A 10-day-old female neonate is presented to an outpatient clinic with a chief complaint of persistent eye redness and a progressive mucoid discharge from both eyes that began around 5 days prior. Her mother, who had no documented prenatal care until late in the third trimester, also reports the baby has developed a dry cough and occasional nasal congestion over the past three days. The infant received routine ocular prophylaxis with silver nitrate immediately after birth. Physical examination reveals an afebrile infant with a temperature of 37.0°C, blood pressure of 85/50 mmHg, heart rate of 140 beats/min, and respiratory rate of 40 breaths/min with oxygen saturation of 97% on room air. Ophthalmic examination shows significant bilateral eyelid edema and mucoid, sticky discharge with conjunctival injection; no corneal ulcerations or vesicles are noted. Lung auscultation reveals fine crackles bilaterally, particularly in the lower lobes. Abdominal and skin examinations are unremarkable. Laboratory investigations show a white blood cell count of 16.5 x 10^9/L, hemoglobin of 140 g/L, and platelets of 350 x 10^9/L. C-reactive protein is 25 mg/L. A chest radiograph demonstrates diffuse peribronchial thickening and patchy infiltrates with hyperinflation. What is the most likely etiological agent and the primary management strategy, along with a crucial complication to monitor for in this infant?

A 4-day-old male neonate is brought to the community hospital emergency department by his mother due to progressive eye discharge and increased irritability since yesterday. The mother, G2P1, received no prenatal care for this pregnancy. She reports a history of sexually transmitted infections in a previous relationship but denies active infections. The infant was born via spontaneous vaginal delivery at term after a prolonged labor complicated by early rupture of membranes. On examination, the neonate appears lethargic but is arousable, with a temperature of 38.0°C (100.4°F), heart rate of 160 beats/min, respiratory rate of 50 breaths/min, and blood pressure of 60/35 mmHg. Both eyes show significant bilateral periorbital edema, marked conjunctival erythema, and copious, thick, yellow-green mucopurulent discharge. Mild generalized hypotonia is noted. His fontanelles are soft and flat, and lung sounds are clear. The rest of the physical examination is unremarkable. Considering the clinical presentation and maternal history, what is the most likely diagnosis and the immediate, empirical management strategy for this neonate?

A 3-day-old male neonate presents to the emergency department with a 12-hour history of worsening bilateral profuse purulent eye discharge, marked eyelid edema, and significant conjunctival hyperemia. His mother, who had no prenatal care, delivered him at home at 39 weeks gestation. The infant appears irritable but is otherwise well-perfused. His temperature is 37.0°C, heart rate 135/min, respiratory rate 40/min, and oxygen saturation 99% on room air. The physical examination is notable for severe ocular findings, with sticky, matted eyelids and a copious greenish-yellow discharge. Which of the following represents the most likely diagnosis and the most appropriate immediate therapeutic intervention?
