Although Joe Haldeman’s fever went down overnight with the help of a cooling mattress, Gay Haldeman reports that his doctor wanted him running a fever to help fight infection. So they let his fever run extremely high for awhile, then the doctor put him back on the cold mattress. In her September 27 post to SFF.net Gay says other signs are still okay.
Gay is also posting what are doubtless the same entries to Friends of Joe Haldeman on Facebook, incidentally.
