Study Endpoints
Primary Endpoints
Respiratory Syncytial Virus (RSV) Viral Load-time Curve From Immediately Prior to First Dose of JNJ-53718678 Through Day 5 (AUC [Day 1-5])
Baseline (Day 1) up to Day 5

RSV viral load AUC was determined from immediately prior to first dose of JNJ-53718678 through Day 5. The RSV viral load was measured by quantitative reverse transcription polymerase chain reaction (qRT-PCR) assay in mid-turbinate nasal swab specimens.

Secondary Endpoints
RSV Viral Load Over Time
Baseline, Days 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, and 21
Change From Baseline in RSV Viral Load Over Time

ArmTypeDescription
Part 1-Observational PhaseOTHERParticipants will not receive any intervention in the observation phase. All infants will be closely monitored for early signs and symptoms of Respiratory Syncytial Virus (RSV) disease using a mobile RSV application on the parent/caregiver's mobile phone, upon an alert, the RSV will be tested, if RSV negative participants (RSV \[-\] diagnosed at site) will return to the pre-diagnostic phase and RSV positive participants (RSV \[+\] diagnosed at site) can be enrolled in the interventional stage of the study after obtaining informed consent for the interventional stage at that time. RSV (+) participants whose parent(s)/caregiver(s) do not consent for enrollment in the interventional stage and participants who are screening failures in the interventional stage will enter the post-diagnostic phase of the observational stage (hospitalized or outpatients).
Part 2-Interventional PhaseEXPERIMENTALParticipants will be randomized to receive either JNJ-53718678 (for Age Group 1 (greater than or equal to \[\>=\] 28 days and less than \[\<\] 3 months): 2.5 milligram per kilogram \[mg/kg\]; for Age Group 2 (\>=3 and \<6 months): 3 mg/kg and for Age Group 3 (\>=6 months): 4.5 mg/kg) or placebo (Age Group 1, 2 and 3) twice daily for 7 days.
Interventions
NameTypeDescription
RSV Mobile ApplicationOTHERParticipants will not receive any intervention in observational phase of this study. Participant's respiratory symptoms will be captured by RSV mobile application installed in participant's caregiver/parent mobile phone.
PlaceboDRUGParticipants in each Age Group (1,2,3) will receive matching placebo (volume placebo to match the calculated volume of the JNJ-53718678 dose) orally twice daily for 7 days.
JNJ-53718678 2.5 mg/kgDRUGJNJ-53718678 will be administered to Age Group 1 twice daily for 7 days.
JNJ-53718678 3 mg/kgDRUGJNJ-53718678 will be administered to Age Group 2 twice daily for 7 days.
JNJ-53718678 4.5 mg/kgDRUGJNJ-53718678 will be administered to Age Group 3 twice daily for 7 days.
