How Now, Brown Cow

Medical Discovery News Season 20 Episode 952

Welcome to Medical Discovery News.  I’m Dr. Norbert Herzog. 

 And I’m Dr. David Niesel 

The next big pandemic threat that scientists hope to prevent is the H-five-N-one avian influenza virus. 

 The same virus has infected over two hundred dairy cow herds in at least fourteen states. And as of this recording, sixteen people have tested positive for the virus. 

 All but one farm worker had direct contact with infected animals. And the one case in Missouri with no animal contact is still untraceable. 

 The concern is that as this virus has become more adept at spreading among dairy cows and as more farmworkers get the virus, it could mutate to infect humans easily. 

 The virus was first identified in the nineteen nineties in Southern China’s farm birds. Since then, it has become the dominant strain of bird flu in bird populations worldwide. Millions of wild and domestic birds have died and three years ago, it began infecting chickens in the US and eventually, dairy cows.

 As for humans, the first human deaths were reported in Hong Kong in nineteen-ninety seven.  Overall, nearly nine hundred human infections worldwide have been reported with over half being fatal.  

Even with this knowledge, some people still drink raw milk. Most commercial milk is pasteurized which heats milk to high temperatures killing pathogens such as viruses including H-five-N-one flu virus. 

 Scientists are closely monitoring the spread of H-five-N-one, and we hope we won’t have to face the threat of another epidemic or worse, pandemic.
