A malaria outbreak following a British military deployment to Sierra Leone

J Infect. 2003 Oct;47(3):225-30. doi: 10.1016/s0163-4453(03)00063-x.


Objectives: To describe a malarial outbreak amongst a British military force deployed to Sierra Leone in May 2000.

Methods: A case-control study was conducted that investigated possible risk or protective factors affecting the population.

Results: All bite avoidance measures (use of insecticide-treated bed nets and insecticide-treated clothes and use of thermal fogging/knockdown insecticide sprays) offered some degree of protection, although only use of clothes and nets was significant at the 5% level. Use of 3 or 4 protection measures was significantly protective, as was the cumulative protective effect when using multiple protective measures.

Conclusion: Professionals giving travel advice must continue to advice travellers that they can significantly improve their levels of malarial protection by using multiple protection measures.
