    Abstract

    Malaria remains a major occupational health concern that accounts for several deaths per year and numerous lost working days among the expatriate population, working or living in high malarious areas. Approximately 1% of all non-immune travellers who acquire P. falciparum infection die. Nigeria is a malaria endemic country with high transmission throughout the year. Employers within the oil and gas industry usually adopt a malaria control program which in generic terms consists of awareness, bite prevention, use of chemoprophylaxis and early diagnosis and treatment. It is clear that no single approach will sufficiently reduce this risk.

    This study broadly aims to determine the effectiveness or otherwise of malarial risk communication and minimisation programs of oil industry employers in Nigeria in order to be able to improve the system.

    Primary data was gathered through self-administered questionnaires to 35 non-immune respondents. The study has shown that awareness to the malarial risk is high in the population at risk and this increased risk perception is significantly associated with risk-averse behaviours (χ2 = 6.13, CI approx 99%). However, engagement with the different methods of prevention is varied and effective methods like sleeping under Insecticide-Treated nets (ITNs) seem to be poorly employed (22%). Take-up of chemoprophylaxis (91%) while at work is encouraging, as is compliance post-travel. Malarone® is the most used chemoprophylactic agent. Willingness to continue to take chemoprophylaxis while working in a malarious location (84%) justifies the increased risk perception. Two-thirds (60%) of the respondents that use chemoprophylaxis also carry CMKs further strengthening finding of respondents‟ increased risk awareness to malaria. However, this risk perception did not seem to be significantly associated with acceptance of employers‟ policy contractually obligating use of chemoprophylaxis. (χ2 =0.73, CI approx 50%) In deciding to give advice concerning use of any drug, the risk-benefit ratio must always justify the final decision.
