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) 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.

Hand, foot, and mouth disease is a very infective infection. It's caused by viruses from the Enterovirus genus, among the Enterovirus genus coxsackievirus is most commonly found associated with Hand , Foot and Mouth disease. Hand, foot and mouth disease (HFMD) causes rashes or vesicular lesions in the affected individuals and lesions are found in extremities and upper extremity lesion is more common along with feet and mouth. It is mostly seen in school going children, and causative agents are likely Enterovirus-A (EV-A) species, including Coxsackievirus-A16 (CV-A16) and Enterovirus-71 (EV-71) [1]. Hand , Foot and Mouth Disease is usullay mild and selimiting. In the affected patient's rst identied by a brief prodromal fever, followed by pharyngitis, mouth ulcers and rash on the hands and feet. The disease is caused by numerous members of the Enterovirus genus of the family Picornaviridae e.g. Coxsackievirus type A (CA) and Enterovirus 71 (EV71), and the clinical features are not identiable and distinguishable from virus to virus. [2] . Young children have the highest risk of getting hand, foot, and mouth disease. Risk increases if they attend daycare or school, as viruses can spread quickly in these facilities. Children usually build up immunity to the disease after being exposed to the viruses that cause it. This is why the condition rarely affects people over age 10. However, it's still possible for older children and adults to get the infection, especially if they have weakened immune systems. EV71 is a human enterovirus A species causing infection in clildren[3,4] . Clinically though it is mild symptoms and self limiting initially, such as a fever along with unraised colorless spots, and bumps on the hands, feet, and mouth. In some patients with severe disease several neurological complications (including cephalomeningitis, encephalitis, and neurogenic pneumonedema) and circulatory disorders. Occasionally, it even causes death [5]. Therefore, an early indicator of EV71 infection with neurological involvement is crucial for appropriate management [6]. Hand, foot, and mouth disease by enterovirus infection repots severe complications (such as brain stem encephalitis, neurogenic pulmonary edema, and other fatal complications) and a high mortality due to HFMD are more frequently related to EV71 infection[7,8] .

Varicella Zoster Infection

Background: Hand, foot and mouth disease (HFMD) is a medical condition endemic among children in South-East Asia, including Indonesia and, more specifically, Banjarmasin – the capital of South Sulawesi. The disease is mediated by Enterovirus 71 and Coxsackievirus 16 which attack the oral cavity, hands, feet, buttocks and genital areas. One differential diagnosis of this disease is Primary Varicella Zoster infection. Both diseases have similar clinical symptoms but different etiologies which can precipitate errors in the administration of therapy Purpose: To elucidate the distinction between HFMD and Primary varicella zoster infection. Case: An 8 year-old male sought treatment complaining of ulcers on the upper maxillary gingiva followed by the appearance of itchy and painful lesions affecting the nose, upper lip, hands and feet. The patient’s mother reported his history of 39oC fever followed by the development of red spots and ulcers on the face, hands and feet which caused itching. Clinically, it is similar to Primary varicella zoster infection which can affect any part of the body. The patient only used an immunomodulator once a day and was actively seeking available healthcare. Case management: Extraoral examination confirmed the presence of multiple erythematous vesicles and ulcers, 2 mm in diameter, which caused a sensation of itching around the nose and upper lip region. Multiple painful and itchy red macules and vesicles, 3-6 mm in diameter, appeared not only on the patient’s palms, back of the hands and feet. Intraoral examination of the right maxillary gingiva revealed multiple painful ulcers, 1-2 mm in diameter and yellowish in appearance, surrounded by erythema. The results of history-taking implied that no lesions appeared on other parts of the body. Conclusion: While these conditions share similar clinical manifestations, their contrasting etiologies require different treatments. The ultimate diagnosis can be determined clinically by the dentist, thereby preventing errors in the administration of therapy.

Etiological Agents

Hand, foot, and mouth disease (HFMD) commonly produces herpangina, but fatal neurological complications have been observed in children. Enterovirus 71 (EV-A71) and Coxsackievirus 16 (CV-A16) are the predominant viruses causing HFMD worldwide. With rising concern about HFMD outbreaks, there is a need for an effective vaccine against EV-A71 and CV-A16. Although an inactivated vaccine has been developed against EV-A71 in China, the inability of the inactivated vaccine to confer protection against CV-A16 infection and other HFMD etiological agents, such as CV-A6 and CV-A10, necessitates the exploration of other vaccine platforms. Thus, the antigenic peptide-based vaccines are promising platforms to develop safe and efficacious multivalent vaccines, while the monoclonal antibodies are viable therapeutic and prophylactic agents against HFMD etiological agents. This article reviews the available information related to the antigenic peptides of the etiological agents of HFMD and their neutralizing antibodies that can provide a basis for the design of future therapies against HFMD etiological agents.
