This engaging account sketches the investigation and quest for a cure for the "mal 'aria" of Rome. "Mal 'aria" was once thought to emanate from the "bad air" of swamps and marshes. Rocco, herself a victim of this dread illness, narrates its impact from ancient times into the modern world. When the death of a pope brought 55 cardinals to Rome to replace Gregory XV, 10 of them had contracted malaria within two weeks. Those who survived returning to Sees in European nations spread further a malady already prevalent in many nations as distant as the British Isles and Scandinavia. Even as the papal successor, who was also prostrated with chills and fever, struggled to survive the infection, some of his minions were advocating a likely cure against great skepticism.
Jesuit missionaries in the New World discovered Native Americans using a powdered tree bark to treat fevers and "agues". Sending the powder back to Catholic Europe introduced the first therapy for malaria, probably just as these same interlopers were infesting the Western Hemisphere with the parasite. Cinchona powder, diluted in wine to cover its bitterness, verged on the miraculous. As Rocco describes its effect, she also recounts the resistance to the "Jesuit powder" in Protestant Europe, particularly Britain. Lack of enthusiasm, plus military ineptness, led to a malarial onslaught in 1808, when an English attempt to invade Napoleon's empire ended in disaster.
Empire, war and malaria remained in close company throughout the 19th Century. British incursions into west Africa were stalled by the infection. At one point the medical records indicated more cases of malaria than there were settlers - due to repeat hospital patients. Even against this severity, progress was being made. It's said "there's always one" and Rocco shows how one dedicated man made an immense difference. On a voyage up the Niger, Baikie imposed a strict daily regimen of quinine dosage. One of his crew was murdered and one drowned - but none were lost to malaria.
Returning to the Western Hemisphere, Rocco describes the inept handling of fevers by the in the American Civil War. Vicksburg, she asserts, failed to be taken due to the Union's lack of quinine for its troops investing the city. Even greater disaster awaited the French in their attempt to link the Atlantic and Pacific with a Panama Canal. Instead of treating the workers, the French merely hid the casualty list and hired replacements. Even as late as World War II, battlegrounds in the Pacific highlighted the need for plentiful supplies of quinine. By that time, however, some synthetics had been developed. Malaria, however, is neither easily diagnosed nor treated. Rocco notes that there are several versions of the illness, and many varieties of cinchona. Matching them takes skill.
At the end of the 19th Century, malaria had been identified as a parasite, not the effusion of swampy fumes. Rocco describes the labours of British Army doctor Ronald Ross, who laboured under appalling conditions in India. He traced the course of the parasite, in part by dissecting mosquitoes with a razor blade! This new understanding led to more directed treatment, and, ultimately, a Nobel Prize for Ross. Rocco's diagram of the life cycle of the parasite suggests the complexity of the problem of diagnosis and therapy.
Rocco concludes with a reminder that malaria identified is not malaria eliminated. It kills millions of children every year and prostrates whole communities. South American forests were denuded by exploiters seeking the bark. The synthetics developed proved a temporary solution since the parasite appears to have evolved resistance to them. Today's chief source of natural quinine is a threatened forest in war-torn central Africa. She describes the travails of a firm struggling to maintain supply. The picture would be encouraging if the firm obtained support from industrial nations. That hasn't been forthcoming.
Rocco's opening sentence, "My grandparents had been married for many years when they left Europe for Africa - although not to each other" sets the tone of this book. Her personalised narrative form skips the use of footnotes, but there are Notes on Sources and a Further Reading list. A collection of photos and maps adds reference.
