This form of pneumonia is acquired during or after a hospital stay, and it can be severe and even fatal, according to the National Library of Medicine. Other bacterial pneumonia symptoms include:īacterial pneumonias tend to be more serious, with more noticeable symptoms than other types of pneumonia. A cough that produces discolored mucus in the presence of fever and shortness of breath can be a classic sign of bacterial pneumonia. Most bacteria that cause pneumonia are pyogenic bacteria, which means they form pus, a combination of debris from serum, dead bacteria, and white blood cells. It's recommended for all children younger than 5 and is usually given to infants starting at 2 months old, notes the CDC. Haemophilus influenzae type B (Hib) infection can be prevented with a vaccine, called the Hib vaccine. Mycoplasma pneumoniae usually infects younger adults who work in crowded areas, such as schools, homeless shelters, or prisons, according to the CDC.Ĭhlamydophila pneumoniae causes a mild pneumonia infection that usually affects people older than 60, per the CDC. Anyone younger than 19 should not get PCV15 or PCV20.Children younger than 2 should not get PPSV23.PPSV23 (Pneumovax23) is recommended for children 2 through 18 years old with certain medical conditions and adults 19 years or older who receive PCV15.Adults 65 and over and younger adults with certain medical conditions, who have never received any pneumococcal conjugate vaccine, should receive PCV15 (Vaxneuvance) or PCV20 (Prevnar 20). If PCV15 is used, it should be followed by a dose of PPSV23.All babies and children under 2 should receive a dose of PCV13 (Prevnar 13), as should children 18 and under with certain medical conditions.The CDC recommends that all children under 2 and adults 65 or older get vaccinated, and clarifies that: The CDC recommends two kinds of pneumonia vaccines: pneumococcal conjugate vaccines (PCV13, PCV15, and PCV20), and pneumococcal polysaccharide vaccine (PPSV23). Streptococcus pneumoniae, also known as pneumococcus, is the most common cause of bacterial pneumonia in adults, called pneumococcal pneumonia, according to the American Lung Association. Legionella pneumophila, the cause of Legionnaires' disease, or Legionellosis.Types of bacteria that cause pneumonia include: This type of pneumonia may affect just one area of the lung and is referred to as lobar pneumonia, notes the Mayo Clinic. And it can be spread by people who don’t exhibit any symptoms.īacteria are a common cause of pneumonia in adults, according to the National Heart, Lung, and Blood Institute.īacterial pneumonia may follow a viral infection, such as a cold or the flu (influenza). Coughing, sneezing, touching, and even breathing, notes the American Lung Association, can spread pneumonia from person to person. Pneumonia can be transmitted a number of ways. If you catch germs that cause pneumonia, your chance of developing the disease depends on your age, health, and lifestyle. Legionnaires' disease, which is caused by the bacteria Legionella pneumophila, may pose a threat only to people exposed to a contaminated air-conditioning system. It has also been linked to droplets inhaled at whirlpools, spas, or fountains. Some types of pneumonia spread only in certain environments. In general, viral pneumonia is more likely to spread from person to person than pneumonia caused by a bacteria or fungus. You can encounter the germs that cause pneumonia in the most common of places, and your daily environment may contribute to how susceptible you are to the disease.įor example, children in school or day care facilities can easily catch viruses from one another, which makes them more prone to viral pneumonia. But pneumonia caused by fungi is not contagious. It depends on the type of pneumonia - some forms of the infection, such as bacterial or viral pneumonia - can be spread from person to person, notes the Cleveland Clinic.
