This epidemic has spread throughout the world. At least 40 million people became victims of it. It was the most terrible epidemic in the history of mankind. In Europe, killed 20 million people (a quarter of the population). New time brought new diseases. Cholera, typhus, influenza, measles and smallpox - for the XIX-XX centuries. In total, these diseases have been ill with billions of people.
The epidemic of the so-called "Spanish flu", swept across Europe in 1918, is considered the most terrible in modern history of mankind - then about 50 million people died from the flu. Nowadays plague of the XX century. called HIV infection. Surprise is not so much the extent of the spread of infection, how many unpredictable features of its development. The cases of detecting the symptoms of AIDS in a number of homosexuals date back to the late 1970s. In the early 80's. the etiologic factor of AIDS was identified, and the disease assumed the scale characteristic for the onset of the epidemic. The first person with classic symptoms of AIDS died in 1959.
