Although I’ve covered this issue before, it’s well to bring up the issue of conservatorship and guardianship for elderly seniors living alone, especially if they have no relatives and own condos.
There are ways we can imagine that this can become more critical during the pandemic.
In Virginia, any adult can petition a court to take over an elder’s affairs and move the person to a safer location. Presumably this could include a condominium board, after going through its own due process.
Generally, in the past two or three months, the concerns over surface hygiene and exposure to elevators in a building have not turned out to be critical issues. As long as elders wear face coverings properly and others do so in a building and as long as larger gatherings indoors are avoided, the risk gets much less.
There has, however, been some attention to the idea that a European mutation (in effect since March) makes the virus more transmissible (but not more virulent) than the original Wuhan version.
There can be concerns also if a building has ventilation issues.
There is some new information on face coverings, maintaining that three-layer medical coverings (given out by dentists particularly) are more effective, limiting spread of droplets to only a few inches, whereas a bandana limits distance of droplets to less than 4 feet.
Here is the basic link again on how conservatorship and guardianship work.
