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.

How to take care of children with pneumonia

Children with pneumonia need comprehensive and general treatment, and care should be mindful of the following: First, indoor air should be circulated, with a temperature of 18~20°C and humidity at about 60%. Second, provide a nutrition-rich diet. For severe cases where the child has difficulty eating, parenteral nutrition can be given. Third, frequently change the child's position to reduce pulmonary congestion and facilitate the absorption of inflammation. Fourth, pay attention to isolation to prevent cross-infection. Additionally, it is important to monitor and supplement electrolytes and fluids, correct acidosis and electrolyte imbalances. Appropriately supplementing fluids helps moisten the airways, but care should be taken with the speed of fluid administration, as too fast a rate can increase the burden on the heart.

How many days does the novel pneumonia take to develop?

After being infected with the novel coronavirus pneumonia, symptoms generally appear within three to seven days, with the shortest onset reported within one day and the longest at 27 days. However, most patients develop symptoms within two weeks, typically exhibiting respiratory symptoms post-onset. The novel coronavirus primarily attacks the lower respiratory tract, including the trachea, bronchi, and lungs. Patients often experience recurring fever, with temperatures generally ranging between 38 to 39°C, lasting over 72 hours, accompanied by significant coughing. In the early stages, there is usually no noticeable expectoration, presenting as a dry cough. Most patients also experience significant fatigue. If the condition progresses, patients may suffer from shortness of breath and decreased blood oxygen saturation, leading to apparent respiratory distress. In severe cases, patients may experience respiratory failure and even death.

Types of Pneumonia

Now let's talk about what pneumonia is and its classification. Pneumonia refers to inflammation of the terminal airways, alveoli, and pulmonary interstitium. It can be caused by pathogenic microorganisms, physicochemical factors, immune damage, allergies, and drugs. Bacterial pneumonia is the most common type of pneumonia and is also one of the most common infectious diseases. The classification of pneumonia generally involves several aspects: First is the anatomical classification: from an anatomical perspective, it can be divided into lobar pneumonia (alveolar pneumonia), bronchopneumonia (bronchial pneumonia), and interstitial pneumonia. Second, the classification based on etiology, which mainly includes the following aspects. The first is bacterial pneumonia, which includes Streptococcus pneumoniae pneumonia, Staphylococcus aureus pneumonia, Klebsiella pneumoniae pneumonia, Haemophilus influenzae pneumonia, Pseudomonas aeruginosa pneumonia, and Acinetobacter baumannii pneumonia, etc. The second point is pneumonia caused by atypical pathogens such as Legionella, Mycoplasma, and Chlamydia. The third is viral pneumonia. The fourth refers to fungal diseases or fungal pneumonia. The fifth is pneumonia caused by other pathogens: such as rickettsiae, parasites. The sixth is pneumonia caused by physicochemical factors: such as radiation pneumonia, inhalational pneumonia, and lipid pneumonia. The third category is classification by the environment of illness, which can be divided into two types: the first is community-acquired pneumonia, and the second is hospital-acquired pneumonia.

Is pneumonia serious?

Is pneumonia serious, and what will happen if it worsens or goes untreated? Severe pneumonia can lead to septic shock and can even be life-threatening. If pneumonia is not treated or not treated thoroughly, it can deteriorate into the following conditions: First, it can cause lung abscesses and empyema, and even lead to pericarditis, meningitis, and more; Second, the infection can enter the bloodstream, causing bacteremia and even septic shock; Third, the patient's continuous high fever can lead to febrile convulsions and even the possibility of coma; Fourth, extensive pneumonia can reduce the function of the alveoli, causing hypoxia and carbon dioxide retention. Hypoxia can affect the function of the nervous system, and patients with severe pneumonia may experience drowsiness, irritability, and even convulsions and coma.

What should a child with pneumonia eat?

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.
