Polio and Sanitation

KHAGARIA: On the sandy banks of Kosi river in north Bihar, a quiet crowd of several hundred people is waiting in the sizzling morning sun. A speck appears in the pale blue summer sky, rapidly growing in size — its a gleaming white helicopter. Within seconds it is hovering above the opposite bank, amidst the cornfields.

The crowd is awestruck at the monstrous machine as it settles down in billowing clouds of sand. Out comes the man everybody has been waiting to see — Bill Gates.

Bill Gates has come to find out why polio eradication is failing in Bihar. He asks questions about immunization strategies and tries to figure out what sort of technical problems are blocking universal vaccine delivery.

People complain of lack of basic health facilities…There are only 49 auxilliary nurse and midwives under the PHC, against a sanctioned strength of 76…So, the delivery of basic health services is itself a distant dream…The villagers hope against hope. Isn’t the spread of polio linked to lack of sanitation and basic health facilities? Gates acknowledges this fact but says that it is for the government to do the needful. “We are concentrating on the eradication of polio, which is achievable through vaccines,” he says. [1]

Polio epidemics first appeared in the mid-nineteenth century. Many doctors and scientists struggled with the mystery: why, as living conditions improved, did incidents of paralysis increase? Out of all the changes that came with modernity, improved sanitation was chosen as the change which caused polio to turn from a mild illness to one that left death and permanent damage in its wake.  Here is an excellent example  from a 2007 medical article which summarizes the concept:

Prior to the 20th century, virtually all children were infected with PV while still protected by maternal antibodies. In the 1900s, following the industrial revolution of the late 18th and early 19th centuries, improved sanitation practices led to an increase in the age at which children first encountered the virus, such that at exposure children were no longer protected by maternal antibodies. Consequently, epidemics of poliomyelitis surfaced . [2] Read more

Polio and Acute Flaccid Paralysis

In post one of this series on polio, a term was introduced: “Acute Flaccid Paralysis”. [1]

Acute Flaccid Paralysis is a term which applies to the exact clinical symptoms you would expect to see from poliovirus infection, but which are not necessarily caused by polioviruses. Paralytic polio is actually considered a sub-category in the broad umbrella of acute flaccid paralysis. See pages 300-312 [1] for a chart and summary of many other causes of AFP, a few of which are: Guillaine-Barre syndrome, Cytomegalovirus polyradiculomyelopathy, Acute transverse myelitis, Lyme borreliosis, nonpolio enterovirus and Toxic myopathies.

For many years the medical profession assumed that when they saw paralysis with a particular cluster of symptoms, it was poliomyelitis. The 1954 Francis Trials of the Salk vaccine [2] triggered a reconsideration of this assumption, and a major change in the diagnostic criteria.

How were polio cases counted in 1954?

In 1954 most health departments worked with the WHO definition:

“…Signs and symptoms of nonparalytic poliomyelitis with the addition of partial or complete paralysis of one or more muscle groups, detected on two examinations at least 24 hours apart.” [3, p. 88]

How were polio cases counted in 1955?

In 1955 the criteria were changed to conform more closely to the definition used in the 1954 field trials: residual paralysis was determined 10 to 20 days after onset of illness and again 50 to 70 days after onset. [3, p. 88]

Thus, simply by changes in diagnostic criteria, the number of paralytic cases was predetermined to decrease in 1955-1957, whether or not any vaccine was used. At the same time, the number of nonparalytic cases was bound to increase because any case of poliomyelitis-like disease which could not be classified as paralytic poliomyelitis according to the new criteria was classified as nonparalytic poliomyelitis. Many of these cases, although reported as such, were not non-paralytic poliomyelitis. [3, p. 88] (emphasis added)

It was after the SALK vaccine was introduced, when fully vaccinated people continued to get “polio”, that doctors started looking a lot more carefully at the viruses in individuals. Many viruses were found to cause paralysis, for example coxsackie B, enterovirus 71, etc. Read more

Medical Double Standards in the Third World

    When it comes to third world medicine we almost invariably hear from the WHO about the successes of massive vaccination programs. If you look into the recent agenda for the World Health Assembly [1] you will find pandemic influenza vaccines at the top of the technical matters, and in the status section, the eradication of Poliomyelitis is at the top of that section. What is glaringly absent is a discussion of the pervasive double standards in research ethics, health-care safety and professional rigor that exist in the developing world. The WHO and its medical partners won’t talk about it publicly because when you look at the numbers, it is directly implicated in the suffering and ultimate death of millions of people in the developing world. That is what we’ll cover in this piece.

    It is well known that needle re-use can be a major cause of virus transmission. In 2000, a WHO press release states:

    Unsafe Injection practices have serious large-scale consequences…”unsafe injection practices throughout the world result in millions of infections which may lead to serious disease and death. Each year over-use of injections and re-use of dirty syringes and needles combine to cause an estimated 8 – 18 million hepatitis B virus infections, 2.3-4.7 million hepatitis C virus infections and 80,000 – 160,000 infections with HIV/AIDS worldwide. [2]

    That same press release uses an epidemic of Hepatitis C that occurred from Schistosomiasis treatment in Egypt. Notably absent is any discussion of the massive immunization campaigns waged throughout the third world coincident with the massive epidemics of HIV and other infectious diseases. However, someone there must be aware of the potential problem because the press release states the following at the end:

    In addition, to ensure the safety of immunization injections, WHO, the United Nations Children’s Fund (UNICEF), the United Nations Population Fund (UNFPA), and the International Federation of the Red Cross and Red Crescent Societies (IFRC) have recently called for the exclusive use of auto-disable (AD) syringes for immunization by the end of 2003.[2]

    We know quite reliably that the WHO knew years prior to this press release (2003) that medical practices in the developing world were problematic. As Gisselquist outlines in his 2009 article [3] the WHO was quietly giving UN employees the following advice in 1991.

    take special precautions to avoid HIV transmission via blood . . . If you are not carrying your own needles and syringes, avoid having injections unless they are absolutely necessary . . . Avoid tattooing and ear-piercing. Avoid any procedures that pierce the skin, such as acupuncture and dental work, unless they are genuinely necessary. Before submitting to any treatment that may give an entry point to HIV, ask whether the instruments to be used have been properly sterilized.[3]
