How long does a cold last? Normally, a common cold can recover within 5-7 days. Influenza might have a slightly longer duration, generally requiring 7-10 days to resolve. The specific situation also depends on the virulence of the cold virus, the body's immune capability, the amount of virus, and the body’s resistance. There are some clinical variations. The common cold itself is a contagious, self-limiting disease, caused by viral infections like influenza or parainfluenza, leading to respiratory infections. The main treatment involves drinking plenty of water, resting, symptom management, and preventing complications.

How many days will it take for the baby to recover from a cold?

Generally speaking, if a baby has a cold caused by a common viral infection and receives symptomatic treatment, the symptoms can usually be controlled within three to five days. If it is a severe cold or influenza, the symptoms can be more severe and may include repeated fever, runny nose, and sneezing, lasting longer, about seven days, or even up to ten days. If there is a bacterial infection following the cold, the duration may be even longer and would require specific analysis based on the actual situation.

How to take care of a child with a cold

How to take care of a child during a cold? First, it is essential to ensure that the child rests in bed. Provide the child with plentiful water, offering small amounts frequently. If the child does not want to drink water, you can appropriately add some juice or glucose water. Also, monitor the temperature changes, generally measuring the temperature under the armpit. Second, it is crucial to keep windows open for ventilation at home, avoiding too cold or too hot environments, as neither is conducive to the child’s recovery from illness. Third, based on the changes in temperature, adjust the child’s clothing accordingly but avoid dressing the child too warmly or covering too thickly, as this can hinder heat dissipation. This is not only detrimental to the child’s recovery but can also exacerbate the illness and potentially lead to heat rash. Fourth, if the child sweats excessively, be sure to wipe the sweat timely and change their clothes. Fifth, in terms of diet, adopt a strategy of small, frequent meals that are light and easy to digest. The child should avoid eating fish, shrimp, spicy, and other stimulating foods. If the child has poor appetite or indigestion, do not force-feed them. Instead, frequently massage their abdomen, and if necessary, administer oral medication to aid digestion. Sixth, ensure adequate caloric intake and that the child urinates frequently and has regular bowel movements. Seventh, actively apply symptomatic treatment for the child and avoid the misuse of antibiotics. If the temperature persists for more than three days or if the condition worsens, it is imperative to visit the hospital promptly to avoid delaying the child's condition.

Is a wind-heat cold contagious?

In traditional Chinese medicine, a cold caused by wind-heat is seen as resulting from the combination of wind and heat pathogens. The symptoms include fever with relatively high heat signs, slight aversion to wind, not much sweating, headache, facial redness, coughing, sticky or yellow phlegm, thick yellow nasal discharge, dry throat or red and swollen throat, and other symptoms such as swollen and painful throat, nasal congestion, and dry mouth. The wind-heat type of cold in Chinese medicine generally corresponds to what is considered the common cold and influenza in Western medicine, both of which are recognized as viral infections. Therefore, the wind-heat cold is contagious, and patients should maintain a certain distance from others.

What should a baby eat when they have a cold?

During a cold, both babies and adults generally prefer liquid food over solid food. Babies who haven't started on solid food should drink as much milk as possible. For those who are beginning to eat solid foods, in addition to drinking more milk, you can also appropriately increase their intake of plain water and rice porridge. Older children, besides the aforementioned, can also appropriately consume some light soups and can increase their intake of fresh vegetables and fruits. These can be made into vegetable purees or juiced according to the baby's needs. Babies are more prone to dehydration when they have a cold or fever. To prevent dehydration or treat mild dehydration, fresh apple juice can be used as a substitute. For moderate or severe dehydration, seek medical attention promptly; the doctor will take necessary measures for rehydration.

What will happen if you take medicine for wind-heat cold when you have a wind-cold cold?

The treatment principle for colds caused by wind-cold is to use pungent and warm herbs to expel the pathogen through sweating and to disperse wind-cold. The medications for wind-heat colds mainly focus on using pungent and cooling herbs to expel the pathogen, and the treatment principles for the two are completely opposite. If medications for wind-heat cold are taken for a wind-cold cold, it might lead to a worsening of the trapped cold, causing mild fever, more severe headache, and body aches, along with nasal congestion and a runny nose with clear discharge. At this point, it is necessary to stop using the medication for wind-heat colds and switch to medications for wind-cold colds, or, if the condition is severe, seek a face-to-face consultation with a doctor.
