Article Synopsis
  • The study evaluates the economic costs of providing COVID-19 self-testing in five different countries, aiming to improve access to testing three years into the pandemic.
  • Results showed that the cost per self-test kit ranged from $2.44 to $12.78, influenced by the duration of implementation and demand, with a potential 50% price reduction bringing costs down to between $1.04 and $3.07.
  • Key costs were largely driven by test procurement, accounting for 58-87% of expenses for off-site testing and 15-50% for on-site, with staffing costs being more significant for on-site self-testing.
