Insights

Aseptic meningitis epidemics in adults are primarily caused by enteroviruses, particularly echovirus types 9 and 6. These infections, often occurring in summer and autumn, generally have a favorable prognosis.

Area of Science:

  • Infectious Diseases
  • Neurology
  • Virology

Context:

  • Aseptic meningitis is a significant cause of neurological illness in adults.
  • Epidemic occurrences of aseptic meningitis have been observed, particularly during warmer months.
  • Enteroviruses are a common cause of viral meningitis.

Purpose:

  • To investigate the etiological agents and epidemiological patterns of aseptic meningitis in adults.
  • To identify the specific enteroviruses responsible for epidemic aseptic meningitis.
  • To compare clinical and laboratory findings between different enteroviral meningitis types.

Summary:

  • A 10-year study identified aseptic meningitis in 360 adults, with a small epidemic in summer/autumn 2012.
  • Enteroviruses, including echovirus types 9 and 6, were the primary cause of epidemic aseptic meningitis.
  • Sporadic cases of mumps, varicella-zoster, and herpes simplex virus meningitis were also noted.

Impact:

  • Highlights enteroviruses as the main etiological agents for adult aseptic meningitis epidemics.
  • Provides insights into the seasonal patterns and viral identification rates for aseptic meningitis.
  • Confirms the generally benign prognosis of enteroviral meningitis in adults.

Bacterial Meningitis I: Introduction01:22

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...

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: Introduction01:19

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...

Bacterial Meningitis II: Pathophysiology01:26

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial...

Introduction to Epidemiology01:26

Introduction to Epidemiology

Epidemiology, known as the cornerstone of public health, involves studying the distribution and determinants of health-related events in defined populations and applying these insights to control health issues. This is essential for understanding how diseases spread, identifying populations at greater risk, and implementing measures to control or prevent outbreaks. Epidemiology addresses not only infectious diseases but also non-communicable conditions like cancer and cardiovascular disease,...
