Can pneumonia recur? It should be decided based on an individual's constitution. If one has normal immunity and a good constitution, generally, it will not recur after recovery. If one is frail or has low immunity, there is also a certain chance of recurrence clinically. Therefore, it is important to timely adjust the constitution and enhance immunity. One should drink more water, quit smoking and alcohol, avoid exposure to smoke, dust, second-hand smoke, and irritating chemicals, and do more aerobic and endurance exercises. This can help improve the body's immune capabilities and aid in disease recovery.

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.

Can pneumonia vaccines prevent mycoplasma pneumonia?

There are currently two types of pneumonia vaccines available domestically: the 23-valent polysaccharide vaccine and the 7-valent or 13-valent vaccines. These vaccines primarily prevent infections caused by certain serotypes of Streptococcus pneumoniae. The pneumonia vaccines cannot prevent Mycoplasma pneumonia, as Mycoplasma and Streptococcus pneumoniae are two different types of pathogens and do not share the same antibodies for protective effects. Thus, the pneumonia vaccines are mainly for preventing diseases related to Streptococcus pneumoniae infections, and are ineffective against Mycoplasma 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.

What are the symptoms of pneumonia?

Pneumonia can have many manifestations, and each person's symptoms can be different. It is highly heterogeneous, varying from mild to severe and can last for short or long durations. The main factors depend on the type of pathogen involved and the state of the body. The most common symptoms of pneumonia are coughing and producing sputum. The cough can be mild or severe and may be accompanied by sputum. The amount of sputum can vary and may be yellow, green, red, or rust-colored. Other possible symptoms include chest pain, difficulty breathing, respiratory distress, and most cases of pneumonia also involve fever. The duration and severity of the fever are somewhat related to the course of the illness. However, a small portion of patients may have atypical symptoms, especially older adults, who may not show direct respiratory symptoms but instead exhibit consciousness disturbances such as coma, confusion, fatigue, and more.

How many doses are there for the pneumonia vaccine?

Currently, there are two types of vaccines commonly used to prevent pneumococcal diseases. One type is the 23-valent polysaccharide vaccine, suitable for high-risk populations over two years old. The other type includes the 7-valent or 13-valent conjugate vaccines, used for vaccinating infants under two years old. The vaccination schedule for the 7-valent or 13-valent vaccines follows a "three plus one" program, which means three primary immunization doses with at least one month between each dose, followed by a booster dose. For the 23-valent vaccine, high-risk individuals over two years old generally require only a single dose; however, immunocompromised patients may need a booster shot, typically recommended five years after the initial vaccination.
