when was the cure for the bubonic plague found
Bubonic plague Prevention is through public health measures such as not handling dead animals in areas where plague is common.[1] Vaccines have not been found to be very useful for plague prevention.[1] Several antibiotics are effective for treatment, including streptomycin, gentamicin, and doxycycline.[3][4] Without treatment, plague results in the death of 30% to 90% of those infected.[1][3] Death, if it occurs, is typically within ten days.[6] With treatment the risk of death is around 10%.[3] Globally there are about 650 documented cases a year, which result in ~120 deaths.[1] In the 21st century, the disease is most common in Africa.[1]
Black Death Plague was reportedly first introduced to Europe via Genoese traders at the port city of Kaffa in the Crimea in 1347. After a protracted siege, during which the Mongol army under Jani Beg was suffering from the disease, the army catapulted the infected corpses over the city walls of Kaffa to infect the inhabitants. The Genoese traders fled, taking the plague by ship into Sicily and the south of Europe, whence it spread north.[18] Whether or not this hypothesis is accurate, it is clear that several existing conditions such as war, famine, and weather contributed to the severity of the Black Death.
