Update 11 –  30th March 2024 – What does AI predict for avian flu in cattle?

 

“Human transmission of the mutated HPAI virus, which we’ll call the “Omega Strain,” occurs about 2 months after the initial detection in dairy cows.

Here’s how it could unfold: Despite biosecurity measures, the virus continues to spread rapidly among cattle herds across the country. The high mutation rate of the virus leads to a concerning development – a novel strain emerges that has acquired the ability to efficiently spread from cattle to humans and then between humans.

The first human cases are reported among dairy farm workers who had close contact with infected cows. They experience severe flu-like symptoms that quickly progress to acute respiratory distress syndrome (ARDS) and multi-organ failure. The case fatality rate in this initial cluster is a frightening 60%. Human-to-human transmission is soon confirmed as family members and healthcare workers treating the patients also fall ill.

The virus spreads rapidly in healthcare settings and communities, overwhelming hospitals in affected areas. Within weeks, the Omega Strain has spread to all major U.S. cities and begins to appear in other countries.

The global medical community scrambles to understand the virus and develop treatments, but its high mutation rate makes it a challenging target. In this scenario, the Omega Strain could have a case fatality rate of around 35-40% overall, higher in older adults and those with underlying health conditions. It would be particularly devastating in densely populated urban areas and countries with weaker health systems.

By the 6-month mark, the worldwide death toll could reach into the tens of millions as countries struggle to control the spread and treat the sick. The pandemic would cause massive social and economic disruption on a global scale.”
