Head scratcher on H1N1 in Amarillo

Surprised. Puzzled. A little concerned.
Those are all ways to describe how Amarillo public health officials feel when thinking about why their city has not seen any cases of H1N1, the virus commonly called swine flu.
“Right now, we haven't been able to find an explanation as to why that's the case,” Amarillo Public Health Department Director Matt Richardson said.
State health officials have confirmed more than 4,200 H1N1 cases and almost 200 more are still pending.
Still, none have appeared in Amarillo and only one – a recently confirmed case in Hemphill County – has shown in the Panhandle.
Other West Texas cities, Lubbock, Abilene, San Angelo and Wichita Falls, have reported multiple cases. None still in Amarillo.
Why?
Health officials can offer a few possible reasons, but they say there is no scientific reason as to why the virus shouldn’t have appeared locally nearly four months after it first showed in the state.
Only a relative handful of flu cases are tested for H1N1; those patients who are hospitalized with flu-like illness.
“Certainly in Amarillo, we don’t have as many of those as other communities,” Richardson said.
He and other Amarillo health officials have asked state and regional experts to explain why Potter and Randall counties don’t have H1N1 cases.
Still no answer has been given.
