“…The bacterial DNA detection rate by PCR of nasal swabs (4.6%) among contacts agrees with those reported for other hyperendemic regions, which were 5.9% (Beyene et al, 2003) and 4.0% (Job et al, 2008), and endemic areas, which was 4.7% (Araújo et al, 2012). The PCR detection rate using oral swabs obtained in the present study was similar to previously reported values.…”
