I saw this post: https://medium.com/@indica/how-korea-is-reopening-24ce3e9a1d69
regarding what South Korea's health government has stressed for distancing in daily life.

South Korea's Guideline pdf: https://covidtranslate.org/more-resources/routine-distancing-guidelines/

I know US is not like South Korea, but some of the guidelines can help us to keep safe from coronavirus.

Here's how they do contact tracing: https://medium.com/@indica/how-korea-does-contact-tracing-1b2662b5b894

I've been looking for what can be done indoors with HVAC systems and CDC & EPA are recommending:


"The evidence suggests that mitigating airborne transmission should be at the front of our disease-control strategies for covid-19. In some ways, that only bolsters public health measures already in place, such as avoiding groups and wearing masks in public. But it also requires that we minimize exposure to airborne pathogens, especially indoors.
To do that, we need to do two things. First, maintain physical distancing. Six feet is good, but 10 feet is better. Second, we must deploy healthy building strategies, such as refreshing stale indoor air. We do this by opening windows in our homes and cars and by increasing the outdoor air ventilation rate in buildings with HVAC systems. Any recirculated air needs to pass through a high-efficiency filter so an infected person in one room doesnít contaminate people in an adjacent room (as happened with the first SARS outbreak). We also have to make sure places such as bathrooms and rooms with infected patients have enough exhaust, and are negatively pressurized relative to common areas, so any airborne virus is confined to limited areas. This isnít rocket science; as far back as 1860, Florence Nightingale said, "Cleanliness and fresh air from open windows, with unremitting attention to the patient are the only defence a true nurse either asks or needs."

CDC: https://www.cdc.gov/coronavirus/2019-ncov/community/office-buildings.html

"Before resuming business operations, check the building to see if itís ready for occupancy.
Ensure that ventilation systems in your facility operate properly. For building heating, ventilation, and air conditioning (HVAC systems) that have been shut down or on setback, review new construction start-up guidance provided in ASHRAE Standard 180-2018, Standard Practice for the Inspection and Maintenance of Commercial Building HVAC Systems.
Increase circulation of outdoor air as much as possible by opening windows and doors, using fans, and other methods. Do not open windows and doors if doing so poses a safety or health risk for current or subsequent occupants, including children (e.g., allowing outdoor environmental contaminants including carbon monoxide, molds, or pollens into the building).
Evaluate the building and its mechanical and life safety systems to determine if the building is ready for occupancy. Check for hazards associated with prolonged facility shutdown such as mold growth, rodents or pests, or issues with stagnant water systems, and take appropriate remedial actions."

Most of the superspreader coronavirus cases were indoors.
