Feb. 16, 2006 Dust-Storm Related Fatalities A thick cloud of dust caused two traffic pileups on a stretch of Interstate 8 south of the Valley on Wednesday morning, leaving two people dead and 13 others injured.

  6. Valley Fever Update ARIZONA DAILY STAR, Tucson, Arizona Mar.12, 2006 Dr. Eskild Petersen, longtime infectious-disease specialist at the University of Arizona: Valley fever severity rises to level that is 'unbelievable' Dr. John Gagliani, UA’s Valley Fever Center for Excellence “This is a very different, very unusual year." Valley fever infections rising steadily in Arizona since late 1990s In Pima County, 259 cases from November through January (183 cases reported during the same period last year). “We usually don't get more than one or two new cases a month," said Petersen. "I've never seen that number in so short a time. And it's not just at our clinic. It's the general feeling out there that something very serious is happening. We will easily surpass 4,000 cases statewide this year.” REASoN Program Review, 14 March 2006

  7. The timing of this current spike jibes exactly with the onset of an extreme dry period in Southern Arizona.That was the final step in what we call the "grow and blow" weather pattern now known to trigger outbreaks of valley fever. The pattern requires a period of sufficient moisture to grow the infectious fungus in the soil — and that happened last winter — followed by a severe drought to get the fungal spores up into the air. Other factors pushing the outbreak include the influx of ‘newbies’, home-building boom on the outskirts of the cityIt appears the valley fever outbreak now affecting Tucson humans may be attacking our canine friends as well.
