Narrative:

I was vectored for a visual approach to runway X. When asked to contact tower I switched frequencies; but forgot to contact the tower and unfortunately landed without a clearance. During this time I was monitoring my medical crew in the back as we had a very sick passenger on board. This is not an excuse but with all the covid-19 patients we've been flying the last few weeks I've just found myself a bit preoccupied with thoughts of bringing the virus home to my family and not knowing it. That being said; even with everything that is going on; as a professional we still need to pay attention to the task at hand and not get complacent. That truly is why this happened I feel. We get comfortable at our home environment; beautiful day and we forget the simple things that are a vital part of the operation. It's been fairly quiet at the airport except for a few passenger and air ambulance flights; so there was no infraction of airspace or anything that involved another aircraft but is still something that after years of flying I can't believe happened. Bottom line; we have to pay attention!
