Ailing Populations Spell Ailing Economies By Douglas Birch, The Baltimore Sun Jeffrey D Sachs has made a career out of doctoring ailing economies. He has recommended huge doses of capitalism to cure the ills of former socialist economies, from Bolivia to Mongolia. He has prescribed austerity to cool the fever of quintuple-digit inflation. But in recent years, Sachs says, he has looked for deeper causes for economic malaise. For many nations, he says, malignant poverty might be primarily the product of wretched public health. Economists say, Reform the value-added tax. Get the budget deficit down. Open the borders, says Sachs, 45, head of the Harvard Center for International Development. That's great stuff if you happen to be Poland. But it's not the answer if you happen to be Tanzania, where you're suffering holo-endemic malaria, shistosomiasis [parasitic worms] and everything else you can imagine. So Sachs and a colleague, Michael Kremer of Harvard, have joined health advocates in lobbying Congress to set aside $1 billion in tax credits to nudge the world's pharmaceutical companies to develop vaccines against tuberculosis, AIDS and malaria, some of the world's biggest killers. Sachs started studying the links between geography, disease and poverty about five years ago. He was struck by one pattern. There are precious few people in the tropics that are rich, he says. And the people living in the temperate zones that are poor are usually poor for quite identifiable reasons, the dominant one of which is the Red Army. Sachs wonders what force plays the role of Marxist-Leninist doctrine in equatorial regions. One suspect is malaria. Though malaria is only one of several tropical diseases, it sets the pattern. The microbe loves hot, wet climates. It is transmitted by an animal or insect in this case a type of mosquito that is expensive or impossible to control in tropical regions. Because malaria was driven out of most industrial nations in the mid-1900s, there is relatively little research on it. Drug companies pay scant attention, because malaria's victims can't afford to pay for expensive new medications. As a result, malaria claims 1.1 million lives a year, most of them children in Africa. The disease's affects on economies are also extensive. In a recent study, Sachs' fellow Harvard economist John Luke Gallup found that countries with high levels of malaria had incomes one- third of those without malaria. There are huge negative economic effects of having...malaria, Sachs says. And huge positive effects of getting rid of it. Until the late 1940s, Italy suffered 300,000 cases and 20,000 deaths a year from malaria, but a campaign to drain wetlands and spray mosquitoes wiped the disease out. That country's economy took off, growing five times faster than it had in previous decades and faster than those of the rest of Western Europe. Malaria's impact on countries such as Botswana, Tanzania and Nigeria is unrelenting. The disease doesn't just keep millions home from work and school every day. Chronic anemia or attacks of cerebral malaria can cause lifelong problems with learning and memory. Though they lack statistics, Sachs and Gallup suggest malaria discourages tourism, foreign investment and trade. It might prevent people with university educations, who live in mosquito-free cities, from working in the countryside. The burden of tropical disease, Sachs says, could help explain why some parts of the world have become increasingly wealthy while others have remained poor. Residents of the world's richest countries had average incomes three times higher than those in poor countries in 1830. Today, the average American or European earns 20 times more than the average resident of sub-Saharan Africa. Sachs doesn't blame the rich countries for that gap. Everybody started poor, and a part of the world got rich. It's not that everybody was rich and a part got poor through exploitation. Rapid advances in Western science haven't helped tropical regions because most technology wasn't designed to work in warm, wet regions. Factory farming techniques common in the US Midwest can't be used in the Congo river basin. Modern medical research is still primarily focused on diseases common in the US, Europe and Japan. Poor nations can do only so much for themselves, Sachs says. Wealthy nations have to help. Technology is advancing faster than at any other time, and fortunes are being spent on the problems facing the industrial world, he says, but almost nothing is going into problems that are strictly the problems of tropical societies.
