It is important for HCWs to remember that over 20 pathogens have been reportedly transmitted from needle stick injuries. The most serious are the transmission of Hepatitis C virus, Hepatitis B virus and Human immunodeficiency virus. World Health organization report showed that 16,000 HCV, 66,000 HBV & 1000 HIV may have occurred worldwide. Two million needle stick injuries are reported in health care providers every year. This study was institution based cross-sectional study conducted in 10 Bahir Dar City public health centres from June to October 2014. 194 health care workers were selected using cluster followed by systematic random sampling technique. Data has been collected using pre tested self-administered questionnaire. The collected data was entered and analyzed by using SPSS statistical software version 20. Bi-variate logistic regression model was used to assess the association between dependent and independent variables and P-value less than 0.05 was considered statistically significant.Among 194 study participants, 83 (42.8%) participants showed history of needle stick injuries. Needle stick injuries were higher in outpatient departments and emergency unit, 59 (30%) and delivery room 40 (20.6%). The proportion of needle stick injuries were higher among health officers 16/30 (53.3%). The major item cause for needle stick injuries were syringe with needle, 55/83 (66%) and the most injured body part were fingers 58/83 (70.7%). In conclusion, significant proportion of health care workers experienced needle sticks injuries. Therefore, ongoing training and supervision should be given to curb the situation in the study area.

Background: Human subcutaneous myiasis is an endemic, understudied disease in Ethiopia. Objective: The aim of this study was to assess knowledge, perceptions and practices in different urban and rural communities of Jimma Zone, southwestern Ethiopia, related to human myiasis. Method: A cross-sectional, descriptive, comparative study was carried out during March-June 2005 in 5 urban and 3 rural kebeles in Jimma Zone. Kebeles were chosen by random sampling and a total of 1,272 households were selected by systematic random sampling technique for interview. Results: Most subjects (60.0%) mentioned lying on damp soil as the cause of myiasis. More urban than rural communities who wore un-ironed clothes had myiais infestation (p< 0.05). Myiasis was reported to be common in the lower extremities (65.6%), upper extremities (56.7%), abdomen (48.9%) and back (34.9%). A total of 86% dwellers responded that myiasis was more common during the wet season. More than half of the interviewees were knowledgeable about the clinical presentation of the disease. The most common signs and symptoms were itching (94.0%), pus discharge (82.9 %) and papules (79.5%). The majority (87.9%) of the study subjects treated infestations with hot matches. Wearing dry clothes (38.6%) was reported to be effective preventive measure. Nearly 64.8% of the rural and 68.7% of the urban communities knew that human subcutaneous myiasis is preventable. Conclusion: Due to the low levels of knowledge about myiasis, we recommend that community health education programs be developed through the health services to raise the awareness levels about this infestation to the general population.
