The first case of Ebola raised its ugly head in 1976 in Zaire, Africa. It remained dormant until 1995 when it struck again. This time the virus was traced to one family. Several years ago I saw a documentary on that family (the Menga family). Maybe some of you remember it too. Gaspard Menga was the first to contract Ebola that year. Of the 23 members of the extended Menga-Nseke family, 13 died of Ebola between Jan. 6 and March 9, 1995. 4 died in Kitwit hospital and the deadly virus is suspected to have lurked there two months before erupting in mid-April when surgery on an infected lab technician spread Ebola to a dozen doctors and nurses. Before it was all over, some 120 people died.
