Subclinical infections with Crimean-Congo hemorrhagic fever virus, Turkey

Emerg Infect Dis. 2012 Apr;18(4):640-2. doi: 10.3201/eid1804.111374.

Abstract

To investigate Crimean-Congo hemorrhagic fever virus in Turkey, we conducted a seroepidemiologic survey during January-April 2009. Seroprevalence of infection was 10% in a sample from an outbreak region and increased with patient age, indicating that the virus had been previously present in Turkey. We also estimated that 88% of infections were subclinical.
