ABSTRACT
Dengue fever is becoming one of the major public health problems in the world and its distribution has been premised on the migration of people from infected regions. This study was carried out to determine the prevalence of dengue virus IgG antibody among the patients with febrile conditions attending health facilities in Osogbo metropolis, Southwestern Nigeria. The blood samples collected between July and September, 2014 were tested for Plasmodium falciparum and the sera were subsequently subjected to Enzyme Linked Immunosorbent Assay (ELISA) to detect the dengue virus IgG antibody. Of the hundred consented participants screened, 77% were sero-positive for dengue virus IgG antibody while 41% were positive for P. falciparum. Thirty-three (33%) of the participants were positive for both dengue virus IgG antibody and P. falciparum. No significant difference was found in the prevalence of dengue virus IgG antibody and malaria among the participants (P>0.05). The high prevalence of dengue virus IgG and malaria signifies the need by the government of Osun State to sensitize residents and institute urgent measures to mitigate the resultant effects of morbidity and mortality due to dengue fever and dengue hemorrhagic fever which has hitherto appeared to be alien to the area.
ABSTRACT
This study; assessing existing practices in the operating theatre regarding hand washing; disinfection and sterilisation; was conducted at Khartoum North Teaching Hospital. As far as we know; this is the first study of its kind since the inauguration of the hospital in 1950. A total of 55 health personnel working in the operating theatre participated in the study. These included nurses and environmental service personnel (housekeepers and sterilisation and disinfection personnel). Knowledge and practice were evaluated using multiple choice and direct interview questions. Operation theatre sterilisation and disinfection practices were monitored using checklists modified from World Health Organization recommendations. A marked lack of knowledge and defective attitudes and practices were observed among a large number of personnel. It was observed that 51of the nurses were 46 years of age or older and that two-thirds had only a primary and intermediate school level education. The study recommends the upgrading of the operating theatres and additional training and education of staff. Theatres should be provided with facilities for proper disinfection and waste disposal. Qualified nurses should be employed. We also recommend the establishment of an infection control committee. The role of the committee would include the planning and execution of hygiene policies. In addition; planning and organising training courses in infection control should be seen as a priority
