We are always under the impression we are strong， but in fact life is extremely fragile.
The Ebola virus is one hundred times thinner than a human hair and only visible to us under a microscope， yet we are totally defenseless against it.

In Africa,  people living in jungles or near rivers can easily become targets of this deadly virus， and few ways exist to completely avoid infection， no matter how careful you are. This frightening tropical disease is extremely powerful. Once it breaks down the immune system， it launches a sweeping attack on all the organs and other t：issues of the body， sparing only the bone and muscle； nothing can stop it. It rapidly multiplies within the human body. The patient's blood cells begin to die and congeal under this ferocious attack， clogging veins and arteries and cutting off the blood supply to the whole body. Infected organs immediately show signs of fail-ing， before completely ceasing to function. At this stage, the viral proteins launch a relendess and overwhelming attack on all fronts，successively causing subcutaneous hemorrhaging， original hemor-thaging， and membrane rupture between skin and muscle， until the patient's life ends. However， this unusual and gruesome process is just the beginning of this evil virus's attempt to destroy the human species.
The patient's death does not spell the end of the virus. It can lurk in a decomposing body for hundreds of hours， multiplying while awaiting more victims. As is customary in some parts of Africa， when a dead person is about to be buried， his friends and relatives need to touch his body for a while； moreover， his relatives will cut open his abdomen to remove the viscera， putting all those involved in the process at huge risk. It is at this point that the viral legions come out in search of more victims. Needless to say， the biological resistance people can put up is completely futile， and there is no way they can escape the virus's grasp. Eventually, they die， one by one， gruesomely and humiliatingly. Forty years ago， in late September 1976， a cultured missionary，Mabalo Lokela， died from Ebola in exactly this manner. This was the first documented case of a patient universally recognized to have died from Ebola. Although honor and dignity were things that he had valued highly in life， he held onto neither as his end neared.
"Blood was oozing from his eyes， nose， mouth， ears， anus， and ure-thra； he had skin ruptures， and shrunken， crooked limbs... He looked more frightening than even ghosts and monsters，" said one of his students.
