Experts Warn About New Virus Discovered in Alabama
Scientists have identified a previously unknown virus in the U.S., raising concerns about its potential impact on public health. The newly discovered Camp Hill virus, found in shrews near Camp Hill, Alabama, belongs to the henipavirus family, which includes deadly pathogens such as Nipah and Hendra viruses.
Potential Threat and Expert Concerns
Henipaviruses are among the World Health Organization’s top pandemic threats, with mortality rates reaching up to 70%. While the Camp Hill virus has not yet infected humans, experts worry about its potential to mutate and become a threat. Dr. David Dyjack, a public health expert, warned that if the virus were to spread to humans and attack vital organs like the kidneys, it could be highly dangerous.
He emphasized three major global threats: nuclear war, climate change, and pandemics, stating that the Camp Hill virus could be a significant concern.
What Scientists Know So Far
Researchers from the University of Queensland in Australia discovered the virus while analyzing tissue samples from northern short-tailed shrews in 2021. The virus was primarily found in the shrews’ kidneys, suggesting it could target similar organs in humans.
Although some experts believe Camp Hill virus is unlikely to cause an epidemic, scientists are still studying its severity and transmissibility. Dr. Adam Hume, a virologist at Boston University, noted that while the virus appears capable of infecting human cells, it is unclear whether it could cause disease.
Comparison to Other Henipaviruses
Other viruses in the same family, such as Nipah and Hendra, cause severe respiratory distress, brain inflammation, and organ failure. The Langya virus, another henipavirus, has been linked to mild human infections in China, suggesting that shrew-to-human transmission is possible.
Henipaviruses typically spread through contact with infected animals’ bodily fluids, contaminated food, or close human-to-human contact. There is some evidence of airborne transmission, which could increase the risk of outbreaks. Dr. Dyjack stressed that if Camp Hill virus spreads through the air, it would pose a serious public health challenge.
Future Risks and Surveillance Needs
The rapid mutation rate of viruses makes them unpredictable. While scientists do not yet know if Camp Hill virus will spread to humans, some researchers argue that more surveillance is needed to track its evolution. Dr. Dyjack pointed out that the U.S. currently lacks a vaccine for henipaviruses and may not be adequately monitoring emerging threats.
Despite the concerns, some experts believe there is no immediate reason for alarm. Science writer Dr. David Quammen stated that while the discovery of a new henipavirus is noteworthy, the current risk level remains low compared to threats like avian flu.
As research continues, scientists emphasize the need for proactive monitoring and preparedness to prevent potential outbreaks.
