Abstract

Hand, foot and mouth disease (HFMD) associated with enterovirus 71 (EV71) is a growing public health concern. This study aimed to estimate the case-fatality of HFMD associated with EV71 on the basis of a meta-analysis. We searched PubMed, Cochrane, Web of Science, Elsevier, CNKI, Wanfang, and VIP databases. Two authors independently selected relevant studies. The pooled estimate of case-fatality was calculated using a random-effects model. Potential sources of heterogeneity were explored using subgroup analysis, sensitivity analysis and meta-regression. We identified 14 eligible studies with a total population of 112 546. The random-effects pooled case-fatality was 1.7% (95% confidence interval 1.2-2.4). The funnel plot was asymmetrical. The estimate of case-fatality was highest in mainland China (1.8%). Removal of eight local Chinese studies decreased the original estimate. The pooled case-fatality in the period of 1998-2007 (1.5%) was lower than that in the period 2008-2012 (1.8%). Control measures for HFMD associated with EV71 are essential because of the increased case-fatality over time, especially in East Asia.
