Chinese scientists identify new tick-borne virus ALTNV; carrier already in US
A newly discovered virus spreading in China causes severe illness in coinfection cases, and the Asian longhorned tick that carries it has already established itself across US states.
What to know
- Chinese researchers identified a new tick-borne virus (ALTNV) causing flu-like illness; coinfection with another tick virus raises fatality rates to 18.4 percent.
- The Asian longhorned tick carrying ALTNV has spread to more than two dozen US states since 2017, though the virus has not yet been detected in American ticks.
- ALTNV alone typically causes fatigue and gastrointestinal symptoms with full recovery, but dual infection triggers severe respiratory and kidney complications.
- Public health experts emphasize the need for vigilance and improved diagnostic testing as the vector tick is already established in US ecology.
“A single female doesn't even need to mate—she can clone herself and lay thousands of eggs on her own. That's how populations explode so fast.”

Health media raises public awareness questions about US risk
Coverage from The Hill posed the question "Should we be concerned?" about the virus detection in the invasive tick species already present across US states, prompting wider public discussion about transmission risk.

Asian longhorned tick confirmed as ALTNV vector; already in US
ALTNV was found in 1.3 percent of nearly 47,500 ticks sampled across 15 Chinese provinces, primarily Haemaphysalis longicornis (Asian longhorned tick). Lab tests confirmed this species can transmit the virus to mice. The tick has already spread to more than two dozen US states since first being discovered in the country in 2017, though ALTNV has not yet been detected in American ticks.
“Americans shouldn't tune this out. We haven't found this virus in American ticks yet, but the tick that carries it has already made itself at home in…”

background
ALTNV causes flu-like illness; severe outcomes in coinfection cases — ALTNV alone typically causes fatigue, gastrointestinal problems, low platelet counts, and elevated liver enzymes, with patients recovering fully. However, when coinfected with Dabie bandavirus, patients showed higher rates of respiratory symptoms (61 percent versus 38 percent alone) and kidney impairment. Among 38 coinfected patients, seven died—an 18.4 percent fatality rate.

background
Chinese researchers identify new tick-borne virus ALTNV — Scientists at the State Key Laboratory of Pathogen and Biosecurity in Beijing published findings in The New England Journal of Medicine identifying Asian longhorned tick nairovirus (ALTNV). Of 3,163 patients tested, 10.4 percent were positive for ALTNV; among those testing negative for Dabie bandavirus, the rate rose to 15.1 percent.
