It's just Valley Fever which has been around these areas for at least decades. Unless they have evidence of increased incidence (which frankly I would not trust anyway), then this is just more empty fear porn. Also Valley Fever supposedly does not spread between humans. It's fungal and carried by the wind born spores and comes from the soil. Most people recover naturally without much problem but yeah, if your immune system has been toasted, it could be worse for you.
