Background: The burden of healthcare-associated infection (HAI) is 2 to 18 times higher in developing countries. However, few data are available regarding infection prevention and control (IPC) process indicators in these countries. We evaluated hand hygiene (HH) facilities and compliance amongst healthcare workers (HCW) in a 600bed healthcare facility in Northcentral Nigeria providing tertiary care service for a catchment population of about 20 million. Methods: An in-house facility assessment tool and the World Health Organization (WHO) direct observation method were used to assess the HH facilities and compliance, respectively. Factors associated with good compliance were determined by multivariate analysis. Results: The facility survey was carried out in all 46 clinical units of the hospital. 72% of the units had no poster or written policy on HH; 87% did not have alcohol-based hand rubs; 98% had at least one handwash sink; 28% had flowing tap water all day while 72% utilized cup and bucket; and 58% had no hand drying facilities. A total of 406 HH opportunities were observed among 175 HCWs. The overall compliance was 31%, ranging from 18% among ward attendants to 82% among medical students. Based on WHO "5 moments" for HH, average compliance was 21% before patient contact, 23% before aseptic procedure, 63% after body fluid exposure risk, 41% after patient contact and 40% after contact with patients' surrounding. Being a medical student was independently associated with high HH compliance, adjusted odds ratio: 13.87 (1.70-112.88). Conclusions: Availability of HH facilities and HCW compliance in a large tertiary hospital in Nigeria is poor. Our findings confirm that HCWs seem more sensitized to their risk of exposure to potential pathogens than to the prevention of HAI cross-transmission. Inadequate HH facilities probably contributed to the poor compliance. Specific measures such as improved facilities, training and monitoring are needed to improve HH compliance.

BackgroundIn Nigeria, where malaria is endemic, greater than 70% of febrile illnesses are treated presumptively as malaria, often without a laboratory evaluation for other possible causes of fever. This cross-sectional study evaluated the presence of dengue virus infection in febrile patients, presumptively diagnosed of malaria infections in the clinic.MethodologyBlood samples were collected from 529 febrile patients (246 in Jos and 283 in Maiduguri) attending the general outpatient clinics of the Jos University Teaching Hospital (JUTH) and the University of Maiduguri Teaching Hospital (UMTH) and tested for anti-dengue immunoglobulin M (IgM) and immunoglobulin G (IgG), as well as anti-non-structural protein (NS1) by ELISA. The samples were also evaluated for presence of P. falciparum malaria parasites by microscopic examination of Giemsa-stained blood smears.ResultsThe prevalence of confirmed, highly suggestive and probable dengue virus infections categorized in relation to duration of illness since onset of fever were 2.3%, 5.5% and 1.5% respectively, while the prevalence of anti-flavivirus IgG and IgM seropositivity was 11.7%. In a total of 117 (22.1%) patients (32 in Jos, 85 in Maiduguri), malaria parasites were detected by blood smear microscopy, out of which 7 (6%) also had a positively confirmed, highly suggestive or probable dengue test result.ConclusionAlthough the high cross-reactivity of anti-flavivirus antibodies should be taken into account in the interpretation of the seroprevalence data, our findings suggest a significant presence of dengue virus in this environment, some of which may otherwise be misdiagnosed as malaria. These findings are strong enough to recommend serological screening for anti-dengue virus titer and NS1 antigen for all febrile patients, as part of fever diagnostic protocols in tropical regions. Given the prevalence of dengue virus infections, there is also a need for a dengue control program and public education to prevent outbreaks and occurrence of severe dengue complications.

During a survey of the prevalence of Candida spp. in Jos, Plateau State, Nigeria, two atypical C. albicans isolates were recovered. These two yeasts were germ tube positive, chlamydospore-negative and gave a green color on CHROMagar Candida. Molecular analysis performed by amplification of the hwp1 gene showed that these two isolates belonged to C. africana, a newly proposed Candida species closely related to C. albicans. Based on the presence or absence of an intron in DNA sequences encoding rRNA, the two C. africana, including all C. albicans isolates examined, were found to belong to genotype A and no other genotypes or species such as C. dubliniensis were found. To our knowledge, this is the first isolation of C. africana in Nigeria.
