Possibly the first influenza epidemic occurred around 6,000 BC in China, and possible descriptions of influenza exist in Greek writings from the 5th century BC. In both 1173–1174 AD and 1387 AD, epidemics occurred across Europe that were named "influenza". Whether these epidemics and others were caused by influenza is unclear since there was no consistent naming pattern for epidemic respiratory diseases at that time, and "influenza" didnt become completely attached to respiratory disease until centuries later. Influenza may have been brought to the Americas as early as 1493, when an epidemic disease resembling influenza killed most of the population of the Antilles.The first convincing record of an influenza pandemic was chronicled in 1510; it began in East Asia before spreading to North Africa and then Europe. Following the pandemic, seasonal influenza occurred, with subsequent pandemics in 1557 and 1580. The flu pandemic in 1557 was potentially the first time influenza was connected to miscarriage and death of pregnant women. The 1580 flu pandemic originated in Asia during summer, spread to Africa, then Europe, and finally America. By the end of the 16th century, influenza was likely beginning to become understood as a specific, recognizable disease with epidemic and endemic forms. In 1648, it was discovered that horses also experience influenza.Influenza data after 1700 is more informative, so it is easier to identify flu pandemics after this point, each of which incrementally increased understanding of influenza.
