Ebola Virus Infection Associated with Transmission from Survivors
Table 3
Strength of evidence and criteria for sexual transmission of Ebola virus*
Strength of evidence | Criteria |
---|---|
Strong, A + B + C | A.Epidemiologic investigation identified sexual contact between recipient or index person and single proposed/probable source |
AND | |
B.EBOV detected in single proposed/probable source’s semen or vaginal secretions (by a vaginal swab) by RT-PCR | |
AND | |
C.Sequencing indicates high likelihood of transmission to recipient |
|
Moderate, A + B or A + C | A.Epidemiologic investigation identified sexual contact between recipient or index person and single proposed/probable source |
AND | |
B.EBOV detected in single proposed/probable source’s semen or vaginal secretions (by a vaginal swab) by RT-PCR | |
OR | |
C.Sequencing indicates high likelihood of transmission to recipient |
|
Weak |
Epidemiologic investigation identified sexual contact between recipient or index person and single proposed/probable source† |
None | No report of sexual contact |
*EBOV, Ebola virus; RT-PCR, reverse transcription PCR.
†If not countered by sequencing data suggesting that the sexual contact is unlikely to be the source.
