RESUMEN
Community event-based surveillance aims to enhance the early detection of emerging public health threats and thus build health security. The Ministry of Health of Vietnam launched a community event-based surveillance pilot program in 6 provinces to improve the early warning functions of the existing surveillance system. An evaluation of the pilot program took place in 2017 and 2018. Data from this evaluation were analyzed to determine which factors were associated with increased detection and reporting. Results show that a number of small, local events were detected and reported through community event-based surveillance, supporting the notion that it would also facilitate the rapid detection and reporting of potentially larger events or outbreaks. The study showed the value of supportive supervision and monitoring to sustain community health worker reporting and the importance of conducting evaluations for community event-based surveillance programs to identify barriers to effective implementation.

Infection by the larval form of Oestrus ovis (sheep bot fly) is common in many areas of Peru. This is an obligate parasite of sheep and goats, and it is the cause of oestrosis, or nasal myiasis, which can lead to severe clinical manifestations in livestock. A case of myiasis caused by O. ovis in a llama (Lama glama) in Cuzco, Peru, is reported here. This llama presented with respiratory distress and died due to bilateral hemorrhagic pneumonia. During the necropsy, six intact dipterous larvae were recovered from the nasal fossae and cranial sinuses being identified as O. ovis. This is the first report of nasal myiasis in llamas due to O. ovis in Peru.
Infecção pela forma larval de Oestrus ovis (bicho da cabeça) é comum em muitas regiões do Peru. Este é um parasito obrigatório de ovinos e caprinos, e é a causa de oestrose ou miíase nasal, que pode conduzir à manifestações clínicas graves nos animais. Relatou-se um caso de miíase causada por O. ovis numa lhama (Lama glama) em Cuzco, Peru. A lhama apresentou insuficiência respiratória e morreu de pneumonia bilateral hemorrágica. Durante a necropsia, seis larvas intactas do díptero foram recuperadas das fossas nasais e dos seios cranianos e identificadas como O. ovis. Este é o primeiro relato de miíase nasal em lhamas por O. ovis no Peru.
