Polio virus infection can result in all except ?
**Core Concept**
Poliovirus infection is a significant public health concern, leading to various clinical manifestations due to the destruction of motor neurons in the spinal cord. The virus primarily targets the anterior horn cells of the spinal cord, leading to flaccid paralysis.
**Why the Correct Answer is Right**
Poliovirus infection can cause a range of symptoms, from mild to severe. The most common manifestation is aseptic meningitis, characterized by inflammation of the meninges without a bacterial infection. Additionally, poliovirus can cause paralysis, which can be permanent in some cases. The virus can also lead to bulbar poliomyelitis, affecting the brainstem and causing symptoms such as difficulty swallowing, breathing, and speaking.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because poliovirus infection is not typically associated with Guillain-Barré Syndrome (GBS), an autoimmune disorder that occurs after an infection triggers the immune system to attack the peripheral nerves.
**Option B:** This option is incorrect because poliovirus infection is not typically associated with Multiple Sclerosis (MS), a chronic autoimmune disease that affects the central nervous system.
**Option C:** This option is incorrect because poliovirus infection is not typically associated with Lyme disease, a bacterial infection caused by Borrelia burgdorferi.
**Clinical Pearl / High-Yield Fact**
Poliovirus infection can lead to long-term consequences, including residual paralysis and muscle atrophy, even after recovery from the initial illness. It is essential to recognize the clinical manifestations of poliovirus infection to provide prompt and effective treatment.
**Correct Answer: D. Lyme disease**
