Comparative Study
Attitudes to malaria, traditional practices and bednets (mosquito nets) as vector control measures: a comparative study in five west African countries.
Five West African communities were visited to assess the knowledge of the cause of malaria and to document traditional ways of treating and preventing the infection. Knowledge of the cause of malaria was low in the five communities visited. ⋯ Malaria was treated by a number of traditional practices, including herbal remedies. Bednets were used to a varying extent, from 44% Ghana to 86% Gambia, in each community to protect against mosquito bites but also for other purposes such as privacy, decoration and protection from roof debris dropping on the bed.

In 914 consecutive medical admissions to Komfo Anokye Teaching Hospital, the prevalence of infection with Human Immunodeficiency Virus type I (HIV-I) and Human Immunodeficiency Virus type 2 (HIV-2) was 12.6%. The prevalence in females was twice that found in males. The infection rate was maximum in the age group 25-29 years for females (45%) and 30-34 years for males (29%). ⋯ The cases with HIV-2 infection tended to be older than those with HIV-I infection. For detecting HIV seropositivity in our patients the World Health Organization recommended case definition for AIDS in Africa gave a sensitivity of 32%, a specificity of 93% and a positive predictive value of 42%. The case definition gave the highest specificity and positive predictive values when cases of tuberculosis were not included in the analysis.

With an increase in travel to tropical countries, the need to improve the disease-risk perceptions of travelers who are either naive or given inappropriate or ineffective advice is becoming increasingly important. More widely available, specialized centers that can provide advice on tropical or travel-related diseases have been established, but their efficacy on travelers' knowledge and health has not been verified. Therefore, this study was undertaken to evaluate the impact of the service provided by a routine travel consultation at the Hospital for Tropical Diseases Travel Clinic, London, England. ⋯ Our results show that a face-to-face interview for an average of 18 minutes by trained staff is an effective way of improving travelers' knowledge on certain topics. The slight improvements overall are explained by the levels of experience of travel and previously acquired knowledge of the clients in our study. Effective advice on malaria prevention and some health risks is given during an average consultation; however, there is still a need for improvement in giving information on the management of diarrhea, fever, and other travel diseases.
