Weekly EPIEpidemiological Watch bulletin OVERALL SITUATION Adverse climatic conditions shifting from severe drought to heavy Deyr rains (October-December, 2019) causing floods, continued across Somalia. This coupled with other drivers of humanitarian crisis, such as armed conflict and evictions have led to 643 000 internal displaced persons in 28 drought-affected districts. Shortage of safe water, and poor hygiene and sanitation have left communities in drought-affected districts and IDP camps vulnerable to infectious disease outbreaks such as measles and diarrhoea.
