<p>142 confirmed cases and 3,844 contacts were identified between September 20 and January 11 2023. Overall, 33% of confirmed cases were listed as contacts before their identification as cases. Residing in urban areas had three times the odds (OR=3.0 (95% CI:1.1-8.27, p=0.031) of being listed as a case prior to the onset of symptoms compared to their rural counterparts. Cases previously identified as contacts had fewer median days from onset to isolation (4 versus 6; p&lt;0.007) and confirmation (4 versus 7; p&lt;0.0001). Cases that were previously listed as cases had a 66% (IRR=0.34, 95% CI:0.16-0.69, p=0.003) less rate of infecting another person compared to those who were not previously listed as contacts prior to their illness.</p>
