There will need to be more regulations on public health safety in the workplace and gathering places. Anyone working around other people or with clients will need to be regularly tested and cleared to work around others. Businesses can work with public health agencies to cover the costs and procedures for testing.
There needs to be a direct line of regulation because there is a flood of regulations from Federal, State, region, county or city level that all require different measures and can confuse the public rather than help. Also, professional business organizations also have their own regulations, so there needs to be a consensus of public and private authorities on what groups need which measures for health and safety of workers and clients.
