  • The first world war was among the deadliest conflicts in history and killed more than 20 million people.


  • But an outbreak of flu that began as the war ended, turned out to be far more destructive.


  • It was known as the Spanish Influenza, and infected one in three humans on earth.


  • It was the worst pandemic in modern history and claimed the lives of between 50 and 100 million people.


  • Now, as a new strain of coronavirus spreads across the world, when does a disease become a pandemic and if it does, what happens next?


  • Disease experts use the term "pandemic" when a new infection spreads to multiple countries and continents at the same time, affecting many people.

    疾病學家以 pandemic (全球大流行) 一詞來描述在同時數國、州際間流傳,且感染許多人的疾病。

  • That's different from another term, epidemic, which describes an infection outbreak that's larger than usual, but stays confined to a single location or region.

    這與另一個詞彙 epidemic (流行傳染病) 不同,此詞是指一個範圍性的爆發,但範圍維持在一個地點或地區。

  • So when does a disease officially become a pandemic?


  • The World Health Organization is the body that decides when an infectious disease formally becomes a pandemic, but that choice is not always black and white.


  • The group's director-general says the WHO assesses whether to use the word "pandemic" by evaluating three things.

    該組織的幹事長說,世衛組織用三個準則來評定是否使用 pandemic 一詞。

  • First is the geographical spread of the virus.


  • Second is the severity of the disease caused by the virus and lastly, the societal impact of the disease.


  • A disease is more likely to become a pandemic if it is caused by a new strain of a virus, as is the case with Coronavirus Disease 2019 or COVID-19.

    若為新型病毒則較容易成為全球大流行,如這次的新冠肺炎 (新冠病毒)。

  • The ease with which it infects people and spreads from person to person also play a role in the designation.


  • Past pandemic outbreaks have typically originated from animal viruses, before crossing over to humans.


  • These can spread rapidly around the world because people do not have the immunity needed to fight the new infection.


  • COVID-19 was declared a pandemic in March 2020, the sixth pandemic declared in about a century.

    新冠病毒在 2020 年 3 月被確認為全球大流行,是一百年來第六個大流行疾病。

  • The 1918 Spanish flu was easily the deadliest flu pandemic of the 20th century, killing tens of millions of people.

    1918 年的西班牙流感是 20 世紀裡最致命的疾病,殺死了上千萬的人。

  • The Asian flu outbreak followed in 1957, killing roughly 1.1 million people around the world.

    1957 年爆發的亞洲流感則在全球帶走了約 110 萬人。

  • Thankfully scientists were able to develop a vaccine quickly, effectively containing its spread.


  • Another influenza outbreak, the Hong Kong flu, started to spread from China in 1968.

    另一次則是香港流感,1968 年時從中國開始散播。

  • It was caused by a compound virus, which combined the Asian virus from ten years earlier with a form of bird flu.


  • It killed around one million peoplemost of them older than 65.

    這次流感殺死了約一百萬人,大多數人為超過 65 歲的長者。

  • HIV, which was first identified as the virus behind AIDS in 1983, was also considered a pandemic.

    HIV 病毒,在 1983 年被確認為是愛滋病源頭的病圖,也曾被宣布為大流行。

  • The human immunodeficiency virus severely damages the cells in your immune system and weakens your ability to fight everyday infections and disease.


  • In the past 40 years, it's killed 35 million people worldwide, about half of the people who were infected by the virus.

    過去 40 年來,HIV 病毒在全世界害死了 3,500 萬人,近乎所有感染者的一半。

  • Then in 2009, a new outbreak, initially called the swine flu, was named a pandemic.

    2009 年時,又發生疾病爆發,一開始被稱為豬瘟,後來也被確定為大流行。

  • It infected nearly 61 million people, and experts estimate it killed up to 575,000 people in a single year.

    該疾病感染了近乎 6,100 萬人,專家估計一年之中最多有 57.5 萬人死於該疾病。

  • The WHO declared the pandemic over in August 2010, but the virus has continued to circulate as a seasonal flu ever since.

    世衛組織在 2010 年 8 月宣布豬瘟為大流行,該病毒自那時起成為季節性流感不斷侵擾人類。

  • In recent years, the WHO has changed how it decides whether an outbreak constitutes a pandemic, following criticism that the threat of the 2009 swine flu had been exaggerated.

    近年來,世衛組織對於決定一個疾病是否為大流行的流程有了變化,因有批評指出 2009 年時豬瘟事件被過度放大。

  • Many governments stockpiled vaccines which ultimately went unused, while pharmaceutical companies profiteered from the ensuing panic.


  • The disease turned out to be milder than was originally thought.


  • Since then, the WHO has released a guide to manage flu pandemics at a national and international level.


  • According to its pandemic preparedness plan, national governments are required to follow specific protocolsif a pandemic is declaredto prevent or reduce the spread of a virus.


  • For instance, authorities at a regional and local level must fully mobilize health systems, hospitals and medical workers.


  • In addition, healthcare providers must plan for a surge in patients, and offer protective equipment to their workforce.


  • Governments must also limit social interaction, initiate quarantine measures and enforce isolation procedures.


  • Upgrading a disease to a pandemic outbreak also has psychological implications for how we think about a disaster.


  • According to the WHO "using the word pandemic carelessly has no tangible benefit, but it does have significant risk in terms of amplifying unnecessary and unjustified fear and stigma."


  • Six months before the latest coronavirus outbreak, a WHO report noted that "many countries still lack a national pandemic influenza preparedness plan."


  • So what are the economic costs of a pandemic?


  • A previous coronavirus strain called SARS, which was detected in 2002, wasn't widespread enough to become a pandemic.

    上一種侵襲人類的冠狀病毒為 SARS,在 2002 年時被發現,但並沒有成為大流行。

  • While it only infected more than 8,000 people, it still cost the global economy more than 50 billion USD in 2003.

    SARS 僅僅感染了 8,000 餘人,但它還是在 2003 年造成了全球超過 500 億美元的經濟損失。

  • You see, advances in medicine, communication and technology have brought mortality rates down.


  • But greater trade flows and cheaper air travel have seen the world economy become ever more interconnected and that causes the costs of a pandemic to rise.


  • A report now estimates that a pandemic will cost 570 billion USD a year.

    一份報告估計,大流行疾病將造成全球一年 5,700 億美元的損失。

  • That represents 0.7 percent of the world's total income.

    這代表全世界 0.7% 的收入。

  • A pandemic can overwhelm global health systems.


  • It can also force infected individuals to avoid the office or work less productively.


  • The fear of infection spread forces people to stay apart.


  • And that can be even more debilitatingshutting down schools, businesses and public services.


  • Insurance companies must also watch developments closely.


  • A pandemic can mean more travel claims, more hospital claims and choke up global supply chains.


  • The impact on corporate earnings can then cascade into financial markets all around the world.
