Participant Flow

Inclusion timeframe for the study was initially planned for 6 months. Due to the low rate of inclusion, this timeframe was extended from 6 to 13.5 months. A total of 106 subjects from the Herpes Zoster (HZ) cohort were included in this study.

Out of 106 subjects included,5 subjects were excluded due to the following reasons:\<50 years,previous history of HZ ,not the first visit,consulted physician more than 2 weeks after start of HZ symptoms. A total of 101 subjects were included for analysis.Out of the 101 subjects,90 subjects completed the study.

Timeframe: At Inclusion (Month 0)

Population: The analysis was performed on the subjects who were diagnosed with HZ, complied with inclusion criteria and on subjects belonging to a sub-cohort (PHN cohort) from HZ cohort, diagnosed with PHN at 3 months and followed up for 6 more months.

Evaluation of HZ and PHN related indirect costs, estimated by direct medical costs were done by the sick leave prescription and medical visit at inclusion. Sick leave prescriptions were defined as an indirect medical cost and medical visits were defined as a direct medical cost.

SECONDARY outcome

Timeframe: At inclusion (Month 0), Month 1 and Month 3

Population: The analysis was performed on the subjects who were diagnosed with HZ, complied with inclusion criteria and on subjects belonging to a sub-cohort (PHN cohort) from HZ cohort, diagnosed with PHN at 3 months and followed up for 6 more months.

HZ and PHN severity was evaluated using 3 categories- mild pain (0\<pain\<3), moderate pain (3 ≤ pain \< 7) and severe pain (7 ≤ pain) for the last 24 hour worst pain. The Zoster Brief Pain Inventory (ZBPI) questionnaire is a self-administered form to assess HZ pain and burden associated with HZ pain using scales from: * 0 for no pain to 10 for the most horrible pain that can be imagined, * 0 for no improvement to 100% for full improvement with painkiller, * 0 for no burden to 10 for full burden.

SECONDARY outcome

Timeframe: At inclusion (Month 0)

Population: The analysis was performed on the subjects who were diagnosed with HZ, complied with inclusion criteria and on subjects belonging to a sub-cohort (PHN cohort) from HZ cohort, diagnosed with PHN at 3 months and followed up for 6 more months.

Impact of HZ \& PHN on QOL was evaluated using EQ-5D-5L questionnaire,which has 2 parts: EQ-5D-5L descriptive system \& EQ Visual analogue scale(EQ-VAS). EQ-5D-5L descriptive system comprises of 5 dimensions-mobility,self-care,usual activities,pain/discomfort \& anxiety/depression.Each dimension has 5 levels:not at all(level 1),mild(level 2),moderate(level 3),severe(level 4),extreme/leading to incapacity(level 5),with highest level corresponding to worst outcome.Subjects had to indicate their health state by choosing the appropriate level from each dimension.The 5 digit health states thus obtained for each dimension were then converted into a single mean index value using the EQ-5D-5L crosswalk index value calculator as recommended by EuroQol group.In the EQ-VAS,subjects had to record their health state on a scale ranging from 0(worst imaginable health state) to 100(best imaginable health state).A mean of this health state was recorded for subjects analyzed in this outcome measure
