Infectious Disease Experts Warn Bird Flu Outbreak Bigger Than Previously Thought

For weeks, the dairy industry has been gripped by a highly contagious virus that is threatening to only get worse. Federal regulators announced this week that samples of pasteurized milk tested positive for H5N1, thethat the country’s milk supply is safe thanks to the pasteurization process, which works by heating milk to kill bacteria and viruses, and “the diversion or destruction of milk from sick cows.

In the most recent confirmed human case, the virus spread from a cow to a human; which is the first time cow to human transmission has happened. The last time a human tested positive for H5N1 was in, one major concern is that the more it jumps from animal to animal, or animal to human, the more likely it is to mutate to become more effective at infecting humans.

He added there is no guidance on asymptomatic cattle testing either. However, dairy farmers, Rajnarayanan said, will likely see signs that their herds are infected without testing. In the confirmed infected cows with H5N1, their milk production dropped and turned yellowish. “But what about beef cattle?” Rajnarayanan asked.via email that more testing needs to be done — especially among asymptomatic cows, beef cattle and cows in states with no known cases.

“As well as the fact that many people at the greatest exposure risk may be undocumented, discouraged from reporting by their employers, and not have access to health care,” she added.

Disease X: The Unknown Infectious ConditionDisease X is the label that the World Health Organization uses to refer to some currently unknown infectious condition that is capable of causing an epidemic or – if it spreads across multiple countries – a pandemic. The term, coined in 2017, can be used to mean a newly discovered pathogen or any known pathogen with newly acquired pandemic potential. The World Health Organization warns about the risks of future pandemics and emphasizes the importance of preparation.
