Abstract
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.
