Households face increased healthcare costs, insurance premiums, and potential income loss from reduced work capacity. Long Covid patients may require ongoing cardiac monitoring, medications, and lifestyle modifications, straining household budgets and reducing economic participation.
Governments may need to expand healthcare funding for Long Covid treatment and cardiac care, establish disability support programs, mandate workplace accommodations, and increase research funding. Insurance regulators may require coverage expansions. Occupational health policies will require revision to address Long Covid workplace impacts.
