What is the diagnosis of the following symptoms of a 2 month-old male baby and how was the disease acquired?

Question

He had a fever of 39.2 degrees Celsius, extreme irritability, and vomiting. His fontanelles were normal and his neck was supple. Cerebrospinal fluid revealed a white blood cell count of 75mm cubed with 72% neutrophils, 8% lymphocytes, and 20% monocytes. The glucose level and protein level was normal. A Gram stain was negative for bacteria. Cerebrospinal fluid viral culture proved positive for an enterovirus.

Answer 1

The spinal fluid is useful but you left out WBC with diff. I would suggest an encephalitis of viral origins and since you didn't include history of patient, certain encephalitic infections are carried by various species of mosquitoes, it is possibly Japan B encephalitis, that is why history of the patient is vital....enterovirus are quite common and can cause meningitis without sequela...usually! If you are presenting, a AP/Lateral would be useful. Your description of 'extreme irritability' is vague...to sound, to touch, or restlessness. Emesis is common in infants but is it continuous, intermittent, after feeding? Nucchal rigidity is more important in older patients where the muscles have have time to strengthen but are no so diagnostic with infants. If indeed the diagnosis is encephalitis of enterovirus origin, since enterovirus are the second most common virus in many areas, it would be difficult to guess...but you need the history.

I'm sorry you forgot to answer in the form of a question.
