Hand, foot, and mouth disease (HFMD) is a mild exanthematous, febrile disease, but it also remains a threat to global public health. HFMD is characterized by a brief febrile illness in children and with a typical skin rash of the hand and foot, with or without mouth ulcers. However, the morphology and distribution of vesicles, as well as accompanying symptoms, are varied among atypical HFMD. An upsurge in atypical presentations of HFMD caused by A6 (CVA6), including Gianotti-Crosti-like eruptions, eczema coxsackium, petechial/purpuric eruption, and vesiculobullous exanthema, can be difficult to diagnose clinically as it may mimic other severe skin diseases, such as eczema herpeticum, varicella, disseminated zoster, and erythema multiforme major. The recognition of the distinguishing features of atypical HFMD is vital for an accurate and timely diagnosis, as is initiating appropriate laboratory evaluation and supportive care. Clinicians must identify the wide range of cutaneous and mucosal alterations caused by atypical HFMD. A systemic, high-quality overview of atypical HFMD is needed for advances in better strategies for clinical diagnosis and treatment. Hence, this review is aimed at summarizing the available data on clinical investigations and differential diagnostics to provide a scientific guide for the timely diagnosis of HFMD for preventing serious complications.

Emerging and re-emerging viral exanthems among children: what a physician should know.

Viral exanthems can present with diverse morphologies of rash, including macular, maculopapular, papular, urticarial and vesicular, or sometimes a combination of these. There has been an increasing trend towards emerging and re-emerging viral exanthems in recent years, the cause of which is multifactorial, including changing environmental conditions and altered host-vector-agent interaction. The significant temperature variations brought on by climate change and ever-increasing international travel has modified the host-agent interactions, and many re-emerging viral illnesses are now presenting with atypical presentations, including an increased frequency of affliction across broader age groups and heightened manifestations often posing as 'great imitators' mimicking a myriad of other dermatoses.

Article Synopsis
- - An unusual outbreak of Hand-foot-and-mouth disease (HFMD) occurred among college students at a university in the mid-Atlantic U.S., affecting 138 students from August to November 2018.
- - The outbreak was linked to CVA6, a less common virus associated with HFMD, and included typical signs and symptoms that were detailed alongside campus mitigation strategies.
- - This case report emphasizes the need for clinicians to recognize HFMD in older adolescents and young adults, as they may encounter similar cases in primary care and community settings.

Hand, foot, and mouth disease (HFMD) is one of the most common class C infectious diseases, posing a serious threat to public health worldwide. Enterovirus A71 (EV-A71) and coxsackievirus A16 (CV-A16) have been regarded as the major pathogenic agents of HFMD; however, since an outbreak caused by coxsackievirus A6 (CV-A6) in France in 2008, CV-A6 has gradually become the predominant pathogen in many regions. CV-A6 infects not only children but also adults, and causes atypical clinical symptoms such as a more generalized rash, eczema herpeticum, high fever, and onychomadesis, which are different from the symptoms associated with EV-A71 and CV-A16.

Article Synopsis
- * CVA6 was notably linked to an atypical rash that spread beyond typical locations like hands and mouth, affecting areas like the face and trunk, while co-infections and recurrent cases were also observed.
- * Molecular analysis categorized CVA6 as group D3 and CVA16 as group B1c, emphasizing the importance of monitoring changes in the clinical features of enteroviruses associated with HFMD.

Article Synopsis
- The study aimed to explore the clinical features of hand, foot, and mouth disease (HFMD) linked to coxsackievirus A6 (CVA6) to aid in early diagnosis, analyzing data from over 7,200 patients treated in multiple hospitals from 2013 to 2019.
- Among patients with clinically diagnosed HFMD, positive detection rates for CVA6, enterovirus 71 (EV-A71), and coxsackievirus A16 (CVA16) were found, with CVA6 being the most prevalent (31.0%).
- The study revealed that patients with CVA6 had a higher average age at onset, a significantly more common presence of fever (82.
