Necrotizing fasciitis following measles vaccine administration: a case report.

BACKGROUND: The occurrence of adverse events following immunization (AEFI) in national immunization programmes is very rare; however, if they occur causality assessment is conducted to identify the associated cause. In the report, we describe a case of severe necrotizing fasciitis in the left arm of a 9-month old boy following administration of the measles vaccine. CASE PRESENTATION: A 9-month old boy presented with swelling on the left upper arm and adjoining the chest area, low-grade continuous fever, frequent passage of loose watery stool and persistent cries 24 h after measles vaccine was administered on the left upper arm. On examination, he was mildly pale, febrile, anicteric. Extensive erythema of the left upper arm occurred thereafter with extensive scalded skin lesions involving the deltoid area, the upper chest wall and arm. This was followed by desquamation of the affected areas and severe necrosis. A diagnosis of severe necrotizing fasciitis was made. A causality assessment was conducted by the state AEFI committee using the detailed AEFI investigation forms to identify the cause of the incidence. CONCLUSION: Here we present a rare case of necrotizing fasciitis which could have been caused by incorrect use of reconstituted measles vaccine. Hence we recommend training of routine immunization service providers on proper vaccine management as well as intensified supervision of immunization sessions.

Ownership of mobile phones and willingness to receive childhood immunisation reminder messages among caregivers of infants in Ondo State, south-western Nigeria

Background. The timely completion of the childhood immunisation schedule for children under the age of 1 year by caregivers is key to reducing the high morbidity and mortality of vaccine-preventable diseases among infantsglobally.Objective. To determine the ownership of mobile phones among caregivers of children under the age of 1 year, their knowledge about immunisation service delivery and willingness to receive childhood immunisation schedule reminder messages in Ondo State, south-western Nigeria.Method. A descriptive cross-sectional study using semi-structured interviewer-administered questionnaires was conducted with 615 caregivers of infants, who brought their children to clinics conducting immunisation in 24 health facilities in rural, semi-urban and urban settlements in Ondo State in December 2014.Results. The mean (standard deviation, SD) age of respondents was 28.49 (6.01) years, 76.7% were Yoruba, 91.4% were married and living with their spouses and 4.2% were single. Mobile phone ownership was 74.5% among rural-based respondents, and 95.8% among urbanbased.Forty-six percent of the respondents had good knowledge of immunisation, vaccine-preventable diseases and vaccination schedules,while 27.5% had poor knowledge. The majority of the respondents (99.7%) were willing to receive childhood immunisation reminder messages on their mobile phones. About 50% of the respondents preferred to receive reminder messages at any time, rather than specific times. The most preferred language for reminders was English (54.5%). Residing in an urban area and having post-secondary education were predictors of mobile phone ownership.Conclusion. The high mobile phone ownership level, and the willingness of caregivers of infants in this study area to receive immunisation schedule reminder messages, is encouraging, and should be optimised to improve routine immunisation uptake. However, caregivers of infants in rural areas need to be provided with mobile phone support, and trained in their usage in order to benefit from such an intervention in childhood immunisation

Measles case-based surveillance and outbreak response in Nigeria; an update for clinicians and public health professionals.

The Federal Ministry of Health recommendations for response during measles epidemics in Nigeria previously focused on case management using antibiotics and Vitamin. A supplements and did not include outbreak response immunization (ORI) campaigns. However, with the revision of the existing national technical guideline on measles casebased surveillance and outbreak response in Nigeria in 2012 in line with the World Health Organization recommendation on response to measles outbreak in measles mortality reduction settings, there is a need to update members of the Nigerian public health community on these revisions to ensure appropriate implementation and compliance. This article therefore seeks to provide clinicians and other public health professionals in Nigeria with updates on recent developments in measles case-based surveillance and outbreak response in Nigeria.

Cholera outbreak in a southwest community of Nigeria: investigation of risk factors and evaluation of a district surveillance system.

BACKGROUND: Following confirmation of cholera outbreak in a southwest community of Nigeria, we set to identify possible risk factors for contracting the disease and to evaluate the completeness as well as the representativeness of the cases reported to a district health authority. METHODS: Cholera cases were identified through an active case search that involved the review of records in health facilities and a house-to-house search using the standard case definition in the Nigeria integrated disease surveillance and response technical guidelines. Two neighborhood controls appropriately matched on age and sex for each case, were also identified. An interviewer-administered questionnaire was used to collect information on the demographic characteristics and potential risk factors. Completeness of reporting of cases notified to the district health authority was evaluated using a two source capture-recapture method. In addition, the representativeness of the reported cases was determined by comparing the age and sex distributions of notified cases to those identified through the active case search. RESULTS: Thirty-nine cases were identified, of which 22 consented to participate. Contact with a diarrhoea case at home or in the neighborhood within the last 7 days prior to illness onset in cases was significantly associated with having cholera (Matched triplets Odds Ratio 8.5, 95% CI: 1.36-52.9). The completeness of the district surveillance report was estimated to be 54%. In the district notification data compared with the active case search data, males <5 years (31% vs 18%) and females 15 years (3% vs 21%) were significantly over- and under-represented, respectively. CONCLUSION: The odds of having cholera were increased in those who had contact with a case of diarrhea. Reporting of cases to the district health authority was not complete and the surveillance data on gender and age grouping were not representative of the cases that occurred in the population. There is a need for efficient reporting of cases to the health authority during outbreaks in order to improve decision-making and public health interventions.
