The Near and Mid-infrared photometric properties of known redshift
  $z\geq5$ Quasars
  We assemble a catalogue of 488 spectroscopically confirmed very high
($z\geq5.00$) redshift quasars and report their near- ($ZYJHK_{s}/K$) and mid-
(WISE W1234) infrared properties. 97\% of the VH$z$Q sample is detected in one
or more NIR ($ZYJHK/K_{s}$) band, with lack of coverage rather than lack of
depth being the reason for the non-detections. 389 (80\%) of the very high
redshift quasars are detected at 3.4$\mu$m in the W1 band from the unWISE
catalog and all of the $z\geq7$ quasars are detected in both unWISE W1 and W2.
Using archival WFCAM/UKIRT and VIRCAM/VISTA data we check for photometric
variability that might be expected from super-Eddington accretion. We find 28
of the quasars have sufficient NIR measurements and signal-to-noise ratio to
look for variability. Weak variability was detected in multiple bands of SDSS
J0959+0227, and very marginally in the $Y$-band of MMT J0215-0529. Only one
quasar, SDSS J0349+0034, shows significant differences between WFCAM and VISTA
magnitudes in one band. With supermassive black hole accretion likely to be
redshift invariant up to very high-redshift, further monitoring of these
sources is warranted. All the data, analysis codes and plots used and generated
