BPSU - Enterovirus and Parechovirus Meningitis in infants <90 days of age

Surveillance of Enterovirus and Parechovirus Meningitis in infants less than 90 days of age began in July 2014 and will continue for 13 months. The study team hope to understand the clinical burden of the condition.

Overview

Approximately 85% of childhood meningitis in the conjugate vaccine era is due to enteroviruses and Human Parechoviruses (HPeV). Young infants are particularly susceptible to enterovirus and HPeV meningitis and often present with non-specific symptoms which are difficult to differentiate from serious bacterial infections. Real-time PCR is becoming increasingly available and it is anticipated that more cases will be diagnosed in the coming years.

There is, however very limited data assessing the incidence, clinical features, sequale and outcome of infants with meningitis as a result of these viruses. This study will aim to improve our understanding of enterovirus and parechovirus meningitis, and also the outcomes. Furthermore, there is no data linking the molecular subtypes of enteroviruses and HPeV currently circulating in the UK and Ireland with clinical severity, laboratory markers or outcomes. No specific antiviral treatments are licenced or in the immediate pipeline to treat these important viruses. In part the lack of good clinical data defining the burden of disease is a barrier to the development of novel antiviral therapy.  

Case definition: Any infant aged less than 90 days old with clinical symptoms of meningitis* AND laboratory confirmation of enterovirus or parechovirus from any site**

  * fever (≥38 degrees Celsius), coma, seizures, neck stiffness, apnoea, bulging fontanelle, irritability, lethargy, poor feeding

  **CSF, blood, stool, throat, peri-anal swab

Duration: July 2014 to July 2015 (13 months of surveillance) followed by a 12 month follow-up.

Funding: Paediatric Infectious Diseases Research Group, St George’s University of London
