what percentage of europe's population died of the plague
Black Death The Black Death is estimated to have killed 30–60% of Europe's total population.[6] In total, the plague may have reduced the world population from an estimated 450 million down to 350–375 million in the 14th century.[7] It took 200 years for the world population to recover to its previous level.[8][9] The plague recurred as outbreaks in Europe until the 19th century.
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 it 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] The disease is most common in Africa.[1]
