What are the common diseases in infants?

Common infant illnesses mainly include the following categories: 1. Respiratory infections: Such as colds, laryngitis, bronchitis, etc. Due to infants' weaker immune systems, they are susceptible to viral or bacterial infections, presenting symptoms such as fever, cough, and nasal congestion. 2. Digestive system issues: Such as indigestion and diarrhea. These may result from the infant's immature intestinal function or improper food intake, with common symptoms including abdominal distension, abdominal pain, nausea, and vomiting. 3. Skin conditions: Such as eczema and diaper rash. Infants have delicate skin that is easily irritated by external factors, leading to symptoms like redness, swelling, and itching. 4. Thrush and hand-foot-mouth disease: Thrush is caused by oral candidiasis, while hand-foot-mouth disease results from enterovirus infection. Both conditions present with symptoms such as blisters and ulcers on the oral mucosa or on the hands and feet. Parents should closely monitor their infant's health condition and seek medical attention promptly upon noticing any abnormalities.
