There are two main limitations in the current study. First and foremost, clinical information on the sampled bats is limited to the brief period of captivity needed for sample collection, which is unlikely to reflect the disease association of the virus accurately. In other words, the scope of the study is limited to surveillance of viral diversity and possible discovery of new viruses. Secondly, the number of samples for the novel virus is quite small, despite the use of specific PCR primers for screening and the relatively large number of samples collected. Thus, we were unable to draw conclusions on the seasonality of its detection or its host specificity. To address these limitations, long-term follow-up studies would be required to identify sufficient positive samples with associated clinical data. Increasing the scale of surveillance would also help, though there are practical geographical and logistic constraints in our locality.
