reach

As we begin another year in the battle against polio, I am optimistic that eliminating this disease from the face of the planet is within our reach. Over the last 30 years, global health efforts have pushed polio to the brink, reducing its prevalence by 99 percent. Thanks to these efforts, the disease remains endemic in only a handful of countries, yet steep challenges remain as we work toward eradication.

Within four countries – India, Nigeria, Pakistan, and Afghanistan – polio has proven to be a persistent foe, continuing to paralyze and take the lives of young children despite our best efforts. And as long as the disease remains, so does the threat of outbreaks, which can quickly spread across continents.

Just last year, the World Health Organization (WHO) reported an outbreak of poliovirus – imported from India – in Tajikistan, a country that had been certified polio-free since 2002. A similar Indian strain caused 201 cases of paralysis and 104 deaths in the Congo, causing health officials to scramble to re-vaccinate the entire population. Similar outbreaks occurred last year in Russia, Turkmenistan, Kazakhstan and Uzbekistan.
