This may be explained by our finding of a high rate of
subclinical infection by TMAdV in asymptomatic titi monkeys (35 %), but may also be due to separate introductions of TMAdV into the colony from an as - yet unidentified reservoir.
Determining the true burden of typhoidal Salmonellae
infections is hindered
by lack of population - based studies and adequate laboratory diagnostics.The Strategic Typhoid alliance across Africa and Asia study takes a systematic approach to measuring the age - stratified burden of clinical and
subclinical disease caused
by typhoidal Salmonellae
infections at three high - incidence urban sites in Africa and Asia.
