1. What to do if your hand, foot and mouth have a fever of 39 degrees

Hand, foot and mouth disease mainly occurs in children under 4 years old, but adults can also get the disease, so it can be said that everyone is susceptible. The symptom of hand, foot and mouth disease is that after infection, one only gains immunity to that type of virus, and has no cross-immunity to reinfection with other types of viruses.

May be accompanied by symptoms such as cough, runny nose, and loss of appetite. Some cases only present as rash or herpangina. Most patients recover within a week and the prognosis is good. In some cases, the rash may be atypical, such as appearing in a single area or only as maculopapular rash.

2. Symptoms of severe cases

In a few cases (especially those under 3 years old), the disease progresses rapidly, with meningitis, encephalitis (brainstem encephalitis is the most dangerous), encephalomyelitis, pulmonary edema, circulatory disorders, etc. occurring within 1 to 5 days of onset. In very rare cases, the condition is critical and can lead to death, and survivors may have sequelae.

Physical examination may reveal signs of meningeal irritation, weakened or absent tendon reflexes, and positive pathological signs such as Babinski's sign.

The heart rate increases or decreases, the pulse becomes shallow or weak or even disappears; the blood pressure increases or decreases.

2. What should I do if my child has a fever of 39 degrees?

According to body temperature conditions, fever is divided into: low fever: 37.4 ~ 38 ℃; moderate fever: 38.1 ~ 39 ℃; high fever: 39.1 ~ 41 ℃; hyperpyrexia: above 41 ℃. There are many causes of fever in children. Upper respiratory tract infection, gastroenteritis, tonsillitis, pneumonia and all infectious diseases may cause fever symptoms.

In addition, babies under one year old may also develop fever due to urinary tract infections, gastrointestinal diseases, and hand, foot and mouth disease. In many cases, a doctor must be consulted to find out the real cause of the fever. If the fever is below 38 degrees, consider taking physical cooling measures, such as wiping the body with warm water or applying ice packs; if the fever is above 38.5 degrees, consider taking medication to reduce the fever, such as Tylenol.

First, cool the child down physically by using 35%-45% alcohol or warm water for a sponge bath, mainly in areas where large blood vessels are distributed, such as the forehead, neck, armpits, groin and thighs. After taking the medicine, pay attention to observe your baby's symptoms to see if they persist. After the fever of a common cold subsides, the chance of recurrence is low. Generally, if there is inflammation in the body, fever is prone to recurring, so if symptoms of recurring fever occur, you should seek medical attention as soon as possible.
