Document Summary
Infectious disease is the result of a failure in adaptation. The serious or fatal diseases are those in which the microbe and host have not yet adapted to ea(cid:272)h other; ea(cid:272)h (cid:862)struggles(cid:863) (cid:449)ith the other. Conversely, the normal flora microbes and their hosts are well-adapted to each other and have evolved to peacefully coexist. Epidemics and pandemics have sporadically wiped out populations and influenced the course of civilization. The influenza pandemic of 1918 killed 50 to 100 million people worldwide in a single year: biology of influenza. Influenza symptoms are cold-like, with headache, high fever, muscle pain, severe cough, and congestion. Infects humans and other species, including seals, dogs, pigs, and birds (particularly ducks) Fomites play a secondary role: conditions of cooler temperatures and low humidity favor transmission, crowding, close intermingling favors transmission.
