Abstract:

Objective To analyze the epidemiological characteristics of hand, foot and mouth disease (HFMD) in Guizhou Province from 2010 to 2021 for theoretical basis to perfect the prevention and control measures for this infection. Methods The case information on HFMD reported in Guizhou Province between 2010 and 2021 was retrieved from the China Disease Prevention and Control Information System, and then analyzed pertinent to the distribution and pathogens of the virus by descriptive epidemiology. Results In total, 437 511 cases of HFMD were reported in Guizhou Province from 2010 to 2021. The incidence reported annually was between 67.98 and 162.90 per 100 000 population, the average annual incidence was 101.80/100 000 population. Of the 437 511 cases, 8 349 cases were severe, with a rate of severe case being 1.91%, and there were 171 deaths. Most of the cases showed bimodal distribution, which occurred in April-June and September-November respectively. Cases of HFMD were reported in across the province, and the most hit areas were Zunyi (114 669 cases, 26.21%), Guiyang (110 460 cases, 25.25%) and Liupanshui (39 874 cases, 9.11%). The high-risk population was children living at home (345 577 cases, 78.99%), and children aged 0-5 years were most reported (413 965 cases, 94.62%). In terms of sex distribution, there were more males, with a sex ratio of 1∶0.64. From 2010 to 2012, enterovirus A71 (EV-A71) was the predominant strain of HFMD, and after 2013, other enteroviruses became the dominant strain in Guizhou Province. Conclusion In recent years, the incidence of HFMD in Guizhou Province showed a fluctuating downward trend. Children under 5 years should be the focus for prevention and control, at the same time, the monitor of virus type should be strengthened.
