a mi esto me recuerda mucho a lo que ha pasado en wuhan y lo que esta pasando en otras ciudades chinas.
The Story of Influenza - The Threat of Pandemic Influenza - NCBI Bookshelf
The best data on this comes from the U.S. Army. Of the Army's 20 largest cantonments, in the first five affected, roughly 20 percent of all soldiers with influenza developed pneumonia. Of those, 37.3 percent died (Soper, 1918; undated draft report).
In the last five camps affected—on average 3 weeks later—only 7.1 percent of influenza victims developed pneumonia. Only 17.8 percent of the soldiers who developed pneumonia died (Soper, 1918).
Inside each camp the same trend held true. Soldiers struck down early died at much higher rates than soldiers in the same camp struck down late.
Similarly, the first cities struck—Boston, Baltimore, Pittsburgh, Philadelphia, Louisville, New York, New Orleans, and smaller cities hit at the same time—all suffered grievously. But in those same places, the people struck by influenza later in the epidemic were not becoming as ill, and were not dying at the same rate, as those struck in the first 2 to 3 weeks.
Cities struck later in the epidemic also usually had lower mortality rates. One of the most careful epidemiologic studies of the epidemic was conducted in Connecticut. The investigator noted that “one factor that appeared to affect the mortality rate was proximity in time to the original outbreak at New London, the point at which the disease was first introduced into Connecticut…. The bichito was most virulent or most readily communicable when it first reached the state, and thereafter became generally attenuated” (Thompson and Thompson, 1934a: 215).
The same pattern held true throughout the country and the world. It was not a rigid predictor. The bichito was never completely consistent. But places hit later tended to suffer less.
