Enterovirus 71 (EV71) often causes large outbreaks of diseases among children worldwide and its pathogenesis remains unclear. The aim of the present study was to investigate the association between interferon-inducible protein 10 (IP-10) polymorphism in children with EV71 infection. Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) were performed to analyze the gene polymorphisms of IP-10 (-1596C/T) in 58 EV71-infected and 48 control patients. The results showed that in EV71-infected patients the frequency of carrying CT + TT genotype and T allele is 10.3 and 6.0%, respectively, which is significantly lower than that of the controls (29.2 and 15.6%, respectively). Individuals with T allele had a lower risk of EV71 infection [odds ratio (OR) = 0.35, 95% confidence interval (CI), 0.13-0.89]. The results of this study indicated that -1596T allele for the IP-10 gene may be a beneficial factor for EV71 infection.

Unlabelled: Platelet factor 4 (PF4) has been shown to regulate several viral infections. Our previous study demonstrated that PF4 inhibits the entry of enterovirus A 71 (EV71) and coxsackievirus A16 (CA16), which cause hand, foot, and mouth disease (HFMD). In this study, we report that PF4 also inhibits the circulating HFMD pathogen coxsackievirus A6 (CA6) and the re-emerging enterovirus D68 (EVD68).

Article Synopsis
- METTL3 is a key enzyme that adds m6A modifications to RNA, impacting innate immunity and viral responses.
- Infection with EV71 increases METTL3 levels in both IFN-deficient and proficient cells through changes in transcription and protein modifications.
- METTL3 regulates antiviral responses through both m6A-dependent and independent mechanisms, suggesting it could be a valuable target for developing antiviral treatments.

Background: Hand, foot, and mouth disease (HFMD) is a highly contagious viral illness. Understanding the long-term trends of HFMD incidence and its epidemic characteristics under the circumstances of the enterovirus 71 (EV71) vaccination program and the outbreak of COVID-19 is crucial for effective disease surveillance and control.
Objective: We aim to give an overview of the trends of HFMD over the past decades and evaluate the impact of the EV71 vaccination program and the COVID-19 pandemic on the epidemic trends of HFMD.

To analyze the nationwide epidemiological characteristics and trend of hand, foot and mouth disease (HFMD) fatal cases from 2008 to 2022 and provide evidence for the prevention and control of HFMD. The information on HFMD fatal cases during 2008 to 2022 was collected from the National Notifiable Disease Surveillance Reporting System of China. Data of the epidemiological characteristics was analyzed by R 4.

Inflammatory cells infiltration in the cerebrospinal fluid is a hallmark of severe enterovirus 71 (EV71) infection, but which type of immune cells are critical for severe EV71 infection remains unclear. Here, we observe that both neutrophils and macrophages are increased in the brains of patients and mice with severe EV71 infection, and the depletion of neutrophils but not macrophages results in a marked enhancement of survival of EV71-infected mice. Furthermore, CCR1/3 may play an important role in CCL3 facilitating the accumulation of neutrophils in the brains of patients.
