Researchers identify new tick virus linked to invasive Asian longhorned tick

The Hill reports that scientists identified a novel nairovirus in China linked to an invasive tick found across several U.S. states.

The short version

  • Scientists identified Asian longhorned tick nairovirus (ALTNV) in Chinese hospital patients who showed DBV symptoms but tested negative for that pathogen.[The Hill]
  • The Asian longhorned tick is an invasive species in the United States that has spread across more than two dozen states since 2017.[The Hill]
  • Experts state that the tick has not been known to transmit any diseases to humans within the United States so far.[The Hill]

Key facts

  • Researchers identified Asian longhorned tick nairovirus (ALTNV) after examining hospital patients in China who exhibited DBV symptoms but tested negative.[The Hill]
  • Over 15% of those examined patients in China tested positive for ALTNV.[The Hill]
  • The Asian longhorned tick was first detected in the United States in 2017 and has expanded across more than two dozen states.[The Hill]
  • Nearly all Asian longhorned ticks discovered in the United States are females able to reproduce without mating.[The Hill]
  • Dr. Douglas Norris reported that the tick transmits several pathogens to humans and animals in its native Asian range but has not transmitted disease to humans in the U.S.[The Hill]

What remains uncertain

  • It remains unknown whether the Asian longhorned tick will begin transmitting ALTNV or other pathogens to humans in the United States.[The Hill]
