Results

The number of patients treated in the hospitals during the same early period of each wave differed (2351 in wave 4 vs maximum 6342 in wave 3); however, 68% to 69% of patients presenting to the emergency department with a positive COVID-19 result were admitted to the hospital in the first 3 waves vs 41.3% in wave 4 (Table 1). Patients hospitalized during wave 4 were younger (median age, 36 years vs maximum 59 years in wave 3; P < .001) with a higher proportion of females. Significantly fewer patients with comorbidities were admitted in wave 4, and the proportion presenting with an acute respiratory condition was lower (31.6% in wave 4 vs maximum 91.2% in wave 3, P < .001). Of 971 patients admitted in wave 4, 24.2% were vaccinated, 66.4% were unvaccinated, and vaccination status was unknown for 9.4%.

The proportion of patients requiring oxygen therapy significantly decreased ( 17.6% in wave 4 vs 74% in wave 3, P < .001) as did the percentage receiving mechanical ventilation (Table 2). Admission to intensive care was 18.5% in wave 4 vs 29.9% in wave 3 (P < .001).

The median LOS (between 7 and 8 days in previous waves) decreased to 3 days in wave 4. The death rate was between 19.7% in wave 1 and 29.1% in wave 3 and decreased to 2.7% in wave 4.

• 這個是茄子轉發新聞的數據來源。其病死率是以住院病例為基數算出來的。 -fuz- ♂ (0 bytes) () 12/31/2021 postreply 17:02:37

• 所以，2.7%是Omicron的住院死亡率。 相比之下，根據美國CDC的數據，2017年美國流感的住院死亡率是7.3%. -紅燒茄子-- ♂ (264 bytes) () 12/31/2021 postreply 17:56:44

• 這很難說。每個國家的醫療體係不同，收住院的標準差別很大 -fuz- ♂ (0 bytes) () 12/31/2021 postreply 18:09:19

• 流感相對容易被人忽視，到住院已經相當嚴重了。如果都像對待新冠一樣可能會減少部分死亡。 -阿明.- ♀ (0 bytes) () 12/31/2021 postreply 18:36:55

• 同一個醫療體係，南非每年流感的住院死亡率是25%（CDC數據），由此可比較出Omicron和流感的致死率。。 -紅燒茄子-- ♂ (1682 bytes) () 12/31/2021 postreply 20:09:35

• 要是其它國家也像南非這樣，那就全麵開放好了，管它陰陽，該幹嘛幹嘛。 -fuz- ♂ (0 bytes) () 12/31/2021 postreply 21:26:49

• 你這個數據截止在12月15日，從下麵截止到12月31日的死亡率圖形看： -阿明.- ♀ (185 bytes) () 12/31/2021 postreply 17:56:36

• 從圖形看，南非的omicron疫情死亡率比加拿大Delta疫情的死亡率還高（死亡率與感染統計無關）。 -阿明.- ♀ (0 bytes) () 12/31/2021 postreply 18:04:12

• 你這個圖用的是人口死亡率，這個才是合理的比較。主要問題是一家醫院的數據不一定有代表性，年輕人太多。 -solo1- ♂ (0 bytes) () 12/31/2021 postreply 18:28:03

• 尤其是現在感染率已經嚴重偏離實際了，隻能看死亡率，雖然也不會完全真實，但會好很多。 -阿明.- ♀ (0 bytes) () 12/31/2021 postreply 18:30:46
