    This CDC chart shows that the post-quarantine transmission risk is reduced to 10% after 7 days, and falls away to nearly zero after 14 days. The new CDC recommendation of 10 days balances the 1% risk that remains against the view that the shorter the quarantine requirement, the higher the compliance.
    It also indicates that after 5 days a negative test begins to become an indicator of lower risk of transmission from someone returning to work. (The flip-side of this is that sometimes people who are safe to return to work because it is 10 to 14 days after their last symptoms might still test positive even though they are no longer a high transmission risk.)
