Public health strategies include diagnosis and treatment, but
there are significant obstacles to successful STD management.
Only a small fraction of STD-infected people in developing
countries are cured, for reasons indicated on this slide. The
bars show a conceptual model for inadequate cure; the model
is not based on numerical data.
Reading left to right on this slide, one sees that a large
proportion of people with STDs have no symptoms. Those without
symptoms would not seek medical help. As shown in the second
bar, only some of those with symptoms seek treatment or have
access to diagnostic or treatment services. Moreover, only a
proportion of those seeking treatment receive a correct diagnosis.
Among those correctly diagnosed, only some receive correct treatment
or complete their treatment regimen. Among those who receive
correct and complete treatment, only a proportion are cured.
Finally, only some of STD-infected people who are cured will
refer their partners for treatment, avoiding risk of reinfection.
