I work tracking covid positives, there is a lot of info going mouth to mouth but i have contacted many many positives.
From my experience, the problem is not your neighbour cuz virus is spread over all places.
Old people that do not go out of house got it, and got hospitalized with severe pneumonia, this people how do they get it? well this are the most fragile people if virus is in food or other surfaces they will get it then virus will develope in their bodies and will propagate to less fragile people.
A lot of peopel get precautions but with friends family and close encounters with partners they do not take precautions, and this people could have virus but not symptoms , you can get it.
There is a time period were people can transmit virus from what i see but i have no science or empirical data just my guess from what i see.
A lot of positives are errors this could be those who do not have symptoms.
People need to work i found people working that are living close to positives ( legally this is forbidden you have to confine for 15 days ), this people work as deliver people, as fastfood worker or as food packing person, so basically you will get a trace of virus everywere.
Hygene is important but also knowledge and this is what is missing in our day to day society , they just say number of cases but we are not experimenting how it works, so people feel is fake or comspiracy.
I have to say every person idea of this virus has a grade of truth so as crazy as it may look a conspiracy theory it has its own grade of truth.
This virus is here to stay and the hardest part is yet to come ( or not if does not mutate in future ).
Flu i a headache but the new flu is a pneumonia some will feel just dizzy and some will never breath again as good as before, guessing which will be ur case is gambling with health , so as people here says, just take care of ur hygene and take precautions.
The rate of severe symptomes is very low but the virus is here and is not any fake new.
