From the Field: WHO Cholera Response

During my WHO assignment in Bayelsa State, I contributed to disease surveillance and outbreak-response activities during the cholera response. WHO Nigeria's official EPR Snapshot Bulletin documents response activities in Bayelsa, including active case search in Famgbe and AVoC-SURGE engagement with state leadership. Field photographs I captured during the response were selected for publication in the bulletin and credited by WHO.
