The present study conducted a longitudinal serological survey and active surveillance for influenza virus in freeranging nonhuman primates (NHPs) in Thailand. One hundred and nine serum samples from NHPs were collected
between 2009 and 2017, in 4 provinces of Thailand; while 282 oropharyngeal swabs were collected between April to
August, 2018, in 8 provinces of Thailand. Our results demonstrated that no antibody to influenza virus was found in
NHP sera by using blocking enzyme-linked immunosorbent (ELISA) assay and hemagglutination inhibition (HI) assay.
Moreover, no influenza genome could be detected in all new NHP swab samples by using real-time RT-PCR assay.
However, monitoring and surveying of influenza virus in these species should be maintained.
