Hand foot and mouth disease - Symptoms, causes and treatment

Hand, foot and mouth disease or Singapore flu is a viral infection characterized by blisters in the mouth, and rashes or red spots on the hands and feet. This disease is highly contagious and mostly affects children under the age of 5 years. Hand foot and mouth disease is mild and will heal by itself in 7-10 days.

Causes of Hand, Foot and Mouth Disease

The cause of hand foot and mouth disease is a virus coxsackie A16, which is transmitted through direct contact with the patient's body fluids, such as saliva, mucus, phlegm, and feces.

Transmission of the virus is very easy to happen during the first week. However, the virus can survive in the patient's body for a matter of weeks after symptoms disappear, so it can still infect other people. In addition to children under 5 years old, hand foot and mouth disease can also attack adults who have a weak immune system, such as people with HIV.

Symptoms of Hand Foot and Mouth Disease

Symptoms of hand, foot and mouth disease appear on the third to seventh day since they were first exposed to the virus. Early symptoms that can appear are:

  • Fever around 38-39 oC
  • Headache
  • Decreased appetite
  • Sore throat
  • Children are fussy

One to two days after the fever, red canker-like blisters will appear on the tongue, gums, and inner cheeks. In addition, skin rashes also appear on the palms of the hands and soles of the feet.

Hand foot and mouth disease is a mild health disorder. However, immediately contact a doctor or visit the nearest hospital if the following conditions appear:

Next, a physical examination will be carried out by examining the mouth and the whole body to detect the presence of blisters or rashes that mark hand, foot and mouth disease. If other diseases are suspected, swab investigations (swab) throat can also be done to detect the presence of bacteria that cause infection in the throat.
