How Do You Contract Bacterial Pneumonia

If I Am Not Sure What Pathogen Is Causing The Infection What Anti

What doctors want you to know about avoiding pneumonia

Chronic pneumonia is generally not a medical emergency, and the clinician has adequate time to conduct a reasonable assessment before having to decide on specific therapy. In most circumstances, empirical therapy is initiated once adequate diagnostic studies have been obtained. With the suspicion of aspiration pneumonia due to mixed aerobic and anaerobic bacteria, the combination of pipercillin/tazobactam or ampicillin/sulfabactam plus vancomycin or nafcillin is often utilized. Metronidazole may be added to this regimen if broader anaerobic coverage is desired.

For patients with respiratory samples revealing acid fast organisms, the patient should be placed in respiratory isolation and four-drug therapy with rifampin, isoniazid, pyarzinamide, and ethambutol should be initiated until confirmation of the organism as M. tuberculosis or a nontuberculous mycobacteria. Table I lists agents that typically cause chronic pneumonia.

What Are The Symptoms Of Pneumonia

The symptoms of bacterial pneumonia include:

  • Bluish color to lips and fingernails

  • Confused mental state or delirium, especially in older people

  • Cough that produces green, yellow, or bloody mucus

  • Fever

Mycoplasma pneumonia has somewhat different symptoms, which include a severe cough that may produce mucus.

Is Bacterial Pneumonia Contagious

Whether or not bacterial pneumonia is contagious depends upon the type of bacteria causing the infection. In many cases, people contract pneumonia when bacteria they normally carry in the nose or throat are spread to the lungs. Most kinds of bacterial pneumonia are not highly contagious. However, pneumonia due to Mycoplasma pneumoniae and tuberculosis are exceptions. Both these types of bacterial pneumonia are highly contagious. These are spread among people by breathing in infected droplets that come from coughing or sneezing, similar to the spread of viral infections.

What Can I Do To Feel Better If I Have Pneumonia

  • Finish all medications and therapies prescribed by your doctor. Do not stop taking antibiotics when you start feeling better. Continue taking them until no pills remain. If you dont take all your antibiotics, your pneumonia may come back.
  • If over-the-counter medicines to reduce fever have been recommended , take as directed on the label. Never give aspirin to children.
  • Drink plenty of fluids to help loosen phlegm.
  • Quit smoking if you smoke. Dont be around others who smoke or vape. Surround yourself with as much clean, chemical-free air as possible.
  • Use a humidifier, take a steamy shower or bath to make it easier for you to breathe.
  • Get lots of rest. Dont rush your recovery. It can take weeks to get your full strength back.

If at any time you start to feel worse, call your doctor right away.

What Consult Service Or Services Would Be Helpful For Making The Diagnosis And Assisting With Treatment

Pneumonia: Overview and More

If you decide the patient has chronic pneumonia, what therapies should you initiate immediately?

If the patient with chronic pneumonia is unable to produce adequate sputum samples, then a pulmonologist is most helpful in obtaining a deep specimen. Less commonly, a thoracic surgeon is needed to obtain tissue from an open lung biopsy, often using the video-assisted thorascopic surgery procedure. An infectious disease specialist can be very helpful with respect to considering less common diagnoses, especially those not evident following routine diagnostic studies.

For most patients presenting with chronic pneumonia, the condition does not constitute a medical emergency. Accordingly, there is usually time to establish a presumptive diagnosis before initiating antimicrobial therapy. As such, the patient with a clinical diagnosis of chronic pneumonia based on symptoms and abnormal imaging studies should undergo testing of expectorated sputum, if possible, immediately. Routine, acid fast, and fungal smears should be obtained on available specimens.

For suspected non-tuberculous mycobacterial disease, empiric therapy for nontuberculous infection requires considerable knowledge of the patients history for instance, a history of Mycobacterium avium infection in a patient with ongoing immunosuppression might warrant re-initiation of therapy directed at this organism.

A pneumonia diagnosis is based on your medical history, a physical exam, and certain test results. Your doctor determines which type of pneumonia you have based on how you became infected, what your X-ray or lung exam reveals, and which kind of germ is responsible for your infection.

During a physical exam, your doctor will check your vital signs and listen to your lungs with a stethoscope. Decreased breath sounds is an indication of a lot of inflammation, says Michelle Barron, MD, a professor in the division of infectious diseases at University of Colorado School of Medicine in Aurora.

If your doctor suspects pneumonia, they may order further diagnostic tests, such as a chest X-ray to help determine the extent of the infection. Blood tests and an analysis of the patients sputum can pinpoint whats causing the pneumonia. Pulse oximetry measures the oxygen level in your blood .

What Imaging Studies Will Be Helpful In Making Or Excluding The Diagnosis Of Chronic Pneumonia

Routine chest radiographs are almost always abnormal among patients with chronic pneumonia. In the absence of typical radiographic findings on chest x-ray, CT, or chest MRI, it is difficult to make a diagnosis of this disorder. The radiographic abnormalities found among patients with chronic pneumonia are highly varied. As noted, an infiltrate of some sort is virtually always present, but may vary from patchy infiltrates with bronchopneumonia, lobar consolidation, infiltrates with pulmonary cavitation, those that are associated with one or more dense, well-circumscribed pulmonary nodules, and infiltrates associated with chronic diffuse pulmonary infiltration with or without fibrosis.

Patients with chronic pneumonia and patchy infiltrates or lobar consolidation can be a manifestation of mixed aerobic and anaerobic infection. Necrotizing pneumonia due to Pseudomonas aeruginosa, Staphylococcus aureus, Nocardia spp, Actinomyces spp, blastomycosis, cryptococcosis, and paracoccidioidomycosis are common examples. Necrotizing pneumonia associated with pulmonary cavitation is often a manifestation of lung abscess, complicating aspiration pneumonia due to mixed aerobic and anaerobic bacteria, tuberculosis, other non-tuberculous mycobacterial infections, chronic cavitary histoplasmosis, blastomycosis, nocardiosis, coccidioidomycosis, and several noninfectious conditions, such as ANCA-positive microvascular angiitis, bronchogenic carcinoma, and lymphoma.

Treatment Of Viral Infections

There are not as many choices for treating viral pneumonia. Oseltamivir , zanamivir , and peramivir have been the recommended drugs for influenza A or B infections, but some strains of influenza A are resistant to them. Generally, the use of these drugs is only recommended if they can be started in the first 48 hours of symptoms. Taken early, these medications may be effective in reducing the severity and duration of illness. However, treatment initiated even after 48 hours may benefit children with severe disease.

Intravenous immunoglobulins may be used in immunodeficient children who develop some viral pneumonias, as they have been shown to improve outcomes.

People with viral pneumonias are at risk for what are called “superinfections,” which generally refers to a secondary bacterial infection, usually caused by S pneumoniae, S aureus, or H influenzae. Doctors most commonly recommend treatment with amoxicillin-clavulanate, cefpodoxime, ceftriaxone, cefuroxime, or a newer fluoroquinolone if these secondary infections occur.

People with pneumonia caused by varicella-zoster and herpes simplex viruses are usually admitted to the hospital and treated with intravenous acyclovir for 7 days.

No antiviral drugs have been proven effective yet in adults with RSV, parainfluenza virus, adenovirus, metapneumovirus, coronaviruses, or hantavirus. Treatment is largely supportive, with people receiving oxygen and ventilator therapy as needed.

The Difference Between Viral Pneumonia And Bacterial Pneumonia

How to Get Rid of Pneumonia – Pneumonia Treatment

Treatment is the biggest difference between bacterial and viral pneumonia. Bacterial pneumonia is treated with antibiotic therapy, while viral pneumonia will usually get better on its own. In some cases, viral pneumonia can lead to a secondary bacterial pneumonia. At that point, your doctor may prescribe antibiotic therapy. Your doctor will be able to tell if it has become bacterial pneumonia by a change in your symptoms or signs.

Causes And Risk Factors Of A Klebsiella Pneumoniae Infection

K. pneumoniae infections are typically “nosocomial” infections, which means they’re contracted in a hospital or healthcare setting.

K. pneumoniae

Healthy people usually don’t have to worry about getting K. pneumoniae infections, according to the Centers for Disease Control and Prevention .

The bacteria are not airborne, so you can’t contract a K. pneumoniae infection by breathing the same air as an infected person.

Instead, K. pneumoniae is spread through direct person-to-person contact, such as when someone with contaminated hands touches a wound.

Klebsiella pneumonia

Long courses of antibiotics can also increase a person’s risk of getting a klebsiella infection.

Things That You Can Do To Help Your Child At Home Are

  • Control the fever with the proper medicine and right strength for the age of your child. Fevers lower than 101° F do not need to be treated unless the child is uncomfortable .
  • Give your child plenty of fluids to prevent dehydration.
  • See that your child gets lots of rest.
  • Do not give over-the-counter cough medicines or other OTC medicines without asking the health provider first. The child needs to cough and bring up the phlegm. Coughing is the bodys way of clearing the infection from the lungs.
  • Avoid exposing your child to tobacco smoke or other irritants in the air.

How Can Parents Help

Kids with pneumonia need to get plenty of rest and drink lots of liquids while the body works to fight the infection.

If your child has bacterial pneumonia and the doctor prescribed antibiotics, give the medicine on schedule for as long as directed. Keeping up with the medicine doses will help your child recover faster and help prevent the infection from spreading to others in the family. If your child is wheezing, the doctor might recommend using breathing treatments.

Ask the doctor before you use a medicine to treat your child’s cough. Over-the-counter cough and cold medicines are not recommended for any kids under 6 years old. If your child doesnt seem to be feeling better in a few days, call your doctor for advice.

What Is Pneumonia Symptoms Causes Diagnosis Treatment And Prevention

Pneumonia cause that how it spreads

Pneumonia is a lower respiratory lung infection that causes inflammation in one or both lungs.

Air sacs in your lungs called alveoli can then fill up with fluid or pus, causing flu-like symptoms that can persist for weeks or cause rapid deterioration of breathing leading to hospitalization. Pneumonia doesn’t respond to over-the-counter cold and sinus medicines.

Pneumonia comes in different forms and is caused primarily by bacteria or viruses, which are contagious, and less commonly by fungi or parasites.

The type of germ contributes to how serious the illness can become and how its treated. The severity of an infection depends on many factors, including your age and overall health, as well as where you may have acquired the illness.

How Do You Get Pneumonia

Have you ever been told to bundle up to avoid catching pneumonia? Or told a friend or family member not to walk outside with wet hair because he or she could get it? It might surprise you to find out that neither cold weather nor wet hair can cause you to catch pneumonia. In fact, pneumonia in itself isnt contagious, so you cant really catch it at all.

If you are wondering how do you get pneumonia, or have any other questions about this condition, FastMed can help. We are open 365 days a year to provide treatment for non-life-threatening illness and injuries, as well as ready to answer all of your health related questions.

What Is The Treatment

As in all cases of bacterial infections, antibiotics will be the drugs of choice. The doctor, after determining whether it is Gram positive or Gram negative bacteria, may suggest the use of several medications, such as amoxicillin, cephalosporin or doxycycline.

As there are various treatments, it is necessary to establish the exact gender of the microorganisms causing the disease. With this information, it is possible to choose the most effective therapeutic options for each case.

What to remember about bacteria in the lungs?

Strange as it may be, according to the American Lung Association, there is a vaccine against pneumonia caused by Streptococcus pneumoniae, the most prevalent pathogen.

Doctors recommend it for infants under two years of age, and for adults over 65, as they are typical vulnerable groups. In addition, at the risk of contracting it in another age range, the prognosis is positive if it is treated early and complications do not occur.

Bacteria are essential microorganisms, as they provide protection against pathogens in many of the bodys systems. However, its lack of control can cause health problems.

Therefore, with any suspicion of bacterial infection, it is essential to see a doctor immediately. With prompt treatment, the chances of overcoming the bacterial disease are quite high.

How Did The Patient Develop Chronic Pneumonia What Was The Primary Source From Which The Infection Spread

Most cases of chronic pneumonia due to an infectious etiology result from inhalation of aerosolized organisms or aspiration of oral contents. As it relates to noninfectious causes of the chronic pneumonia syndrome, the lungs may be the primary target of disease , or the lungs may simply be innocent bystanders of a systemic disease .

Knowledge of the demographics and relevant epidemiology is key in trying to narrow ones focus to the potential etiologic agents in determining the specific cause of chronic pneumonia. Age, gender, and race may play important roles in the development of chronic pneumonias.

Occupation and hobbies are also important in the evaluation of these patients. For instance, tuberculosis is an important consideration among healthcare workers, incarcerated individuals, and recent immigrants from high incidence regions. Coccidioidomycosis is an important consideration among rock collectors, laboratory technicians, archeologists conducting excavations, and construction workers exposed to desert dust in endemic areas histoplasmosis is an important consideration in persons exposed to pigeon, starling, or bat roosts, or among those who clean old chicken houses with dirt floors and blastomycosis is an important consideration in forestry workers, heavy equipment operators, and campers and hunters from endemic areas.

Antibiotic Treatments For Community

For a more detailed discussion of the different types of antibiotics, see the “Antibiotic Classes” section below.

Joint guidelines issued in 2019 by the IDSA/ATS recommend that mild CAP in otherwise healthy people be treated with amoxicillin or doxycycline. If the person lives in an area with low S pneumoniae resistance to macrolides, a macrolide antibiotic therapy may also be considered.

The British Thoracic Society recommends amoxicillin, doxycycline, or clarithromycin as alternatives.

Many people with heart disease, kidney disease, diabetes, or other coexisting conditions may still be treated as outpatients.

People with coexisting conditions should be given a macrolide plus a beta-lactam or a fluoroquinolone as monotherapy. Doxycycline can be given as an alternative to a macrolide. Current recommendations call for at least 5 days of antibiotic therapy. People should have no fever for at least 48 hours and no more than one sign of continuing severe illness before discontinuing antibiotics.

Many cases of CAP are caused by S pneumoniae — Gram-positive bacteria that usually respond to antibiotics known as beta-lactams , and to macrolides. However, resistant strains of S pneumoniae are increasingly common. Most resistant strains respond to fluoroquinolones such as levofloxacin , gemifloxacin , or moxifloxacin .

In addition, other important causes of CAP, particularly in younger people, are atypical bacteria, which respond to macrolides , or newer fluoroquinolones.

Choosing The Right Antibiotic

Dozens of antibiotics are available for treating pneumonia, but selecting the best drug is sometimes difficult. People with pneumonia need an antibiotic that is effective against the organism causing the disease. When the organism is unknown, “empiric therapy” is given, meaning the doctor chooses which antibiotic is likely to work based on factors such as the person’s age, health, and severity of the illness.

In adults, the choice of antibiotic therapy depends on the severity of infection and site of care. In all cases, the more quickly antibiotic therapy is started once the diagnosis is made, the better the outcomes. In most cases, the organism causing the pneumonia will not be known before antibiotic therapy is started, so the doctor must choose an antibiotic regimen based on history and symptoms. Later, the therapy may be altered when more information becomes available. To determine the appropriate antibiotic, the doctor must first answer a number of questions:

Once an antibiotic has been chosen, there are still difficulties:

  • Individuals respond differently to the same antibiotic, depending on their age, health, size, and other factors.
  • People can be allergic to certain antibiotics, thus requiring alternatives.
  • People may have strains of bacteria that are resistant to certain antibiotics.

Are Vaccines Available To Prevent Pneumonia


Yes, there are two types of vaccines specifically approved to prevent pneumonia caused by pneumococcal bacteria. Similar to a flu shot, these vaccines wont protect against all types of pneumonia, but if you do come down with pneumonia, its less likely to be as severe or potentially life-threatening especially for people who are at increased risk for pneumonia.

  • Bacterial pneumonia: Two pneumonia vaccines, Pneumovax23® and Prevnar13®, protect against the most common causes of bacterial pneumonia.
  • Pneumovax23® protects against 23 different types of pneumococcal bacteria. It is recommended for all adults 65 years of age and older and children over 2 years of age who are at increased risk for pneumonia.
  • Prevnar13® protects against 13 types of pneumonia bacteria. It is recommended for all adults 65 years of age and older and children under 2 years of age. Ask your healthcare provider about these vaccines.
  • Viral pneumonia: Get a flu vaccine once every year. Flu vaccines are prepared to protect against that years virus strain. Having the flu can make it easier to get bacterial pneumonia.
  • If you have children, ask their doctor about other vaccines they should get. Several childhood vaccines help prevent infections caused by the bacteria and viruses that can lead to pneumonia.
