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: is a former 31-weeks gestational age infant admitted to the nicu for prematurity and known prenatal hydronephrosis. he was born to a 28-year-old mother gravida 2, now para 2 with past medical history notable for gastroesophageal reflux and cholecystectomy. prenatal screens included blood type o positive, dat negative, hepatitis b surface antigen negative, rpr nonreactive, rubella immune, group b strep unknown, hiv negative, chlamydia negative, gc negative, and cf negative. mother is speaking. estimated date of confinement was placing the infant at 31 weeks gestation. pregnancy was complicated by moderate-to- severe right-sided hydronephrosis with possible duplicated collecting system. the latter was not confirmed on the most recent ultrasound. the left kidney and bladder were normal. oligohydramnios was noted over the past week of pregnancy with an afi of 5.5 for which an elective cesarean section was performed under spinal anesthesia. there was no labor, no intrapartum maternal fever, or other signs of chorioamnionitis. rupture of membranes occurred at delivery yielding clear amniotic fluid. the infant was vigorous at delivery. apgars were 9 at one minute and 9 at five minutes. baby was , and in no distress, and transferred to the nicu uneventfully. physical examination upon admission: revealed a weight of 1745 grams (75th percentile). length 42 cm (50th percentile). head circumference 29 cm (50th percentile). o2 saturation was 98 percent on room air. temperature 98.2, heart rate 148, respiratory rate 60-80, and blood pressure 64/36 with a mean of 45. heent: anterior fontanel is soft and flat, nondysmorphic, left ear pit. palate intact. neck and mouth are normal. normocephalic. no nasal flaring. chest: no retractions. good breath sounds bilaterally. intermittent mild grunting respirations. cardiovascular: well-perfused, regular rate and rhythm. femoral pulses are normal. normal s1, s2, no murmur. abdomen is soft, nondistended. right sided ballottable flank mass consistent with renal enlargement. bowel sounds are active. anus patent. liver 1 cm below the right costal margin. gu: normal male preterm genitalia. testes descended bilaterally. cns: active, alert, and responsive to stimulus. tone appropriate for gestational age. moves all extremities equally and symmetrically. gag intact. grasp and morrow symmetric. skin is normal. musculoskeletal: sacral dimples noted. clavicles intact. hips without clicks. summary of hospital course by systems: respiratory: initially was admitted in room air, but due to increase work of breathing, was placed on cpap of 6 cm with a max fio2 of 25 percent. he continued on cpap for the first 24 hours and transitioned to a nasal cannula oxygen with a peak flow of 300 cc. this was gradually weaned until day of life seven when he transitioned to room air. he has been breathing comfortably in room air since that time. had minimal evidence of apnea of prematurity with brief o2 saturation drifts and quick self- resolved bradycardia and apnea spells, the last of which was noted two weeks prior to discharge. cardiovascular: remained hemodynamically stable throughout hospitalization. a soft systolic murmur was noted, that remained at the time of discharge. cxr, ekg, and 4extremity bp on were within normal limits. the murmur was felt to be consistent with peripheral pulmonary stenosis, and will be followed as an outpatient. fen: was initially place on ivf, with enteral feedings introduced on day of life 2. enteral feedings were advanced without significant difficulty, and the infant reached full feedings on day of life seven at which time calories were increased to a maximum of 26 calories/ounce. patient was initially fed via gavage, and po and breast feeding were introduced as tolerated. by , infant was taking all feeds by mouth, with total intake of 150-180 cc/kg/day. with excellent weight gain, calories were decreased to 20 cals/oz. weight at time of discharge is 2.7 kg with a head circumference of 33.5 cm and a length of 47 cm. he continues to grow along the 50th percentile with unfortified breast milk. gi: required phototherapy for a peak serum bilirubin of 10.1 noted on day three. he continued under single phototherapy through day of life seven at which time it was discontinued for bilirubin of 4.5/0.3. a rebound was obtained on day of life eight, which was 3.7/0.3. this then was a resolved issue. heme/id: an initial cbc and blood cultures were obtained upon admission, and ampicillin and cefotaxime were begun. cbc was notable for a white count of 11.7 with 45 polys and 1 band, a hematocrit of 50 percent, and 292,000 platelets. blood cx were negative, and antibiotics were discontinued after 48 hours. last hematocrit was obtained on and was 30.8 with a reticulocyte count of 3.8 percent. was started on iron on day of life nine and continues to receive iron with a discharge dose of 0.25 ml by mouth each day. was also started on amoxicillin prophylaxis once the iv antibiotics were discontinued and continues on 50 mg of amoxicillin by mouth each day for hydronephrosis. renal: due to the history of prenatal hydronephrosis, urology and renal were consulted from . a renal ultrasound was obtained on day of life one, which revealed a moderate hydronephrosis on the right kidney with numerous cysts present. the right kidney was larger than the left. there was echogenicity noted bilaterally. there were no apparent cysts on the left kidney, but this could not be ruled out on this study. there was a normal bladder and no evidence of a duplex collecting system on either the right or the left kidneys. the right kidney measured 5.6 cm and the left kidney measured 4.1 cm. recommendation was for a repeat renal ultrasound and a vcug at two months of age, with follow-up with dr. from nephrology and dr. from urology. neurologic: a head ultrasound was obtained at a week of age and revealed a normal study. this was repeated at a month of age and continued to be normal at that time. has a normal neurologic exam. a sacral ultrasound was obtained given findings of sacral dimple on exam, and this was normal. sensory: audiology: hearing screening was performed on and was passed bilaterally. ophthalmology: rop screening was performed on revealing immature retinas to zone iii with a follow-up appointment recommended in three weeks from that time. psychosocial: family is speaking and has met with medical team with the assistance of an interpreter for continued newborn care and teaching, and discharge planning. condition on discharge: good. discharge disposition: home with family. name of primary pediatrician: dr. of medical care in , , at 100 . phone number is , fax . care and recommendations: feedings: feeds at discharge are breast milk, breast feeding with similac 20 all by mouth adlib demand. medications: iron 0.25 ml by mouth each day and amoxicillin 50 mg by mouth each day. car seat position screening: has not yet been performed, but will be done prior to discharge. immunizations received: hepatitis b vaccine given with consent on . immunizations recommended: synagis rsv prophylaxis should be considered from through for infants who meet any of the three criteria: 1. born at less than 32 weeks, 2. born between 32 and 35 weeks with two of three of the following: daycare during the rsv season, a smoker in the household, neuromuscular disease, airway abnormalities, or school-age siblings, or 3. with chronic lung disease. note: infant did not receive synagis in the nicu prior to discharge. influenza immunization is recommended annually in the fall for all infants once they reach six months of age. before this age and for the first 24 months of the child's life, immunization against influenza is recommended for household contacts and out of home caregivers. follow-up appointments: 1. pmd, dr. , in one day. 2. renal ultrasound and vcug: scheduled
