RESUMO
BACKGROUND: Immunization programs suffer recurrent setbacks in developing countries. PURPOSE: We evaluated the knowledge and opinion of parents towards childhood immunization. MATERIALS AND METHODS: A cross-sectional study was conducted among 2400 parents/guardians in two major Anambra cities. RESULTS: The male:female ratio was 1:1 and about two-third (64.3%) of respondents were aged 21-40 years. The majority were married (85.0%), Christians (88.3%), and had heard about childhood immunization (92.3%) mainly from formal settings (56.5%). A little above half (56.2%) of them correctly cited "disease prevention" as reason for childhood immunization. A larger proportion of those that gave this correct response worked in tertiary institutions and had post-secondary school education (p<0.001). The majority of the respondents appropriately agreed or disagreed with opinions that can influence immunization uptake. However, some of them did not agree that immunization was important during the first year of life (16.7%) or afterwards (23.1%); to ensure full immunization (22.8%) or maintain proper immunization records (25.6%) of their children; and to actively support childhood immunization (33.9%). Likewise, some respondents would withhold immunization for perceived fear of adverse reactions (30.7%) or if naturally acquired infection was perceived to confer better protection (28.2%). Respondents who worked in tertiary institutions, and had higher education or family income were more likely to agree or disagree appropriately to opinions. Males had comparable opinions with females although females seemed to do better in opinions that reflect actual vaccination practice. CONCLUSION: Awareness of the term "immunization" was high although knowledge of its indication did not measure up with this awareness, especially among the less educated. Most parents, especially those who worked in tertiary institutions,r had higher income, or education, were favorably disposed towards opinions that could positively influence immunization uptake. Efforts should be intensified at improving awareness on the indication, benefits and safety of immunization, and improving public opinions in order to optimize childhood immunization.
RESUMO
Extended-spectrum ß-lactamase (ESBL)-producing organisms have become a serious challenge in healthcare delivery globally. The prevalence of ESBL carriage in healthy and sick children in Enugu, Nigeria, was bacteriologically investigated in this study. Four hundred and twenty-two biological samples (mid-stream urine and feces) were bacteriologically analyzed. The isolates were screened for ESBL production using Clinical and Laboratory Standards Institute (CLSI) breakpoints. The suspected ESBL producers were confirmed using double disc synergy test method. Out of the 162 isolates screened, 32 (19.8%) were confirmed as ESBL positive, with a prevalence of 25.32% among sick children in Enugu State University Teaching Hospital (ESUTH), Parklane, Enugu and 13.89% in apparently healthy children in a community setting. Klebsiella spp. and Escherichia coli had the highest prevalence of 34.6% and 28.6%, respectively; Citrobacter spp. and Enterobacter spp. were 18.2% and 16.7%, respectively. The ESBL positive isolates were resistant to sulfamethoxazole/trimethoprim (100%), tetracycline (100%), kanamycin (96.9%), nitrofurantoin (84.4%), ciprofloxacin (68.6%), and chloramphenicol (62.5%) but susceptible to meropenem (100%), colistin (56.3%), and gentamicin (50%). Klebsiella spp. had the highest ESBL occurrence among sick children while E. coli had the highest ESBL occurrence among healthy children in Enugu. All ESBL-positive isolates were multiply resistant to conventional antibiotics. The emergence and spread of ß-lactamase-producing Enterobacteriaceae in hospital and community environments highlight the possibility for an infection outbreak if not checked.
