Insights

Echovirus type 23 was detected in young children with chronic conditions, often presenting with gastrointestinal or respiratory symptoms. This study highlights its less frequent occurrence compared to Echovirus type 22.

Area of Science:

  • Pediatric Infectious Diseases
  • Virology
  • Public Health

Background:

  • Echoviruses are known pathogens causing various clinical manifestations in children.
  • Understanding the epidemiology and clinical features of specific echovirus types is crucial for public health surveillance.
  • Echovirus type 23 has been less frequently reported compared to other enteroviruses.

Purpose of the Study:

  • To report the isolation and clinical features of Echovirus type 23 in hospitalized children.
  • To compare the occurrence of Echovirus type 23 with Echovirus type 22 during the study period.

Main Methods:

  • Retrospective analysis of viral isolates from pediatric patients.
  • Sample collection included fecal and nasopharyngeal specimens.
  • Clinical data and patient demographics were reviewed.

Main Results:

  • Echovirus type 23 was isolated from 5 children (aged 1-13 months) over a multi-decade study period.
  • The virus was detected in fecal samples (4 cases) associated with diarrhea/vomiting and nasopharyngeal secretions (1 case) with respiratory symptoms.
  • Echovirus type 23 infections were observed to be less common than Echovirus type 22.

Conclusions:

  • Echovirus type 23 can cause gastrointestinal and respiratory illness in infants and young children.
  • The lower incidence of Echovirus type 23 warrants further epidemiological investigation.
  • Clinical presentation of Echovirus type 23 resembles that of Echovirus type 22.

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 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...
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...
Viral Meningitis01:18

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...

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
