RESUMO
This study was designed to document individuals’ adherence to annual ivermectin treatment and people’s willingness to continue taking ivermectin as an important predictor of sustained compliance with long-term ivermectin treatment. The study which was conducted between April and September, 2011 adopted a cross-sectional approach in collecting quantitative and qualitative data from the two Local Government Areas of Abia State that were assessed by REMO as hyper-endemic for onchocerciasis. The study population involved both high and low compliers groups. A Structured questionnaire was administered to 558 people to ascertain their compliance rate to annual and long-term ivermectin treatment and their willingness to sustain the treatment. Of these, 195 (34.9%) were males while 363 (65.1%) were females. Among these groups, 53.8% and 57.3% of males and females respectively were treated before. Of the 195 males and 363 females, only 25 (12.8%) males and 45 (12.4%) females were high compliers. On their willingness to continue with the drug, 483 (86.6%) claimed that most people take the drug, 495 (88.7%) affirmed that most people will continue with the drug while 555 (99.5%) indicated that they are personally willing to continue with the drug if made available. This is confirmed by the Chi-square (χ2) analysis at 0.05 level of significance that people are personally willing to continue with the drug if available (χ2 cal =163.585, P-value < 0.0001). Suggestions on ways to improve compliance to annual and long-term ivermectin treatment showed that health education/enlightenment ranked very high (78.3%). This is followed by “awareness through church/school” (77.5%). It is imperative that the existing health education materials be reviewed by taking into cognizance such factors that will improve individual’s willingness to comply with annual and long-term ivermectin treatment. Such materials should emphasize compliance among youths and children 5 years and above.
RESUMO
A study to ascertain the parasites associated with sachet drinking water, (popularly called "Pure Water" in Nigeria), in Awka, capital of Anambra State, southeast Nigeria was conducted. This was in order to determine the safety and suitability of such water for human consumption. Sachet water is a major source of drinking water for low and middle class Nigerians. The increase in demand of this water has led to the proliferation of industries in this sector, because of the economic benefits derivable from the sale. Samples of differently packaged sachet drinking water were purchased from producers, distributors, marketers and hawkers. Samples were observed macroscopically and pH tested. Using a sterile syringe, 10mls of water was taken from each sample and centrifuged at 2,500rpm per minute. Sediments observed were placed on a glass slide and observed microscopically using x10 and x40 objective lens for a possible parasite ova or cyst. The surface of each sachet of the packaged drinking water was also washed thoroughly and the resulting water was centrifuged and observed microscopically. All the tested water samples met the W.H.O. recommended standard, of being colorless, tasteless, odourless with average pH of 6.93. No parasites were found in the water in the sachets but some parasites were found on the surfaces of the sachets. The surface of the sachets of the packaged water purchased from hawkers had the highest number of parasites {15 (41.7%)}. Identified parasites include cysts of Ascaris lumbricoides (5.6%), Entamoeba histolytica (4.6%), hookworm (2.8), Trichuris trichuria (2.8%) and Giardia lamblia cysts (1.9%). Hawkers possibly play a very significant role (Ï2 = 20.21, df =2, p<0.05) in the transmission of parasitic infection from the outside of the sachets through improper handling. It is advocated among others that cleaning and washing of sachets of packaged drinking water before use will aid in breaking the transmission circle
