I am in DK where the first phase of relaxing lockdown has not resulted in a second spike in cases. Phase 1 began on the 15th April, opening nurseries/childcare, primary school and special needs schooling of all ages but with new distancing measures, and also businesses with close unavoidable contact can consider opening eg hairdressing, physio, chiropody, dental care, opticians etc but also things like driving schools. No gatherings of over 10 people, PPE and an upscaling of public transport eg longer trains, more frequent buses to deal with the increased demand while allowing social distancing. That's been nearly a month now and there has been no observed surge in cases. Probably because people seem to be taking the rules seriously and there is a lower population density in most places here so its easier to keep to the guidance. Covid is still here, still new cases every day but not huge or exponential numbers. Care homes etc still kept very isolated. Public health services here never completely shut eg chemo and cancer operations etc continued but in the last 2 -3 weeks clinics and elective operations eg hips and knees have been cautiously opening with screening and/or testing for Corona before admission
Phase 2 will start 11th May this will be opening of more shops and bigger shopping centres, outdoor sports as long as gatherings are not more than 50 people. On the 18th comes Secondary schools, libraries, cafes, restaurants, pubs with physical distancing measures in place, churches and drive through safari parks, professional sport without audience. It will be interesting to see how this goes.
Planned for Phase 3 on 8th June are indoor sports, adult education eg evening schools and social clubs, cultural institutions eg art galleries, museums, zoos, planned childrens summer activities, and potentially return to work for those still working from home in both the public and private sector but this is all dependant on phase 2
Phase 4 is back to total opening eg universtities , nightclubs, fitness centres and gatherings of over 500 people and is tentatively planned for August if phases 2 and 3 go well. Borders are shut until 1st June as a minimum and will be considered/negotiated further and of course all this is subject to change/reimposition of full lockdown if there is a sign its going too fast
Not perfect, still a worrying time but it shows that a second spike isn't inevitable depending on how the reopening/easing of lockdown is done. What sounds as though it will result in a spike is a rapid free for all/business as usual opening, or opening before the R numbers are low enough.
