*Dpi, days postinfection; NW, nasal wash; –, Nipah virus not detected by reverse transcription PCR (RT-PCR) for N gene; therefore, virus isolation was not attempted for this sample; empty cells represent days on which sampling was not scheduled for that animal; Indet, mean cycle threshold value >39.1 (the defined cutoff value for positive samples); +/−, virus detected by RT-PCR but negative by virus isolation; +/+, sample positive by RT-PCR and virus isolation; OS, oral sample; RS, rectal sample; NS, not sampled.
†RNA detection by RT-PCR.
‡Pyrexia first detected.
§Virus isolation not attempted for this sample.
