國內疫情什么時候結束,2020年過了一大半了?

更新時間:2021-08-25 11:44:40作者:admin2

1、目前只有控制疫情傳播的措施,而缺少有效殺滅人體內19-CoV病毒的手段。確診和疑似病例人數都達到1W+,但治愈人數才200多例,且治愈病人存在再感染風險,患病人數增長速度遠超康復速度;
2、非典從02年12月爆發到03年7月結束,歷時8個月。本次疫情與非典差不多是同一時期爆發,雖然死亡率低,但是傳染性更強,病人數量更多,持續時間可能要遠超8個月;
3、非典是到7月份突然消失的,目前都不清楚是什么原因,推測可能原因是天氣轉暖,溫度升高,阻斷了傳播,但是這種情況對19-nCoV肺炎病毒不一定適用;
4、極端情況是疫情失控,在全球流行,像人口密集、防控條件較差的東南亞、南亞地區極有可能,病毒傳播過程中發生變異,新研制疫苗失效,這種情況下疫情結束遙遙無期。
