It is reported to be up to 60% more transmissible. I'm OK, and I'm not taking any precautions, as I haven't been vaccinated, so I still have all my natural immunity.
I hope you don't have any older family members around you that you could infect. My biggest fear is that I get the virus, don't have symptoms and then infect my 90 year old grandmother. I got the first shot of vaccination in May, but it seems that one dose is not enough to protect us from the delta variant. I will be more cautious until I get the second injection in 4 weeks.
