1557 influenza pandemic

In 1557, a pandemic strain of influenza emerged in Asia, then spread to Africa, Europe, and eventually the Americas. This flu was highly infectious and presented with intense, occasionally lethal symptoms. Medical historians like Thomas Short, Lazare Rivière and Charles Creighton gathered descriptions of catarrhal fevers recognized as influenza by modern physicians attacking populations with the greatest intensity between 1557 and 1559. The 1557 flu saw governments, for possibly the first time, inviting physicians to instill bureaucratic organization into epidemic responses. It is also the first pandemic where influenza is pathologically linked to miscarriages, given its first English names, and is reliably recorded as having spread globally. Influenza caused higher burial rates, near-universal infection, and economic turmoil as it returned in repeated waves.
