- Abstract
Infectious agents including viruses are thought to play a role in the pathogenesis of necrotizing enterocolitis, a well-known gastrointestinal emergency in newborns. Enteroviruses are common pathogens in neonates and have been associated with outbreaks in neonatal units. Enterovirus-associated necrotizing enterocolitis has been described in 3 preterms. Spatiotemporal and molecular analyses have provided evidence of nosocomial transmission.

ENTEROVIRUS diseases , *MENINGITIS , *CENTRAL nervous system , *PICORNAVIRUSES - Abstract
Human enteroviruses (EV) are the most common cause of viral meningitis in children. Human parechoviruses (HPeV) are increasingly being recognized as a cause of central nervous system (CNS) infections and sepsis-like disease in children. Both viruses belong to Picornaviridae family. The clinical picture in EV and HPeV infections is usually nonspecific. Therefore, molecular detection of both viruses is needed for etiological diagnosis. In this case report, we describe and discuss clinical and laboratory findings of two consecutive episodes of viral meningitis caused by EV and HPeV, respectively, occurring in the first month of a newborn's life.

- Abstract
Pilgrims travelling to Saudi Arabia are commonly infected with respiratory viruses. Since the Middle East Respiratory Syndrome Coronavirus (MERS-CoV) emerged in 2012, patients with acute respiratory symptoms returning from an endemic area can be suspected to be infected by this virus. Methods: 98 patients suspected to have MERS-CoV infection from 2014 to 2019 were included in this retrospective cohort study. Upper and lower respiratory tract samples were tested by real-time RT-PCR for the detection of MERS-CoV and other respiratory viruses. Routine microbiological analyses were also performed. Patient data were retrieved from laboratory and hospital databases retrospectively. Results: All patients with suspected MERS-CoV infection travelled before their hospitalization. Most frequent symptoms were cough (94.4%) and fever (69.4%). 98 specimens were tested for MERS-CoV RNA and none of them was positive. Most frequently detected viruses were Enterovirus/Rhinovirus (40/83; 48.2%), Influenzavirus A (34/90; 37.8%) and B (11/90; 12.2%), H-CoV (229E and OC43 10/83; 12% and 7/83; 8.4%, respectively). Conclusion: From 2014 to 2019, none of 98 patients returning from endemic areas was MERS-CoV infected. However, infections with other respiratory viruses were frequent, especially with Enterovirus/Rhinoviruses and Influenzaviruses. • Most frequent symptoms leading to MERS-CoV infection suspicion were cough and fever. • No MERS-CoV detected in travelers returning from Middle East from 2014 to 2019. • Most frequently detected viruses were Enterovirus/Rhinovirus, Influenzavirus A and B.

TYPE 1 diabetes ,ENTEROVIRUSES ,DILATED cardiomyopathy ,DEVELOPED countries - Abstract
Enteroviruses (EVs) infect millions of people annually. EV infections can be asymptomatic or symptomatic with conditions ranging from mild illnesses to serious diseases such as dilated cardiomyopathy. A causal relationship between EV infections and type 1 diabetes mellitus (T1DM) has been heavily debated, with some studies suggesting that this relationship is not yet conclusive and requires additional evidence, whereas others strongly argue for this correlation. While this relationship is well investigated in some developed countries like the USA and Finland, it is understudied or neglected in other countries like Russia for many reasons such as the low incidence of T1DM. Although the Middle East and North Africa (MENA) are highly affected by T1DM, the role of EVs in the disease in MENA has not been investigated extensively. Therefore, we aimed to address the relationship between T1DM and EVs in MENA and other regions globally. [ABSTRACT FROM AUTHOR]

Several species of the genus Enterovirus cause persistent infections in humans. Human rhinovirus (HRV) infections are generally self-limiting but occasionally persistent infections have been described. This study aimed to identify persistent HRV infections and investigate the clinical and virologic characteristics of patients with persistent infections. From January 2012 to March 2015, 3714 respiratory specimens from 2608 patients were tested for respiratory viruses by using a multiplex reverse transcription–polymerase chain reaction. A retrospective study was performed. Patients with at least two specimens positive for HRV/enterovirus taken 45 days or longer apart were identified and the HRV/enteroviruses were typed. Patients with persistent infection were compared to patients with reinfection and patients with cleared infection. Phylogenetic analysis of the viral protein(VP)4/VP2 region was performed. 18 patients with persistent HRV/enterovirus infection were identified. Minimum median duration of persistence was 92 days (range 50–455 days). All but one patients with persistence were immunosuppressed. Immunosuppression and hematologic disorders were more frequent in patients with persistence (n = 18) than in patients with reinfection (n = 33) and with cleared infection (n = 25) (p = 0.003 and p = 0.001, respectively). In conclusion, this retrospective study identified HRV persistence in vivo which occurred mainly in immunosuppressed patients.
