I use oxygen 24/7 as we;; as a bronchodilator as needed.

HI Wylma. Valley Fever is not super common, but it is a risk and something you are right to be concerned about. I am not a medical expert, but I lived in the Phoenix area for five years. From what I recall, people with reduced immunity are at the highest risk for infection. Here is some information about Valley Fever rates in Maricopa County, where Phoenix is located: https://www.maricopa.gov/5813/Valley-Fever. Keep in mind as you read those figures that the county's population is 4.5 million. Will you be indoors most of the time? If so, the air conditioning should at least limit your exposure. Could you ask your doctor to contact a pulmonologist in Arizona for advice? Will your granddaughter have a lot of other support at graduation? If are worried about Valley Fever, maybe someone who is attending can livestream it for you (or at least her turn crossing the stage) and then you can have a video call with her after.
Hopefully, some members who live in Arizona will chime in with their experiences and input. Congratulations to your granddaughter! - Lori (Team Member)

I was diagnosed and treated for Valley Fever in 1989 while I was in my 3rd trimester of pregnancy, which come to find out is a "high risk" group for this fungus disease of the lungs. Keep in mind, there are many people that test positive for valley Fever, but have no idea that they ever have had it. Anyway, I was pretty bad, worse then a really bad bronchitis, treated with antifungal medications, breathing treatments and inhaler, it took a couple weeks and I had pulled muscles from coughing so bad.
Valley fever is a soil born disease, in dessert regions water does not soak in to the ground very fast, it sits there and of course starts growing fungus (molds and mildews). These fungus spores then become airborne during storms, strong winds, construction, farming etc.... once airborne or you are playing in the dirt and when you are contract it by breathing the fungus in. Again many people that do get it have no idea they ever had it, then the majority of people that have been exposed has Never caught it. Wearing a mask while you are outside could be very helpful I would think. Since I contracted and treated for Valley Fever there is a secondary chance of another infection if I was to use Biologic Medications, other then that I have been back to AZ several times since we moved away and never caught or had problems with Valley Fever again. I have and will do so again contact those via phone if I have any questions that have not been previously answered by other conversations with one or the other. Links below. No matter what, it will still be your choice of rather you wish to go or not. I hope the best for you and would support you either way you choose.
