Hand, Foot, and Mouth Disease (with CNS complications) is a severe form that affects the nervous system. Understanding its symptoms, causes, and treatments is crucial for early care.

What are the main causes of Hand, Foot, and Mouth Disease (with CNS complications)?

  • The primary cause is infection with enteroviruses, especially Coxsackievirus A16 and Enterovirus 71, which can sometimes affect the central nervous system.
  • Poor hygiene practices, such as inadequate handwashing, increase the risk of virus transmission among children in schools and daycare settings.
  • Direct contact with contaminated surfaces, saliva, stool, or respiratory secretions can lead to infection and complications affecting the brain and spinal cord.

Key symptoms of Hand, Foot, and Mouth Disease (with CNS complications) to watch for

  • Fever, irritability, and fatigue often appear first, signaling the early stage of the infection before rash or neurological signs develop.
  • Painful mouth sores, blisters on hands and feet, and skin rashes are typical symptoms that can worsen if the CNS is involved.
  • Neurological signs like persistent headache, neck stiffness, seizures, or confusion may indicate CNS complications requiring urgent medical attention.

How can you prevent Hand, Foot, and Mouth Disease (with CNS complications) effectively?

  • Regular handwashing with soap and water, especially after diaper changes or restroom visits, significantly reduces virus transmission.
  • Avoid close contact with infected individuals, including sharing utensils, cups, or toys, to minimize the risk of infection.
  • Maintain clean environments in schools, daycare centers, and homes, disinfecting surfaces frequently to prevent outbreaks and severe complications.
