Killed 3 million people between 1918 and 1922 alone, and most of Napoleon's soldiers on Russia.
Typhus is any one of several similar diseases caused by louse-borne bacteria. The name comes from the Greek typhos, meaning smoky or lazy, describing the state of mind of those affected with typhus. Rickettsia is endemic in rodent hosts, including mice and rats, and spreads to humans through mites, fleas and body lice. The arthropod vector flourishes under conditions of poor hygiene, such as those found in prisons or refugee camps, amongst the homeless, or until the middle of the 20th century, in armies in the field.

The first description of typhus was probably given in 1083 at a convent near Salerno, Italy. Before a vaccine was developed in World War II, typhus was a devastating disease for humans and has been responsible for a number of epidemics throughout history. During the second year of the Peloponnesian War (430 BC), the city-state of Athens in ancient Greece was hit by a devastating epidemic, known as the Plague of Athens, which killed, among others, Pericles and his two elder sons. The plague returned twice more, in 429 BC and in the winter of 427/6 BC. Epidemic typhus is one of the strongest candidates for the cause of this disease outbreak, supported by both medical and scholarly opinions. Epidemics occurred throughout Europe from the 16th to the 19th centuries, and occurred during the English Civil War, the Thirty Years' War and the Napoleonic Wars. During Napoleon's retreat from Moscow in 1812, more French soldiers died of typhus than were killed by the Russians. A major epidemic occurred in Ireland between 1816-19, and again in the late 1830s, and yet another major typhus epidemic occurred during the Great Irish Famine between 1846 and 1849.
In America, a typhus epidemic killed the son of Franklin Pierce in Concord, New Hampshire in 1843 and struck in Philadelphia in 1837. Several epidemics occurred in Baltimore, Memphis and Washington DC between 1865 and 1873. During World War I typhus caused three million deaths in Russia and more in Poland and Romania. De-lousing stations were established for troops on the Western front but the disease ravaged the armies of the Eastern front, with over 150,000 dying in Serbia alone. Fatalities were generally between 10 to 40 percent of those infected, and the disease was a major cause of death for those nursing the sick. Following the development of a vaccine during World War II epidemics occur only in Eastern Europe, the Middle East and parts of Africa.
