    Insights

    Oral polio vaccine (OPV) significantly reduced enterovirus diseases like meningitis. Declining vaccination rates in the 21st century have led to a resurgence, particularly in unvaccinated children.

    Area of Science:

    • Virology
    • Epidemiology
    • Public Health

    Context:

    • Enterovirus infections, including serous meningitis, were a major global health concern in the mid-20th century.
    • The widespread introduction of oral poliomyelitis vaccine (OPV) dramatically reduced enterovirus disease incidence for several decades.
    • A recent increase in enterovirus meningitis cases has been observed, linked to decreased OPV revaccination levels.

    Purpose:

    • To analyze the epidemiological trends of enterovirus-induced serous meningitis.
    • To investigate the role of oral poliomyelitis vaccine (OPV) and virus interference in disease control.
    • To provide recommendations for etiological diagnosis, patient management, and vaccination strategies.

    Summary:

    • The incidence of enterovirus-induced diseases, particularly serous meningitis, sharply declined following the widespread implementation of oral poliomyelitis vaccine (OPV) starting in the 1960s.
    • This decline is attributed to the phenomenon of virus interference, where vaccine polioviruses in the gut inhibited other circulating enteroviruses.
    • However, a rise in serous meningitis cases has been noted in the 21st century, coinciding with reduced OPV revaccination rates, leaving children aged 2-14 vulnerable.

    Impact:

    • Highlights the critical role of sustained OPV vaccination programs in controlling enterovirus epidemics.
    • Emphasizes the public health importance of maintaining high vaccination coverage to prevent disease resurgence.
    • Informs diagnostic and clinical management strategies for enterovirus meningitis and underscores the value of OPV as a nonspecific preventive measure.

    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 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...

    Bacterial Meningitis

    Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
    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...

    Cryptococcal Meningitis

    Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...

    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...
