Insights

Developing vaccines for hand, foot, and mouth disease (HFMD) is crucial. Current vaccines protect against Enterovirus 71 (EV71) but not coxsackievirus A16, highlighting the need for broader protection.

Area of Science:

  • Virology
  • Vaccinology
  • Public Health

Background:

  • Enterovirus A infections, particularly Enterovirus 71 (EV71) and coxsackievirus A16, are leading causes of hand, foot, and mouth disease (HFMD) in children.
  • These neurotropic viruses pose a significant public health threat, especially in the Asia-Pacific region, causing severe neurological complications.

Purpose of the Study:

  • To summarize the challenges in developing effective vaccines for hand, foot, and mouth disease.
  • To emphasize the need for multivalent vaccines addressing multiple enterovirus strains.

Main Methods:

  • This editorial reviews existing literature and vaccine development strategies for HFMD.
  • It analyzes the limitations of current monovalent vaccines and proposes future directions.

Main Results:

  • Formalin-inactivated EV71 vaccines provide protection against EV71 but not coxsackievirus A16.
  • A bivalent vaccine targeting both EV71 and coxsackievirus A16 is a logical next step.

Conclusions:

  • The development of multivalent HFMD vaccines, including other prevalent enteroviruses like coxsackievirus and echovirus 30, is essential.
  • Overcoming challenges in developing broad-spectrum HFMD vaccines is critical for global child health.

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...

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...

Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

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...
