英國6/21發佈的統計數據是顯示delta的重症率高於alpha，不過疫苗有效 Public Health England said that the data showed there was a higher risk of hospital admission for patients with the delta variant compared with the alpha variant, but its analysis2 revealed that two doses of vaccine gave a high degree of protection against hospital admission, estimated to be more than 90%.
1.delta主要感染上呼吸道，所以導致重症的肺炎症狀會比較少
2.也因此delta突變是朝流感化邁進
3.莫德納疫苗證明能有效抵抗delta
唯一比較憂心的是delta容易感染年輕人，因此更增加了傳染能力
"李秉穎提到，資料顯示感染Delta變異株的症狀是流鼻水等類似感冒症狀，顯示病毒只在鼻子上呼吸道處，沒有能力攻擊下呼吸道導致嚴重肺炎與高死亡率，這可能是好的發展。"
我是滿常對他說的話有疑慮的啦那篇是28的新聞，但昨天張上淳有列表格說症狀沒有特別不一樣，而且那表格還顯示了delta的呼吸困難比例比較高

如果用全部案例去看，症狀比率應該不一樣，畢竟感染族群也會影響數據。
要是沒疫苗感覺就是要塞爆醫院
