A study on epidemiological characteristics and some factors related to HFMD on children under 5 years old in the period of 2015-2019 in the district was conducted in 2020. Most of the HFMD cases was found mainly in the group under 5 years old (93.7%), the highest case in the age group from 1 to 3 years old (80.3%). The prevalence in boys (59.6%) was higher than in girls (40.4%). The disease circulates all year round which the number of cases hadstarted to increase in August, peaking in October. The average number of cases per 100,000 populationwere 142, in which, number of cases found in rural areas (146) higher than in urban areas (126). Most of the cases were found mild, graded at 1 and 2a (99.7%), severe garded at 2b and 3 (0.3%). There is a relationship between children with HFMD and some social contact factors such as playing with children near theirplace (OR= 3.7), playing at crowded playgrounds (OR= 4.2), visiting doctor in the clinic (OR= 2.5) and contacting with HFMD patients (OR= 14,7), p<0.05. In order to prevent the outbreak in the district during the epidemic, it is necessary to restrict children to go to crowded places, avoid contact with other children.
