Early signs of meningitis in infants are more insidious and even lack of non-specificity. With the progression of the disease, a variety of symptoms such as generalized aches and pains, poor appetite, fever, lethargy, poor mental health, vomiting, skin rash, etc. may appear. Infantile meningitis is usually caused by bacterial and viral infections. Early symptoms are atypical, insidious, and even lack of non-specificity, making it easy to delay the disease. With the development of the disease, the typical symptoms of meningitis may appear: fever, irritability, progressive aggravation of consciousness, headache, vomiting, neck straightening and other symptoms, in addition, some of them may also have a rash and other manifestations. When infants and young children present with acute fever, accompanied by impaired consciousness, increased intracranial pressure and other manifestations, the possibility of this type of disease should be considered. As the early symptoms of infantile meningitis may be more insidious and lack of specificity, if any neurological discomfort occurs in infants, it is necessary to consult a doctor for a clear diagnosis in a timely manner, and follow the doctor’s instructions to complete the relevant examinations and carry out targeted treatments, so as to avoid delaying the time of treatment, resulting in serious consequences.
