COVID-19/SARS-CoV-2は、軽症でも何度も感染繰り返し免疫細胞に欠損を起こす感染症です。
回復中の人の骨髄の免疫を造る細胞から白血球を造る細胞やIL-6を造る細胞が増えていて炎症を起こし易く成っていると言う事です。
B細胞T細胞と言う免疫に関わる細胞に影響を与える事で免疫力低下させているが中和抗体も出来ますがVirusが変異している為に何度も感染繰り返し免疫力を低下させて行きます。
免疫細胞が欠損すると言う意味は、免疫力低下して他の感染症にも感染し易く成ると言う事です。

The immune system and long COVID
The journey to severe or long COVID could be established immediately after infection, or at the latest when symptoms appear, according to new research.
