After 6 months, a deadly outbreak of Marburg hemorrhagic fever in Angola
that began in October 2004 appeared to be on the wane. By late April, reported
World Health Organization (WHO) officials, the average number of cases had
declined from about 35 per week to 15 per week.
According to Angola’s Ministry of Health, 266 cases of the rare
disease had been identified as of April 20, 244 of them fatal—the largest
and deadliest Marburg outbreak on record, with a case-fatality rate greater
than 90%. Controlling the problem had been hindered by affected populations’
extreme anxiety about the disease and suspicions about the safety of hospitals,
leading communities to hide cases and bodies.
