I had an oral exposure around 6 months ago, one month ago my wife started complaining about nausea, fever, weakness and body pains, i took her to the doctor and she was given antibiotics and after 2 days she developed rashes all over the body, we returned to the doctor and she was given other meds. the rashes dissappeared but still the skin is rough. This is about a week ago. She has pains in the ribs while breating or coughing. The symptoms are cough, nausea and body pains more than 1 month, weakness and occassional fever. Please is this something to worry especially knowng that she has very weak immune system, could her signs appear after 5 months.
