The hand foot and mouth disease kicks in with normal fever, a sore throat after one or two days, and in a few days, the rashes and blisters will begin to appear.

The hand foot and mouth disease is a viral infection mainly caused by viruses from the enterovirus family, primarily the coxsackievirus-A16 and the enterovirus71. These two are the most common causes, while other viruses from the same group can also be responsible.

Even though it is most commonly seen in younger children, adults can also get infected with hand, foot, and mouth disease. However, in the case of adults, most of the time, you won’t get a fever or any other symptoms. Also, HFMD in adults causes very itchy skin rashes, while it won’t be itchy but painful in kids.

The hand foot mouth disease is often mistaken with foot and mouth disease or hoof and mouth disease caused by a different virus and is affected in cattle and other cloven-hoofed livestock.

How does it spread?

The coxsackievirus, which causes the hand foot mouth disease is highly contagious and can spread quickly from one person to another through the following:

  • Fluid in blisters: the blisters will be filled with fluid, and this fluid might contain the virus; touching and scratching on the blisters cause these blisters to pop and fluid to come out. These fluids might have the virus which spreads the disease.
  • Discharges from the nose, saliva, or mucous.
  • Air contaminated by respiratory droplets from the infected person’s cough and sneeze.
  • Feaces
  • Close contact with the infected person.
  • Contaminated surfaces and where an infected person has touched or used things.


Your doctor mainly diagnoses the hand foot and mouth disease by considering the symptoms, patient age, and examining the nature of blisters rashes.

Also, your doctor might need to collect samples from throat, feces, and blisters to confirm the case of a hand foot and mouth disease. However, collecting samples is done only rarely.

  1. Loss of nails on fingers and toes

2. Encephalitis: encephalitis is the acute inflammation in the brain caused by a viral infection or an autoimmune disorder. Encephalitis is a severe life-threatening condition that causes the brain to swell and headaches and seizures. Encephalitis requires immediate medical attention.

3. Viral meningitis is the most common kind of meningitis, and most of the time,  it gets better without any treatment. But, in some cases, it can be hazardous and life-threatening. Viral meningitis is also called aseptic meningitis, and it is the viral infection of membranes and the erebrobrospinal fluid surrounding your brain and spinal cord.

4. Dehydration: as mentioned earlier, dehydration is the most significant complication of normal hand foot and mouth disease.
