痘 (pox, smallpox)

その幼稚園で水痘が流行っている。

Chickenpox are spreading at that nursery.

執匙の高階経由は痘瘡の治療経験が乏しかったため、経験豊富な西尾兼道・久野恭（いずれも小児科医）を召集して拝診に参加させた結果、いよいよ痘瘡の疑いは強まり、17日に武家伝奏などへ天皇が痘瘡に罹ったことを正式に発表した。

As Takashina Tsunenari, the physician in charge, had little experience in treating smallpox, experienced Kanemichi Nishio and Kyo Hisano, both pediatricians, were summoned to join the examination, which strengthened the suspicion of smallpox, and on the 17th it was officially announced to the Buketenso and others that the Emperor had smallpox.
