During the spring and summer of 2001, an outbreak of eight cases of Crimean-Congo hemorrhagic fever (CCHF) occurred in Albania. The epidemiological investigation, the clinical presentation of the cases, and the course of the disease are described. Seven of the cases were laboratory confirmed. A nosocomial infection and a cluster of cases within a family were observed. Genetic analysis of the CCHF virus strain that caused the outbreak showed that it was clustered together with other European CCHF virus strains except the Greek one (strain AP92). The Greek strain, which forms an independent clade, differed from the causative strain by 25.3% at the nucleotide level.
