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.

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.

Pneumonia symptoms in children

Children presenting with pneumonia primarily exhibit symptoms related to respiratory infections, with fever often as a typical manifestation. Common symptoms include sudden chills, high fever, fatigue, headache, nausea, and vomiting, followed by an irritative dry cough. As the condition progresses, the dry cough turns into a productive cough with phlegm, accompanied by difficulty breathing, chest pain, and expectoration. Some may also show signs of oxygen deprivation such as cyanosis of the lips and changes in nail color. Active chest X-ray and routine blood tests are necessary for diagnosis.

Is the pneumonia vaccine self-funded?

The pneumonia vaccine is primarily aimed at preventing pneumonia caused by Streptococcus pneumoniae infection. Streptococcus pneumoniae is the most significant and common bacterium causing pneumonia worldwide. This bacterium is also the most common cause of community-acquired pneumonia in children and is the main pathogen causing otitis media, meningitis, and bacteremia in children. Currently, there are two types of pneumonia vaccines available in China: the 23-valent polysaccharide vaccine, which is suitable for people over two years old, and the 7-valent vaccine, which is suitable for infants under two years old. According to the regulations on vaccine distribution and vaccination management implemented in our country, vaccines are clearly divided into two categories: the first category includes vaccines provided free by the government to citizens, who are required to be vaccinated according to government regulations; the second category includes other vaccines that are paid for and voluntarily received by citizens. The pneumonia vaccine belongs to the second category, which is a self-funded vaccine.

How long does the pneumonia vaccine last?

After receiving the pneumonia vaccine, the body generates an immune response that produces antibodies. Typically, these antibodies provide lifelong immunity. Patients with weak constitutions might need a booster shot every 3-5 years after vaccination, which generally can also lead to lifelong immunity. Vaccinations should be administered at local, formal medical institutions. One can visit the local centers for disease control and prevention to get vaccinated. During the vaccination period, if there are any adverse reactions, they should be addressed promptly. After receiving the vaccine, it is advisable to remain at the medical facility for half an hour for observation before leaving, to prevent the occurrence of adverse reactions.
