Insights

Enterovirus 68 was found in Japanese children with respiratory infections and febrile convulsions in 2010. These unique strains had genetic differences, highlighting the virus

Area of Science:

  • Virology
  • Infectious Diseases
  • Pediatrics

Background:

  • Enterovirus 68 (EV-D68) is a significant respiratory pathogen.
  • Previous EV-D68 outbreaks have been reported globally.
  • Understanding local EV-D68 epidemiology is crucial for public health.

Purpose of the Study:

  • To characterize Enterovirus 68 strains detected in Japan during 2010.
  • To investigate the genetic features of these strains.
  • To determine the association of EV-D68 with respiratory tract infections in Japanese children.

Main Methods:

  • Specimen collection from children with respiratory tract infections and febrile convulsions.
  • Molecular detection and characterization of Enterovirus 68.
  • Genetic analysis of viral strains, focusing on the 5' untranslated region.

Main Results:

  • Enterovirus 68 was detected in 15 pediatric specimens (14 respiratory, 1 febrile convulsions).
  • The identified EV-D68 strains exhibited deletions in the 5' untranslated region.
  • Genetic analysis revealed distinctness from previously reported EV-D68 strains.

Conclusions:

  • Enterovirus 68 circulated in Japan in 2010, associated with pediatric respiratory infections.
  • The unique genetic profile of these strains warrants further investigation.
  • This study contributes to the understanding of EV-D68 epidemiology in Japan.

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 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...

Acute Pharyngitis

Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Diphtheria01:28

Diphtheria

Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...
