Eligibility

Inclusion Criteria:

• Participant reported a fever with an onset within the last 48 hours

• A woman of childbearing potential must have a negative serum pregnancy test at screening

• A woman must be: a. not of childbearing potential, b. of childbearing potential and practicing a highly effective, preferably user-independent method of contraception (failure rate of less than [<] 1% per year when used consistently and correctly) and agrees to remain on a highly effective method while receiving study intervention and until at least 90 days after last dose- the end of relevant systemic exposure

• A male participant must agree not to donate sperm for the purpose of reproduction during the study and for a minimum of 90 days after receiving the last dose of study intervention

Exclusion Criteria:

• Participant with any clinical signs and symptoms for severe dengue according to the world health organization (WHO) criteria (such as severe plasma leakage leading to dengue shock syndrome [DSS], fluid accumulation with respiratory distress, severe bleeding, sever organ involvement)

• Use of any cytochrome 3A4 (CYP3A4) inducers (example, phenytoin, rifampin), UDP glucuronosyltransferase family 1 member A9 (UGT1A9) inducers (example, rifampin), or substrates for CYP3A4 with a narrow therapeutic range (example, alfentanil, cyclosporin), or sensitive breast cancer resistance protein (BCRP) substrates (example, pravastatin and folic acid) from 14 days before first dose of study drug until 28 days after last dose of study drug. Systemic use of strong CYP3A4 inhibitors (example, clarithromycin, itraconazole) or UGT1A9 inhibitors (example, probenecid, mefenamic acid) from 7 days before first dose of study drug until 28 days after last dose of study drug

• History of malignancy within 5 years before screening (exceptions are squamous and basal cell carcinomas of the skin and carcinoma in situ of the cervix, or malignancy, which is considered cured with minimal risk of recurrence)

• Had major surgery, (example, requiring general anesthesia) within 4 weeks before screening, or will not have fully recovered from surgery, or has surgery planned during the time the participant is expected to participate in the study

• Known or suspected congenital or acquired immunodeficiency; or receipt of immunomodulation therapy such as anti-cancer chemotherapy or radiation therapy; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months)

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Area Under the Log10-Transformed Dengue Virus (DENV) RiboNucleic Acid (RNA) Viral Load (VL) Curve From Baseline Until Day 5 (AUCD1-D5 [log10VL]).	The antiviral activity of JNJ-64281802 versus placebo in terms of reduction of DENV RNA in participants with a primary DENV infection was planned to be measured by the area under the log10-transformed DENV RNA viral load concentration-time curves from baseline (Day 1) until Day 5 (AUCD1-D5 [log10VL]).	Baseline (Day 1) upto Day 5
Secondary	Number of Participants With Treatment-Emergent Adverse Events (TEAEs)	An adverse event (AE) is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. TEAEs were those AE events that occurred at or after the initial administration of study intervention through the last onsite visit.	From Day 1 up to the last onsite visit (Day 30)
Secondary	Number of Participants With Clinically Significant Abnormalities in Electrocardiogram (ECG) Findings	Number of participants with clinically significant abnormalities in ECGs parameters as assessed based on investigator's discretion were reported.	From Day 1 up to the last onsite visit (Day 30)
Secondary	Number of Participants With Clinically Significant Abnormalities in Physical Examination	Number of participants with clinically significant abnormalities in physical examination parameters (head/neck/thyroid, eyes/ears/nose/throat, respiratory, cardiovascular, lymph nodes, abdomen, skin, musculoskeletal, and neurological) as assessed based on investigator's discretion were reported.	From Day 1 up to the last onsite visit (Day 30)
Secondary	Number of Participants With Clinically Significant Abnormalities in Vital Signs	Number of participants with clinically significant abnormalities in vital signs (temperature, pulse/heart rate, respiratory rate, peripheral capillary oxygen saturation [spO2], input-output [I/O] ratio and blood pressure) as assessed based on investigator's discretion were reported.	From Day 1 up to the last onsite visit (Day 30)
Secondary	Number of Participants With Clinically Significant Abnormalities in Laboratory Parameters	Number of participants with clinically significant abnormalities in laboratory parameters (serum chemistry, hematology, and coagulation) were reported. Clinical significance was defined as per investigator's judgement.	From Day 1 up to the last onsite visit (Day 30)
Secondary	Plasma Concentrations of JNJ-64281802	Plasma Concentrations of JNJ-64281802 was assessed. Due to small number of enrolled participants, no summary statistics analysis was performed. Participant wise data were reported for this outcome measure.	Predose: 0, 8, 16 hours on Day 1; 24, 32, 40 hours on Day 2; Day 4, Day 5; and Post dose: 4, 12 hours on Day 1; 28, 36 hours on Day 2; 48 hours on Day 3; Day 6, Day 14, Day 21, Day 28
Secondary	Number of Participants With Occurrence of Detectable Dengue Virus (DENV) RiboNucleic Acid (RNA) in Primary DENV Infection	Number of participants with occurrence of detectable DENV RNA in primary DENV infection was a planned analysis.	Predose: 24 hour on Day 2; Post dose: 12 hour on Day 1; 36 hour on Day 2; Days 3, 4, 5, 6, 7, 8, 9, 14, 21 and 28
Secondary	Time to Undetectable Dengue Virus (DENV) RiboNucleic Acid (RNA) in Primary DENV Infection	Time to undetectable DENV RNA in primary DENV infection was a planned analysis.	Predose: 24 hour on Day 2; Post dose: 12 hour on Day 1; 36 hour on Day 2; Days 3, 4, 5, 6, 7, 8, 9, 14, 21 and 28
