Your wife's symptoms do not sound like those of an acute HIV infection, but even if they did, the odds would be against it; even classical acute HIV symptoms
usually are caused by other, more common
viral infections. Further, it is pretty much impossible that you caught HIV, transmitted it to your wife, and she developed symptoms all within 2 months since your last negative test. Further, most sex workers -- including those in India (if your username means you live there) -- do not have HIV.
