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: baby boy was the 675-g product of 23-3/7 week twin gestation born to primiparous mother. mother is a 28-year-old gravida 1 para 0 (now 1) mom, blood type a positive, antibody negative, rubella unknown, rapid plasma reagin nonreactive, hepatitis b status negative, group b strep unknown. benign antepartum until when mother was noted to be in labor with cervical changes in the obstetric office. mother was transferred to hospital, received betamethasone and magnesium sulfate, and was transferred to the for further management. upon arrival to the mother was noted to have further progression in her cervical dilatation which progressed rapidly with a vaginal delivery. no sepsis risk factors were noted with the exception of unknown preterm labor, unknown group b strep status, and extreme prematurity. the infant emerged vaginally with a spontaneous cry. he received bag and mask ventilation via mask, and the infant was intubated electively without difficulty in the delivery room. heart rate had always been greater than 100. the infant visited with parents briefly prior to transport to the newborn intensive care unit. apgar scores assigned as 7 and 8. physical examination on presentation: birth weight was 674 g, length was 32 cm, head circumference was 22 cm. physical examination was consistent with extremely premature infant with gelatinous skin and fused eyelids bilaterally. examination consistent with stated gestational age with some bruising on legs. well perfused and saturated on ventilator. coarse crackly breath sounds bilaterally. cardiovascular revealed normal first heart sound and second heart sound without murmurs. the abdomen was benign. genitalia were normal premature male, bilaterally undescended testes. anus was patent. neurologic was nonfocal and age appropriate. hospital course: respiratory: was intubated in the delivery room and received a total of two doses of survanta. within the first couple hours of age, the infant noted to have respiratory and cardiac decompensation associated with left pneumothorax which responded to neonatal thoracentesis. at that time, the infant was placed on high-frequency ventilation. later on in the morning, around 8: 30 a.m., the baby's status deteriorated again with re-accumulation of left pneumothorax resulting in bradycardia, hypotension, and hypoxemia. the infant was treated with needle aspiration of pneumothorax. chest compressions and epinephrine administered during an approximately 5-minute to 6-minute period of bradycardia prior to effective evacuation of pneumothorax. air continued to be removed from chest continuously. a cranial ultrasound performed at that time revealed a small grade 1 hemorrhage. the infant was started on ampicillin and gentamicin in light of a low absolute neutrophil count and increased concern for infection. complete blood count had a white blood cell count of 5.8, hematocrit of 48.9, platelets of 257 (6% polys, 0% bands, 93% lymphocytes). due to worsening condition, dr. met with the parents to review the infant's status with the high risk of mortality and worrisome long-term prognosis, risk of brain injury, and long-term developmental handicap in case of survival. after the discussion, the parents together expressed their decision to forego further intervention for the pneumothorax and to prioritize comfort measures. they also requested that both babies be baptized, and that their family join them in spending time with . continued on the ventilator for a period time, receiving fentanyl for pain management. at approximately 16:10, the infant was removed from the ventilator, per parents' request. the infant was held by both parents, and the infant was pronounced at 16:55. the family was offered the option of autopsy but declined. discharge disposition: deceased. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours insertion of endotracheal tube enteral infusion of concentrated nutritional substances thoracentesis umbilical vein catheterization diagnoses: observation for suspected infectious condition intraventricular hemorrhage, grade i extreme immaturity, 500-749 grams twin birth, mate liveborn, born in hospital, delivered without mention of cesarean section interstitial emphysema and related conditions 

Answer: The patient is high likely exposed to
