I am a Swiss citizen living and working in London. Mid March I made a trip to Switzerland and decided to stay here for the time of the Corona pandemic. During that time I will continue working remotely for an office in London. I have an EHIC and am insured under NHS – my travel insurance plan I purchased only covers travels for up to 2 weeks. Is there a need for any additional insurance coverage or am I sufficiently covered? Additionally – do I have to purchase a Swiss insurance at one point if I am going to stay in Switzerland for several months (even if working/being a resident in London)? Thank you!
