SARS-CoV-2 and Herpesvirus Inhibition for Ending Long COVID Dysfunction

The EQ VAS records the patient's self-rated health on a visual analogue scale where the endpoints are labelled 'The best health you can imagine' (100) and 'The worst health you can imagine' (0), with higher scores indicating better health state. The VAS can be used as a quantitative measure of health outcome that reflects the patient's own judgement.

The EQ-5D-5L is a validated, standardized, generic instrument that is a preference-based health- related quality of life questionnaire. The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate their health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state. Full scale from 5 to 25, with higher score indicating poorer health outcomes.

The PROMIS-29 v2.0 profile assesses pain intensity using a single 0-10 numeric rating item and seven health domains (physical function, fatigue, pain interference, depressive symptoms, anxiety, ability to participate in social roles and activities, and sleep disturbance) using four items per domain. The values of all item responses are averaged to generate subscores for each dimension. From these subscores, a global physical health score and a global mental health score are generated. The scores are translated into T-scores according to a reference population with a mean of 50 and a standard deviation of 10.

The General Symptom Questionnaire-30 (GSQ-30) is a valid and reliable instrument to assess symptom burden among patients with acute and post-treatment. The GSQ-30 total score ranges from 0 to 120, with higher scores indicating a greater symptom burden.

The PHQ-9 is a series of questions assessing presence and severity of depression symptoms. It evaluates each of the DSM-IV depression criteria and scores the responses from 0 ("Not at all") to 3 ("Nearly every day"). PHQ-9 scores of 5, 10, 15, and 20 represented mild, moderate, moderately severe, and severe depression, respectively. Full scale from 0-27, with higher score indicating more severe symptoms.

The GAD-7 is a 7-item scale developed and validated to identify generalized anxiety disorder and its severity. It assesses the frequency of 7 anxiety symptoms and scores the responses from 0 ("Not at all") to 3 ("Nearly every day"). Total scores of 5, 10, and 15 correspond to mild, moderate, and severe generalized anxiety disorder, respectively. Full scale from 0-21, with higher score indicating more symptoms.

A suicide risk assessment tool that supports suicide risk assessment through a series of simple, plain-language questions that anyone can ask. The answers help users identify whether someone is at risk for suicide, assess the severity and immediacy of that risk, and gauge the level of support that the person needs.

Full range from 0 (low intensity suicidal ideation to 9 (high intensity suicidal ideation). Higher score represents poorer health outcomes.

The Neuro-QoL Cognitive Function v2.0 short form assesses perceived difficulties in cognitive abilities, including memory, attention, decision making, planning, organizing, calculating, remembering, and learning. The short form consists of 8 questions assessed on a 5-point Likert scale, resulting in a raw score range of 8 to 40. A raw score is then converted to a T-score using conversion tables. Scores 0.5 - 1.0 SD worse than the mean (T-score 40-45) = mild symptoms/impairment. Scores 1.0 - 2.0 SD worse than the mean (T-score 30-40) = moderate symptoms/impairment. Scores 2.0 SD or more worse than the mean (T-score below 30) = severe symptoms/impairment.

The SQS is a visual analog scale that instructs respondents to rate their overall quality of sleep over a 7-day recall period from 0 to 10. Scores of 0, 1, 4, 7, and 10 correspond to terrible, poor, fair, good, and excellent, respectively. Higher scores indicate better sleep quality.
