We report two successive epidemics of aseptic meningitis due to enteroviruses (EV) observed after national immunization days against polio. Meningitis due to echovirus 30 occurred from July 1995 to the end of January 1996, mostly among children aged 0-12 years (95.1% of cases), and meningitis due to echovirus 4 occurred from May 1996 to the end of September 1996 in the same age group. There were 286 and 169 cases, respectively. Specimens from several representative cases were sent to the WHO Collaborating Center for Virus Reference and Research Laboratory for serological testing and virus detection, including polymerase chain reaction (PCR) studies. Using those tests, evidence of echovirus 30 infection was found in 44% of the children who were sampled during the first epidemic and 45.5% during the second. During echovirus 30 and echovirus 4 epidemics, a similar decline in the age-specific attack rate from 19.1/10,000 and 10.1/10,000 population aged 12 years to 2.4/10,000 and 3.6/10,000 population aged 13 years was observed, respectively.
Donating blood is an essential practice that can help save lives. Effective strategies are necessary to attract and keep blood donors to meet the demand for safe blood. To evaluate the experience of voluntary blood donors in Zanzibar, a survey was conducted, and purposive sampling was used to select participants who had donated blood multiple times. The study involved interviewing 15 repeat blood donors, and the data collected was analyzed thematically. Two main themes emerged from the analysis: motivators and barriers. Despite a few negative effects, most participants had positive experiences with repeat blood donation, and only few experienced physical reactions during or after the process. The study concludes that blood donors in Zanzibar generally have good experience towards repeat blood donation, although community participation, education, and sensitization are needed to recruit and maintain more donors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
