Insights

Human bocavirus (HBoV), a novel parvovirus, was detected in 7.2% of young children with respiratory infections in India. This virus is linked to both upper and lower respiratory illnesses, showing no seasonal pattern.

Area of Science:

  • Virology
  • Pediatrics
  • Infectious Diseases

Background:

  • Human bocavirus (HBoV) is a recently identified human parvovirus.
  • HBoV has been associated with respiratory tract diseases in children.

Purpose of the Study:

  • To investigate the prevalence and clinical presentation of HBoV in young children with acute respiratory tract infections in India.

Main Methods:

  • Nasopharyngeal aspirates were collected from 305 children under 5 years old with acute respiratory tract infection.
  • Samples were screened for HBoV using two independent sets of polymerase chain reaction (PCR).

Main Results:

  • HBoV was detected in 22 children (7.2%), all presenting with acute respiratory infection.
  • The most common symptoms observed were cough (95%), runny nose (64%), and fever (59%).
  • HBoV was co-detected with respiratory syncytial virus in one case and influenza A virus in another.

Conclusions:

  • HBoV is prevalent in young children with respiratory infections in India.
  • HBoV is associated with both upper and lower respiratory tract diseases.
  • No seasonal distribution was observed for HBoV infections.

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...
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...

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:
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...
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...
