Pandemic Preparedness and Global Cooperation

International cooperation on pandemic preparedness is governed principally by the International Health Regulations (IHR), a legally binding agreement among WHO member states first adopted in a narrower form in 1969 and substantially revised and expanded in 2005 following the 2002–2003 SARS outbreak, which exposed significant gaps in the earlier framework's scope and enforcement. The revised 2005 IHR obligate the 196 states party to it (all WHO member states, plus a small number of additional parties) to develop core surveillance and response capacities, to report events that may constitute a Public Health Emergency of International Concern (PHEIC) to the WHO, and to refrain from imposing trade or travel restrictions beyond what the evidence justifies — a provision that COVID-19 tested severely, since dozens of countries imposed unilateral travel bans and export restrictions on medical supplies during 2020 despite the IHR's explicit discouragement of such measures, illustrating a persistent gap between the regulations' legal obligations and states' actual behavior during a real crisis.
