Evaluation of rodent control to fight Lassa fever based on field data and mathematical modelling

This resource aims to to assess the efficacy of rodent control by performing a 4-year field experiment in rural Upper Guinea, and developing a mathematical model to simulate different control strategies (annual density control, continuous density control, and rodent vaccination).

Rodent control to fight Lassa fever: Evaluation and lessons learned from a 4-year study in Upper Guinea

This paper performed a 4 year intervention based on chemical rodent control, utilizing anticoagulant rodenticides in 3 villages and evaluating the rodent abundance before and after treatment. They found that chemical treatment provides an effective tool to control local rodent populations. Based on these findings and the acceptability of rodent control activities at community level, the authors aim to promote, in coordination with health and agricultural authorities, a more holistic approach, including rodent trapping and poisoning, environmental hygiene, personal hygiene, house repairs and rodent-proof storage.

Hunting of peridomestic rodents and consumption of their meat as possible risk factors for rodent-to-human transmission of Lassa virus in the Republic of Guinea

This study comparing two regions in Guinea, Pita and Gueckedou, observed three major risks for Lassa virus transmission: rodent infestation, uncovered food and hunting of peridomestic rodents as protein source. Hunting and preparation of rodents was identify as a specific risk, however more research is needed to ascertain the age and sex-specific risk factors, sociocultural and economical leading to rodent consumption.
