Ebola Picture No. 4
This picture shows a transmission electron micrograph of the Ebola virus.
Transmission occurs through direct contact with an infected person or their body fluids (such as blood or secretions). Spread of the virus occurs most often during the late stages of infection.

This picture shows a healthcare worker's materials used in the treatment of Ebola patients at a Yambuku hospital in 1976.
Ebola Picture No. 6
This picture shows bedridden patients in a Sudanese hospital during the country's 1976 outbreak. In 1976, Dr. Joe McCormick and Dr. Roy Baron, along with a number of other investigators, were sent to Nzara to investigate the region's Ebola outbreak.
Early cases of Ebola hemorrhagic fever showed that the virus began in the Nzara Cotton Manufacturing Factory. From there, the disease spread through the town of Nzara, and then went east to the town of Maridi. The virus infected 284 people in Sudan, with 117 deaths.
Once an outbreak begins, the effects of the virus can be devastating. There is no Ebola cure -- in cases of infection, death rates can be as high as 90 percent.
Because there is currently no Ebola vaccine, prevention efforts focus on preventing direct contact with body fluid of those infected and with any persons who have died as a result of the infection.
One method of preventing transmission of Ebola in a hospital setting is through the use of barrier techniques. These include:
- Using infection-control measures, including complete sterilization of equipment
- Isolating people with Ebola from unprotected people
- Wearing protective clothing, such as:

This 1976 picture shows Del Conn, a man who was suspected of having Ebola, while he was lying down within an isolation unit in the Johannesburg Fever Hospital. Here you see Dr. Ruben Sher dressed in protective garments while he was tending to the ill patient.
