A deadly new form of haemorrhagic fever was discovered in the small town of Marburg in West Germany in the summer of 1967. The first patients all worked at a factory in the town which made vaccines. In the course of their work they had all come into contact with blood or tissue from monkeys from East Africa who were infected with a disease similar to Ebola.
