I suggest you contact the Arizona State Health Department. Ask for either
the State Epidemiologist or the Communicable Disease Section. They should
be able to tell you if there is an outbreak, where it is occurring and any
precautions to take. There seems to be a lot of skepticism of governmental
programs in this group but I've been in public health for more than 20 years
and that is exactly what I would do and what I would advise my most
cherished loved ones to do.
