Insights

Rotavirus infection can cause severe illness. This case report details a fatal outcome in a child due to rotavirus-associated myocarditis and pneumonitis.

Area of Science:

  • Pediatric Infectious Diseases
  • Cardiology
  • Pulmonology

Background:

  • Rotavirus is a leading cause of gastroenteritis in young children globally.
  • While typically self-limiting, severe complications are rarely reported.

Observation:

  • A 2-year-old boy presented with severe gastroenteritis.
  • The child experienced sudden cardio-respiratory arrest and expired.
  • Autopsy examination was performed.

Findings:

  • Autopsy revealed evidence of myocarditis (inflammation of the heart muscle) and pneumonitis (inflammation of the lungs).
  • These conditions were directly associated with rotavirus infection.
  • This represents a previously unreported fatal consequence of rotavirus.

Implications:

  • Highlights the potential for severe, systemic complications of rotavirus infection beyond gastroenteritis.
  • Underscores the importance of considering rotavirus in the differential diagnosis of unexplained pediatric cardio-respiratory failure.
  • Suggests a need for further research into the mechanisms and risk factors for severe rotavirus-associated organ damage.

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...
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...

Acute Respiratory Failure-II01:21

Acute Respiratory Failure-II

Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
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...
