It's a difficult one this, I'm assuming your courts are open weather and not inside? There is a push to start opening facilities slowly to encourage a normal way of life again albeit a little more safely. However, I would err on the side of caution and continue to monitor the situation over the coming weeks. Whilst single matches might seem harmless it's whether family and friends come to watch and whether or not in then encourages doubles.
Right now it would seem to soon to open up the facility in my opinion. :-)
