Symptoms of hand, foot and mouth disease usually appear within 3-5 days after exposure to the infection. This time is called the incubation period.

These early symptoms may last 12-48 hours.

Mouth ulcers: After 1 or 2 days, the red spots begin to appear in the mouth, especially around the tongue, gums and the inside of the cheeks.

First, these notes are about the size of a small button button. They then quickly developed into large yellow-gray ulcers, surrounded by a red circle. There will usually be 5-10 stains in the mouth.

These marks can be very painful, making it difficult for children to eat, drink and swallow, making them very uncomfortable and fussy.

These mouth ulcers will last within 5-7 days.

Causes of hand, foot and mouth disease

Foot and mouth disease is caused by a number of different enterovirus types, but all belong to enterovirus A group. The most common types are coxsackievirus A16, A6, A10 and enterovirus 71.

The virus first spreads to the tissues in the mouth, near the tonsils, and into the digestive system.

The virus can then spread to nearby lymph nodes and pass through the blood throughout the body. The immune system will fight back the virus to prevent it from spreading to vital organs, such as the brain.

How is the disease spread?

Hand, foot and mouth disease viruses can be spread in two ways:

  1. Through the secretions from the respiratory tract - similar to the spread of flu.
  2. Through contaminated surfaces or waste (feces).

Usually the disease spreads due to the hand getting the virus from contaminated objects, then putting it near the mouth or nose. It can also be spread by inhaling the virus through droplets suspended in the air.

The virus will not spread this way once the patient has had symptoms.

However, the virus may also be present in large quantities in the stool of infected people, and may persist there for up to 4 weeks after symptoms have resolved.

3. Differentiate hand, foot and mouth disease from other diseases

Many viruses can cause redness and ulcers in the mouth - not just those that cause hand, foot and mouth disease.

However, doctors can distinguish hand, foot and mouth disease from other viral infections by:

  1. Age of the patient - hand and foot and mouth disease is most common in children under 10 years old.
  2. Symptom models - symptoms that begin with high fever and sore throat; then ulcers develop in the child's mouth, followed by rashes in the hands and feet.
  3. Expression of nodules - these nodules are smaller than chicken pox and often have different colors, sizes and shapes.

It is possible to confirm (or exclude) hand, foot and mouth disease by using a cotton swab to wipe the skin, throat or rectum of the patient and bring the test. For children, stool samples may be used.

Hand, foot and mouth disease is usually mild and resolves without treatment. Complications are rare, but may include:

Dehydration

The sores in the throat and mouth can make it hard to swallow and difficult to swallow, leading to dehydration. It is important for children to drink enough water. Encourage children to drink water and milk instead of acidic drinks like fruit juice.
