Information for bat workers

The information on this page is targeted at visitors to underground hibernation sites.

Bat workers visiting underground hibernation sites are being asked to:

  • remain vigilant for the symptoms commonly associated with WNS as part of their usual survey activities;
  • report to BCT/the Animal & Plant Health Agency immediately if any symptoms associated with WNS are observed/suspected;
  • follow decontamination procedures after site visits; and
  • anyone visiting sites within the region of a suspect case should carry out the decontamination procedures between site visits. For the latest information about sites see the table below, 'Cases currently under investigation'. 

The guidelines for bat workers and bat carers were updated in light of the first discovery of the fungus in the UK back in 2013 and are updated annually (including for the 2017/18 winter season).  

Cases currently under investigation are those where one or more of the symptoms of WNS have been observed or are suspected. All cases investigated during from the winter survey seasons of 2009 to 2012 came back as negative. During the 2012/13 winter survey period one case was positive for P. destructans and a further case was found during the 2013/14 season, none were found during the 2015/16 or 2016/17 hibernation seasons through passive surveillance but additional cases were found through an active surveillance project. Over the course of the 2017/18 season any new cases will be listed below (including whether we have any results or if the results are outstanding).

Cases currently under investigation

Please note that it may six weeks or longer to report results.

When the status of a case is identified as 'NEGATIVE' that means no P. destructans conidia were isolated during testing.
