I was working the Satellite sector.  I had several aircraft in my airspace on two frequencies and constant shout line communication. I was delivering aircraft to the adjacent sector at even altitudes (correct direction of flight).  ZZZ Tower tagged and coordinated a VFR aircraft with an alternator issue as what I deemed could be a possible emergency; but I was not in communication with the aircraft.  A separate target not tagged indicated 4;000 feet. To prevent a possible conflict I climbed the multiple aircraft I was delivering to 6;000.  This altered the altitude we usually deliver aircraft in that sector.  I received a arrival to ZZZ at 5;000; knowing I would have to separate my arrival from the aircraft with the alternator issue not on frequency I started the aircraft decent earlier than usual. I cleared the ZZZ arrival aircraft to ZZZZZ; the initial approach fix. I descended an arrival aircraft to Runway X based on the lateral course ZZZZZ offered.  The aircraft made a very slow course to ZZZZZ.  Realizing the conflict I issued heading to diverge the courses.  Shoutline; multiple frequencies; workload and reduced staffing all played a role in this error.  With reduced staffing during this pandemic; we are working with less of the manpower we are normally afforded.  While commercial traffic is down general aviation has remained solid.  We need to staff based on the demand.
TRACON Controller reported an airborne conflict and attributed it to staffing levels due to the COVID-19 pandemic.
