Hand, foot, and mouth disease (HFMD) is most frequently caused by several serotypes of human enterovirus (EV) including Enterovirus 71 (EV-A71), coxsackievirus A16 (CV-A16), or other types of EV. The aim of this study was to determine the epidemiological characteristics of HFMD and to describe the epidemiologic characteristics of HFMD among severe and mild cases. We collected 4760 HFMD cases in Hangzhou from 2016 to 2018. Specimens from these cases were collected and tested for EV-A71, CV-A16, CV-A6, CV-A10, CV-A2, and CV-A5 by reverse transcriptase polymerase chain reaction. From 2016 to 2018, the prevalence of HFMD was seasonal each year. Among the 4760 probable HFMD cases, 3559 cases were confirmed (74.8%), including 426 cases of EV-A71 infections (8.9%), 249 cases of CV-A16 infections (5.2%), and 2884 cases of other EV infections (60.6%). The percentage of other EV infections was more than 80%, which increased year by year. Random selection of samples for detection of other EV infections in 2017 and 2018, among the 1297 cases, showed there were 835 (64.4%) cases of CV-A6 infections, 177 (13.6%) cases of CV-A10 infections, 100 (7.7%) cases of CV-A2 infections, 40 (3.1%) cases of CV-A5 infections, 3 (0.02 %) cases of mixed infections, and 11.0% untyped EV infections. Preschool children were still the primary population susceptible to HFMD. In severe cases, EV-A71 infection was the main cause. Characterizing the epidemiology and the relationship between severe and common cases of HFMD would provide relevant evidences for the prevention and treatment of HFMD.

Abstract Background Hand, foot and mouth disease (HFMD) is most frequently caused by several serotypes of human enterovirus (EV) including Enterovirus 71 (EV71), Coxsackievirus A16 (CV-A16) or other types of EV. Children under 5 years old are the most susceptible to HFMD. The aim of this study was to determine the epidemiological characteristics and the relationship between severe and mild HFMD. Methods We collected 4760 probable HFMD cases with skin papular or vesicular rashes on the hands, feet, mouth or buttocks in Hangzhou from 2016 to 2018. Specimens of these cases were collected and the pathogen of EV71, CV-A16, CV-A6, CV-A10, CV-A2 and CV-A5 was classified by RT-PCR. Then the pathogen distribution and clinical status of children with HFMD were described. Results From Jan. 1, 2016 to Dec. 31, 2018, the incidence and prevalence of HFMD were seasonal each year. Among the 4760 probable HFMD cases, 3559 cases were confirmed (74.8%, 3559/4760), including 426 cases of EV71 infections (8.9%, 426/4760, 249 cases of CV-A16 infections (5.2%, 249/4760) and 2884 cases of other enteroviruses infections (60.6%, 2884/4760). The percentage of EV positive HFMD cases with non-EV71 and non-CV-A16 was more than 80% (2884/3559), which increased year by year. The percentage of EV71 decreased year by year in the last three years especially in 2018. Among the 1297 cases randomly selected of other EV infections in 2017 and 2018, there were 835 (64.4%) cases of CV-A6 infections, 177 (13.6%) cases of CV-A10 infections, 100 (7.7%) cases of CV-A2 infections, 40 (3.1%) cases of CV-A5 infections, 3 (0.02%) cases of mixed infections and 11.0% untyped enteroviruses infections. Preschool children were still the primary population susceptible to HFMD, and the age of the children infected with other enteroviruses tended to be younger. In severe cases, EV71 infection was the main cause. Conclusions The other EV especially CV-A6 increased obviously and EV71 decreased obviously in the three years. Characterizing the epidemiology and the relationship between severe and common cases of HFMD would provide relevant evidences for the prevention and treatment of HFMD.

Epidemiological Characteristics

Objective To study the epidemiological characteristics of hand, foot and mouth disease (HFMD) in Tongzhou District, Beijing between 2013 and 2017. Methods Data on HFMD infections from 1 January 2013 to 31 December 2017 were collected from the Notifiable Infectious Diseases Reporting Information System and analysed. Serotyping of enteroviruses from samples from patients with HFMD was undertaken using reverse transcription–polymerase chain reaction. Results A total of 15 341 patients with HFMD were reported and 32 patients (0.2%) were classified as having severe HFMD. The annual mean incidence rate of HFMD was 219.3/100 000 of the general population. The incidence and case-severity rates of HFMD generally decreased between 2013 and 2017. In the floating migrant population, the incidence and cases-severity rates of HFMD were significantly higher than in the local population. The peak incidence and severity-case rates were at 2 years of age and > 90% of patients were ≤5 years. Enterovirus A71 and Coxsackievirus A16 were the predominant pathogens in 2013–2017. Conclusions During the 5-year period 2013–2017, the incidence rate and case-severity rate of HFMD generally decreased in Tongzhou District, Beijing. The floating migrant population and children ≤5 years of age were at the highest risk of HFMD.

We report a case of hand, foot and mouth disease (HFMD) in a 5-year-old male from Merida City in the Yucatan Peninsula of Mexico. A clinical and physical examination revealed that the patient had symptoms typical of HFMD, including fever, fatigue, odynophagia, throat edema, hyperemia, lesions on the hands and feet, and blisters in the oral cavity. The patient fully recovered after a convalescence period of almost three weeks. Reverse transcription-polymerase chain reaction and nucleotide sequencing revealed that the etiological agent was enterovirus 71 (EV71). The sequence has greatest (90.4%) nucleotide identity to the corresponding regions of EV71 isolates from the Netherlands and Singapore. Although HFMD is presumably common in Mexico, surprisingly there are no data in the PubMed database to support this. This case report provides the first peer-reviewed evidence of HFMD in Mexico.

Hand, foot, and mouth disease (HFMD) also known as vesicular stomatitis with exanthema, first reported in New Zealand in 1957 is caused by Coxsackie virus A16 (CVA16), human enterovirus 71 (HEV71) and occasionally by other HEV-A serotypes, such as Coxsackie virus A6 and Coxsackie virus A10, are also associated with HFMD and herpangina. While all these viruses can cause mild disease in children, EV71 has been associated with neurological disease and mortality in large outbreaks in the Asia Pacific region over the last decade. It is highly contagious and is spread through direct contact with the mucus, saliva, or feces of an infected person. This is characterized by erythrematous papulo vesicular eruptions over hand, feet, perioral area, knee, buttocks and also intra-orally mostly in children, typically occurs in small epidemics usually during the summer and autumn months. HFMD symptoms are usually mild and resolve on their own in 7 to 10 days. Treatment is symptomatic but good hygiene during and after infection is very important in preventing the spread of the disease. Though only small scale outbreaks have been reported from United States, Europe, Australia Japan and Brazil for the first few decade, since 1997 the disease has conspicuously changed its behavior as noted in different Southeast Asian countries. There was sharp rise in incidence, severity, complications and even fatal outcomes that were almost unseen before that period. There are reports of disease activity in different corners of India since 2004, and the largest outbreak of HFMD occurred in eastern part of India in and around Kolkata in 2007and Bhubaneswar, Odisha in 2009. In recent years there are cases of HFMD have been seen in Bangladesh also. Although of milder degree, continuous progress to affect larger parts of the neighboring may indicate vulnerability of Bangladesh from possible future outbreaks.Bangladesh J Child Health 2016; VOL 40 (2) :115-119
