The article abstract and reference below, details how in patient samples sequenced by the friendly Wuhan Institute of Virology, Nipah virus vector sequences were found. Nipah is a BSL4-level pathogen and CDC-designated Bioterrorism Agent. I wonder when someone cooking bat soup down the road from the Wuhan Institute of Virology will release this virus to our happy globalised world, and enrich us with its bio-diversity? Of course, the bats did it!

“Nipah virus vector sequences in COVID-19 patient samples sequenced by the Wuhan Institute of Virology

Quay, Steven Carl; Zhang, Daoyu; Jones, Adrian;  Deigin, Yuri

We report the detection of Nipah virus in an infectious clone format, a BSL4-level pathogen and CDC-designated Bioterrorism Agent, in raw RNA-Seq sequencing reads deposited by the Wuhan Institute of Virology (WIV) produced from five December 2019 patients infected with SARS-CoV-2. Research involving Nipah infectious clones has never been reported to have occurred at the WIV. These patient samples have been previously reported to contain reads from several other viruses: Influenza A, Spodoptera frugiperda rhabdovirus and Nipah. Previous authors have interpreted the presence of these virus sequences as indicative of co-infections of the patients in question by these pathogens or laboratory contamination. However, our analysis shows that NiV genes are encapsulated in synthetic vectors, which we infer was for assembly of a NiV infectious clone. In particular, we document the finding of internal N, P/V/W/C and L protein coding sequences as well as coverage of the G and F genes. Furthermore, the format of Hepatitis D virus ribozyme and T7 terminator downstream of the 5’ end of the NiV sequence is consistent with truncation required at the end of the genome for a full-length infectious clone. This indicates that research at WIV was being conducted on an assembled NiV infectious clone. Contamination of patient sequencing reads by an infectious NiV clone of the highly pathogenic Bangladesh strain could indicate a significant breach of BSL4 protocols. We call on WIV to explain the purpose of this research on infectious clones of Nipah Virus, the full chronology of
this work, and to explain how and at what stage of sample preparation this contamination occurred.”
