Children may experience digestive discomfort during illness, along with symptoms such as listlessness, drowsiness, and others. If these symptoms do not persist for a long time, they are typically not considered clinically as indicative of heart damage or myocarditis. In such cases, it is advisable for the child to rest at home, consume a light and liquid diet, and wait for recovery from the illness, which will naturally improve their spirits. However, if a child has a cold with extreme listlessness and feels very uncomfortable, it may be necessary to conduct a detailed blood test in a hospital to determine if there is any heart damage, myocarditis, or other special conditions. In principle, medical intervention with medications may be necessary for healing when required.

What should I do if a child has a cold and fever?

Children's colds and fevers are caused by viral or bacterial infections, with the vast majority being viral infections. First, we need to ensure that the child is well-hydrated and also manage the symptoms. When the body temperature exceeds 38.5 degrees Celsius, administer antipyretic medication to the child, such as ibuprofen suspension or acetaminophen. The interval between doses of these medications should be at least six hours. Additionally, give the child cold relief granules to alleviate the symptoms of the cold. When the body temperature is below 38.5 degrees Celsius, physical cooling methods can be applied, such as using fever-reducing patches, taking lukewarm baths, or wiping the forehead, neck, armpits, and groin—areas where large blood vessels are located—with a warm towel. Throughout the process, it is very important to keep the child hydrated. If the child's cold and fever persist, a complete blood count should be performed to check for a bacterial infection. If a bacterial infection is present, treatment with antibiotics should be administered under the guidance of a hospital doctor, based on the child’s condition. Controlling the infection is essential for reducing the fever and bringing the child's temperature down, ultimately helping the child return to normal.

How to determine whether a child's cold is caused by a virus or bacteria

When determining whether a child's cold is caused by a viral infection or a bacterial infection, you can take the child to the hospital for a routine blood test. In most cases, it is caused by a viral infection. Combined with the routine blood test, if there is an increase in white blood cell count and neutrophil count, it usually indicates a bacterial infection. If the white blood cell count is normal, or low, along with an increase in lymphocyte count or percentage, it usually indicates a viral infection. Alternatively, combining this with a C-reactive protein test, if the C-reactive protein level significantly multiplies, then it indicates a bacterial infection.

Why does a child's cold not get better?

Children often have persistent colds, which in many cases are related to improper care by parents, as well as poor immune function in the children themselves. Parents fail to adjust their children's clothing based on environmental changes in a timely manner, leading to frequent colds and recurrent colds. Secondly, due to poor immune function in children, they may constantly suffer from colds. Traditional Chinese medicine methods such as massage can be used to enhance children's immunity. In daily life, appropriate increases in outdoor sports activities can also help boost immunity. Additionally, administering oral medications that enhance immune function can improve the child's own immunity, thus avoiding the persistent occurrence of colds and preventing the onset of colds.

What medicine should a child take for cough and cold?

If children develop a cough due to a cold, like occasional mild coughing, slight nasal congestion, and runny nose, without obvious fever, and they maintain a good spirit and appetite, parents do not need to worry too much. Let the children rest appropriately, drink more warm water, and eat a light, easily digestible, and nutritious diet. A common viral cold generally has a certain self-healing capability. However, if the cough is more severe with noticeable phlegm, a significant decline in spirits, or if high fever occurs, it is then essential to visit a hospital promptly for doctors to treat the child based on their condition. Typically, children should not take cold medicines that are meant for adults, as these can have significant side effects on children. A usual viral cold infection tends to be self-limiting, so parents should closely monitor the progress of the illness, and seek medical attention promptly if the condition worsens.

What is the reason for a child's cold and persistent low fever?

During a cold, children may experience a low fever or even persistently high fever. A persistent low fever indicates that the child has not fully recovered from the illness, reflecting the recovery phase, or that the fever-reducing method being used may be inappropriate. In addition to administering oral cold medications based on the child's symptoms during a cold, oral antiviral medications can also be given to treat the illness jointly. Simultaneously, timely fever reduction measures should be implemented for children. A low fever, typically defined as a body temperature below 38.1°C, does not require oral fever-reducing medications. One can encourage the child to drink more water, frequently feed warm water, or repeatedly wipe the body with warm water, all of which can effectively reduce fever. If the low fever persists, it may be necessary to take the child to the hospital for a blood test to determine the appropriate medication for treatment based on the actual situation.
