It starts with a fever. That's the most common symptom among people who get the coronavirus that's sweeping the world.
一開始會發燒。這是全球感染冠狀病毒的人們中最常見的症狀

Here's how symptoms typically progress among patients:
患者通常會出現以下症狀：

Day 1: Patients run a fever. They may also experience fatigue, muscle pain, and a dry cough. A small minority may have had diarrhea or nausea one or two days before.
第一天：患者發燒。他們可能還會感到疲勞，肌肉疼痛和乾咳。一小部分人可能在一兩天前腹瀉或噁心。
(乾咳是警訊)

Day 5: Patients may have difficulty breathing, especially if they are older or have a preexisting health condition.
第5天：患者可能呼吸困難，尤其是年齡較大或已有健康狀況的患者。
(如果在台灣這時你應該去檢驗&就醫)

Day 7: This is how long it takes, on average, before patients are admitted to a hospital, the Wuhan University study found.
第七天：武漢大學的一項研究發現，平均來說，這是患者住院的平均時間。
(從這時起是分水嶺，不是復原就是惡化)

Day 10: If patients have worsening symptoms, this is the time in the disease's progression when they're most likely to be admitted to the ICU. These patients probably have more abdominal pain and appetite loss than patients with milder cases.
第10天：如果患者的症狀惡化，此時最有可能被ICU收治。 這些患者可能比輕度患者有更多的腹痛和食慾不振。

Only a small fraction die: The fatality rate has hovered at about 3%.
只有一小部分人死亡：死亡率保持在3％左右。
(假設醫療系統還能承受的狀態，這個比例依然很糟)

Day 17: On average, people who recover from the virus are discharged from the hospital after 2 1/2 weeks.
第17天：平均而言，從病毒中恢復的人在2 1/2週後會出院。
(復原期過長，2.5週消耗醫療資源)

The first symptoms, however, may not come right after a person has been infected. A recent study found that the virus' average incubation period is about five days.
最初的症狀可能不會在被感染後立即出現。最近的一項研究發現，病毒的平均潛伏期約為五天。
(無症狀有傳播力)

Once symptoms do appear, they can be similar to those of pneumonia. But Paras Lakhani, a radiologist at Thomas Jefferson University, told Business Insider that COVID-19 could be distinguished from pneumonia because of how it worsens over time.
一旦出現症狀，它們可能類似於肺炎。 但是Thomas Jefferson大學的放射學家說，COVID-19隨著時間的推移，可能會發展成不同於肺炎的症狀。

"Pneumonia usually doesn't rapidly progress," Lakhani said. "Typically, most hospitals will treat with antibiotics, and patients will stabilize and then start to get better."
“肺炎通常不會迅速進展。” “通常大多數醫院將使用抗生素治療，患者會穩定下來，然後開始好轉。”

People with COVID-19, however, can get worse even after they receive treatment such as fluids or steroids.
患有COVID-19的人即使接受液體或類固醇等治療，可能也會變得更糟。

我看到英國一個28歲案例，從無症狀突然變成呼吸困難。他說：“我從來沒有想像過，我會病的這麼嚴重"
