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: maternal laboratory studies were a+, hepatitis b surface perinatal history: the mother progressed to spontaneous vaginal delivery secondary to preterm labor in the setting of concerns over the possibility of chorioamnionitis. the infant was born at 31 weeks gestation. the infant emerged with decreased tone, initially some mild respiratory efforts, heart rate of 100, but then required some bag mask ventilation in order to maintain sufficient respiratory effort. the patient responded well to these attempts and was taken to the neonatal intensive care unit for further management. apgar scores were 6 at one minute and 8 at five minutes. physical examination: on admission this was a pink, nondysmorphic infant, blow-by oxygen, well perfused and saturated. there was a flat anterior fontanel with the exception of the presence of some alopecia on the right temporal region. there was no skull defect. the skin was intact. no other lesions were noted. the clavicles were intact. the cardiac examination revealed normal s1 and s2 without murmurs. the lungs had fair and equal air entry bilaterally. the abdomen was benign. there was no hepatosplenomegaly or organomegaly. there was normal genitalia in this infant with well-descended left testis, unable to palpate the right. hips were normal. the spine was intact and the neurological examination was nonfocal with appropriate tone and reflexes for age. measurements: birth weight was 1,830 grams (75th percentile). length was 42 cm (around the 55th percentile). head circumference was 26.8 cm which was then repeated around 29 cm putting him between the 25th and 50th percentile for gestational age. summary of hospital course by systems: 1. respiratory: had some retracting and increased work of breathing after delivery and was briefly on cpap and then weaned over 24 hours to room air, and has remained on room air for the remainder of his hospital stay. he did have some evidence of respiratory immaturity consistent with gestational age. he was briefly on caffeine. this was discontinued on the 11th day of life. he has had minimal apnea since then and has been free of apnea for over a week prior to discharge. 2. cardiovascular: the patient has a murmur which was initially quite loud and now has become softer consistent with peripheral pulmonic stenosis and confirmed by echocardiogram. his examination reveals a pink, warm and well-perfused infant. his last hematocrit was 30 on , and there have been no other concerns from a cardiovascular standpoint. 3. fluids, electrolytes and nutrition: his weight today is 2,645 grams. head circumference is 32 cm. he is taking 50-70 cc of enfamil 24 calorie or breast milk supplemented to 24 calories ad lib, and he is achieving at least 130 cc per kg per day of intake on an ad lib basis. over the last 24 hours he took about 160 cc per kg per day. by himself he is waking up to feed. he has had no other concerns for fluid and electrolyte issues. 4. dermatologic: he does have a sebaceous nevus on his scalp. he has had a consultation with dermatology for cosmetic purposes. this area can be surgically removed when he gets closer toward childhood but it is not any source for concern at the present time. 5. neurological: he had normal head ultrasounds early in life and he needs a 30-day ultrasound which can be scheduled as an outpatient. 6. almologic: his most recent examination showed immature retina but normal vascularization out to zone 3 in both eyes. he needs a follow up in two weeks with dr. at . 7. gastrointestinal: he has some neonatal jaundice with a peak bilirubin of 9.1 on day of life three. he received about 3-4 days of phototherapy and has not been on phototherapy since then. this was discontinued around day of life six to seven. he has had no other major problems of feeding intolerance. 8. infection: he had a seven-day course of antibiotics due to concerns of maternal chorioamnionitis. blood and cerebrospinal fluid remained unremarkable and the antibiotics were discontinued after seven days. approximately one week prior to discharge he had an episode where he had increased periodic breathing and a concern for possible sepsis and received a short course of antibiotics. work-up was also negative and he has been clinically well since that time with no other concern for sepsis. 9. ry: a. audiology: a hearing screen was performed with automated auditory brainstem responses. b. ophthalmology: the infant's eyes were examined as mentioned above and were found to be immature but at zone 3. follow up in two weeks should be with dr. at . condition at discharge: good. discharge disposition: home. primary pediatrician: dr. with pediatrics, phone #. she has been informed. she is looking after this baby's older sibling and follow up can be arranged for tomorrow or the day after. care recommendations: 1. feeds at discharge: enfamil supplemented to 24 calories per ounce or mother's mild supplemented with enfamil powder at 24 calories per ounce given on an ad lib basis. 2. medications: fer-in- 0.2 cc daily. 3. car seat position screening is being done. 4. state newborn screening status: immunizations received - the infant is getting synagis and hepatitis b vaccine. immunizations recommended - synagis rsv prophylaxis should be considered from through for infants who meet any of the following three criteria: 1. born at less than 32 weeks gestation. 2. born between 32 and 35 weeks with plans for day care during the rsv season, smoker in the household or with preschool siblings. 3. with chronic lung disease. influenza immunization should be considered annually in the fall for preterm infants with chronic lung disease once they reach six months of age. before this age the family and other caregivers should be considered for immunization against influenza to protect the infant. folp appointments scheduled and recommended: 1. follow up with dr. tomorrow or the day after discharge. 2. visiting nurse is to be arranged for two days following discharge for a weight check. 3. follow up with dermatology regarding nevus sebaceous on a p.r.n. basis. 4. follow up with dr. at in two weeks for repeat eye examination. 5. follow up this week at as an outpatient for head ultrasound. discharge diagnoses: 1. former 31-week premature infant now corrected to 35 weeks gestation. 2. history of mild respiratory distress resolved. 3. history of neonatal jaundice resolved. 4. sepsis evaluation completed. 5. nevus sebaceous. , m.d. dictated by: medquist36 procedure:
