what is pneumonia;

pneumonia is inflammation of the airspaces(alveoli; singular alveolus) in the lung most commonly caused by infections. Bacteria, viruses, or fungi (infrequently) can cause the infection.

there are also a few noninfectious types of pneumonia that are caused by inhaling or aspirating foreign matter or toxic substances into the lungs.

what are the symptoms of pneumonia;

symptoms and signs o pneumonia may be mild or severe and depend upon someone's overall state of health as well as the type of organism causing pneumonia.

severe symptoms of pneumonia include

⦁ cough

⦁ chest pain when breathing or coughing,

⦁ labored breathing or shortness of breath,

⦁ coughing up a problem,

⦁ fever,

⦁ chills,

⦁ fatigue

⦁ Nausea, vomiting, and diarrhea are other possible symptoms that can accompany the respiratory

symptoms

causes;

streptococcus pneumonia, a type of bacteria, is the most common cause of pneumonia.

legionella pneumophila is the bacterial type that causes pneumonia known as legionnaires diseases. other bacteria types that can cause pneumonia includes the bacteria that cause so-called atypical pneumonia,

legionella pneumophila, Mycoplasm pneumonia, and chlamydophila pneumonia.

Haemophilus influenza is a type of bacteria that cause pneumonia. it most commonly causes diseases in babies and children younger than 5 years of age. Adults 65 years or older Amercian Indians and Alaska Natives are also at increased risk for developing H.influenza disease.

the most common cause of viral pneumonia in adults is the influenza virus. a number of different respiratory viruses cause pneumonia in children, such as a respiratory syncytial virus (RSV).

while viral pneumonia tends to be less severe than bacterial pneumonia, there is a risk of developing secondary bacterial pneumonia when viral pneumonia is present.

other virus types that can cause pneumonia include measles and varicella (chickenpox) viruses.

rarely certain viruses may cause lethal pneumonia such as sars (severe acute respiratory syndrome) or MERS( Middle East respiratory syndrome); both diseases are caused by different coronaviruses.

Fungi that cause pneumonia include Cryptococcus, Histoplasma, and Coccidioides. in most individuals, these organisms don't cause illness, but they can cause pneumonia in some people.

fungal infections are most common in those with a weakened immune system due to HIV/AIDS or those taking medications that suppress immune function.

Another infection that is considered a fungal type of pneumonia is Pneumocystis jirovecii, formerly known as a pneumocystis carinii. This organism became known as a frequent cause of pneumonia in patients with HIV/AIDS.

Treatment:

Antibiotic medications are the treatment of choice for pneumonia caused by bacterial and fungal infections. the exact choice of medications depends on many factors, including the following;

⦁ the organism responsible for the infection

⦁ the likelihood that the organism is resistant to certain antibiotics

⦁ the patients underlying health condition

⦁ about 80% of cases of the cap can be managed at home with the patient taking oral antibiotics.

there are rumors of treatment regimens available. initial treatment (before the causative organism has been identified) is called empiric treatment and is based upon the organism most likely to be responsible for the illness.

once the exact organism has been identified in the laboratory and susceptibility testing performed to determine which antibiotics are effective,

the treatment regimen can be further individualized. over-the-counter pain and fever-reducing medications may be recommended for some people in addition to antibiotics or antiviral drugs for symptom relief.

Do not take cough or cold medications when suffering from pneumonia without a doctor's approval.
