That's really bizarre. Though I would have thought the qualifiers would have been the first ones to leave the Palm Springs area. Did they just bring the illness to Dallas? Didn't hear of retirements at that event. I didn't even expect men's qualies to begin play today. Everything starts one day earlier in the week than it did at IW. Also, from the OOP it looks like each court in use today has either exclusively ATP or exclusively WTA matches. I don't think I've seen that before at a mixed-gender event. Perhaps they just didn't feel like changing the nets/logos between matches?
