Not since getting back from trips to Bangladesh & Thailand very early January. The Wife got back from China on 27th January. Since then 0. My Lad will be flying back to HKG from UK early in June & will be in self-isolation for 14 days.
If you fly - get used to the inconvenience and given this viruses ability to infect - wear a mask, take your alcohol wipes and avoid eating/drinking (apart from what you can carry on yourself). I'd want an empty seat next to me if possible.
