![]() ![]() Less often, you can get pneumonia from touching an object or surface that has the germ on it and then touching your nose or mouth. These droplets can then be inhaled by close contacts. Pneumonia is mostly spread when people infected cough, sneeze or talk, sending respiratory droplets into the air. Yes, some types of pneumonia are contagious, meaning it spreads from person to person. This fungus is found throughout the United States in bird droppings and soil contaminated with bird droppings. This fungus is found in the Ohio and Mississippi River Valleys. This fungus is found in Southern California and the desert Southwest. The following are three fungi that occur in the soil in some parts of the United States and can cause some people to get pneumonia. It occurs in people who have weak immune systems due to HIV/AIDS or the long-term use of medicines that suppress their immune systems, such as those used to treat cancer or manage organ transplants. Pneumocystis pneumoniais a serious fungal infection caused by Pneumocystis jirovecii. Fungiįungal pneumonia is most common in people with chronic health problems or weakened immune systems, and in people who are exposed to large doses of certain fungi from contaminated soil or bird droppings. Viral pneumonias may be complicated by a secondary invasion of bacteria, with all the typical symptoms of bacterial pneumonia. ![]() Read about the connection between the flu and pneumonia. This pneumonia is most serious in people who have pre-existing heart or lung disease and pregnant women. ![]() The virus invades the lungs and multiplies however, there are almost no physical signs of lung tissue becoming filled with fluid. Viral pneumonia caused by the influenza virus may be severe and sometimes fatal. Recovery may take months before symptoms ease. As the lungs fill with fluid, oxygen exchange becomes more difficult and results in breathing difficulties. Viral pneumonia caused by the SARS-CoV-2 virus generally occurs in both lungs. Most viral pneumonias are not serious and last a shorter time than bacterial pneumonia.ĬOVID-19 pneumonia can be severe, causing low levels of oxygen in the blood and lead to respiratory failure and in many cases a condition called acute respiratory distress syndrome (ARDS). Respiratory syncytial virus (RSV) is the most common cause of viral pneumonia in young children. SARS-CoV-2, the virus that causes COVID-19, and the influenza virus are the most common cause of viral pneumonia in adults. Viruses that infect the upper respiratory tract may also cause pneumonia. Even though these infections are called "atypical," they are not uncommon. These bacteria are referred to as "atypical" because pneumonia caused by these organisms might have slightly different symptoms, appear different on a chest X-ray, or respond to different antibiotics than the typical bacteria that cause pneumonia. ![]() Outbreaks of the disease have been linked to exposure to contaminated water from cooling towers, whirlpool spas, and outdoor fountains. Unlike other bacterial pneumonias, Legionella is not passed from person to person. Legionella pneumophila, which causes a dangerous form of pneumonia called Legionnaire's disease.Chlamydophila pneumoniae, which commonly causes upper respiratory infections year-round, but can also result in a mild form of pneumonia.The illness is often mild enough to go undetected and is sometimes referred to as walking pneumonia. Mycoplasma pneumoniae, a tiny wide-spread bacterium that usually infects people younger than 40 years old, especially those living and working in crowded conditions.Some types of bacteria cause what is known as "atypical" pneumonia, including: Those at greatest risk for bacterial pneumonia include people recovering from surgery, people with respiratory disease or viral infection and people who have weakened immune systems. When this happens, the condition is called lobar pneumonia. Bacterial pneumonia often affects just one part, or lobe, of a lung. It infects over 900,000 Americans every year.īacterial pneumonia can occur on its own or develop after you've had a viral cold or the flu. Pneumococcal pneumonia is caused by the Streptococcus pneumoniae germ that normally lives in the upper respiratory tract. The most common type of bacterial pneumonia is called pneumococcal pneumonia. ![]()
