IFNA1 and disease arising from reactivation of latent virus: The addition of 100 U/mL and 1000 U/mL of IFNα led to a decline in latent infection from a mean of 30 to 11 and 3 EGFP+ cells respectively (p = 0.002 and 0.012) and a relative mean (range) inhibition of 62 (58–71) and 87 (74–95)% respectively (p = 0.0003 and p = 0.0004).
