The Coming Plague of Slums

Against the Current, No. 109, March/April 2004

MASS DEATH MAY be coming to a neighborhood near you, and the Department of Homeland Security will be helpless to prevent it. The terrorist in this case will be a mutant offspring of influenza A subtype H5N1: the explosively spreading avian virus that the World Health Organization (WHO) worries will be the progenitor of a deadly global plague.

The most lethal massacre in human history was the 1918-19 influenza pandemic that culled more than two percent of humanity (40-50 million human deaths) in a single winter. Although it was never proven, many researchers believe that the pandemic was caused by a bird virus that exchanged genes with a human strain and thus acquired the ability to spread easily from person to person. Humans have little immune protection against such species’ jumps.

The biological reservoir of influenza is the mixed agriculture of southern China where wild and domestic fowl, pigs (another influenza vector) and humans are brought into intimate ecological contact in farms and markets.

Breakneck urbanization, a soaring demand for poultry and pork, and what the journal Science recently characterizes as “denser concentrations of larger poultry farms without appropriate biological safeguards” create optimum conditions for the rapid evolution of viruses and their promiscuous passage from one species to another.

Influenza, indeed, is like a viral fashion industry: every winter changing styles (glycoprotein coats) to create new strains, but then, perhaps every thirty years, undergoing a revolution (species jump) that unleashes a virulent pandemic.

The last pandemic killed half a million people in 1968, but scientists interviewed in Nature and Science expressed fears that H5N1 might be on the verge of evolving into something more like the 1918-19 monster.

Although so far it has only been transmitted by direct contact with birds and especially their droppings, the current strain is far more lethal than last year’s SARs epidemic that caused so much international havoc. As a result, a top researcher told Nature, “everyone’s preparing for the worst-case scenario.”

Moreover, H5N1 is spreading at a much higher velocity than previous avian flus (there have been outbreaks annually since 1997). This phenomenon puzzled WHO researchers until they discovered that migratory birds are dying in large numbers across Asia. (It is chastening to recall that West Nile virus, also a bird disease, was able to fly across the Atlantic.)

H5N1’s progress has also been abetted by poor monitoring and government secrecy in half a dozen countries, but especially in Thailand and China. The Chinese staunchly deny covering up an avian epidemic as they did SARs, but the eminent virologist Kenneth Shortridge, interviewed by Science (23 January), said all evidence points to “natural reservoirs in southern China” where the disease
might have emerged as early as last October.

Poverty and Pandemics

This winter’s moderate flu epidemic, which overwhelmed emergency rooms and quickly used up supplies of vaccine, vividly demonstrated how ill-prepared even the richest countries are to deal with an imminent pandemic (i.e. mass outbreak of a new disease). Current vaccine production lines, which depend upon a limited supply of fertile hen eggs, couldn’t meet even a fraction of potential demand.

But a true pandemic would probably overwhelm the world long before a vaccine could be developed and produced in large quantities. The potential accelerators of a new plague are the huge slums of Asia. Concentrated poverty, indeed, is one of the most important variables in any model of how a pandemic might grow.

The bustees of Kolkata, the chawls of Mumbai, the kampungs of Jakarta, or the katchi abadis of Karachi are, from an epidemiological standpoint, landscapes saturated in gasoline and awaiting an errant spark like H5N1. (Twenty million
or more of the deaths in 1918-19 were in poor, congested and recently famished parts of British India.)

Last fall the United Nations Human Settlements Program published a historic report, The Challenge of Slums, which warned that slums across the world were growing in their own hothouse, viral fashion. One billion people, mainly uprooted rural migrants, are currently warehoused in shanty towns and squatters’ camps, and the number will double in the next generation.

The authors of the report broke with traditional UN circumspection to squarely blame the International Monetary Fund and its neocolonial “conditionalities” for spawning slums by decimating public-sector spending and formal employment throughout the developing world.

One of the principal targets of IMF austerity programs has been urban public health in large third world countries. In Zaire and Ghana, for instance, “structural adjustment” meant laying off tens of thousands of public health workers and doctors. Similarly in Kenya and Zimbabwe, implementation of IMF demands led to huge falloffs in health care coverage and spending.

Thanks to global neoliberalism, then, disease surveillance and epidemic response are weakest precisely where they are most important: in the mega-slums of Asia and Africa. That’s where the brushfire of H5NI could turn into a deadly biological firestorm.

In the event, it would consume more than just the poor. Once a new pandemic had acquired the momentum of mass mortality in Asia it would inexorably spread to North America and Europe. It would easily climb the walls of gated communities and other fortresses of privilege.

Here, of course, is the rub. In the past, the rich countries, with few exceptions, have shown callous indifference to the monstrous human toll of AIDS in Africa or the two million poor children annually claimed by malaria. H5N1 may be our unexpected reward.
