In August 1967, a viral haemorrhagic fever similar to Ebola hit the quiet university town of Marburg in what was then West Germany. The case fatality rate of over 20 per cent wasn’t quite on a par with the Black Death, but it was bad enough. Luckily, the initial outbreak affected only twenty-five people and was quickly contained, so total cases were limited to thirty-one and total deaths to seven. Germans, it seems, have a healthy aversion to contact with the body fluids of dying relatives, and hospitals were sufficiently well-equipped to safely handle infectious patients oozing their insides out. One laboratory technician did however fall sick after he cut himself during an autopsy on a patient who had died of the disease. Accidents will happen, even to Germans.
The mystery illness came to be known as Marburg Disease, back in the days when it was still socially acceptable to name diseases after the places where they first appeared. Its source was traced to a batch of African green monkeys that had been shipped from Uganda for use in polio research. At the time, it was uncertain whether Marburg Disease had originated in Uganda, or the monkeys had become infected en route. That’s because the monkeys had flown to Germany via Heathrow, and thus their trip was inevitably held up by strike action. During their involuntary two-day layover, they came into contact with animals from around the world, their British handlers, and the local rats, raising the possibility of cross-infection. Consider that the next time you fly through Heathrow.
The Lancet was the first medical journal to publish a paper identifying the cause of Marburg Disease, going to press with an explanation just three months after the first victims fell ill. True to form, they got it wrong, blaming a bacterial agent. Slower, more careful research revealed that the real cause was a virus.
What was known at the time, and has now been known for more than half a century, is that Marburg Disease escaped from a biological laboratory. But you wouldn’t know that from the World Health Organisation website entry for Marburg Disease, or even from the Wikipedia page. The Australian Department of Health is more forthcoming, noting that the laboratory workers had been exposed to tissue samples from monkeys, but draws no particular conclusions from that fact. And why should they? Question the safety of one laboratory, and you question the safety of all.
