Acute Hepatitis C Outbreak among HIV-infected Men, Madrid, Spain

shown to be naturally infected with Zaire Ebolavirus and Marburg virus. Thus, R. amplexicaudatus bats are a possible natural reservoir of REBOV. However, only 16 specimens of R. amplexicaudatus bats were available in this study, and it will be necessary to investigate more specimens of this species to detect the REBOV genome or antigens to conclude the bat is a natural reservoir for REBOV. We have shown that R. amplexicaudatus bats are putatively infected with REBOV or closely related viruses in the Philippines. Antibodypositive bats were captured at the sites near the study areas, where REBOV infections in cynomolgus monkeys and swine have been identifi ed. Thus, bats are a possible natural reservoir of REBOV. Further analysis to demonstrate the REBOV genome in bats is necessary to conclude that the bat is a reservoir of REBOV.
