The study will be conducted in two parts, and each Group (A or B) will proceed independently through the study. Part 1 is a dose ranging study with three sequential cohorts of eight patients each that will be randomized 3:1 to receive IV galidesivir or placebo every 12 hours for 7 days. Upon completion of part 1, an optimized dosing regimen of galidesivir will be selected for part 2, based on part 1 results including safety, PK, viral load reduction, and improvement in signs and symptoms and clinical manifestations, and mortality. In part 2, up to 42 patients will be randomized 2:1 to receive IV galidesivir or placebo. After treatment, the patients will remain hospitalized until resolution of symptoms allows release. All patients will be followed for mortality through Day 56.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria: Group A - Yellow Fever\n\n* Ability to provide written informed consent\n* Males and nonpregnant, non-breast-feeding females, aged 18 years or older\n* Subject weight ≥ 50 kg (110 lb.)\n* Positive test for YFV by molecular amplification of the virus in the blood\n* First onset of symptoms of YF occurring within the previous 7 days\n* Male and female subjects must agree to the contraception requirements and must meet the inclusion criteria regarding contraception as outlined in the protocol\n* CLCR of at least 60 mL/min by Cockcroft-Gault equation\n* AST \\< 5000 u/L\n* Indirect bilirubin \\< 1.5 mg/dL\n* Neutrophil count \\< 7500 /mm3\n* International Normalized Ratio (INR) \\< 1.5\n\nExclusion Criteria: Group A - Yellow Fever\n\n* Any clinically significant medical condition or medical history that, in the opinion of the investigator or sponsor, would interfere with the subject's ability to participate in the study or increase the risk of participation for that subject\n* Employment by the study site, or an immediate family relationship to either study site employees or Sponsor employee\n* Lack of suitable veins for venipuncture/cannulation as assessed by the Investigator at Screening\n* Participation in any other investigational drug or vaccine study currently or within the past 30 days\n* Diagnosis of YF vaccine-related viscerotropic disease\n* Subjects with hepatic encephalopathy as defined by Conn Score ≥ 1.\n* Subject has severe immunosuppression or immunodeficiency, leukemia, lymphoma, thymic disease, generalized malignancy, or radiation therapy (within the past 3 months), or is undergoing current treatment with immunosuppressive drugs, defined as drugs that impair immune responses to infections\n* A treatment plan for YF that would include concomitant administration of antiviral medications\n\nInclusion Criteria Group B - COVID-19\n\n* Ability to provide written informed consent, accept randomization to any assigned treatment arm, and comply with planned study procedures\n* Males and nonpregnant, non-breast-feeding females, aged 18 years or older\n* Male and female subjects must agree to the contraception requirements and must meet the inclusion criteria regarding contraception as outlined in the protocol\n* Subject weight ≥ 50 kg (110 lb.)\n* Clinical syndrome consistent with moderate-severe (but not critically ill) COVID-19, defined by at least one of the following:\n\n 1.
