Impact of Single Dose Praziquantel Treatment on Schistosoma haematobium Infection among School Children in an Endemic Nigerian Community

Schistosomiasis is prevalent in Nigeria, and the foremost pathogen is Schistosoma haematobium, which affects about 29 million people. Single dose of the drug praziquantel is often recommended for treatment but the efficacy has not been documented in certain regions. Therefore, this study was designed to assess the impact of single dose praziquantel treatment on S. haematobium infection among school children in an endemic community of South-Western Nigeria. Urine samples were collected from 434 school children and 10 ml was filtered through Nucleopore filter paper before examination for egg outputs by microscopy. The prevalence was 24.9% at pre-treatment. There was no statistically significant difference for the prevalence of infection between males (14.7%) and females (10.2%), although the mean egg count for the females (9.87) was significantly more (P < 0.05) than the males (6.06). At 6 and 12 months post-treatment there was 74.4% and 86.4% reduction in the mean egg count, respectively. Interestingly, an increased prevalence of infection from 2.1% at 6 months to 7.7% at 12 months post-treatment was observed, nonetheless the mean egg count was reduced to 0.27 at 12th month from 1.98 at 6 months post-treatment. Resurgence in the prevalence rate between 6 and 12 months post-treatment with praziquantel is herein reported and the need for a follow-up treatment in endemic areas for adequate impact on schistosomiasis control is discussed.

Perception and affordability of long-lasting insecticide-treated nets among pregnant women and mothers of children under five years in Ogun State, Nigeria

Despite the distribution of long-lasting insecticide-treated nets [LLINs] in Nigeria, access to and use of LLINs continues to be minimal. Little is also known about the perceived fair price people are willing to pay for LLINs in Ogun State, South-West Nigeria. Data were collected using semi-structured questionnaire among pregnant women attending antenatal clinics and mothers of under-five children in randomly-selected malaria holo-endemic communities of Ijebu North and Yewa North local government areas of Ogun State. Results showed that only 23.6% of 495 respondents owned and were using LLINs. One of the main reasons for non-use of LLINs was unaffordability of LLIN cost. 84.2% of the 495 respondents were willing to pay at a hypothetical price of N800.00 [US$5.00] for a LLIN, 15.6% were unwilling and 0.2% was indifferent to buying it at the price. Their willingness to pay was significantly determined by education and occupation [p = 0.00]. Health education strategies need to be developed to increase awareness and demand for LLINs. However, there is the need to take into account preferred access outlets and the diversity in willingness to pay for LLINs if equity to access is to be ensured in the study communities
