Insights

Eighty children were studied during an echovirus 18 outbreak in Taiwan. Aseptic meningitis occurred in 31%, with a 4% fatality rate in these cases, and echovirus 18 was frequently found in cerebrospinal fluid.

Area of Science:

  • Virology
  • Pediatrics
  • Epidemiology

Background:

  • Echovirus 18 (EV-18) outbreaks can cause significant pediatric illness.
  • Understanding the clinical spectrum and outcomes of EV-18 infections is crucial for public health management.

Purpose of the Study:

  • To describe the clinical characteristics, complications, and outcomes of echovirus 18 infections in young children during a 2006 outbreak in Taiwan.
  • To identify common diagnoses and risk factors associated with severe disease, such as aseptic meningitis.

Main Methods:

  • Retrospective analysis of 80 pediatric cases of echovirus 18 infection.
  • Clinical data collection including diagnoses, comorbidities, and outcomes.
  • Echovirus 18 isolation from cerebrospinal fluid (CSF) in a subset of patients.

Main Results:

  • Eighty pediatric cases of echovirus 18 infection were identified.
  • Comorbid conditions were present in 20% of patients.
  • Aseptic meningitis complicated 31% of cases, with a 4% case-fatality rate.
  • Pharyngitis/tonsillitis (35%) and vesicular viral exanthem (33%) were the most frequent diagnoses in non-meningitis cases.
  • Echovirus 18 was isolated from 68% of CSF samples.

Conclusions:

  • Echovirus 18 caused a significant number of pediatric infections during the 2006 Taiwan outbreak.
  • Aseptic meningitis is a notable complication with a considerable fatality rate.
  • Prompt diagnosis and management are essential for improving outcomes in children with echovirus 18 infections.

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
Arboviral Encephalitis01:25

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
Bacterial Gastroenteritis01:18

Bacterial Gastroenteritis

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
Respiratory Syncytial Virus Disease01:29

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
Bacterial Meningitis01:24

Bacterial Meningitis

Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
