[00:01.51]In the 1330's,the bubonic plague returned, [00:05.22]this time in Asia. [00:06.72]It would spread rapidly and come to be known [00:08.90]as"The Black Death". [00:10.86]The conditions in much of Asia and Europe- [00:14.10]war,climate change,a lack of adequate food, [00:17.52]crowded cities and a lack [00:19.05]of basic health routines- [00:20.99]provided the perfect conditions [00:22.92]for the disease to spread worldwide. [00:25.64]In highly populated areas all over Europe, [00:28.04]Asia,Africa and the Middle East, [00:30.61]one half to one third of the population [00:33.35]was lost to the Black Death. [00:35.10]Less populated areas,mostly in northern Europe, [00:38.34]were less severely affected. [00:40.68]Another epidemic that started [00:42.26]and spread in similar conditions [00:44.26]was the Great Flu Epidemic of 1918 [00:47.62](also called the Spanish Flu). [00:49.86]It struck near the end of the first World War [00:52.36]and continued after the war was finished. [00:55.06]Having killed between 25 and 50 nmillion people [00:58.60]in 18 months,it is believed tobe the most [01:00.99]acute worldwide epidemic in history. [01:04.50]More people died of the flu than died [01:06.66]in the war. [01:07.71]Yet,somehow,it has been forgotten by history. [01:11.29]One epidemic that we haven't forgotten yet [01:13.83]is the SARS epidemic of 2002/2003. [01:18.97]It began with an abnormal lung disease [01:20.89]in Guangdong Province [01:22.63]and spread worldwide after [01:24.31]Dr Liu Jianjun to Hong Kong. [01:26.15]
