收集全球健康數據是一個不完美的科學過程：工作者們走訪民宅敲門詢問，將回答記錄在紙質表單上，然後輸入數據——基於這些漏洞百出的資訊，那些國家作出重大決策。數據專家 Joel Selanikio 談論了過去幾十年在健康醫療數據收集方面所獲得的巨大改變——從開始使用掌上電腦到 Hotmail，到現在使用雲端技術。


意外的醫療保健大數據革新的開端

For decades, global health relied on paper forms and manual data entry, leaving critical questions about disease, medicine, and even child mortality largely unanswered. In many countries, knowing how many children have been vaccinated requires months or years of door-to-door surveys, with stacks of forms often never processed. By harnessing cloud technology and simple mobile phones, data collection now happens in real time, empowering health workers to make informed decisions instantly. This shift shrinks timelines from years to minutes, turning scattered guesses into actionable knowledge.
