Effects of hand hygiene campaigns on incidence of laboratory-confirmed influenza and absenteeism in schoolchildren, Cairo, Egypt.

To evaluate the effectiveness of an intensive hand hygiene campaign on reducing absenteeism caused by influenza-like illness (ILI), diarrhea, conjunctivitis, and laboratory-confirmed influenza, we conducted a randomized control trial in 60 elementary schools in Cairo, Egypt. Children in the intervention schools were required to wash hands twice each day, and health messages were provided through entertainment activities. Data were collected on student absenteeism and reasons for illness. School nurses collected nasal swabs from students with ILI, which were tested by using a qualitative diagnostic test for influenza A and B. Compared with results for the control group, in the intervention group, overall absences caused by ILI, diarrhea, conjunctivitis, and laboratory-confirmed influenza were reduced by 40%, 30%, 67%, and 50%, respectively (p<0.0001 for each illness). An intensive hand hygiene campaign was effective in reducing absenteeism caused by these illnesses.

Surveillance of catheter-associated urinary tract infection in 4 intensive care units at Alexandria university hospitals in Egypt.

BACKGROUND We sought to measure the incidence rate of catheter-associated urinary tract infections (CAUTIs), identify risk factors associated with acquiring the infections; and identify the etiologic and antibiotic resistant patterns associated with CAUTIs in the intensive care units (ICUs) of a large University Hospital in Alexandria, Egypt. METHODS Prospective active surveillance of CAUTIs was conducted in 4 ICUs during a 13-month period from January 1, 2007 through January 31, 2008 in Alexandria University Hospital using the standard Centers for Disease Control National Nosocomial Infection Surveillance (NNIS) case definitions. Rates were expressed as the number of infections per 1000 catheter days. RESULTS During the study period, 757 patients were monitored after ICU admission, with either existing indwelling urinary catheters (239), or got catheters inserted after ICU admission (518), for a total duration of 16301 patient days, and 10260 patient catheter days. A total of 161 episodes of infection were diagnosed, for an overall rate of 15.7 CAUTIs per 1000 catheter days. Important risk factors associated with acquiring CAUTI were female gender (Relative risk (RR), 1.7; 95% confidence interval (CI); 1.7-4.3), and previous catheterization within the same hospital admission (RR, 1.6; 95% CI; 1.3-1.96). Patients admitted to the chest unit, patients =40 years, patients with prolonged duration of catheterization, prolonged hospital and ICU stay had a significantly higher risk of acquiring CAUTIs. Out of 195 patients who had their urine cultured, 188 pathogens were identified for 161 infected patients; 96 (51%) were Candida, 63 (33.5%) gram negatives, 29 (15.4%) gram positives. The prevalence of ESBL producers among K. pneumoniae and E. coli isolates was 56% (14/25) and 78.6% (11/14), respectively. CONCLUSION Despite infection control policies and procedures, CAUTI rates remain a significant problem in Alexandria University hospital. Using the identified risk factors, tailored intervention strategies are now being implemented to reduce the rates of CAUTIs in these 4 ICUs.

Who misses out with school-based health programmes? A study of schistosomiasis control in Egypt

There has been a recent revival of interest in school-based health programmes in developing countries as a means of reducing the morbidity observed in school-aged children, of improving their physical growth and cognitive development, and of controlling transmission of disease in the community at large. This study used data collected from a large epidemiological survey of schistosomiasis in Egypt to examine what proportion of infected children missed treatment from an established national school-based schistosomiasis control programme simply because they did not attend school. It showed that children who were not enrolled in school had a higher prevalence of infection and were more intensely infected than children who attended school. At the extreme, over 80% of infected girls in one part of Egypt could not be treated by the existing school programme because they did not attend school. If these trends are similar in other countries where school-based programmes are being developed, school-based delivery may exacerbate existing inequalities in society and ways of expanding services to children who do not attend school regularly need to be explored.

Case control study to identify risk factors for acute hepatitis C virus infection in Egypt

BackgroundIdentification of risk factors of acute hepatitis C virus (HCV) infection in Egypt is crucial to develop appropriate prevention strategies.MethodsWe conducted a case–control study, June 2007-September 2008, to investigate risk factors for acute HCV infection in Egypt among 86 patients and 287 age and gender matched controls identified in two infectious disease hospitals in Cairo and Alexandria. Case-patients were defined as: any patient with symptoms of acute hepatitis; lab tested positive for HCV antibodies and negative for HBsAg, HBc IgM, HAV IgM; and 7-fold increase in the upper limit of transaminase levels. Controls were selected from patients’ visitors with negative viral hepatitis markers. Subjects were interviewed about previous exposures within six months, including community-acquired and health-care associated practices.ResultsCase-patients were more likely than controls to have received injection with a reused syringe (OR=23.1, CI 4.7-153), to have been in prison (OR=21.5, CI 2.5-479.6), to have received IV fluids in a hospital (OR=13.8, CI 5.3-37.2), to have been an IV drug user (OR=12.1, CI 4.6-33.1), to have had minimal surgical procedures (OR=9.7, CI 4.2-22.4), to have received IV fluid as an outpatient (OR=8, CI 4–16.2), or to have been admitted to hospital (OR=7.9, CI 4.2-15) within the last 6 months. Multivariate analysis indicated that unsafe health facility practices are the main risk factors associated with transmission of HCV infection in Egypt.ConclusionIn Egypt, focusing acute HCV prevention measures on health-care settings would have a beneficial impact.

Developing strategies to control schistosomiasis morbidity in nonenrolled school-age children: experience from Egypt.

Summary Schistosomiasis is a major health problem in school‐age children in much of the tropical world. They harbour the most intense infections for both Schistosoma mansoni and S. haematobium. In Egypt, the Ministry of Health and Population (MOHP) has implemented a successful school‐based treatment programme in which children are screened and those found to be infected treated with praziquantel. High nonenrolment rates in some rural areas have a negative impact on the coverage of this programme and on its ability to reduce transmission in the community. The main aim of our study was to introduce and test a simple intervention to extend treatment to nonenrolled children using the routine MOHP schistosomiasis treatment programme. Twenty villages or ezbas in Tamia district, Fayoum governorate, with 8 schools and 1901 nonenrolled children were targeted. 88.5% of nonenrolled children attended schools to avail themselves of treatment. Coverage rates were significantly higher for girls (P < 0.001). These results are important for countries where schistosomiasis is endemic. They suggest that offering interventions in schools may not only improve the health of school attendees but also be an affordable way of extending services to out‐of‐school children.

The costs and coverage of a strategy to control schistosomiasis morbidity in nonenrolled school-age children in Egypt

Schistosomiasis still constitutes a major public health problem in some endemic parts of rural Egypt, particularly in school-aged children. The school-based health programme for schistosomiasis control adopted by the Egyptian Ministry of Health and Population (MOHP) focuses on treating enrolled schoolchildren. Children who are not enrolled or who do not attend regularly (out-of-school) do not have access to this service, in spite of evidence that the prevalence and intensity of infection are higher in these children than among children who attend school regularly. The aim of the present study was to test an intervention to extend the existing routinely applied school-based treatment to the out-of-school children. This paper reports on the costs and the coverage obtained by the intervention under 2 alternative delivery strategies: selective versus mass chemotherapy for out-of-school children. The intervention reached 88.5% of the out-of-school children at a relatively low cost per infected child of 2.29 L.E. (US

The calculations also suggest that, if the government were to implement such a programme, it would be more efficient to offer mass than selective chemotherapy at observed levels of prevalence. Sensitivity analysis showed that selective chemotherapy would be more cost-effective in areas where the prevalence of infection in out-of-school children was < 43%.

Understanding Antibiotic Use in Minya District, Egypt: Physician and Pharmacist Prescribing and the Factors Influencing Their Practices

Schistosomiasis is one of the main health problems hindering socio-economic development in Egypt. It affects millions at an early age, diminishing productivity and exerting a significant socio-economic impact. Schistosomiasis endemicity in Egypt varies in different areas. Schistosoma mansoni, with a prevalence generally ranging between 20 to 40%, has replaced Schistosoma haematobium in the Nile Delta, and the latter is now localized to upper Egypt with low endemicity levels (5-10%). The pathology of schistosomiasis consists essentially of a series of chronic inflammatory lesions produced in and around blood vessels by eggs or their products and sometimes by dead adult worms. If the ova continued to be deposited in sufficient numbers and over several years, they would ultimately lead to progressive fibrosis of the portal tracts and urinary bladder, or may be carried in blood and become trapped in the lungs, gastro-intestinal and genital tracts with only occasional association with other organs. The etiology of human pipe-stem fibrosis is still not understood. The host immune response and frequency of exposure and the time of re-infection interval appear to be involved in the overall process of fibrosis. Additional factors are probably involved in the human disease as genetic host susceptibility, malnutrition, repeated infections and repeated treatment, mixed infections including hepatitis, tuberculosis and typhoid. Reversibility of the fibrosis might be related to the proportion of the collagen types present. Immuno-histopathological demonstration of various types of collagen confirms the importance of time for administration of the treatment and period of follow-up. According to previous studies, the timing for treatment affects the reversibility of liver fibrosis emphasizing the importance of early treatment of schistosomiasis to prevent complications.
