The new deadly virus discovered in China is causing alarm among health experts worldwide. Known as the Wetland virus (WELV), this pathogen has been found to have potentially severe effects on the brain.
The virus, first identified in a hospital patient in Jinzhou in June 2019, marks a significant development in the study of tick-borne diseases and their neurological implications.
Understanding the Wetland Virus
The virus discovered in China, Wetland virus (WELV), has emerged as a new and concerning tick-borne pathogen. The initial case involved a 61-year-old man who fell ill after visiting a park in Inner Mongolia, an area known for its large wetland regions.
The patient’s symptoms included fever, headache, and vomiting, which began about five days after he was bitten by ticks in the park. Traditional antibiotic treatments failed to alleviate his condition, suggesting that the infection was viral rather than bacterial.
When doctors examined the patient’s blood samples, they were taken aback by the presence of an unknown orthonairovirus. This family of viruses includes several tick-borne pathogens known to cause severe illnesses such as Crimean-Congo hemorrhagic fever.

The discovery of WELV, which had not been previously seen in humans or animals, prompted further investigation into its potential impact on health.
The Spread of WELV
The investigation into the virus discovered in China led researchers to conduct extensive field studies to understand its spread and potential reservoirs. Over 14,600 ticks were collected and analyzed from various locations and species in northern China, including the park where the patient had been bitten. The results were concerning—approximately 2 percent of these tick samples tested positive for WELV genetic material.
In addition to ticks, WELV was also found in a small percentage of livestock, including sheep, horses, and pigs, as well as in rodents known as Transbaikal zokor (Myospalax psilurus). The detection of WELV in these animals suggests that the virus has a broader ecological presence, which may contribute to its transmission to humans.
Impact on Human Health
The presence of the virus discovered in China has significant implications for human health. Blood samples from forest rangers in the region revealed antibodies to WELV in 12 out of 640 individuals. This finding indicates that the virus has been circulating in the area, potentially affecting more people than initially recognized.
Patients with confirmed WELV infections exhibited a range of symptoms, from mild fever and dizziness to severe neurological issues such as nausea, diarrhea, and, in extreme cases, coma. One patient fell into a coma due to high white blood cell counts in the brain and spinal fluid, highlighting the virus’s potential to cause severe brain damage.

Laboratory experiments on mice further revealed that WELV could cause lethal infections and impact the nervous system. These findings underscore the virus’s potential to cause severe health issues, particularly those involving the brain, and emphasize the need for continued research and monitoring.
Virus Discovered in China
The discovery of WELV presents both challenges and opportunities for the global health community. The potential for severe neurological damage caused by this new virus highlights the importance of ongoing research to understand its transmission, effects, and potential treatments. Health authorities and researchers are working together to monitor the virus’s spread and develop strategies to mitigate its impact.
Public health measures, such as tick control and awareness campaigns, are crucial in preventing further infections. Additionally, continued surveillance of animal reservoirs and tick populations will be essential in tracking the virus’s spread and assessing its potential threat to human health.
The new deadly virus discovered in China, known as Wetland virus (WELV), has raised significant concerns due to its potential to affect the brain. The virus, first identified in a hospital patient in Jinzhou, has been found in ticks, livestock, and rodents, indicating a broader ecological presence.
With its ability to cause severe neurological symptoms and potentially lethal infections, WELV represents a new challenge for public health. Ongoing research and monitoring will be critical in understanding and addressing this emerging threat.
