 The CDC estimated that as much as 40 % of the workforce might be unable to work at the peak of the pandemic due to the need for many healthy adults to stay home and care for an ill family member , and advised that individuals should have steps in place should a workplace close down or a situation arise that requires working from home . The CDC further advised that persons in the workplace should stay home sick for seven days after getting the flu , or 24 hours after symptoms end , whichever is longer .
