Recently, the discovery of “Langya virus” in Shandong and Henan provinces of China has quickly attracted the attention of medical experts around the world. The virus is a type of zoonotic henipavirus and 35 people have been identified to be infected with this Langya virus since 2019 in these two provinces in China.
Notably, this virus is related to the Mojiang virus—found in the infamous Mojian Caves where the bat-borne coronavirus most similar to the SARS-CoV-2 was discovered.
The Wuhan Institute of Virology has become very interested in henipaviruses as of late, taking great pains to obtain and reconstruct the Nipah virus, which is not even a threat in China.
What Is the ‘Langya Virus’? What Are Its Symptoms?
Langya virus is part of the henipavirus family. Other henipaviruses include the Nipah virus, which has received extensive attention and is known for its high mortality rate, and the Hendra virus and Mojiang virus.Henipavirus is a genus of negative-stranded RNA viruses with a lipid membrane on their surface. This membrane is easily damaged in a dry environment, so henipaviruses are not primarily transmitted through the respiratory tract, but through direct contact with infected people or animals or contact with their feces.
All 26 patients with the Langya virus infection have experienced fever. Their probability of suffering from anorexia, coughing, weakness, muscle pain and leukopenia are as large as 50 percent. In addition, liver function impairment, thrombocytopenia, and headaches are also common symptoms of the Langya viral infection.
Mojiang Virus: Henipavirus From a Mysterious Mine in Yunnan, China
The Mojiang virus was found in an infamous abandoned mine in Mojiang County, Yunnan province, China.This mine in Yunnan first attracted attention in 2012, when six miners working inside it contracted severe pneumonia of unknown origin, and three of them died.
This mine resembles a “cave of viruses,” harboring these two dangerous viruses in different hosts: coronaviruses in bats, and Mojiang virus in rodents. There are still many questions remain unanswered about this mysterious cave: what happened to the other three miners who had unknown pneumonia but did not die? Did they have any other coinfections with other viruses? After Mojiang virus was identified, did those miners’ samples get retested for any potential zoonotic infection from Mojiang virus? What is unique in this cave that makes it like a hub of emerging pathogens?
In addition to the discovery of the coronavirus and Mojiang virus, the Chinese military and the Wuhan Institute of Virology (WIV) seem to be very interested in another henipavirus–the Nipah virus. Is WIV working on Nipah virus as a biological weapon candidate?
Recently, a renowned scientist pointed out that WIV might still be conducting genetic research on the Nipah virus.
Dr. Quay had discovered that the original raw data of the SARS-CoV-2 virus study contained part of the genome sequences of the Nipah virus, and somegene sequences were relatively complete. In addition, it also contains part of the vector sequences that are used for synthetic biology. Therefore, Dr. Quay suspected that WIV might be working on the restructuring or engineering of an infectious clone of Nipah virus strain, which is a highly lethal and very dangerous virus.
This was not just a speculation as WIV’s strong interest in Nipah virus was found in another very unusual incident:
China does not currently face the threat of the Nipah virus, and there is no urgent need to develop a vaccine for it. So why is WIV so interested in the Nipah virus? This is an alarming question.
Before the outbreak of COVID-19, the website of WIV even listed a “military management division.” This suggested that WIV is not just merely a collaborator for the People’s Liberation Army. Military operation was part of the whole WIV operation even before Xi Jinping launched nation-wide Military-Civil fusion transformation for many institutes.
A Military Field-Testing of Dangerous Pathogens?
Indeed, the discovery of the Langya virus also showed elements of military involvement.The key authors to that report are Drs. Li-Qun Fang and Wei Liu, whose institutional affiliation was shown to be “Beijing Institute of Microbiology and Epidemiology (BIME)”. However, BIME is actually the same entity as “Institute of Microbiology and Epidemiology, Academy of Military Medical Sciences, under People’s Liberation Army.” In addition, in the supplementary materials of this report, it was clearly indicated that the PLA’s 990 Military Hospital in Henan province was involved in this study. And the report indicated that 34 out of the 35 patients were local farmers. Why were the farmers’ samples analyzed in a military hospital as part of a sentinel surveillance program?
Moreover, although the report indicated that those 35 patients infected with Langya virus were identified during “sentinel febrile illness surveillance.” It is very unusual to report the discovery and isolation of a live henipavirus with significant delay of two years. The discovery of henipavirus should be very alarming news in the public health aspect, and should have been reported in 2019. Meanwhile, among the 35 patients, six patients were found to be co-infected with severe fever with thrombocytopenia syndrome virus (SFTSV) , and two patients were found to be co-infected with Hantavirus.
The SFTSV and Hantavirus are highly infectious viruses that could lead to severe viral hemorrhage and their outbreaks in China are relatively rare events. So, in this so-called “sentinel febrile illness surveillance”, this group of military scientists identified three dangerious pathogens at one time, and several of them were co-infected with two rare pathogens? How likely would this happen in a natural situation? And in regular sentinel febrile illness surveillance, these viruses would not be included in the regular screening under normal circumstances.
Such Virus Research Endangers the Health of Mankind and Needs to Be Called Off
Following the COVID-19 outbreak, there has been a growing concern about the risks associated with research into viruses.As aforementioned, the scientists and journalists attempting to enter the Mojiang mine to investigate are now being blocked on the grounds of “political sensitivity.” However, if this series of events directly endangers the health of all humans, then this should not be considered a mere political issue.
At this stage, various viruses, bacteria, and other public health crises are already posing a great threat to people. On this basis, some organizations are still conducting daring research, such as modifying human genes and/or viral genes, and using various synthetic biology means to assemble new viruses and bacteria.
These dangerous studies have been glorified as a way to better understand pathogens and develop vaccines and drugs.
However, during the process, people may have created more dangerous pathogens that further threaten the health of the human race. An outbreak of a dangerous pathogen, whether from natural zoonotic infection, or laboratory leak incident, or a release of biological weapon, can become a major global disaster, as the COVID-19 pandemic has demonstrated.
Therefore, we need to be more stringent in monitoring, controlling, or prohibiting such dangerous research.
In the process of promoting the development of biotechnology, we must first guard the most basic medical ethics and the ethics of researchers.
