Eight times as many flu cases were reported among UK horses in the first six weeks of 2019 as in the whole of 2018, and there was particular concern about its appearance in vaccinated horses and thoroughbreds. [33] The outbreak continued at an elevated rate for the first half of the year and a peak in cases was seen at the end of June.
The first horses to return to the main continent were 16 specifically identified [clarification needed] horses brought by Hernán Cortés. Subsequent explorers, such as Coronado and De Soto , brought ever-larger numbers, some from Spain and others from breeding establishments set up by the Spanish in the Caribbean.
Mortality rates were not appreciably above normal; [2] in the United States ~75,000 flu-related deaths were reported in the first six months of 1918, compared to ~63,000 deaths during the same time period in 1915. [99] In Madrid, Spain, fewer than 1,000 people died from influenza between May and June 1918. [100]
The disease was rare at the beginning of the century, and worldwide there were only a few thousand cases per year, but by the 1950s there were 60,000 cases each year in the US alone [160] and an average of 2,300 in England and Wales. [161]
Since the late 1800s, pandemic outbreaks of novel influenza strains have occurred every 10 to 50 years. Five flu pandemics have occurred since 1900: the Spanish flu from 1918 to 1920, which was the most severe; the Asian flu in 1957; the Hong Kong flu in 1968; the Russian flu in 1977; and the swine flu pandemic in 2009.
Around 4,200 years ago, one particular lineage of horse quickly became dominant across Eurasia, suggesting that’s when humans started to spread domesticated horses around the world, according to ...
The difference between the influenza mortality age-distributions of the 1918 epidemic and normal epidemics. Deaths per 100,000 persons in each age group, United States, for the interpandemic years 1911–1917 (dashed line) and the pandemic year 1918 (solid line). [61] The Spanish flu pandemic lasted from 1918 to 1920. [62]
Viruses that are shed for long periods of time after a horse gets better are much harder to control. Horses tend to be most infectious (i.e. shedding the most virus) in the first 24–48 hours after they develop a fever, but they can shed the virus for up to 7–10 days after their signs of illness disappear.
