Prevalence and Factors Associated with Group A Rotavirus Infection Among Children with Acute Diarrhea in Mwanza, Tanzania.

Rotavirus infections frequently cause acute gastroenteritis in humans and are the most important cause of severe dehydrating diarrhea in young children in both developed and developing countries. This was a prospective cross-sectional, hospital-based study on 300 children ≤ 5 years with acute watery diarrhea who attended Bugando Medical Centre (BMC) and Nyamagana District hospital between May and November 2009. Stool specimens were tested for rotavirus infection using latex agglutination test. Data were cleaned and analyzed using SPSS 11.0. Of 300 children with acute watery diarrhea, 136 (45.3%) were female and the mean age was 12.63 months (SD = 10.4). Sixty-two (20.7%) children were found to have rotavirus infection. Of children with severe malnutrition three (37.5%) were infected with rotavirus. Fifty-two (84%) of children with rotavirus infection were below two years of age. Severe dehydration was present in 48 (16%) children of whom 12 (25%) were infected with rotavirus compared to 18 (16.6%) of 109 children with no dehydration. Living next door to a child with diarrhea was highly associated with rotavirus infection (43% versus 19%; p = 0.036). The mean hospital stay among children with rotavirus infection was 3.66 days versus 2.5 days for those without rotavirus (p = 0.005). Rotavirus infection is prevalent in Mwanza region and contributes to prolonged hospital stay. Proper education on hygiene to control diarrheal diseases among children should be emphasized. Extensive studies to determine the serotypes of rotavirus are warranted in the region before rotavirus vaccine is introduced

Knowledge, attitudes and practices regarding malaria and mosquito net use among women seeking antenatal care in Iringa, south-western Tanzania

To improve control measures against malaria, Tanzania has increased the distribution of free and subsidized insecticide-treated mosquito nets (ITNs) to pregnant women. However, data on knowledge, attitudes and practices of these women regarding malaria are scarce. This study was carried out to describe knowledge, attitudes and practices towards malaria, mosquito net ownership and use among women seeking antenatal care at Iringa Regional Hospital in south-western Tanzania. The study involved women attending the antenatal clinic of the hospital. A pre-tested structured questionnaire was applied to collect information on socio-demographic characteristics, mosquito net ownership and use, as well as knowledge, attitudes and practices about malaria and its control. Among the 222 pregnant women included, 173 (78%, 95%CI, 72-84.2) owned a mosquito net, and 150 (68%, 95%CI, 61-75) reported to sleep always under a mosquito net. The use of mosquito nets was mentioned by 142 (64%, 95%CI, 56.2-72). Of the 46 women who did not own a mosquito net, seven (15.2%) reported cost as the main obstacle for owning one. About 53% (95%CI, 44-62) preferred to use mosquito nets they bought rather than the one provided for free. Several factors such as gravidity, fearing of getting malaria, knowledge on the cause, marital status, and ways used to prevent malaria were significantly associated with mosquito net ownership (all

Factors Influencing the Implementation of Integrated Management of Childhood Illness (IMCI) by Healthcare Workers at Public Health centers & Dispensaries in Mwanza, Tanzania.

\ud Integrated Management of Childhood Illness (IMCI) was developed by the World Health Organization (WHO) and the United Nations International Children's Fund (UNICEF) and aims at reducing childhood morbidity and mortality in resource-limited settings including Tanzania. It was introduced in 1996 and has been scaled up in all districts in the country. The purpose of this study was to identify factors influencing the implementation of IMCI in the health facilities in Mwanza, Tanzania since reports indicates that the guidelines are not full adhered to by the healthcare workers. A cross-sectional study design was used and a sample size of 95 healthcare workers drawn from health centers and dispensaries within Mwanza city were interviewed using self-administered questionnaires. Structured interview was also used to get views from the city IMCI focal person and the 2 facilitators. Data were analyzed using SPSS and presented using figures and tables. Only 51% of healthcare workers interviewed had been trained. 69% of trained Healthcare workers expressed understanding of the IMCI approach. Most of the respondents (77%) had a positive attitude that IMCI approach was a better approach in managing common childhood illnesses especially with the reality of resource constraint in the health facilities. The main challenges identified in the implementation of IMCI are low initial training coverage among health care workers, lack of essential drugs and supplies, lack of onsite mentoring and lack of refresher courses and regular supportive supervision. Supporting the healthcare workers through training, onsite mentoring, supportive supervision and strengthening the healthcare system through increasing access to essential medicines, vaccines, strengthening supply chain management, increasing healthcare financing, improving leadership & management were the major interventions that could assist in IMCI implementation. The healthcare workers can implement better IMCI through the collaboration of supervisors, IMCI focal person, Council Health Management Teams (CHMT) and other stakeholders interested in child health. However, significant barriers impede a sustainable IMCI implementation. Recommendations have been made related to supportive supervision and HealthCare system strengthening among others.\u

Predictors of positive blood culture and deaths among neonates with suspected neonatal sepsis in a tertiary hospital, Mwanza- Tanzania

Neonatal sepsis is a significant cause of morbidity and mortality in neonates. Appropriate clinical diagnosis and empirical treatment in a given setting is crucial as pathogens of bacterial sepsis and antibiotic sensitivity pattern can considerably vary in different settings. This study was conducted at Bugando Medical Centre (BMC), Tanzania to determine the prevalence of neonatal sepsis, predictors of positive blood culture, deaths and antimicrobial susceptibility, thus providing essential information to formulate a policy for management of neonatal sepsis. This was a prospective cross sectional study involving 300 neonates admitted at BMC neonatal unit between March and November 2009. Standard data collection form was used to collect all demographic data and clinical characteristics of neonates. Blood culture was done on Brain Heart Infusion broth followed by identification of isolates using conventional methods and testing for their susceptibility to antimicrobial agents using the disc diffusion method. Among 770 neonates admitted during the study period; 300 (38.9%) neonates were diagnosed to have neonatal sepsis by WHO criteria. Of 300 neonates with clinical neonatal sepsis 121(40%) and 179(60%) had early and late onset sepsis respectively. Positive blood culture was found in 57 (47.1%) and 92 (51.4%) among neonates with early and late onset neonatal sepsis respectively (p = 0.466). Predictors of positive blood culture in both early and late onset neonatal sepsis were inability to feed, lethargy, cyanosis, meconium stained liquor, premature rupture of the membrane and convulsion. About 49% of gram negatives isolates were resistant to third generation cephalosporins and 28% of Staphylococcus aureus were found to be Methicillin resistant Staphylococcus aureus (MRSA). Deaths occurred in 57 (19%) of neonates. Factors that predicted deaths were positive blood culture (p = 0.0001), gram negative sepsis (p = 0.0001) and infection with ESBL (p = 0.008) or MRSA (p = 0.008) isolates. Our findings suggest that lethargy, convulsion, inability to feed, cyanosis, PROM and meconium stained liquor are significantly associated with positive blood culture in both early and late onset disease. Mortality and morbidity on neonatal sepsis is high at our setting and is significantly contributed by positive blood culture with multi-resistant gram negative bacteria

Reported knowledge, attitudes and practices regarding malaria and mosquito net use among women seeking antenatal care in south-western Tanzania

To improve control measures against malaria, Tanzania has increased the distribution of free and subsidized insecticide-treated mosquito nets (ITNs) to pregnant women. However, data on ownership and use of ITNs, as well as knowledge, attitudes and practices of these women regarding malaria are scarce. The objective of this study was to describe knowledge, attitudes and practices towards malaria, frequency of bed net use and level of ownership of bed nets among women seeking antenatal care in Iringa regional hospital, southern Tanzania. This cross-sectional study involved women attending antenatal clinic at Iringa Regional Hospital in south-western Tanzania. A pre-tested structured questionnaire was applied. Among the 222 pregnant women included, 173 (78%, 95%CI, 72-84.2) owned a bed net, and 150 (68%, 95%CI, 61- 75) reported to sleep always under a bed net. The use of bed nets was mentioned by 142 (64%, 95%CI, 56.2-72). Of the 46 women who did not own a bed net, seven (15.2%) reported cost as the main obstacle for owning one. About 53% (95%CI, 44-62) preferred to use mosquito nets they bought rather than the one provided for free. Several factors such as gravidity, fearing of getting malaria, knowledge on the cause, marital status, and ways used to prevent malaria were significantly associated with mosquito net ownership (all P<0.001). Education level and gravidity were associated with the behaviour to sleep always under bed nets (P<0.002). Multigravidae (2-4 pregnancies) (OR 2.1, 95%CI 1.2-4.8) and married women (OR, 1.9, 95%CI, 1.2-5.2) were more likely to own a net, as compared to primigravidae and single women. In conclusion, ITNs ownership and use among pregnant women was good and they preferred to use the nets they bought from private sector. Thus, integrating public and private sector will improve the distribution and coverage of insecticides treated mosquito among high risk groups, such as pregnant women
