A Surprise Inoculation Against Cholera

After the cholera epidemic tore through Migori County in January–February 2015, Ministry of Public Health officials discovered a surprise— two communities in Rongo subcounty, the epicenter of the epidemic, experienced zero cases of cholera. Why did these two villages, Kauma and Kanyangiela, not present any cholera cases, and why were they seen as safe havens amidst a strong outbreak despite being initially considered areas of high risk? The Ministry of Health (MOH) sent a team of investigators to examine the situation.
