Trichinosis Human Transmission Data
a  Investigated period 19912000. For some
countries, there is no information for all years
of the investigated period. In this case, the
total number of human infections refers to the
number of investigated years. The average
includes clinical infections and infections
detected by serology, unless otherwise indicated.
b  Trichinella species of larvae from human
biopsies or from infected meat which was the
source of infection for humans. c  The average
infections refers to clinical cases only. d  The
average infections refers to hospitalized
individuals only. e  The official reports
underestimate the prevalence of human
trichinellosis at least for a coefficient of 10,
as suggested by seroepidemiological
investigations.

Societal events Population growth and migration
economic impoverishment war or civil conflict
lack of education sanitation Environmental
changes Changes in water ecosystems
deforestation flood/drought global
warming Public health infrastructure Curtailment
or reduction in prevention programs inadequate
communicable disease surveillance lacked of
trained personnel drug availability,
