Following in the footsteps of smallpox: can we achieve the global eradication of measles?

Community Perception towards Mental Illness among Residents of Gimbi Town, Western Ethiopia

Background. Despite the increased burden of mental health problem, little is known about knowledge and perception of the public towards mental health problems in Ethiopia. Methods. Community based cross-sectional study was conducted among selected 845 Gimbi town residents from May 28 to June 28, 2014. Results. Out of the total study participants, 304 (37.3%) were found to have poor perception (a score below mean five semantic differential scales for positive questions and above mean for negative questions) of mental illness. Being above 28 years of age (AOR = 0.48 CI (0.23, 0.78)), private workers (AOR = 0.41 CI (0.19, 0.87)), and lack of mental health information were found to be associated with poor perception of mental illness (AOR = 0.133 CI (0.09, 0.20)). Absence of family history of mental illness was also found to be associated with poor perception of mental illness (AOR = 0.37 CI (0.21, 0.66)). Conclusions. Significant proportions of the community in Gimbi town were found to have poor perception of mental illness. Poor perception is common among old aged, less educated, private workers, those unable to access mental health information, and those with no family history of mental illness. Mental health education on possible causes, treatment options, and possible outcome of treatment to the community is required.

Measles control and the prospect of eradication

Remarkable progress has been made in reducing measles incidence and mortality as a consequence of implementing the measles mortality reduction strategy of the World Health Organization (WHO) and United Nations Children's Fund (UNICEF). The revised global measles mortality reduction goal set forth in the WHO-UNICEF Global Immunization Vision and Strategy for 2006–2015 is to reduce measles deaths by 90% by 2010 compared to the estimated 757,000 deaths in 2000. The possibility of measles eradication has been discussed for almost 40 years, and measles meets many of the criteria for eradication. Global measles eradication will face a number of challenges to achieving and sustaining high levels of vaccine coverage and population immunity, including population growth and demographic changes, conflict and political instability, and public perceptions of vaccine safety. To achieve the measles mortality reduction goal, continued progress needs to be made in delivering measles vaccines to the world's children.

Global measles elimination

Measles remains a leading vaccine-preventable cause of child mortality worldwide, particularly in sub-Saharan Africa where almost half of the estimated 454,000 measles deaths in 2004 occurred. However, great progress in measles control has been made in resource-poor countries through accelerated measles-control efforts. The global elimination of measles has been debated since measles vaccines were first licensed in the 1960's, and this debate is likely to be renewed if polio virus is eradicated. This review discusses the pathogenesis of measles and the likelihood of the worldwide elimination of this disease.

PURPOSE OF REVIEW

The purpose of this review is to summarize important papers concerning measles disease and measles-containing vaccines published in 2004.

RECENT FINDINGS

Endemic measles has been successfully controlled in the Americas and, to a lesser extent, in Europe. This has been achieved with a high uptake of two doses of a measles-containing vaccine. Even in industrialized countries, where vaccine uptake is poor, for example Japan, the disease is still a significant cause of morbidity and mortality. Vaccine failure is predominantly due to primary vaccine failure, which may, in part, be genetic in origin and related to HLA type. Measles-containing vaccines have been shown to be associated with febrile convulsions, but there is no strong evidence of a link with atopy. There is considerable evidence that there is no causal relationship with autistic disorders. In spite of this, many parents and some professionals have concerns about the safety of the vaccines, which may lead to their underuse.

SUMMARY

It is possible to eliminate measles with a high uptake of two doses of measles-containing vaccine, but concerns about safety persist and need to be tackled. More research is required into how to do this effectively and also to elucidate the causes of vaccine failure.
