Childhood pneumonia is an infectious disease that not only presents symptoms related to the respiratory system but also may include symptoms from the gastrointestinal tract, such as vomiting, diarrhea, loss of appetite, and abdominal distension. Therefore, the diet for pneumonia must be light and easy to digest. For instance, if the child is breastfed, the mother should consume a light and digestible diet. If the child is fed with cow's milk, the milk can be diluted appropriately to aid digestion. Supplementary foods can generally include thin porridge, noodles, rice paste, vegetables, and fruits, as well as a moderate amount of lean meat and eggs, but not in excess. Oily and spicy foods should not be included.

Do you have a runny nose with pneumonia?

In clinical settings, pneumonia patients exhibit varying accompanying symptoms depending on the type of pneumonia. Particularly in very young infants, the early symptoms might primarily include nasal congestion, runny nose, sneezing, and even fever, without obvious coughing symptoms. In some newborns, pneumonia can be diagnosed through auscultation at this stage. In adults, certain types of pneumonia, such as those caused by viral infections, may not receive timely and effective anti-infective or antiviral treatment initially. In these cases, the condition can worsen and spread, leading to pneumonia, with some patients also experiencing symptoms of a runny nose. Of course, conditions like most cases of mycoplasma pneumonia, bacterial pneumonia, and lung abscesses that cause pulmonary inflammation usually do not involve a runny nose. Therefore, in clinical practice, if pneumonia is accompanied by a runny nose, it is usually due to specific circumstances of the illness.

Is pneumonia contagious?

Pneumonia can be divided into many types, including viral pneumonia, bacterial pneumonia, and those caused by special bacteria such as tuberculosis bacillus, and atypical bacteria such as Legionella, Mycoplasma, Chlamydia, etc. Generally, pneumonia does not cause large-scale disseminated transmission, because most people have normal immune systems that can resist these less virulent bacteria; however, in populations with lower immunity, inhaling droplets from patients with bacterial pneumonia can potentially lead to pneumonia. However, pneumonias caused by "SARS", anthrax, pneumonic plague, etc., are highly contagious and can cause large-scale transmission through droplets, and these are strictly controlled infectious diseases in our country. In cases of open tuberculosis, the patient's sputum and cough droplets might contain the pathogen, which could then infect those in close contact. Infectious pneumonia typically has an abrupt onset, with an incubation period of 2-10 days, and fever as the initial symptom, generally above 38℃, possibly accompanied by chills, coughing, scant sputum, occasional bloody sputum, palpitations, shortness of breath, and in some cases, difficulty breathing. It may also be accompanied by muscle soreness, headaches, joint pain, fatigue, and diarrhea.

"Does a weakly positive Mycoplasma pneumoniae indicate pneumonia?"

During the testing process, if Mycoplasma pneumoniae shows a weakly positive result, this does not necessarily indicate that the person has pneumonia. A weakly positive result for Mycoplasma pneumoniae only suggests a possible infection, but does not confirm pneumonia. If there is a suspicion, further investigation, such as chest radiography, should be conducted. If chest radiography reveals changes in lung patterns or patchy areas in the lungs, then it can be considered that the person may have Mycoplasma pneumoniae pneumonia. If the chest radiography is normal, it cannot be concluded that the person has pneumonia.

Differential Diagnosis of Pediatric Pneumonia

Childhood pneumonia needs to be differentiated from other respiratory diseases such as bronchial foreign bodies, bronchial asthma, and pulmonary tuberculosis. A bronchial foreign body generally has a history of inhalation of foreign objects, sudden choking coughs, and a chest X-ray might indicate atelectasis or pulmonary emphysema. If the foreign body has been present for a long time, the disease course is prolonged and may lead to secondary infections, similar to pneumonia or concurrent with pneumonia. The differentiation of bronchial foreign body involves detailed medical history inquiries to check for inhaled foreign objects, then using symptoms and auxiliary examinations like chest X-rays for confirmation. Bronchial asthma, especially in children, might not always present with obvious wheezing attacks but rather persistent coughing. The X-ray might show increased and disordered lung markings and pulmonary emphysema, which can easily be confused with pneumonia. Typically, children with bronchial asthma have an allergic constitution and generally require pulmonary function tests and other auxiliary examinations to differentiate from pneumonia. Pulmonary tuberculosis generally occurs in those with a history of contact with tuberculosis patients. Their tuberculin skin test is positive, and X-rays may show features of tuberculosis lesions in the lungs, which can be used to differentiate from pneumonia.

Can pneumonia heal by itself?

Pneumonia is generally not self-healing; only a few pneumonia cases caused by specific pathogens, which lead to milder infections, can heal by themselves, such as pneumonia caused by Mycoplasma pneumoniae, which is self-limiting and can heal. However, most cases of pneumonia require standard treatment, such as pneumonia caused by Streptococcus pneumoniae and infections caused by Staphylococcus aureus. Therefore, if diagnosed with pneumonia, it is essential to seek immediate medical attention at a hospital. Relying on self-healing is unrealistic since self-healing cases are rare, and most pneumonia cases require standard treatment to recover.
