Does the us have bird flu under control
It's hard to tell
Even though it's been close to three months
Since the virus was still spotin dairy catatle
New cases are still cropping up most recently in wioming and texas
This week federal health agencies released several new assessments of the situation and prs will stone es here to tell us the latest day
Well here there
So what did we learn from these latest reports
Well we got a better sense of how bird flu is spreading between different dairy farms
That the virus has been detected
And we did a deheds in a dozen states
Since late march
Many these cases were in michigate the usda drill down into what's happening there
They found it mainly been transmitted from her to heard in three ways
So first through shared the quiitment and vehicles
Second people are caring the virus in adverddently under clothing or boots
And finally some animals that are infected
Are moving between farms
There had been concerned that wildbirds could be repeatedly reintroducing the virus into dairy fattle
So far
Federal officials say
The evidence does not support that based on genetic sequencing of viral samples
It appears there was a single spillow ver vanta
When a wild bird spreadad into cattle in taxes sometime last year
And that sparked this unprecedented nationwide outtraak in dairy cattle right was in beyond animals
Though i know a few humans have contracted this flu
Which has some folks concerned about the sparking of pandemic
So we have any better sense of the risk of people
People
So right now federal health official say
The risk k the gengeneral public remains though if you work with dairy cattle
Obviously the risk level is higher
There's still only been three human cases reported the most recent one was in michiggan dairy worker
That was more concerning
Because the person actually had respiratory symptoms
I was ked cencenbeen for disease control in prevention this week
Whether there were any alarming mutations in the samples of the virus
They collected from that person
There's what doctor neuof shaw with with ccc c told me see any signs in the viruses
Fingerfriance that suggest that it's more able to transmit between human or from animals to humans
So clearly that is reassuring
But without a doubt
There are people in public health
Who are deeply worried about the situation at the fact that we don't have more visibility around the sounbreak are there unkknowns that have public health officials concerned
There's a lot of for starters brought up many big cattle or infector
Right now we don't know i asked the cdc
If we even have some sense of the trajectory
Here have we hit the peak of cases in cattle
The answer is also we don't know andrew pekkshsh brought up another big concern
And i spoke to him
Which is better surveillance on the human side of things
A pekosh is a viologist at john hopkins bblueberg school of public health
That's really the critical thing that were now worried about
Is it is virus gets into humans
Then the virus can adapt two humans
Directly
This has been going on long enough
So that there should be annobody signature in the blood of people who have gotten exposed
And that would really give us a sense of how much low level exposure perhaps mild disease has been in this population
So basically figuring out
How many cases we might have mised by looking for eedence of of a pasininfethat
That can help us gage the overall risk to humans
A pegarsasays still seems ms within overheard the virus is primarily spreading in the process of milking
It could be the virus just keeps doing that
And doesn't end up adapting to spread from human to human
But we can keep it from infecting other people
But that's optimistic and oversomething we can bank on that's amp or health correspond

Thanks
Well
Thank you
