Can test-to-treat be applied to COVID-19 patients without advanced age or other risk factors?

  • Most of the available evidence comes from studies in populations with risk factors for progression to severe disease, including advanced age. In this population, the benefit is clear.
  • There is less data on the use of Paxlovid (nirmatrelvir/ritonavir) in patients without risk factors (including age). Healthier patients may have less benefit, as their risk of severe disease is lower to begin with.
  • For now, the risk-benefit ratio is only well established in those with risk factors including advanced age.
