A study of the ebola hemorrhagic fever

Ebola virus disease, first recognized in in the Democratic Republic of the Congo, is a serious and often fatal illness in humans and nonhuman primates caused by infection with one of five Ebola virus species four of which can infect humans. The virus is spread through direct contact with the bodily fluids of a sick person and can cause fever, headache, muscle pain, weakness, fatigue, diarrhea, vomiting, stomach pain and hemorrhage severe bleeding. Ebola virus is part of the Filoviridae family, which also includes Marburg virus.

This village, located five kilometers from Yambuku, was chosen for detailed analysis of disease transmission. The town was mapped and a door to door census revealed that persons were resident in 71 households prior to the epidemic Figure 5.

The first case was a 27 year old man who received an injection at YMH outpatient clinic on 29 August. Within six days, four more persons with a shitory of injection at the Yambuku Mission Hospital became ill.

During this same period two nurses, a medical assistant and a catechist contracted the disease. These persons had all been in frequent contact with patients at the hospital, but had not received injections. By mid-October 15 additional villagers had sickened, 12 of these secondary close contact with patients in this or other villages.

Seven of these contacts occurred in the home of a neighbour, and three were contacts of sick relatives in other villages.

Information on three cases was lacking. Ten cases were among males, 14 among females. Adults of years were most commonly affected. Only two persons survived, both contact infections. Four had secondary cases and one other had more than one case but could not be documented sufficiently to arrive at a conclusion as to transmission mode.

There were six secondary and three tertiary cases giving transmission rates of 7. Households with cases were scattered through the villages and no pattern of disease transmission other than very close patient contact was established. In December and Januarysera were sought from as many people as possible.

A total of serum samples were obtained. Three persons, two of them in clinically non-infected households, who had not had symptoms during or since the epidemic, were found to have Ebola virus IFA titres of at least 1: All three had experienced contact with fatal cases.

Extrapolating to the entire population two more silent infections might be expected. Source of the epidemic Although the first case began his symptoms six days after receiving an injection in Yambuku, it is of interest to follow his movements in the threeweek period preceeding his illness. This person had been on a touristic visit to Mobaye-Bongo Zone in the northern part of the Equateur Region from August with six other mission employees travelling in a mission vehicle.

On his return to Yambuku on 22 August, he bought some freshly killed, and some smoked, antelope, and another traveller in the group bought some freshly killed, and some smoked, monkey from a local market along the route.

His wife dried and stewed the antelope upon his return and this was consumed by his entire family. He had no contact with the monkey after his return to the village. The only possible animal contacts at the household were with two ducks.

This person left to work in his nearby banana plantation a few days following his return.The outbreak of the Ebola Hemorrhagic Fever virus is an epidemic and a human catastrophe, taking place in some of the world’s poorest countries.

Ebola hemorrhagic fever (alternatively Ebola Haemorrhagic Fever, EHF, or just Ebola) is a very rare, but severe, mostly fatal infectious disease occurring in humans and other primates, caused by.

Ebola Virus Disease (EVD) is a rare and deadly disease in people and nonhuman primates.

Putting patients at the heart of research

The viruses that cause EVD are located mainly in sub-Saharan Africa. People can get EVD through direct contact with an infected animal (bat or nonhuman primate) or a sick or dead person infected with Ebola virus.
