Seventh Cholera Pandemic (1 янв 1961 г. – 1 янв 1975 г.)

Описание:

The seventh cholera pandemic was the seventh major outbreak of cholera and occurred from the years 1961 to the 1970s and has continued (though much diminished) to the present. The spread of the disease was helped by modern transportation and mass migrations. Mortality rates, however, dropped markedly as governments began modern curative and preventative measures. The usual mortality rate of 50% dropped to 10% by the 1980s and less than 3% by the 1990s.

Estimated Deaths: 50,000
