Hon JENNY SALESA: What I can say is that from the very beginning, we've had public health officials actually walk through and ensure that our customs staff know how to actually wear personal protective equipment (PPE). Customs maintains physical distancing, and the use of masks and gloves is something that customs do. As I say, the result speaks for itself. None of the customs staff have been tested as COVID-19 - positive; they have been tested, though. There's also been high participation of customs officers for volunteering for testing. One of the things that customs has done is it's redeployed a lot of its staff to ensure that they also help out with contact tracing. As I say, the result of customs not having had any COVID-19 cases is one thing that we can look to in terms of their adherence with PPE and with health and safety measures.
