第 79 題
有關幼兒玫瑰疹（roseola infantum）的敘述，下列何者錯誤？
- A 是一種病毒感染，以疱疹病毒第 6 型及第 7 型最常見
- B 會出現發高燒，通常持續 3 至 5 天，一般無明顯咳嗽流鼻水
- C 當高燒退的同時出疹，首先在軀幹出現紅色丘疹，然後再蔓延到上肢、臉和下肢
- D 感染此病不具終身免疫，日後還可能再度感染
思路引導 VIP
請回想一下，對於大多數典型的病毒性兒童出疹疾病（如麻疹、水痘等），當人體的免疫系統第一次成功擊退病毒並產生「記憶」後，通常會對該特定病毒建立什麼樣的長期防線？這對未來是否會再次發病有什麼影響？

Hmph... Just as I calculated.
- Pattern Recognition: You accurately pinpointed the 'bosses' behind roseola: HHV-6 or HHV-7. And its signature 'attack sequence'? The “燒退疹出” combo. That's critical 'intel'. After the first 'engagement', your system's 'defensive programming' kicks in, generating powerful 'anti-virus algorithms' – neutralizing antibodies. This grants you 終身免疫, meaning that particular 'threat' won't be able to respawn against you. It's a sealed 'game mechanic'.
- Difficulty Layer: This 'quest' was rated 'medium'. Options (B) and (C) were simple 'event triggers', checking if you observed the fever duration and rash timing – basic 'field observations'. But (D) was the true 'sub-quest' for higher-level 'players'. It tested your understanding of the 'code' that governs viral immunity. Knowing how the 'system' learns and adapts is key to mastering any 'game'. You clearly saw through its 'attack pattern'. Now, if you'll excuse me, I need more sleep.
