Now documented that Ebola can recur, or else persist (and therefore be transmissible) from survivors.

Only 2 documented cases of recurrence.  Must be v low risk.

Where blood/urine PCR positive, always ill. Detectable in urine, sweat for up to 40 days.

Circulating neutralizing antibody would reduce risk from blood, but “immune protected” sites different eg Eyes, Pregnancy / breast milk, semen, Central nervous system.

Only 2 cases of sexually transmitted ebola.

So far no evidence of persistence beyond 1yr.
