New Viruses Threaten Global Health Crisis
5 Feb
Summary
- Influenza D and canine coronavirus can jump from animals to humans.
- Surveillance for these viruses is lagging, creating a dangerous blind spot.
- Lack of diagnostics and vaccines makes these pathogens a major threat.
Infectious disease experts are sounding the alarm over two animal pathogens, influenza D and canine coronavirus, that show potential for triggering a major health crisis. These viruses are increasingly observed transitioning from animals to humans, yet current surveillance efforts are lagging, creating a critical blind spot.
Influenza D, which affects various livestock and wildlife, is no longer confined to animals, with studies showing high antibody prevalence in cattle workers. While not yet symptomatic in humans, a strain in China has demonstrated person-to-person transmission capabilities.
Canine coronavirus (CCoV), typically causing gastrointestinal issues in dogs, is also evolving. New strains are now targeting the human respiratory system, with documented cases in Southeast Asia and Arkansas, some linked to pneumonia hospitalizations.
Researchers highlight that the limited data available are cause for concern, emphasizing the urgent need for more diagnostic tests, improved surveillance systems, and effective countermeasures to mitigate the public health threat posed by these adaptable pathogens.
