Scientists are sounding alarms about the spread of a new bird flu strain affecting livestock and humans. Over the past year, this virus has impacted more than 600 cattle herds and continues to spread through poultry and wild birds.
Dr. Juergen Richt, a veterinary microbiologist, initially hoped that controlling milk contamination on dairy farms would help contain the virus. However, the outbreak persists, and experts emphasize its resilience. “This virus is not easy to get rid of. We will have to live with it,” said Richt.
With limited control options, Gregory Gray, an epidemiologist, suggests that a widespread vaccine program may be necessary to prevent further spread among livestock. The virus poses particular risks to those working closely with animals, as studies show evidence of past infections among agricultural workers.
Dr. Deborah Birx, a pandemic response expert, highlights the lack of sufficient testing for cattle and humans. “The most important thing is to track where it is,” Birx stated, stressing the need for improved monitoring to gauge the outbreak’s full scope.
Although human infections have been mild so far, a concerning case in British Columbia revealed potential virus mutations that could enhance its ability to infect humans. Louise Moncla, a virologist, warned of the risks: “Flu is always going to surprise us. It is very hard to predict which viruses are going to infect people and how they will change when they do.”
As flu season begins, scientists fear the possibility of reassortment—genetic mixing between bird flu and seasonal influenza—that could create a more dangerous virus. While the probability of such events remains uncertain, vigilance and preventive measures are critical to limiting the virus’s impact.
Experts urge immediate action to track and control bird flu to protect public health and livestock industries.
