Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: history of present illness: the patient is a 34-year-old woman gravida 2, para 0 who was admitted on at 31 weeks 5 days gestation with preterm labor with the above-mentioned history. the patient has been followed for prenatal care by me. her prenatal issues were as follows. positive hiv status with last cd4 count in of 559--the viral lode on was 83. the patient has been diagnosed with positive hiv status for over five years. during this time, the patient refused to be on antiretroviral therapy. during this pregnancy, however, she was counseled extensively regarding the decreased incidence of hiv transmission to the fetus with antiretroviral therapy and low viral lode. the patient agreed to be placed on combivir one tablet p.o. b.i.d. as well as viramune 200 mg p.o. b.i.d. the patient had been compliant with her medication. hepatitis c--the patient was diagnosed approximately two years ago. her liver function tests during this pregnancy had been stable. multiple history of endocarditis--the patient has been hospitalized numerous times and her most recent episode was approximately two years ago. at that time, the patient was found to have severe mitral valve regurgitation. her most recent echocardiogram which was performed during this pregnancy demonstrated minimal right ventricular systolic function. her left ventricular function was intact. history of substance abuse--the patient is currently on a methadone treatment program requiring 95 mg b.i.d. past surgical history: left knee surgery, right arm surgery for drainage of abscess. medications: digoxin 0.25 mg p.o. q.d., combivir one tablet p.o. b.i.d., viramune 200 mg p.o. b.i.d., xanax 0.5 mg p.o. q.h.s., methadone 95 mg p.o. b.i.d., bactrim ds one tablet q.d., folic acid 2 mg p.o. b.i.d., prenatal vitamins at one tablet p.o. b.i.d., ferrous sulfate 325 mg p.o. b.i.d. physical examination on admission: the patient was in no acute distress. the patient was afebrile with stable vital signs. general examination was within normal limits. cardiovascular examination demonstrated holosystolic murmur with possible s4 gallop. abdominal examination demonstrated soft, nontender abdomen with gravid uterus. extremities revealed trace pedal edema. vaginal examination demonstrated 1.5 cm dilatation with 70% effacement. fetal heart rate was in the 130s with variability. hospital course: the patient was admitted for observation with initial administration of magnesium sulfate for preterm labor. the patient was also given betamethasone earlier during this pregnancy. the patient was monitored on the antenatal floor and was subsequently weaned off magnesium sulfate. the patient remained stable with intermittent contractions but without cervical change. the fetal status was closely monitored during her admission and remained stable. during the hospitalization, however, the patient continued to have irregular intermittent contractions throughout and the fetus continued to remain in breech presentation. on , the patient underwent primary cesarean section for continued uterine contractions at 33 weeks and 4 days of gestation. the cesarean section was performed under spinal anesthesia without complication. the patient was admitted to the surgical intensive care unit for 24 hours of observation. the patient was subsequently transferred to the postpartum floor. her postoperative course was uneventful. she remained stable cardiovascularly and recovered well from surgery. the patient was discharged on on postoperative day #5. discharge medications: combivir one tablet p.o. b.i.d., viramune 200 mg p.o. b.i.d., digoxin 0.25 mg p.o. q.d., methadone 95 mg p.o. b.i.d. discharge followup: the patient is to follow up with me for postpartum care. she is also to be followed up by dr. for her cardiac issues. the patient also will be followed in the methadone clinic as well as by the infectious disease service for her hiv issues. , m.d. dictated by: medquist36 procedure: venous catheterization, not elsewhere classified injection of steroid incision of adrenal gland low cervical cesarean section other fetal monitoring other artificial rupture of membranes injection of antibiotic diagnoses: congestive heart failure, unspecified human immunodeficiency virus [hiv] disease tricuspid valve disorders, specified as nonrheumatic early onset of delivery, delivered, with or without mention of antepartum condition outcome of delivery, single liveborn anemia of mother, delivered, with or without mention of antepartum condition other cardiovascular diseases of mother, delivered, with or without mention of antepartum condition breech presentation without mention of version, delivered, with or without mention of antepartum condition drug dependence of mother, delivered, with or without mention of antepartum condition 

Answer: The patient is high likely exposed to
