If you have pneumonia, the air sacs in your lungs become inflamed as a result of the infection. Although pneumonia is caused by bacteria, viruses, fungi and chemicals, it can affect any lung at any time. The infection causes inflammation in the air sacs in the lungs, called alveoli, and they fill with fluid and pus that can make breathing difficult. The alveoli are a part of the lungs responsible for breathing the air and blood flow to them. This type of pneumonia can occur when you come into contact with a surface or object contaminated with bacteria or viruses. This causes pneumonia. Viral and bacterial pneumonia can spread from person to person via the respiratory tract or even through direct contact between people.
Pneumonia in adults is usually a pneumococcal infection caused by a bacterium called Streptococcus pneumoniae, but many other bacterial species, including Haemophilus influenzae and Staphylitis aureus, can cause pneumonia. It can be difficult to tell what causes a particular case of pneumonia, so it is usually caused by either bacterial or viral infections. A viral infection, such as the cold, can promote streptococcal pneumonia by causing excessive secretion of fluid from the airways. A common cause of pneumonia in children is a bacterial infection of the lungs, usually caused by a bacterium.
Patients with bacterial pneumonia typically suffer chest pain caused by excessive secretion of fluid from the airways, as well as pneumonia and loss of airway space. Diagnosis is made by taking a culture of organisms from the patient’s sputum, bacteria in the airways and other signs and symptoms. A person may have difficulty breathing, coughing or fever. Occasionally, chest or abdominal pain and vomiting occur, but these are more common in older people with a history of pneumonia or other respiratory diseases. Pneumonia is often caused by a combination of bacteria in the airways, such as Streptococcus pneumoniae, Pseudomonas aeruginosa and Klebsiella pneumonia.
Bacterial pneumonia usually develops quickly, often within a day, and viral pneumonia tends to develop slowly over several days. Most people who develop pneumonia first have a viral infection, such as a cold or flu, which causes the same symptoms as bacterial pneumonia, but with a more severe form of the disease. People with bacterial pneumonia can be treated with antibiotics and are usually infected with viral pneumonia.
Inflammation of the pneumonia causes pain when breathing and coughing, which causes inflammation of the mucous membranes. In babies and children, symptoms are less specific and may not show clear signs of a chest infection, but in adults, they can cause severe coughing and fever. Sometimes the only sign of a child can be rapid breathing, but often if pneumonia is present in the lower part of the lung, there are no breathing problems, but fever, abdominal pain or vomiting. If pneumonia is caused by bacteria, an infected child is more likely to develop a high fever and rapid respiratory failure, and may become ill for a few days or weeks, sometimes even months. However, if it is caused by a virus, the symptoms can be gradual and less severe than with bacterial pneumonia.
Anyone can contract pneumonia, but babies, toddlers and the elderly are particularly vulnerable to the dangers of the disease. Pneumonia is the most common infectious cause of death in children, with about 15% of deaths being caused by children under five. Children are usually vaccinated routinely against hemophilus influenza and whooping cough at 2 months of age. Pneumonia is an acute infection of the lungs that causes pus or fluid to fill the alveoli of one or both lungs. There are several types of pneumonia, but pneumococcal pneumonia is the leading cause of death in children under five. Pneumonia is a respiratory infection that affects the lungs and leads to the loss of air sacs that make up the bulk of the lungs and help you breathe.
The infection causes fluid or mucus to fill the alveoli, limiting the amount of oxygen that gets into the sac and making breathing painful. There are many types of pneumonia caused by various forms of infection, but it is common for a person’s pneumonia to begin as a result of an infection in the bloodstream, which can also occur in other infections. If the infection enters the lungs, pneumonia can be slightly worse, especially in people with asthma.
When pneumonia is caused by bacteria, a person quickly becomes ill, develops a high fever and difficulty breathing. If a disease is caused by a virus, the disease may be less severe and occur more slowly. A common cause of bacterial pneumonia is pneumococcal germs, although doctors are not always sure where pneumonia comes from. Viral pneumonia can develop from a cold or flu and exhibit symptoms similar to those of a cold or flu. It can lead to high fever, shortness of breath and difficulty swallowing, as well as severe coughing and vomiting.
