Written in mid-2020 and first published in July 2020, this research-style article surveys the international impact of the Covid-19 pandemic rather than the biology of the virus. After a brief list of historical pandemics from the Antonine Plague to HIV/AIDS, it tabulates the fast policy responses of governments in four groups, monetary, fiscal, public-health and human-control measures, with the countries that adopted each. Two positive factors are highlighted: the internet, which allowed open sharing of Covid research at unprecedented speed, and cross-border cooperation in supplying test kits, reagents, ventilators and masks.
The economic sections draw on World Bank, IMF and WTO figures: 40 to 60 million people pushed into extreme poverty, global poverty rising from 8.2% to 8.6% in 2020, projected contractions of advanced and developing economies, fiscal packages and central-bank spending by country, and optimistic versus pessimistic WTO trade scenarios for 2020–21, alongside the strain on child health and on girls' education. The article then reviews the drugs under emergency authorisation and the 145 vaccines then in development, warns about contact-tracing apps such as Aarogya Setu that are neither open-source nor covered by privacy law, notes Hungary's rule by decree, and describes the WHO-backed Covid-19 Technology Access Pool. It concludes that the pandemic has reminded humanity that science, not superstition, and human solidarity are what keep us safe, and closes with fourteen references.
