After the large-scale outbreak of Ebola hemorrhagic fever (EHF) in Bandundu region, Democratic Republic of the Congo, a program was developed to help detect and prevent future outbreaks of EHF in the region. The long-term surveillance and prevention strategy is based on early recognition by physicians, immediate initiation of enhanced barrier-nursing practices, and the use of an immunohistochemical diagnostic test performed on formalin-fixed skin specimens of patients who die of suspected viral hemorrhagic fever. ⋯ Specimen collection kits were distributed to clinics in participating health zones, and a follow-up evaluation was conducted after 6 months. The use of a formalin-fixed skin specimen for laboratory confirmation of EHF can provide an appropriate method for EHF surveillance when linked with physician training, use of viral hemorrhagic fever isolation precautions, and follow-up investigation.

The Ebola epidemic in Kikwit, Democratic Republic of the Congo, was recognized because of a nosocomial outbreak in Kikwit General Hospital. Initially, a diagnosis of shigella infection was suspected because many patients presented with bloody diarrhea. On 4 May 1995, blood samples from 14 acutely ill patients were sent to the Centers for Disease Control and Prevention (Atlanta), and on 9 May, a diagnosis of Ebola hemorrhagic fever was confirmed. The major disease control measures that were undertaken were the isolation of patients in a quarantine ward at Kikwit General Hospital, the distribution of protective equipment to health care workers and family members caring for Ebola patients, the use of barrier nursing techniques, the distribution of health education material, active and passive case finding, and the burying of the deceased in plastic bags by a trained team of Red Cross volunteers who wore gloves and protective clothing.

The outbreak of Ebola hemorrhagic fever in Kikwit, Democratic Republic of the Congo, clearly signaled an end to the days when physicians and researchers could work in relative obscurity on problems of international importance, and it provided many lessons to the international public health and scientific communities. In particular, the outbreak signaled a need for stronger infectious disease surveillance and control worldwide, for improved international preparedness to provide support when similar outbreaks occur, and for accommodating the needs of the press in providing valid information. A need for more broad-based international health regulations and electronic information systems within the World Health Organization also became evident, as did the realization that there are new and more diverse partners able to rapidly respond to international outbreaks. Finally, a need for continued and coordinated Ebola research was identified, especially as concerns development of simple and valid diagnostic tests, better patient management procedures, and identification of the natural reservoir.

On 6 May 1995, the Médecins sans Frontières (MSF) coordinator in Kinshasa, Democratic Republic of the Congo (DRC), received a request for assistance for what was believed to be a concurrent outbreak of bacillary dysentery and viral hemorrhagic fever (suspected Ebola hemorrhagic fever [EHF]) in the town of Kikwit, DRC. On 11 May, the MSF intervention team assessed Kikwit General Hospital. ⋯ The priorities set by MSF were to establish a functional isolation ward to deal with EHF and to distribute protective supplies to individuals who were involved with patient care. Before the intervention, 67 health workers contracted EHF; after the initiation of control measures, just 3 cases were reported among health staff and none among Red Cross volunteers involved in body burial.

Three (15%) of 20 survivors of the 1995 Ebola outbreak in the Democratic Republic of the Congo enrolled in a follow-up study and 1 other survivor developed ocular manifestations after being asymptomatic for 1 month. Patients complained of ocular pain, photophobia, hyperlacrimation, and loss of visual acuity. Ocular examination revealed uveitis in all 4 patients. All patients improved with a topical treatment of 1% atropine and steroids.
