What Causes HFMD In Children?

Hand, foot, and mouth disease is caused by the coxsackievirus, mostly coxsackievirus A16. Coxsackievirus belongs to a group of viruses called enteroviruses.

Other types of enteroviruses can also cause HFMD. But Coxsackievirus A16 and Enterovirus 71 have been mostly associated with HFMD outbreaks in children (2).

HFMD is highly contagious and spreads easily from person to person. Your child may contract hand, foot, and mouth disease by coming in touch with an infected person’s:

  • Saliva. It can directly transmit the virus to your child. Even sharing the same cup or plate can make it contagious.
  • Respiratory discharge such as a sneeze or cough. If your kid comes in contact with an infected person’s cough or sneeze, or breathes in the same air, they can get infected.
  • Fluids from the blisters. Your child can contract the disease when they touch or come in skin contact with the fluid discharge from blisters.
  • Feces. HFMD virus can also transmit through the fecal-oral route. So, if kids touch soiled diapers or come in contact with a soil or surface contaminated with feces of an infected person, they may catch the virus.
  • Skin contact with an infected person. A close physical contact, such as a handshake or a hug, can be a source of infection.
  • Contact with any object that is infected. Viruses can survive on inanimate objects; therefore, touching an object used by an infected person can transmit the virus.

If somebody in your family, close neighborhood or the child’s daycare is having the disease, then your child is likely to get it. Therefore, keep an eye on the symptoms.

What Are The Complications Of HFMD?

Usually, HFMD runs its course and the affected child recovers on their own without any complications.

The greatest and most common complication is dehydration. The sores inside the mouth and throat make swallowing difficult, making the children reluctant to drink water.

Any other serious complications are rare but children with low immunity are likely to have (4):

  1. Viral meningitis. This causes inflammation of the meninges or the membranes that surround the brain and spinal cord. Viral meningitis results in a headache, a fever, and a stiff neck.
  1. Encephalitis. The inflammation of the brain can be potentially fatal but is very rare.

As mentioned above, HFMD subsides on its own and doesn’t require a visit to the doctor. However, in some cases, you may have to.

When To See A Doctor?

  • High dehydration as the child doesn’t pass urine for more than eight hours or their mouth becomes very dry
  • The symptoms are persisting even after ten days

The doctor will do a diagnosis to confirm if it is HFMD or any other infection.
