Eligible patients will be assigned randomly at a 1:1 ratio.\n\nFor each patient who is included, treatment may last up to 10 days. During the study, subjects will be treated with recombinant human interferon α-2b gel (either before or after the alteration of the active ingredient manufacturer), at a frequency of four times a day, together with a background therapy of valaciclovir hydrochloride.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '70 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Main Inclusion Criteria:\n\n1.
